Re: [PHP] GD - import a PNG image and make transparant
Hi Ash,
Thanks for your suggestion. I think this is where my confusion is. I
understand how to use imagecolorallocatealpha() to for example create a 50%
transparant colour, and apply it to a new rectangle for example.
I dont understand how to apply it to a new source image, for example
$src = imagecreatefrompng('test.png');
// Something here (maybe imagecolorallocatealpha()) to make this
50% transparent- either on its own, or make it 50% transparent as part of a
copy onto a new image
I had thought that imagecopymerge would help me with this, but it seems not.
I'm currently looking through Karl's example to see if I can work it out,
but if anyone can point out a super-simple way of achieving the pseudo-code
above, i'd be very grateful!
Cheers,
Alex

How exactly are you setting the opacity for the image? The traditional way
is to use imagecolorallocatealpha() on the source.

Re: [PHP] [GD] Image errors
Ash, Martin,
Seems you are both wandering around the obvious problem...
I suspect that $tipo (in the next line) is *supposed* to be $type - sounds like
a partial Italian translation to me...
So given that $type=imagecreatefrompng (for example, if the mime check returns
'png' - not very reliable, I suspect),
then
$immagine = $type($this-updir.$id.'.png')
should create a GD resource from the file, but the image appears to be empty.
My take on this is:
OP says he gets the same result from
$immagine = imagecreatefromjpeg(this-updir.$id.'.png')
- well I might expect to get an error message if I loaded a PNG expecting it to
be a JPEG, but I certainly wouldn't expect an image.
On some basic tests, I find that mime_content_type() is not defined on my
system, so ignoring that and trying to load a PNG file using imagecreatefromjpeg
results in pretty much the same result as the OP...
Conclusions:
First: if you use Italian for your variable names, don't change half of their
instances to English...
Second: Make sure you actually know the mime type of a file before you try to
load it into GD...
My version of this would test against known image types to try the GD function:
foreach (Array('png','jpeg','gif') as $typeName)
{
$type = 'imagecreatefrom'.$typeName;
$immagine = $type(this-updir.$id.'.png'le);
if (is_resource($immagine))
{
header('Content-type: image/jpeg');
imagejpeg($immagine,null,100);
imagedestroy($immagine);
break;
}
}
header('HTTP/1.0 500 File is not an allowed image type');

hey, look, just 2 lines!
But it doesn't convert the image from whatever came in to a JPEG output, which
is what the OP's code appears to be trying to do (and possibly ought to work...)

public function showPicture( $id ) {

Re: [PHP] GD and Converting a Transparent PNG-8 to a Transparent GIF
Thanks for the reply
I tried the example (below) from the link and still get a gif with
white background. Maybe, you can only do this with PNG-24s...not
PNG-8s?
Anyone else know if this can work?
# Convert the PreExisting PNG Image to a GIF
$img = imagecreatefrompng($pngPath);
$gifAbsolutePath = PROJECT_ROOT_DIR.'/'.$gifDir.'/'.$gif;
$transparentColor = imagecolorallocate($img, 0xfe, 0x3, 0xf4 );
//$ditherHistory = array(); //stores number of times it was transparent
$height = imagesy($img);
$width = imagesx($img);
for($x = 0; $x $width; $x++):
for($y = 0; $y $height; $y++):
$alpha = (imagecolorat($img,$x,$y) 0x7F00) 24;//127 is
completely TRANSPARENT, 0 opaque
//DITHER!
if($alpha3(
$alpha =127-3 ||
(rand(0,127))=(127-$alpha)
)){
imagesetpixel($img,$x,$y,$transparentColor);
}
endfor;
endfor;
imagecolortransparent($img, $transparentColor);
# Save the Image as a GIF in the directory $gifDir

imagedestroy($img);

I can't see the above code doing much useful. the problem is somewhat
more involved, png uses an alpha channel to determine how much
transparency
a given pixel has, with gif a pixel is either transparent or not,
essentially
a given colour in the gif's palette is marked as transparent and all
pixels with that color are therefore shown as transparent.
try the code here (no idea how well it works):
http://demo.pixelsandpages.com/php-tests/images/test.html
and/or dig into the user comments here:
http://php.net/imagecolortransparent
# Save the Image as a GIF in the directory
imagegif($img, $gifAbsolutePath);
Is there another way that works?

