base64 & '='

[sims]

When using base64Decode it seems that the '=' or '==' chars
at the end of a base64Encoded string are inconsequential. It
seems to make no difference if one '=', two '==' or none are at the
end of the string being decoded.

Is it safe to assume that any ending equal signs in a base64Encoded
string do not have to be in that string when I decode it?

Re: Linux and AudioClips

[Mark Smith]

In AIF files, the sample rate is stored as a 10 byte ieee floating  
point number - this gave me all sorts of trouble when I was making my  
audio waveform component.


Being a bit of a dunce when it comes to binary bit-twiddling, I  
eventually opened a 'silver support incident' (ie paid for), and Mark  
Waddingham came up with a couple of excellent functions for encoding/ 
decoding such numbers.


I posted the functions  to the list back in January. If you look at  
them, you can see that they are fairly complicated, and so fairly  
easy to screw up.


I wonder if the UBUNTU aif code for reading these 10 byte numbers is  
buggy, producing a number 2 x  what it should be?


Best,

Mark

I've seen at least one base64 decode function (not Rev) where  
stripping a final "=" does affect the output. So, without official  
sanction from RunRev,  I'd be wary of assuming the way Rev handles  
incomplete encoded strings will remain the same in future versions.


But I take it you have a reason you want to drop the "=" characters.

Yup...there is a reason.


I'll rephrase the question: there seems to be either 1 or 2 equal signs placed
at the end of a base64Encoded string. If I display it without any equal signs
but add a single equal sign when I decode the string, would I be safe?

[The "=" seems to be an item which indicates the end of a base64 string.]

iow - does it make any difference if there is 1 or 2 equal signs at the end?
With strings I've tested here it doesn't seem to make a difference.

Copies of your app running on the local net

[Paul Claude]

Two shareware questions:

1) There is a way to determine if there is more than one copy of your app
running on a local net (to check the use of the right shareware license by
your customer)?

2) To create a license code for your customer that include the computer User
Name ($USER - to avoid illegal duplications and distributions), may cause
some contraindication?

Hello Paul,

reply 1) Yes, you can broadcast a UDP request and make all copies on  
the network send (part of) their serial number to compare them with  
the serial number of the newly opened copy of your application.


reply 2) Yes, you can use USER$ on some platforms, but not all. You  
can also use MAC address, label of the hard disk, IP address and  
other characteristics. However, I will never buy software that  
requires me to provide information like this, because I know it will  
be a hassle to install the software on a new machine. Besides, there  
is a hack for each protection measure which makes it difficult to  
decide how much to invest in protection.

Re: Read file with accented characters ?

[Zax]

Thanks for your suggestion.
I tried this function but results are not enough accurate.

It's the same problem with all the functions I have already tried : I'm not
able to recognize a MS Word document saved in "simple text" format from a
BBEdit file saved in Mac format... And I need to recognize them because
BBEdit files need to be translated with the built-in IsoToMac function.

Any ideas ?

I thought that $USER should be valid because: 1) a license is valid, in
effect, only for one user (think about a corporate with hundred of stations
that buy a copy of your app). 2) For a single user with 2 computers, in most
of the cases he will have the same account user name on both, and you can
also add a button in your site to automatically furnish a new code to a
registered user. I don't think to invest very much in protection, but a
simple - universal - license code, will put too easily your app in the
pirates market.

There is a sample UDP client and server in revonline under username

Beware the problem of Firewalls - the Win XP firewall on each Windows

not quite willing to risk setting my own "firewall settings" back to the 
default to see what it does :-) , so it's quite possible and/or quite

Detecting Window's Maximize Window Click

[Rob Cozens]

Hi All,

When I click on the Maximize Window Box with the Message Box open, the 
message I see is "resizeStack".


My stack already has a resizeStack handler that assumes the user has 
resized the stack by dragging the bottomLeft corner.  Obviously a 
resizeStack message resulting from clicking on the Maximize Window Box 
requires different logic.


So how to differentiate between the two?  Once one knows the answer, 
it's obvious; but I was in the process of asking when the light dawned: 
 when the box is clicked, the window dimensions have not changed.  So 
to help others avoid playing the foole...


on resizeStack newWidth,newHeight,oldWidth,oldHeight
		if newWidth = oldWidth and newHeight = oldHeight then -- Maximize Box 
was clicked

Re: Scripting the Paint Tool

[Rob Cozens]

Moi:

What I'm finding is Rev _always_ opens a new image over the entire 
card, despite the fact that an opaque, visible image is already on the 
card.


