image editing

Image editing is part of image processing. It deals with the manipulation and modification of graphics, photos and images. The goal of image processing is to improve image quality, increase contrast and image sharpness, reduce image noise, and compensate for image distortion and deformation. It is also about realistic image impressions of 2D graphics and 3D graphics. In addition, there is image retouching with the modification of color depths, hues and color saturations.

Image processing includes all graphic techniques with which vector and pixel graphics can be technically manipulated, such as scaling the display, transforming the size, display axes and perspective. In addition, there are techniques for improving image quality through aliasing and antialiasing, shading and rendering, gamma correction and alpha blending, changing colors and color depths, and creating sharpness and blur.

Image processing functions

Image processing functions

You can define materials and the reflective behavior of their surfaces, use fogging to make bodies appear transparent or in fog, use texture mapping to project textures onto body surfaces, use ray tracing and environment mapping to simulate the environment on arbitrarily shaped object surfaces, use specular highlights to create specular highlight effects or environment mapping to create specular reflection effects.

In addition to the effects and transformations mentioned above, you can copy graphic files and convert graphic file formats with the image editor. You can fade in texts and textures and compress image files with photos and graphics. Important tools of image processing are color models and color mixing.