The Problem:
The code above works fine in sense of syntax!
bg.png acts as a transparent border for
14416fed5d4f78.jpg to keep the size of bg.png
and not the size of 14416fed5d4f78.jpg so it
doesn't blow up 14416fed5d4f78.jpg. However, the
image comes out black/white and has lost its
color!
I looked all over Google and I've found nothing
so far that's functional to give the new created
png file the correct colors as the original
14416fed5d4f78.jpg. I figure that I'm missing
some small elements to the process of creating
the png
Anyone have any ideas, pointers, advice, or
correct solution to make this possible?

Try this:
$original=imagecreatefromjpeg(mydog.jpg);
$watermark=imagecreatefrompng(copyright.png);
$osx=imagesx($original);
$osy=imagesy($original);
$wsx=imagesx($watermark);
$wsy=imagesy($watermark);
imagecopy($original, $watermark, ($osx-$wsx)/2,

Hi!
I have absolutely no clue if this will work. This has been typed
directly into my mail client, so no guarantees.
?php
function toRGB($color) {
return array('r' = ($color 16) 0xFF, 'g' = ($color 8)
0xFF, 'b' = $color 0xFF);
}
This function returns an array of red, green, and blue from an integer
like 0xFF.
function toColor($r, $g, $b) {
return $r * $g * $b;
}
This function is basically the opposite of the above. (the integer
value from red, green, and blue)
$image = 'smiley.png';
list($w, $h) = getimagesize($image);
$im = imagecreatefrompng($image);
for ($y = 0; $y $h; $y++) {
for ($x = 0; $x $w; $x++) {
Loop through the pixels.
extract(toRGB(imagecolorat($im, $x, $y)));
Take the values from the array return of toRGB so we can use $r, $g,
and $b instead of $array['r'], etc.
if ($r = 0xCC $g = 0xCC $b = 0x33)
After some trial and error (looking at color charts), any red CC,
green CC, and blue 33 is some shade of yellow.
imagesetpixel($im, $x, $y, toColor(($r + $g) / 2, 0, $b));
The expression inside toColor() is my attempt to calculate the correct
shade of red from the shade of yellow.
}
}

I don't understand half of that, can you explain what you did? (it
works) I was more trying to fix my problem then recoding the whole
thing though.
I hope that helps.

Hi!
I have absolutely no clue if this will work. This has been typed
directly into my mail client, so no guarantees.
?php
function toRGB($color) {
return array('r' = ($color 16) 0xFF, 'g' = ($color 8)
0xFF, 'b' = $color 0xFF);
}
This function returns an array of red, green, and blue from an
integer like 0xFF.
function toColor($r, $g, $b) {
return $r * $g * $b;
}
This function is basically the opposite of the above. (the integer
value from red, green, and blue)
$image = 'smiley.png';
list($w, $h) = getimagesize($image);
$im = imagecreatefrompng($image);
for ($y = 0; $y $h; $y++) {
for ($x = 0; $x $w; $x++) {
Loop through the pixels.
extract(toRGB(imagecolorat($im, $x, $y)));
Take the values from the array return of toRGB so we can use $r,
$g, and $b instead of $array['r'], etc.
if ($r = 0xCC $g = 0xCC $b = 0x33)
After some trial and error (looking at color charts), any red CC,
green CC, and blue 33 is some shade of yellow.
imagesetpixel($im, $x, $y, toColor(($r + $g) / 2, 0, $b));
The expression inside toColor() is my attempt to calculate the
correct shade of red from the shade of yellow.
}
}
header('Content-type: image/png');
imagepng($im);
?
:)
I don't understand half of that, can you explain what you did? (it
works) I was more trying to fix my problem then recoding the
whole thing though.
I hope that helps.
The thing is, it returns black. not red.
Oh. Replace the toColor function with the imagecolorallocate function
and add $im as the first parameter.

think it's good to go.

