Cesare,

can I have your permission to add your
opcodes to Csound in CVS under the LGPL?

If so, can you remind me of the link
again? And another favour: could you then
post the manual pages to Andres?

Victor

Of course.

http://www.cesaremarilungo.com/download/csound/imageOpcodes.tar.gz

I've added the LGPL and a brief syntax description to the source file. I 
will send the manual pages to Andreas in the next 24-48 hours.

By the way, could you please let me know if you'll succeed in compiling 
and using these opcodes on the XO laptop? I am still setting up a 
development and testing environment for it and I don't know if I'll be 
ready before next Monday.

Thanks in advance,

-c.

Hi,

The opcodes should compile for xo, but not the default install, as it
doesn't include FLTK AFAIK. I'm not sure if it includes the image
libraries you were using before, but if you want them to run easily on
the xo, using a small library rather than FLTK might be a good idea.

Cheers,
Andrés

I am using imlib for this reason. So they hopefully should.

BTW, I have investigated a bit more on FTLK and it seems it lacks image 
saving facility, which makes sense since it is a gui toolkit so images 
are just supposed to be displayed.

I am still looking for a more widespread library to accomplish this. 
Other suggestions?

I would also like to know which is the praxis for this kind of 
situations. Who is the maintainer for the MacOS X and Windows binary 
distributions of csound? Does he/she build them with statically linked libs?

I am willing to port these opcodes to any other available library (it's 
really really easy since I just need to load and save images to/from a 
RGBRGBRGB... array, and the code to load and save is isolated in two 
functions at the beginning of the source) but I can't test or build for 
other platforms other than gnu/Linux.

Victor, please download this newer version. I've just realized that in 
the previous version, in order to store and retrieve pixel values, I was 
using the same callback for both k-rate and a-rate. Now I rewrote two 
separate callbacks for a-rate that take the whole sample block in account.

http://www.cesaremarilungo.com/download/csound/imageOpcodes20071123.tar.gz

Since this my first go at a csound plugin, would you mind to quickly 
browse the source to see if there's something else I might have overlooked?

Thanks,

- c.

I am the OSX maintainer; Michael Gogins is the Windows maintainer.
Could you just clarify the dependencies? This will probably be crucial
for the XO.

Hi Victor,

I have made another version which can be built with SDL and SDL_image 
(which is the only option I've found on so far on the XO laptop) and 
should work on MacOS X and Windows too. Unfortunately 'imagesave' is not 
implemented on these platforms yet since SDL_image lacks saving ability 
too. This is still a temporary solution.

For gnu/Linux (except on the XO) the only dependency is Imlib and should 
be already installed on almost every distribution. Here 'imagesave' can 
be used.

The file:

http://www.cesaremarilungo.com/download/csound/imageOpcodes20071123sdl.tar.gz

For the XO you can try to build it with:

scons OLPC=1

Ciao,

-c.

To Victor and Michael,

what if I rewrite the opcodes to use libpng?

http://www.libpng.org/pub/png/libpng.html

This is available (and would allow loading and saving ) on every 
supported platform (and on the XO too).

Of course this would limit the file format to PNG, but it would make 
sense since PNG is an open format and it uses lossless compression (so 
you always keep all the data).

What do you think?

- c.

I like the idea of using libpng (and/or other common libraries like libjpeg)
since it works on ALL of Csound's supported platforms (including MacOS 9).
Imlib seems to have some other Linux dependencies and FLTK does not work on
OS 9.  SDL_image would also be OK but it just uses libpng and libjpeg
anyways.

Further, the license of Imlib seems to be GPL which means that a Csound
plugin using it would have to be GPL and any Csound system that such a
plugin is distributed with would have to be converted to GPL.  This is the
same reason we stopped distributing binaries of the Loris opcodes ...

Here it is:
