In Small Basic, these files can be loaded with following operations. There are a lot of formats for raster graphics.
Paint is one of most popular program to create raster graphics (or bitmap). The raster image will be cropped by the clip of the raster image. Raster Graphics Raster graphics is about digital pictures painted with colored pixels (dots). If there was no selected images, then the command processes all visible images placed in non-locked layers that have the clip. Select raster to be processed (visible and placed in non-locked layers). To crop the raster by clip, the clip of the raster image should be predefined ( Modify → Clip → New… command).ġ. Parts of an image outside the specified area are cropped. Specify two opposite corners for the rectangular area in the raster. If the raster has no frame, then the result of Auto crop by frame is similar to the Crop → Auto.Ĭropping can reduce an image size to a specified rectangular area size.Ģ. If the image has deformations, use the Deskew command for correct CROPBYFRAME behavior. If the raster has a frame, then the command automatically changes the size of raster by the frame. If there was no selected images, then the command processes all visible images placed in non-locked layers. Select raster to be processed on the screen. For example you can crop pack of images by placing them on top of each other.Īutomatic crop trims the "empty" image field to the smallest possible rectangle that includes all raster data.ġ. These operations apply to multiple images at once. Also, raster can be cropped automatically using procedure that determines empty image fields and crops them. This area can be determined by set clip of image or rectangle. Examples of images that are well suited for the vector format include logos and type.The size of raster image can be reduced to determined area by using Crop operations. Vector formats, on the other hand, are better for images that consist of a few areas of solid color. Today however, all major browsers support the SVG (Scalable Vector Graphics) format.īitmap formats are best for images that need to have a wide range of color gradations, such as most photographs. The Scalable Vector Graphics (SVG) format comes in a distant fourth due to a legacy of poor support for vector graphics in early browsers.
The three most popular image formats used on the Web (PNG, JPEG, and GIF) are bitmap formats. When a vector image is scaled up, the image is redrawn using the mathematical formula, so the resulting image is just as smooth as the original. There are ways of making these jagged edges less noticeable but this often results in making the image blurry as well. This is most noticeable in the edges of the image. When a bitmap image is scaled up you begin to see the individual pixels that make up the image. Vector images are also more scalable than bitmap images.
Sample vector graphic from FCIT’s collection of Math illustrations on the ClipArt ETC website. A vector image just has to store the mathematical formulas that make up the image, which take up less space. That’s because a bitmap image has to store color information for each individual pixel that forms the image.
Vector images tend to be smaller than bitmap images. Vector images have some important advantages over bitmap images. Vector images are edited by manipulating the lines and curves that make up the image using a program such as Adobe Illustrator. Unlike bitmaps, vector images are not based on pixel patterns, but instead use mathematical formulas to draw lines and curves that can be combined to create an image from geometric objects such as circles and polygons. Sample raster graphic from FCIT’s collection of robot illustrations on the TIM website. Bitmap graphics can be edited by erasing or changing the color of individual pixels using a program such as Adobe Photoshop. When you zoom in on a bitmap image you can see the individual pixels that make up that image. Each pixel is actually a very small square that is assigned a color, and then arranged in a pattern to form the image.
#Basic building blocks of raster graphics editor series
Bitmap (or raster) images are stored as a series of tiny dots called pixels.