Hi All,
I have done some searching via google and some answers say change
copyimageresampled to copyimageresized etc
I have tried all fixes ... to no avail
I have one image here 1280 x 960 (150 dpi) 24 depth
When using the following it pixelates ...
function createthumb($name,$filename,$new_w,$new_h)
{
$system=explode(.,$name);
$src_img=imagecreatefromjpeg($name);
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x $old_y)
{
$thumb_w=$new_w;
$thumb_h=$old_y*($new_h/$old_x);
}
if ($old_x $old_y)
{
$thumb_w=$old_x*($new_w/$old_y);

imagejpeg($dst_img,$filename);
imagedestroy($dst_img);
imagedestroy($src_img);
}
Which I am of course calling with
createthumb($add,'../pics/'.$largeval,350,263);
Now ... afaik my new sizes are proportional to the big ones ... but it
pixelates :(
However,
Using an image 1600 x 1200 (96 dpi) 24 depth it works and there is no
pixilation
Can someone perhaps assist now?

DPI is completely irrelevant.
the '24 depth' sounds like your using a PNG as input rather
that a JPEG (which your function expects)
your not making sure that the new width height are always
integers. use intval() or ceil() or floor() (depending on your
your and the context)... I have no idea what happens if you pass
floats (or non-numeric data) in the relevant arguments of image*()
functinons but I'm guessing it *could* lead to unexplained weirdness
of some sort.
read the man page for imagejpeg():
http://php.net/manual/en/function.imagejpeg.php
take note of the third argument, personally I always set it to 100,
anything less and clients have a tendency to start complaining about image
quality.

Anyone have any experience running Innodb on raw partition? raw partitions are beneficial only in some old OS/hardware configurations where fsync is extremely slow. In most computers, you only get a 5 % performance improvement from raw partitions. Any thoughts as to best filesystem for Innodb? What about pros/cons of journaled filesystems when in use with Innodb (i.e. transactions)? All major Linux file systems seem to have almost the same performance. [/quote - Heikki Tuuri] Use of MySQL on a RAW partition I limited to InnoDB type; (note the use of 'may' in the quote) [quote] http://dev.mysql.com/doc/refman/5.0/en/innodb-raw-devices.html You can use raw disk partitions as data files in the shared tablespace. By using a raw disk, you can perform non-buffered I/O on Windows and on some Unix systems without filesystem overhead, which may improve performance. [/quote] [quote] A raw device can be bound to an existing block device (e.g. a disk) and be used to perform raw IO with that existing block device. Such raw IO bypasses the caching that is normally associated with block devices. Hence a raw device offers a more direct route to the physical device and allows an application more control over the timing of IO to that physical device. This makes raw devices suitable for complex applications like Database Management Systems that typically do their own caching. [/quote - SCSI HOWTO] Based on what I read utilizing a RAW would probably require most PHP'ers to reconfigure their systems in major ways, including the database type, disk partitions, etc. I don't know about you, but most would consider Heikki Tuuri an expert on MySQL systems and Tuuri's thoughts indicate that RAW partitions vs. file systems are a wash unless you have fsync problems. It would appear that the only benefit comes from not having the file system doing the caching. [previous statement] There are a lot of us using MySQL (and PostGreSQL) along with PHP and in practice we have found that storing images in the database to be less than ideal from both a performance and backup POV. The reasons range from speed to overhead to ease of use. On our hardware. It not only has to do with storing and retrieving BLOB data, but also things like indexing, OS qwirks and the like. [/previous statement] I still stand by this, and amend by saying that using a RAW partition for database storage is typically beyond the needs of most PHP'ers as it gains nothing in performance and requires that much additional maintenance be performed on the database as well as the OS for maintenance of the RAW partition. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] GD to database directly
[snip] ...a lot of stuff started by my original answer... [/snip] While this has been a fine debate I find that the discussion has deteriorated badly. Can we bring it back on point?

