Well, I do not have much time now, because I'm working on LazFreeType.

Can you give some help ?

We can start to think about layers. For example, which file format should PazPaint use to store layered bitmaps ?

as much as i want to help im not knowledgeable enough about graphics programming and im a noob in programming too cannot do OOP  %)

http://en.wikipedia.org/wiki/OpenRaster ?

that looks good thanks for suggesting

Why not. I've already thought about it, I will look again if I find it satisfactory.

I've looked at OpenRaster again, and well the problem is that :
- it must be compressed with zip format (so a zip compressor/decompressor is needed)
- it uses PNG, which is not reliable on FreePascal

Have you a way to solve this ?

Or another format to propose ?

It is part of standard FPC library.

That's bad, but I think in that case fixing PNG support would be
a worthy goal on its own, wouldn't it?

Post a bug report about PNG problems?

There's GIMP's XCF, but AFAIK GIMP developers themselves
say that OpenRaster is preferable as an interchange format.

Where ? I only know about zstream, which allows to compress but not in the zip format.

Yes. Some people have already posted about errors.

There is also PSP and PSD formats.

In fact, any of these format contains features that I do not plan to implement, and do not contains features that I have implemented (more blend modes). Maybe there are workarounds for it with OpenRaster by combining filters. Otherwise I should reduce available blend modes.

So I guess I will anyway make a reader/writer with a format that correspond to LazPaint data. But I would like to have maximum interoperability, so the best would be to handle OpenRaster, PSP and PSD too.
