RGB Red Green Blue – Screen displays are based on mixing red, green and blue light for generating colors. There are two main Modes used for defining colored images. The Mode defines the base colors which are used to generate all the colors in the color range by mixing them together. The color range is depending on the Mode of the image.
#CONVERT RASTER TO VECTOR IN PAINT SHOP PRO PDF#
Examples are importing a pdf file in Photoshop and also before printing vectors are rasterized.Įach pixel can contain one color. A method to counter this effect is called anti-aliasing. Especially sloped and curved lines tend to show a sawtooth pattern. One could see it as super imposing a grid on a vector object and then determining the color value. The process is which a vector file is converted to a bitmap is called rasterizing. JPEG only uses lossy-compression whereas TIFF rarely or never uses lossy-compression.
Each file format has it's own way to compress. These methods can be divided in two categories: lossy and non-lossy. There are several methods available for saving files, all using different ways of compression in order to limit the file size. Most used extension for bitmap images are:Īpplications for creating and editing bitmap or raster images are: Photoshop primarily works with raster images and has limited support for vector graphics. Raster images can be edited with software such as Photoshop, GIMP, Paint and Paint Shop Pro. This makes it impossible to scale a raster image without loss of quality. The raster becomes apparent and the image will no longer have sufficient detail for smooth shapes. The main disadvantages becomes apparent when scaling or zooming-in to a part of the image. Because raster images are based on pixels they have certain disadvantages. Often pixel images are referred to as raster images because an image consists of a raster or grid of pixels. Generally speaking, they consist of pixels (squares) with a certain color value.
Digital photos are raster images, for example. Pixel or raster images are the most commonly used type of images.
