There are two main types of tools used for digital illustration: bitmapped (also known as "raster") and vector applications. Bitmap applications are commonly called "painting" programs, such as Adobe Photoshop, while vector applications, such as ...
Performing a merge in this manner preserves all of the pixel data on both layers to more easily enable future changes in the new merged image. Slicing of images A more recent tool in digital image editing software is the image slicer.
[1] A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program.
