   Making an image that was incorrectly saved as JPEG fit for saving as PNG; Suppose you have a map for an island that was inadvertently saved as JPEG. Looks OK, if a bit fuzzy. 1. In your bitmap graphics editor, set your fuzzy selection ("magic wand") tool so that it only will select pixels of exactly the same color. (Here: Threshold = 0) 2.

   Format conversion: convert an image from one format to another (e.g. PNG to JPEG). Transform: resize, rotate, crop, flip or trim an image. (Applies these without generation loss on JPEG files, where possible.) Transparency: render portions of an image invisible. Draw: add shapes or text to an image.

   The PNG file format supports 8-bit (256 colors) paletted images (with optional transparency for all palette colors) and 24-bit truecolor (16 million colors) or 48-bit truecolor with and without alpha channel – while GIF supports only 8-bit palettes with a single transparent color.

   To the right is an example of a file saved as JPEG when it should have been saved as PNG. JPEG uses lossy data compression meant for photographs. Compressing drawings or diagrams with JPEG results in an image of poor quality, because the human eye can spot the compression artifacts around the edges.

   optimisation of the Huffman coding layer of a JPEG file to increase compression, conversion between progressive and sequential JPEG formats, conversion between Huffman and arithmetic coding in the entropy coding layer. [5] [6] [7] These transformations are each completely lossless and reversible. The transformations on the image data comprise:
