About
LazRGBGraphics is run-time package for fast in memory image processing and pixel manipulations (like scan line). The main advantage is direct memory access to bitmap pixels with keeping ability to draw bitmap onto canvas without any widgetset time consuming memory format converting.
The main class is TRGB32Bitmap which is anolog to TBitmap.
TRGB32Bitmap features:
- load from file, save to file
- creating from TBitmap
- drawing and stretchdrawing to TCanvas
- rotating, stretching
- inverting colors
- drawing primitives via canvas (TRGB32Canvas) with emphasis on accuracy
- per pixel manipulation via GetPixelPtr
The download contains the package and simple example application.
This package was designed for cross-platform usage.
