IEBitmap->Canvas
or
IEBitmap->IECanvas

What is better to use and why?

Hi

Canvas is a standard VCL TCanvas.

TIECanvas is a GDI+ based canvas:

Use TIECanvas whenever you can because it supports newer features, like anti-aliasing and advanced text drawing.

I began to change TCanvas to TIECanvas in the program and ran into a problem that they are not fully compatible.

For example TIECanvas does not work with
PolyBezier
Pixels
CopyMode
FloodFill
etc.

Could this be fixed?

GDI+ does not support all the functionality of TCanvas, such as PolyBezier and CopyMode.

For Pixels, use TIEBitmap.Pixels[]

For FloodFill, you can use TImageEnProc.CastColor:
