pl_AGGPas
it's Object Pascal native port of AGG C++ library for CodeTyphon Studio.
Anti-Grain Geometry (AGG) is a high-quality 2D rendering library.
AGG (and AggPas too) doesn't depend on any graphic API or technology.
Basically, you can think of AGG as of a rendering engine that produces pixel images in memory from some vectorial data.
It features anti-aliasing and sub-pixel resolution. It is not a graphics library, per se, but rather a framework to build a graphics library upon.
The library is operating system independent and renders to an abstract memory object.
It comes with examples interfaced to the X Window System, Microsoft Windows, Mac OS X, AmigaOS, BeOS, SDL.
The examples also include an SVG viewer.
The ideas and the philosophy of AGG are:
- Anti-Aliasing.
- Subpixel Accuracy.
- The highest possible quality.
- High performance.
- Platform independence and compatibility.
- Flexibility and extensibility.
- Lightweight design.
- Reliability and stability (including numerical stability).
Below there are some key features (but not all of them):
- Rendering of arbitrary polygons with Anti-Aliasing and Subpixel Accuracy.
- Gradients and Gouraud Shading.
- Fast filtered image affine transformations, including many interpolation filters (bilinear, bicubic, spline16, spline36, sinc, Blackman).
- Strokes with different types of line joins and line caps.
- Dashed line generator.
- Markers, such as arrowheads/arrowtails.
- Fast vectorial polygon clipping to a rectangle.
- Low-level clipping to multiple rectangular regions.
- Alpha-Masking.
- A new, fast Anti-Alias line algorithm.
- Using arbitrary images as line patterns.
- Rendering in separate color channels.
- Perspective and bilinear transformations of vector and image data.
- Boolean polygon operations (and, or, xor, sub) based on Alan Murta's
