Make this one be ImageCreateTrueColor()

I believe something changed in the GD library where lo-res internal images
were not promoted to hi-res or something like that...

[PHP] PHP ImageCreateFrom.. malfunctioning in last PHP releases...

[M]

Hello people,

I use ImageCreateFromString PHP functions to resize (thumbnails and so)
dynamically my JPG images.

I use third party WEB hosting provider , so I have no control about new
releases and updates of server softwares.

I have not changed my images in last 3 years (they are used for virtual
stores), they appeared beautiful in these 3 years, but from some days
ago, they are appearing with terrible filter colors (all blue for
instance, some entirely black and so). When bypassing image PHP
functions, images again appear beautiful in my page, but site
performance to show product catalogs gets terrible, not to say
impossible for customers browse on it.

I wrote web provider to check what changed in their PHP environment, but
I am afraid they will answer none has changed.

I use the following sequence of commands to rebuild thumb images:

$orimage = ImageCreateFromString(string) to get original image
from opened JPG file
$thumb =  ImageCreate(new-width, new-height) to create empty new
thumbnail
ImageCopyResized($thumb,$origame,)  to fill thumbnail
ImageJpeg($thumb)  to show thumbnail

I checked by increasing 'quality' parameter  ImageJpeg($thumb,'',100)
but result continue to be wrong.

Is anobody else experiencing these problems lately?, how did you solve
it?

Thanks very much

(I would appreciate cc to [EMAIL PROTECTED] if possible)

Re: [PHP] about the absolutely path

[Richard Lynch]

Because it's Windows, I had to stop the "DNS Client" service -- Or, at
least, that seemed to help...  Maybe I should start that again and test.

Also, I was dumb enough to not have all my VirtualHost's in /etc/hosts,
only it's Windows so it's c:\windows\system32\drivers\etc\hosts (in *THIS*
versions of Windows, not the other versions, where it's some other
directory.  Sheesh!)

And, finally, for reasons beyond my ken:
NameVirtualHost *:80 was no good, but
NameVirtualHost 127.0.0.1:80 was good.
Go figure.

Got it to work, but it feels more like Voodoo than anything else.

Thanks to all, and apologies for this off-topic post to wrap this up.

Hope it forestalls at least one post somewhere in the future.

Hm.  I wonder if I could put something in ?/hosts to do:
[a-zA-Z0-9-]*  127.0.0.1

In other words, if I try to surf to 'example' (not example.com) then I
just want my local Apache VirtualHost settings to kick in, so I can work
on sites locally, without digging around and changing ?/hosts every time.

This might help:
http://php.net/posix-mkfifo

How you would tie stdout to your named pipe...

Or perhaps you could http://php.net/exec something in each process to
re-direct or tee stdin/stdout to your named pipes.

Or...

I dunno, really, just guessing.

"object" is pretty useless...

Unless it's some kind of meta-function that can deal with *ANY* PHP
Object, of course.

[PHP] [ANN] Have fun programming with your kids

[ducasse]

Hi

If you are a parent, an educator or a programmer having kids this is
for you! After 4 years of work, my new book "Squeak: Learn
programming with Robots" will be out soon.

http://smallwiki.unibe.ch/botsinc/

http://www.amazon.com/exec/obidos/tg/detail/-/1590594916/
qid=1117218524/sr=1-1/ref=sr_1_1/002-5642974-5143261?v=glance&s=books
With Bots Inc you will learn how to program robots in an interactive
environment. Bots Inc proposes three teaching approaches: direct
command of robots, scripting robots and programming robots. The book
contains 24 chapters going step by step over topics with a lot of
examples. Bots Inc is fun but it is not a toy, it teaches you 100%
real programming. Bots Inc is built on top of
the rich open-source multimedia Squeak environment that you can also
discover.

My goal is to explain key elementary programming concepts (such as
loops, abstraction, composition, and conditionals) to novices of all
ages. I believe that learning by experimenting and solving problems
with fun is central to human knowledge acquisition. Therefore, I have
presented programming concepts through simple but not trivial
problems such as drawing golden rectangles or simulating animal
behavior. The ideal reader I have in mind is an individual who wants
to have fun programming. This person may be a teenager or an adult, a
schoolteacher, or somebody teaching programming to children in some
other organization. Such an individual does not have to be fluent in
programming in any language. As a father of two young boys I also
wrote this book for all the parents that want to have fun programming
with their kids in a powerful interactive environment. Programming in
Squeak is an interactive, fun but deep experience. The present book 
teaches elementary programming aspects, the following book will 
introduce a new fun

environment and teach object-oriented programming.

Testimonies

"I am using the version of the book on your web site to teach my
oldest daughter Becca some programming. She absolutely loves it. We
are doing the Bot graphics right. My other kids are showing interest
as well. My Fall semester schedule leaves me with almost no time free
but in the Spring I hope to bring Squeak and your book to our
elementary school's "gifted" program." C. David Shaffer

"I'm using the Bot Lab environment for three years and found it
really valuable in teaching computer science concepts for a young
audience (and even less young !). The bots commanded through balloon
(as in comic strips) is a very nice introduction for young children,
and when this aspect is well understood, you can use the Bot
Workspace to teach the notion of script, a first step in programming
languages. The Micro Browser allows children to add new behavior for
their bots, and have fun with their creation. This three-layers tool
- Balloon, Micro Workspace, Micro Browser - offers to the teacher a
fun way to introduce gently the basis of object-oriented programming
concepts. With Bots Inc, learning is playing ! ;-)" Samir Saidani -
University of Caen - France

"I recently started a course with 7th-graders (age about 13 years)
with Stephane's book --- they love it. They all know about syntactic
issues from maths --- in a way they know that an expression in a
formal language must be well formed. So they easily grasp the fact
such as "there must be a colon after the message-name if an argument
follows". Of cause they don't really read the error-messages, they
just see "there must be some error" and they remember the simple
rules. Don't underestimate Smalltalk --- it's easy understandable
because it has a simple and straight-forward design." Klaus Fuller -

Have fun...

Specific type so that users of the function know what they can do with
the returned object from reading the doc.

[PHP] Documenting Code Question

I need some help regarding documenting code. Say you have a 
function/method that takes an object as a parameter and/or returns an 
object.


When documenting, do you specify the specific class of the object when 
listing the datatype in the docblock @param and @return specs or do you 
simply specify "object"?
