Graphics, bitmap

images are laid out in pixels , much like dots of paint on a canvas. As such, bitmap objects are not independent entities, which can be singled out for manipulation, but patterned series of dots. To enlarge (or reduce) bitmap images, the number of pixels is increased (decreased), often giving the resulting image a jagged appearance. (See anti-aliasing .) Scanners produce bitmap images (.TIF), as does Windows' PaintBrush (.BMP, .PCX): Bitmaps are one of the most commonly compatible types of image formats.
File formats include: IMB, DIB, GIF, MTX, PCX, TIF, TGA, BMP, WPG, JPG, CUR, CO. (See Image File Formats) PaintShop Pro can be used to convert to/from various formats. Its help menu provides full definitions for all graphics file formats. PaintShop Pro maintains the aspect ratio of pictures when sizing, thus can reduce sizing distortion.
