| abstract | - A bitmap graphics editor is a computer program that allows users to paint and edit pictures interactively on the computer screen and save them in one of many popular "bitmap" or "raster" formats such as JPEG, PNG, GIF and TIFF. Usually an image viewer is preferred over a bitmap graphics editor for viewing images. Some of the features common to many bitmap graphics editors are:
* Select a region for editing.
* Draw lines with brushes of different color, size, shape and pressure
* Fill in a region with a single color, gradient of colors, or a texture.
* Select a color using different color models (e.g. RGB, HSV), or by using a color dropper.
* Add typed letters in different font styles.
* Remove scratches, dirt, wrinkles, and imperfections on photo portraits.
* Composite editing by using layers.
* Edit and convert between various color models.
* Apply various filters for effects like sharpening and blurring.
* Convert between various image formats