Bug in Rev or in the documentation?



Answer is...




The documentation might make it clear the image cannot be part of a 
group!


Once I took the signature block image out of the group it was part of, 
everything works fine.


Way cool!

At first glance one wouldn't know it's Rev painting instead of the TPC

Re: Copies of your app running on the local net

[Mark Schonewille]

Hello,

Of course, if there is a firewall in place, it might render any check  
for copies of the software on the network useless. There are  
utilities such as LittleSnitch to prevent programmes from contacting  
the network and the internet. That's why I wrote that there is a hack  
for each protection measure  --there really is. The question is how  
much you want to invest in protection and how much others want to do  
to override this protection.


Currently, I have 5 computers that I use each day (just counted), all  
with a different setup and different user names and passwords. Having  
5 different licenses for each application I am buying means that my  
database for license keys would grow very quickly. It would become  
increasingly complex to do maintenance on the systems I'm using.


If you want me to run the software on only one computer, you really  
don't want to give me more than one user name. This is contradictory  
with your suggestion to provide users with an easy way to get a new  
license key when they want to change their user name.


Suppose that you want to accommodate for the possibility to change  
user names. You would have to supply new license codes all the time.  
This doesn't only undermine the protective power of your licensing  
scheme, it also increases the danger of old license codes being lost  
and found by opportunists. Additionally, it demands an increasingly  
large amount of resources from your support department, due to the  
complexity of your license scheme.


Best,

Mark

That's a great question.

The original post might be rephrased to consider this wording:

What harm would there be in having a normal reg system that doesn't 
attempt to shut down multiple local copies, puts that development time 
into features and marketing, and reconsiders a greater investment in 
anti-piracy technology down the road after there's a sizable installed base?


Most people who pirate software will never become customers anyway. 
Taking funding away from customer-centric enhancements and marketing 
rarely pays bigger dividends than focusing on the experience of the 
legitimate user.

Actually this doesn't work on Windows, Rob... the way resizing is handled is
different between platforms - even just simply resizing the stack by
dragging the bottom right corner is different (Mac sends resizeStack when
you release the mouse; Windows sends it constantly as you're resizing the
stack while the mouse is down).

There's a way to tell the rect of the stack against the windowboundingrect,
but you'd have to subtract the height of the stack's titlebar (which on
Windows is up to the end user).

I'll root around and see if I can find some code to help...

There are times when it would be nice to escape the shackles of

Bottom line question:

Is there a way to apply Unsharp Mask and Levels adjustments to photos

and added later in another thread (Directory Walker Conundrum) on Sun 
May 28, 2006:


I always tell people "Oh yes, the other thing about Revolution, is,  
its rare not to get a solution with 18 hours"


Of course, only if you don't ask for the Cheese In The Moon... no one  
responded to my query as to whether  one could apply unsharpMask to a  
photo in revolution. Like a great sage once said: "You can do  
anything, but don't try to fly like a bird."



The interest of list members in this area is indeed limited.

Two things I can recommend loosely pertaining to your query are Chipp 
Walters' "convolve" stack and DLL (to be downloaded from his website) 
and Derek Bump's adaptation of this stack and DLL that corrects the 
yellow color shift (). Both stacks 
contain 9 filters based on a 3X3 filter matrix, among them sharpen, 
blur, emboss etc., but not unsharp. The filter matrix can be used to 
experiment with own matrix settings.


I had embedded Chipp Walters version into my "ImageFilterDemo" 
() and got responses from 
Chipp and Derek. One interesting thing is that Chipp demonstrated that 
it is possible to script filters (3X3 matrix) completely in Revolution 
without using a DLL, however the execution of such a script is much 
slower than with the help of DLL.


I am experimenting myself with scripted filters, some of which are 
contained in the ImageFilterDemo, about a hundred or so will be 
available shortly in my "Imagedata Toolkit".


I would very much like to see more possibilities for filter use in 
Metacard/Revolution and had asked both Derek and Chipp the following 
questions:


"- Are there more tested and useful examples for filter matrix settings 
available?


- Could such a DLL as "convolve3.dll" be extended to work with larger 
matrices (5X5 etc.) ?


- Would it be possible to produce a DLL to support the use of 8FB-filter 
files (Photoshop plugins) inside Revolution? "


Derek Bump responded to that sympathetically, but mainly in the 
negative, mentioning his workload and other preoccupations.


