Tim, it you looks like you created the program that I used and mentioned in the original post of this thread above. You can find your original post in this old thread: https://www.omnimaga.org/hp-calculator-p...hp-prime)/ With your DIMGROB creator program, how would you then have the output (with relevant pixels coloured your transparency colour in the program) appear transparent?

Also, what is the colour method that your program outputs? This format: #8000800080008000:64h - 64 bit Hex? Would that make it 32768,32768,32768,32768 for R,G,B,A. I'm just trying to understand that. Should the calculator see that as transparent?
