Does anyone know of a problem where glRasterPos2d causes a crash? If the raster position is invalid then glRasterPos2d returns without crashing but if I adjust the modelview and projection matricies to what appear to me to be valid values then calling glRasterPos2d causes the error message listed below. I searched the archives and found the following workaround, instead of calling glRasterPos2d I call: glBitmap(0,0,0,0,posX,posY,null); glDrawPixels(imageWidth,imageHeight,gl.GL_RGBA,gl.GL_UNSIGNED_BYTE,image); glBitmap(0,0,0,0,-posX,-posY,null); // I need to draw several images so restore to bottom left for next This does exactly what I want, which is to position to the screen coordinates posX,posY, but it has one disadvantage which is that when the window is resized the position is no longer relative to the bottom left of the screen and my images is drawn in the wrong place. Is there a way to reset the position to the bottom left of the screen? Also if I can get glRasterPos2d working is there a way to position in screen coordinates as the workaround does? Although I am using Java with a thin OpenGL wrapper (Jogl) I get a similar crash with C# / CSGL so this suggests to me that it is not the OpenGL wrapper causing the problem? I would appreciate any help.
