Hello together,
the next upcoming version of JavaCPC will have a great new feature: JavaCPC Paint!
This is a tool to paint directly into CPC-screen memory.
You can also convert BMP,PNG,GIF and JPG files into CPC screens, too.
(Overscan and other extra modes are not supported)
You can also paint into this tool, add texts, cut out shapes, paste shapes and much more.
The screens can be saved then to DSK (when PAINT binary is running) or to your PC.
The screens are OCP-Art-Studio compatible, inclusive a .PAL file containing screen's palette & screen-mode.
The tool is not the "non-plus-ultra" but it's a great feature for JavaCPC, I think.
Here's a preview-screenshot:
