Hi Ken,
the problem was solved by checking bitsPerPixel and changed the pixel format
to GL_RGB, GL_UNSIGNED_BYTE
but, if the best combination of format / type is GL_BGRA,
GL_UNSIGNED_INT_8_8_8_8_REV so does it means we need to convert RGB / RGBA
to BGRA?
sorry for posting in cocoa list

Hi,
Please go down to the phrase "apps are rather fond of hardcoding bitmap
formats" in the AppKit release notes.

Does your image have alpha?
format is bm

Exactly what does not work?

texture is corrupted with artifact on the screen and sometimes
gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, [image pixelsWide], [image
pixelsHigh], GL_RGBA, GL_UNSIGNED_INT_8_8_8_8_REV, [image bitmapDa
Exactly what does not work?
The loading? Or the opengl command?
If the latter I suspect that your file is not in the needed format.
Does your image have alpha?

NSData *data = [NSData dataWithContentsOfFile: filename];
NSBitmapImageRep *image = [[NSBitmapImageRep alloc] initWithData: data];
as opposed to:
// works fine
NSImage *source = [[NSImage alloc] initWithContentsOfFile: filename];
NSSize size = [source size];
[source lockFocus];