Chipp Walters has something "in the works", but is rather reticent at 
the moment; we have to wait until his new DLLs and/or stacks for filter 
use are ready for public release.-


Maybe others could chime in here and provide more information.

Best regards,

Wilhelm Sanke

If you need to get rid of one character from the set of characters,  
you might consider the line end.  The line end is part of the  
standard, but the Rev decode does not need it.

HTML entities

[Sarah Reichelt]

Hi All,

I have a field of data that I want to format into a web page. The data
can contain symbols, most likely just the degree symbol but possibly
others. If I get the htmltext of the field, it gives me the correct
entity for the degree symbol: °

However I don't want to use the htmltext, since I am building my own
table display from the data. Is there a way to translate a symbol to
it's html entity? I suppose I could just use a lookup table of the

Hi All,

I have a field of data that I want to format into a web page. The data

However I don't want to use the htmltext, since I am building my own

it's html entity? I suppose I could just use a lookup table of the

You could cut/paste the list from the rev docs :-)


I'm not suggesting this directly, but you could do something based on ...

repeat with i = 1 to the number of chars in fld "Field"
 if "&" is in the htmltext of char i of fld "Field" then
   put char i of fld "Field" && the htmltext of char i of fld "Field" & 
cr after msg

 end if
end repeat


(or fill a field with numtochar(i) for all i, and build a table that way)
put empty into fld "Field"
repeat with i =1  to 255
  put numtochar(i) after fld "Field"
end repeat
repeat with i = 1 to the number of chars in fld "Field"
 if "&" is in the htmltext of char i of fld "Field" then
   put  i && the htmltext of char i of fld "Field" & cr after msg
 end if
end repeat

OK... When the window is maximized or restored, the target width/height is
provided in the newWidth/newHeight params, and only the newWidth param seems
to be something to "lock" onto. Secondly, maximizing on MacOS X leaves a 10
pixel margin on all sides and doesn't go out the full distance (i.e. on a
1280x1024 screen, the width of the window after resizing is 1260, not 1280).

So this code will detect Maximize/Restore, or will show the current stack
rect if you're not maximizing/restoring (works for Mac/Windows - haven't
tested on Linux):

on resizeStack newW,newH,oldW,oldH
  if the platform is "MacOS" then put 20 into tAdjust
  else put 0 into tAdjust
  if oldW = (item 3 of the windowBoundingRect)-tAdjust then
put "Maximized"
  else
if newW = (item 3 of the windowBoundingRect)-tAdjust then
  put "Restored"
else
  put oldW,oldH,newW,newH
end if
  end if
end resizeStack

Let me know if this works for you guys...

Whoops! Sorry - typo! "oldW" and "newW" should be reversed:

on resizeStack newW,newH,oldW,oldH
  if the platform is "MacOS" then put 20 into tAdjust
  else put 0 into tAdjust
  if newW = (item 3 of the windowBoundingRect)-tAdjust then
put "Maximized"
  else
if oldW = (item 3 of the windowBoundingRect)-tAdjust then
  put "Restored"
else
  put oldW,oldH,newW,newH
end if
  end if
end resizeStack

Thanks Alex, this looks like the way to go. I hadn't realised I could
get the htmlText of a single character.

Cheers,

Re: Read file with accented characters ?

Thanks for your suggestion.
I tried this function but results are not enough accurate.

It's the same problem with all the functions I have already tried : I'm not
able to recognize a MS Word document saved in "simple text" format from a
BBEdit file saved in Mac format... And I need to recognize them because
BBEdit files need to be translated with the built-in IsoToMac function.

Any ideas ?


I think this is a different problem than detecting line endings. On 
Macs, you can check the creator and type of the files to see if they 
were created by MS Word or BBEdit. On Windows, you can check for the 
".doc" extension to see if it is a Word file.


To get the Mac file creator and type, use "the detailed files" (see 
"files" in the dictionary). The last item of the detailed files is the 
Mac creator and type codes.

Obviously, $HOME, $USER and $USERNAME are useful since they give the 
user's name. How much of the rest could be calculated under different 
Linux distros is hard (for me) to say.

Yes, but in order to be able to automate sudo through Rev, you need to 
able to find sudo in the file system in the first place. Also, to be 
able to achieve certain things through sudo, the automation routine 
would have to be in possession of the root password - hardly practical.


Is that right in your opinion, or have I missed the point here?

Does anyone really think an image external that does the stuff

All I can say is that I will need these features very soon in an

with Chipp and am excited about the things he is working on.
