Hi, I need to write a image editor as part of my project.

I think GR32 may be what I need but don't know how I should get
started (never really used it, and the documentation I could not see
it give a basic overview of what control is suited best to what need).

TPaintBox32
TImage32
TImageView32 (Use this one?)
Also there is TBitmapLayer class?

I need to implement for example:

Load/Save (bitmap, png etc)
Layers
Effects (Brightness, Contrast, HUE etc)
Paint on the layers (opacity, different brushes, erase tool)
Select tools

But don't know where to begin, which control/class to use etc?

Thanks

Hi
Sounds like you need 'BGRABitmap' package available in 'OPM'.
