Au sujet de
LazRGBGraphics est un paquet d'exécution pour un traitement d'image rapide en mémoire et de manipulations de pixels(comme le balayage de lignes). L'avantage principal est l'accès direct en mémoire au pixels du bitmap en gardant la capacité de dessiner sur le 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.