Kevin, you have more than once pointed out using a RAW format for operating the data system, what exactly do you mean? The database becomes the OS? If so, how do you set that up? It is something that I am not totally familiar with. If you are talking about RAW photo data I am familiar with that. As far as backup, I have a routine that backs up my databases AND the images, PDF's, DOC's, and other binary file format items that the data system points to. That wasn't hard to set up, and it is very reliable. I never have a problem with integrity. And finally, benchmarking. There would be three benchmarks to be conducted and concerned with here, as I have stated before; PHP and images in the OS's file system PHP and images in the MySQL database PHP and images in the OS's file system pointed to by data stored in the MySQL database. Usually only two are compared. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You're NOT going to sort on it. You're NOT going to filter it based on what's in the binary data. There are ZERO functions internal to SQL that can do anything at all useful with the data. Maybe if MySQL had GD integrated, and you could do: SELECT imagescaled(image, 400, 300) FROM images But it doesn't. And you're not the CIA using AI feature recognition to compare the photos in your DB with an SQL function. You're just shuffling data through layer after layer after layer of DB calls so it can sit on the same damned hard drive, clogging up the DB space, and making HD disaster recovery of the data in the DB far far far more difficult.

RE: [PHP] GD to database directly
[snip] How much of a performance hit? [/snip] Here is an interesting read; http://mysqldump.azundris.com/archives/36-Serving-Images-From-A-Database .html Your system receives a number of file read requests, requesting it to load a number of blocks from the disk into the mysqld process. Eventually, the blocks show up in the buffer cache, and mysqld is woken up, receiving file data for the read requests. But I will say this, in this day and age there may not be the performance hit that we had in days gone by due to improvements in software and hardware, so I may have misspoken. I do believe in a one for one comparison where we use PHP and the file system or PHP and MySQL on the same box that, however minimal, there will be a difference favoring the file system using the same images. I also believe that these methods should be compared to using MySQL to hold data about the image so that the benchmarks could be run like this; PHP + File System PHP + MySQL (where MySQL stores a BLOB) PHP + MySQL (data only) + File System The reason for the last one is that is the likely way these technologies would be used together. I spend a lot of time utilizing the MySQL command line and other similar query analysis tools for MS-SQL and Oracle. Image BLOBs become more of a hindrance than a help at this level because these tools are not designed to properly parse and display the files. This is important because it adds to my bias against storing images in a database. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Additionally, your test isn't really MySQL versus filesystem, it's
PHP+MySQL versus filesystem. Perhaps a more useful comparison would be
PHP+Filesystem versus PHP+MySQL. As in, the same PHP script for both
benchmarks, except one copy uses file_get_contents and echo (Closer
match than readfile, since MySQL would require loading the file into
memory) and the other uses MySQL. This would be a closer match that
would tell us how much latency is induced by the actual database itself
rather than PHP and loading stuff into memory.
Regards, Adam.
I was just running a simple test based on how I work with images. I
usually upload one, resize it on the fly, and save a new image which I
directly link to. Therefore I don't need anything to read and send a
raw image through PHP. If you think that is a valid test, then
perhaps you should use your own time to achive your adequate
benchmark.
As for my script:
?php
$link = mysql_connect('localhost', 'test', 'test') or die('unable to connect');
mysql_select_db('test') or die('unable to select');
$sql = SELECT imagedata FROM images WHERE id = 1;
$result = mysql_query($sql);
$row = mysql_fetch_assoc($result);
header('Content-Type: image/jpeg');
echo $row['imagedata'];
There is an auto inc primary on the id column.
I have APC disabled during this test so that isn't a problem.

