Raster graphics editor

From Wikipedia, the free encyclopedia

A raster 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 raster graphics editor for viewing images.

Some editors specialize in the editing of photo-realistic images such as the popular Adobe Photoshop, while others are more geared to artist-created illustrations.

[edit] Some features common to many raster graphics editors are:

• Select a region for editing.
• Draw lines with brushes of different colour, size, shape and pressure
• Fill in a region with a single colour, gradient of colours, or a texture.
• Select a colour using different colour models (e.g. RGB, HSV), or by using a colour dropper.
• Add typed letters in different font styles.
• Remove scratches, dirt, wrinkles, and imperfections from photo images.
• Composite editing using layers.
• Edit and convert between various colour models.
• Apply various filters for effects like sharpening and blurring.
• Convert between various image formats.
