OK, so I have some C++ flavored OpenGL code to draw a line to a renderbuffer in XCode 3.2.2. I then use glReadPixels to get the pixels to pass into REALBuildPictureFromBuffer. Here's where things get odd;
<a bunch of openGL code goes here, and I can post it all if need be, but bear with me…> //Allocating my buffer. unsigned char myBuf[imageWidth * imageHeight * 3]; //Populating my buffer. glReadPixels( 0, 0, imageWidth, imageHeight, GL_RGB, GL_UNSIGNED_BYTE, &myBuf); //Cleaning up after myself. glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, 0); glDeleteRenderbuffersEXT(1, &renderbuffer); //Maximum strangeness happens here; return REALBuildPictureFromBuffer(imageWidth, imageHeight, kRBPixelRGB24, myBuf, imageWidth * 3); Here's the issue. When imageWidth = imageHeight, it works perfectly. When imageWidth <> imageHeight, my test app which calls my plugin method crashes almost instantly. Now it's quite possible that I'm overlooking something fundamental, as I've only just begun my XCode odyssey and there's a TON I don't know. Still, this has me scratching my head. Why would it work as expected in just one, limited case? _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives: <http://support.realsoftware.com/listarchives/lists.html>