This way you could down the road re-do all the sizes if you go through a site redesign or the client chooses they want them 450 instead of 400. =) Via MySQL 4.1 PHP 5.1.4: erics:~ eric$ ab -n500 -c5 http://localhost/fs_vs_db/viewimage_db.php This is ApacheBench, Version 1.3d $Revision: 1.73 $ apache-1.3 Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Copyright (c) 1998-2002 The Apache Software Foundation, http://www.apache.org/ Benchmarking localhost (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Finished 500 requests Server Software:Apache/1.3.33 Server Hostname:localhost Server Port:80 Document Path: /fs_vs_db/viewimage_db.php Document Length:25256 bytes Concurrency Level: 5 Time taken for tests: 4.323 seconds Complete requests: 500 Failed requests:0 Broken pipe errors: 0 Total transferred: 12727000 bytes HTML transferred: 12628000 bytes Requests per second:115.66 [#/sec] (mean) Time per request: 43.23 [ms] (mean) Time per request: 8.65 [ms] (mean, across all concurrent requests) Transfer rate: 2944.02 [Kbytes/sec] received Connnection Times (ms) min mean[+/-sd] median max Connect:0 00.4 010 Processing:1442 12.6 38 147 Waiting: 1442 12.6 38 147 Total: 1442 12.6 38 147 Percentage of the requests served within a certain time (ms) 50% 38 66% 40 75% 44 80% 46 90% 56 95% 67 98% 78 99% 97 100%147 (last request) Raw Image: erics:~ eric$ ab -n500 -c5 http://localhost/fs_vs_db/cloud.jpg This is ApacheBench, Version 1.3d $Revision: 1.73 $ apache-1.3 Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Copyright (c) 1998-2002 The Apache Software Foundation, http://www.apache.org/ Benchmarking localhost (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Finished 500 requests Server Software:Apache/1.3.33 Server Hostname:localhost Server Port:80 Document Path: /fs_vs_db/cloud.jpg Document Length:25256 bytes Concurrency Level: 5 Time taken for tests: 0.624 seconds Complete requests: 500 Failed requests:0 Broken pipe errors: 0 Total transferred: 12775000 bytes HTML transferred: 12628000 bytes Requests per second:801.28 [#/sec] (mean) Time per request: 6.24 [ms] (mean) Time per request: 1.25 [ms] (mean, across all concurrent requests) Transfer rate: 20472.76 [Kbytes/sec] received Connnection Times (ms) min mean[+/-sd] median max Connect:0 10.7 1 5 Processing: 3 56.6 4 131 Waiting:1 46.7 3 130 Total: 3 66.5 5 131 Percentage of the requests served within a certain time (ms) 50% 5 66% 5 75% 5 80% 6 90% 7 95% 10 98% 11 99% 19 100%131 (last request) The time taken per request, though (and that's about all we can get with a concurrency as low as 5) doesn't tell us much.

Perhaps a more useful comparison would be PHP+Filesystem versus PHP+MySQL. As in, the same PHP script for both benchmarks, except one copy uses file_get_contents and echo (Closer match than readfile, since MySQL would require loading the file into memory) and the other uses MySQL. This would be a closer match that would tell us how much latency is induced by the actual database itself rather than PHP and loading stuff into memory.

OK, so that works. So is gd (or one of the required programs) wonky then - I mean 4 out of 5 scripts I downloaded didn't work. I can't see all of these people being bad programmers.., but the funny thing is they all work on Windows.

Well, you may not have the BCmath enabled, and this script will break if
bcmod isn't there, probably without you seeing an error message.
A tip for debugging image scripts - comment out the line like
header(Content-Type: image/jpeg);
and run the script again; if there is an error it will be displayed (error
settings permitting) whereas with the header in place, all you will get is
the broken image icon, most likely.

