Keeping graphic objects in programs

This can be done on your computer. Simply create them, and incorporate them into your application. Or if you generate them on your calculator, you can save the image on the screen using AFiles("filename.png"):=G0 (G0 through G9 are the system's graphic objects, with G0 being the current screen.) The AFiles() command really only makes sense within a custom application (i.e. an app you create based on one of the existing apps).

Dear Mr. Han,
How can I make such an app? What I've noticed about custom apps is that there are files placed in a directory, and the extension is ".hpappdir". This directory must then be copied into the CK during installation. Do you create such a directory on the PC / MAC, and is it compatible with the Prime? And how do you load those .PNG files into your program? This is all very confusing to me. I would like to receive a response from you. Sincerely, Karel.
