[SOLVED] PNG image format in LFM

[Dmitriy]

Have a nice day!
Where can I read the description of Picture.Data format in LFM-file?
For example, for PNG image.

LCLVersion = '2.0.8.0'
object Image1: TImage
Picture.Data = {1754506F727461.......}

Best regards, Dmitriy.

Hello Dmitriy,
Welcome to the forum.

Why do you need to read it directly from the .LFM file?

If you really need to do it, you should load it into memory and you can get the data. It is a bit hard, but you can learn it here:

You might also look to the code for TPicture or TPNGImage (or however it's called) to see how they implement it.

Or somewhere in the source of Lazarus itself, dauntig as the task may seem.

It's probably just the image uuencoded and prefixed by some record that lists e.g. coordinates and maybe format).

I'm making small Lazarus online for school.
Thank you for the link! I've found interesting information there.
