1. Does anyone know or is it in specification (or referential MIDP implementation) how much heap I need for loading an png palette based image? For example with image 200x200 pixels (= 40000 bytes unpacked) packed to 10000 bytes (= .png size) do I need 10000 or 40000 bytes from heap? Yes, it can depend on MIDP implementation (I'm using 7650).
2. What are the maximum dimensions of an image for 7210 and other devices?
