IndexOutOfBoundsException drawing pixels in byte array on Intel Macs

I am having a problem on the new Intel Macs, where I get the following error:

Exception in thread “AWT-EventQueue-0” java.lang.IndexOutOfBoundsException: Required 4194304 remaining bytes in buffer, only had 4161536
at com.sun.gluegen.runtime.BufferFactory.rangeCheckBytes(BufferFactory.java:274)
at com.sun.opengl.impl.GLImpl.glDrawPixels(GLImpl.java:3648)
…

at gl.glDrawPixels(width, height, GL.GL_RGBA, GL.GL_UNSIGNED_BYTE, ByteBuffer.wrap(src));
where src is a byte array of size 1024x1024x4; This only happens on the new Intel Macs. I’ve tried to rewind the wrapped byte buffer but that changes nothing. I’m using the latest jogl jars and universal jar for macs. The dump of the capabilities of the GLCnavas and the offscreen pbuffer canvas are below:

Anybody know whats happening and how I can fix it. It seems that the size of the byteBuffer is not beiong seen correctly.

Could you add some printlns to your code before you call glDrawPixels to print remaining(), etc. on the byte buffer? It looks to me like your image is sized incorrectly by some 8 pixels.

#3

The draw statement is:

gl.glDrawPixels(width, height, GL.GL_RGBA, GL.GL_UNSIGNED_BYTE, ByteBuffer.wrap(src));

where src is a byte array of size 1024x1024x4. The ByteBuffer that wraps src does not exist before the draw pixels statement or after. I tried to create it before using:
ByteBuffer texture = ByteBuffer.wrap(src);
texture.rewind();
gl.glDrawPixels(width, height, GL.GL_RGBA, GL.GL_UNSIGNED_BYTE, texture);

but the same error occured.

#4

Well something weird is going on because JOGL is correctly computing the number of bytes which need to be present in the Buffer passed to glDrawPixels and it seems that there are too few bytes in the Buffer being passed in to it. I would again suggest you print out the remaining() bytes on the Buffer before the call to glDrawPixels and see whether it matches what JOGL is reporting in its error message. If they match, something is wrong with your image data.

#5

Ok. I’m checking, cause something strange is happening between the code executed on linux and Intel Macs. I’m trying to get the same conditions between the two with GLCanvas size and eveything to make sure its not my code.