After my last email I searched around some more and found the following.
/Q: gd keeps saying it can't find png or jpeg support. I did install

/A: Be sure to do make install-headers for libpng and make
install-lib for libjpeg, in addition to make install./
This is basically what you were saying, but as I said these header
files do not exist on their own (for Slackware anyways) and just by
chance I came across the above, but in any event it still doesn't
work. It might be nice though if somewhere in the instructions it
says, hey, you might need to do this.
Then I found this when searching on the jpeg errors I keep getting.
/This error occures becuase the linker (ld) cannot find the jpeg
library./ /You can fix this problem by editing the config.nice file
inside the php4/ /directory and adding / /LDFLAGS='-L/path/to/lib' \ /
/above the ./configure \ /
/For example is your libjpeg.so resides inside /usr/local/lib, you'd
add/ /-L/usr/local./
/Once you've edited the file, remove config.cache and run
./config.nice,/ /after that make; make install; should work./
Since my/// libjpeg.so / is in /usr/lib I put/// LDFLAGS='-L/user' \/
- I still get the same error. If I compile without the jpeg it works
like a charm - so I recompiled libjpeg thinking it may have gotten
screwed up, but same errors.
So the question is, why can't it find these files?
Any ideas on what else I can do. I'm assuming that other people have
this working on Slackware, if so, how did they do it? I posted to that
forum as well and didn't get one answer.
Please always CC the list - you'll get more (and faster) help.
As David suggested, try adding this:
--with-jpeg-dir=/usr --with-png-dir=/usr
to the php configure command.
If that doesn't work, where is the jpeglib.h file?
Mine is in the /usr/include folder, so I use /usr for the --with-jpeg-dir
parameter.
If that file doesn't exist anywhere on your system, you haven't got the
headers installed for libjpeg.

This is the output from ?php var_dump(gd_info()); ?. As far as I can
tell, jpeg support is enabled. It also says it is if I run phpinfo().
Yet is still doesn't work.
Show us some code that doesn't work and you'll probably get some
suggestions.

Beauford wrote: After my last email I searched around some more and found the following. /Q: gd keeps saying it can't find png or jpeg support. I did install libpng and libjpeg. What am I missing?/ /A: Be sure to do make install-headers for libpng and make install-lib for libjpeg, in addition to make install./ This is basically what you were saying, but as I said these header files do not exist on their own (for Slackware anyways) and just by chance I came across the above, but in any event it still doesn't work. It might be nice though if somewhere in the instructions it says, hey, you might need to do this. Then I found this when searching on the jpeg errors I keep getting. /This error occures becuase the linker (ld) cannot find the jpeg library./ /You can fix this problem by editing the config.nice file inside the php4/ /directory and adding / /LDFLAGS='-L/path/to/lib' \ / /above the ./configure \ / /For example is your libjpeg.so resides inside /usr/local/lib, you'd add/ /-L/usr/local./ /Once you've edited the file, remove config.cache and run ./config.nice,/ /after that make; make install; should work./ Since my/// libjpeg.so / is in /usr/lib I put/// LDFLAGS='-L/user' \/ - I still get the same error. If I compile without the jpeg it works like a charm - so I recompiled libjpeg thinking it may have gotten screwed up, but same errors. So the question is, why can't it find these files? Any ideas on what else I can do. I'm assuming that other people have this working on Slackware, if so, how did they do it? I posted to that forum as well and didn't get one answer. Please always CC the list - you'll get more (and faster) help. As David suggested, try adding this: --with-jpeg-dir=/usr --with-png-dir=/usr to the php configure command. If that doesn't work, where is the jpeglib.h file? Mine is in the /usr/include folder, so I use /usr for the --with-jpeg-dir parameter. If that file doesn't exist anywhere on your system, you haven't got the headers installed for libjpeg. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
