Image processing systems are used to work with and change images, and choosing the right systems can be tough. You may want to consider image processing systems that have vector abilities, because a lot of people use vector images and those abilities help with printing and using an image. There are many image file types, and the best image system for your purposes should be able to handle the formats you commonly use; a conversion feature also may be useful. If you work on many images at once, sequential editing capabilities allow you to perform one change to many images simultaneously. Pixel searching and editing can help you search an image for a specific pixel and also makes it easier to make small changes to an image.
If you use image processing systems for clients, or if the images are printed, then having a vector function may be useful. A vector is a type of image that can be printed at any size without loss of quality, because the image is stored as points and not pixels. Vector images also are easier to store, because they use less memory. Most vector functions work on two-dimensional (2D) images, but some also work on three-dimensional (3D) images, which may be useful if you edit 3D images.
There are many image file types, and they are used for different purposes. To use and export these images, image processing systems should be able to work with many formats, or at least the formats you commonly use. Being able to convert from an image from one format to another also may be useful, especially if you need the image for a particular purpose, but the present format does not work well for that purpose.
All image processing systems allow you to work on one image at a time, but some also include sequential editing. This may be useful if you are working on many images at once and all those images require the same change. For example, if you want to cut off 10 pixels from the right side of 20 different images, sequential editing allows you to do this once and have it affect all 20 images. Sequential editing is not as useful if you prefer working on one image at a time or if each image needs different changes.
Pixel searching and editing may be useful if you need to search for or edit very small pieces of an image. With a pixel-searching feature, you can find an exact pixel based on its position, color or other factors. If each pixel needs to be exact and correct, pixel editing allows you to change each pixel individually.
