When I create an Image object from resource (a png file), does it internally convert it to a raw format (24-bit or device dependent format e.g. 555RGB) ? or does it convert it on the fly when drawing it ?
If it statically converts it to 24-bit raw format:
1) I can store the raw image on the resource since it is already being compressed by jar.
2) Draw it using drawRGB.
so there is no need to use png if I had custom palettized and raw image processing routines.
If it dynamically converts it to raw format, what is the performance consequences of this ? It must look up palette tables and convert it to device dependent format, that must be a little heavy process.
Thanks in advance.
