after some tests, there is still a colorspace problem when using the set
message.
I think there is no reason the image initialization in the set message
should be different than in the constructor.
Using this declaration of the setMess function solve this problem here:
---
void pix_noise :: SETMess(int xsize, int ysize)
{
if ((xsize < 1) || (ysize < 1)) return;
m_pixBlock.image.clear();
m_pixBlock.image.xsize = (int)xsize;
m_pixBlock.image.ysize = (int)ysize;
m_pixBlock.image.setCsizeByFormat(GL_RGBA);
m_pixBlock.image.allocate();
generateNoise();
}
Best,

ok that's clear.
it works now.
this is the syntax used in [pix_set] maybe you should have a look
there as well.
thanks

i had a look and found the following:
- - the code was always buggy :-)
- - it used fixed color offsets within pixels (e.g. "3" for "blue"),
which
is simply wrong on OSX. Gem has special constants "chRed",... for
platform independent color offsets.
- - i also changed the color-type from GL_RGBA to GL_RGBA_GEM, which
will
actually do the same (GL_RGBA on w32&linux and GEM_BGRA_EXT on osx) but
with less confusion :-)
