When you think of graphic editors, the first name that comes to mind is Photoshop (or GIMP, if you are a Linux user). However, both Photoshop and GIMP are only great for editing photos and creating raster images. Raster images, such as PNG or JPG, are fine in many cases, but very often you will need a more scalable format. RasterVect: Purpose RasterVect Software has released RasterVect, the professional raster to vector conversion program (vectorizer). The purpose of RasterVect is to quickly convert uneditable scanned paper drawings into accurate vector files for editing (as a CAD drawing) in any CAD program. Embedding and optional tracing of raster graphics is also supported, enabling the editor to create vector graphics from photos and other raster sources. Created shapes can be further manipulated with transformations, such as moving, rotating, scaling and skewing. Right-click the raster layer, click Properties, then click the Functions tab. This allows you to modify the raster layer's function chain. This allows you to modify the raster layer's function chain. Select the layer in the Image Analysis window and click the Add Function button.

Raster Image Editors
& sample pseudo-3D objects
Raster (pixel-based) image editing programs include Photoshop, Painter, Photo-PAINT, and others that edit graphics composed of pixels. In contrast, drawing or CAD programs like Illustrator, Freehand, Flash, CorelDRAW, and AutoCAD produce vector, or shape-based, graphics. Any scanned image is made up of pixels, and is therefore a raster image. Some raster graphic formats are JPEG, GIF, and TIFF, and others.
When working with 3D software applications, models are stored as vector (geometric) data, but rendering generates a raster image (made of pixels) for a final result. Since rendered images are raster images, it is sometimes feasible to use a raster image editor and/or a plug-in effects filter such as Kai's Power Tools to create graphics that look like they were rendered in a 3D program. I refer to these graphics as pseudo-3D.

A raster graphics editor is a computer program that allows users to create and edit images interactively on the computer screen and save them in one of many raster graphicsfile formats (also known as bitmap images) such as JPEG, PNG, GIF.
Comparison to vector graphic editors[edit]
Vector graphics editors are often contrasted with raster graphics editors, yet their capabilities complement each other. The technical difference between vector and raster editors stem from the difference between vector and raster images. Vector graphics are created mathematically, using geometricformulas. Each element is created and manipulated numerically; essentially using Cartesian coordinates for the placement of key points, and then a mathematical algorithm to connect the dots and define the colors.

Raster images include digital photos. A raster image is made up of rows and columns of dots, called pixels, and is generally more photo-realistic. This is the standard form for digital cameras; whether it be a .raw file or .jpg file, the concept is the same. The image is represented pixel by pixel, like a microscopic jigsaw puzzle.
Vector editors tend to be better suited for graphic design, page layout, typography, logos, sharp-edged artistic illustrations, e.g., cartoons, clip art, complex geometric patterns, technical illustrations, diagramming and flowcharting.
Advanced raster editors, like GIMP and Adobe Photoshop, use vector methods (mathematics) for general layout and elements such as text, but are equipped to deal with raster images down to the pixel and often have special capabilities in doing so, such as brightness/contrast, and even adding 'lighting' to a raster image or photograph.
Common features[edit]
- Select a region for editing
- Draw lines with simulated brushes of different color, size, shape and pressure
- Fill 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
- Edit and convert between various color models.
- Add typed letters in various font styles
- Remove imperfections from photo images
- Composite editing using layers
- Apply filters for effects including sharpening and blurring
- Convert between various image file formats
