A bitmap is a rectangular array of data corresponding to the pixels of a display device. The area of graphics programming associated with bitmaps is sometimes called raster graphics (named after the scan lines of early video displays) in contrast to the vector graphics of lines and curves.
The article Bitmap Basics in SkiaSharp described some of the fundamentals of loading and displaying bitmaps. These articles expand on the concepts in that introductory article:
Learn how to display SkiaSharp bitmaps in their native pixel sizes or expanded to fill to rectangles while preserving the aspect ratio.
Learn how to create SkiaSharp bitmaps and then draw on these bitmaps by creating a canvas using the bitmap as a drawing surface.
Learn how to use SkiaSharp to design a user interface for interactively describing a cropping rectangle.
Discover the specialized nine-patch and lattice options for rendering bitmaps.
Save bitmaps in the user's photo library.
Discover the various techniques for accessing and modifying the pixel bits of SkiaSharp bitmaps.
Learn how to perform bitmap animation by sequentially displaying different bitmaps, and rendering animated GIF bitmaps.
