Welcome to the index of the tutorials for the library BGRABitmap. You can browse tutorials by number with the bar on the top, or by the following categories :
Install BGRABitmap and draw basic shapes
The images of TBGRABitmap have drawing functions using floating point coordinates or integer coordinates.
- Installing BGRABitmap (No. 1)
- Loading and displaying an image (No. 2)
- Drawing with the mouse (No. 3)
- Line styles (No. 6)
- Splines and Bézier curves (No. 7)
- Texte fonctions (No. 12)
- Integer coordinates and floating point coordinates (No. 13)
Textures and scanners
Pixels are a table in memory containing values in the format TBGRAPixel. We can at this level do various operations.
- Direct pixel access with Scanline (No. 4)
- Combining layers of pixels (No. 5)
- Generating textures (No. 8)
- Phong shading using textures (No. 9)
- Texture mapping (No. 10)
- Using scanners to combine transformations (No. 11)
Other drawing contexts
It is possible to have other contextes, in order to have other basic drawing functions.
- Standard Canvas (Canvas and CanvasOpacity properties) : avoid using it because of the slowness of conversions of bitmap data
- Canvas with features brought by BGRABitmap (CanvasBGRA property, Brush and Pen have an Opacity property)
- Drawing with a 2D canvas with affine transformations
- Real 3D rendering
- Using textures with 3D rendering
Auxiliary classes
More classes, to be created for use, are also available.
- TBGRATextEffect, in unit BGRATextFX, allows to prepare the drawing of text line, to add effects like contour and shadow.
- TBGRALayeredBitmap, in unit BGRALayers, allow to create a multi-layered bitmap. Units BGRAPaintNet and BGRAOpenRaster contain implementations to read and write in Paint.NET format (read only) and OpenRaster format (read and write).
- Units BGRAGradientScanner and BGRATransform contain scanners to do various effects.
- Unit BGRAGradients contain procedures to generate gradients and TPhongShading class for Phong shading.
- TBGRACompressableBitmap, in unit BGRACompressableBitmap, allow to store and compress images.
Other units contient low level functions, and you should not need to use them for a normal usage.
