It is easier to rasterize a vector image than to vectorize a raster image; how to go about vectorizing a raster image is the focus of much research in the field of computer vision. Vector images can be modified more easily because they contain descriptions of the shapes for easy rearrangement.
Chasys Draw IES (previously called Chasys Draw Artist) is a suite of applications including a layer-based raster graphics editor with adjustment layers, linked layers, timeline and frame-based animation, icon editing, image stacking and comprehensive plug-in support (Chasys Draw IES Artist), a fast multi-threaded image file converter (Chasys Draw IES Converter) and a fast image viewer (Chasys ...
Darktable, a raw photo post-processing application GIMP, a feature-rich general-purpose raster graphics editor. A raster graphics editor (also called bitmap graphics editor) is a computer program that allows users to create and edit images interactively on the computer screen and save them in one of many raster graphics file formats (also known as bitmap images) such as JPEG, PNG, and GIF.
Good Q. An example of a (vector) PDF map ready for conversion to SVG is this. PDFs can contain practically any type of information, the most common ones being text, raster images (ordinary images like bitmaps) and vector graphics. The vector information has to be coded into the PDF as such.
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. Some programs are more ...
Vectorization first creates a resolution-independent vector representation of the graphic to be scaled. Then the resolution-independent version is rendered as a raster image at the desired resolution. This technique is used by Adobe Illustrator Live Trace, Inkscape, and several recent papers. [6]
In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more.This is accomplished by doing a convolution between the kernel and an image.
GIMP is a programme for raster image processing, so it is not meant to be used for any kind of schematics. It does not support SVG and everything has be drawn from scratch. Anyway it is multi-platform and several people used it on Commons to draw circuits. It could be useful for some post-processing, but the output will not be in SVG.
