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
