A key difference with tool blending versus layer blending is that the results of tool blends are generally not able to be adjusted after the stroke is made, with the exception of stepping backward with the application's Undo command; layer blends may be adjusted with opacity or even switched, as they are applied dynamically between layers.
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite .
Each layer may bear individual settings, such as opacity, blending modes, dynamic filters, and potentially hundreds of other properties. The top layer (the bird) is partially transparent, so the background clearly can be seen through its wing.
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] Scalable Vector Graphics are well suited to simple geometric images, while photographs do not fare well with vectorization due to their complexity.

The PDF specifications say to use linear encodings both for blending and the subsequent compositing. That recent W3C spec says nothing, but its author has stated that (for Canvas and SVG at least), blending is to be performed in device space. That Photoshop has a "rarely used" mode for setting the gamma used for blending.
It supports multi-page documents, and includes an integrated presentation mode. ConceptDraw PRO supports imports and exports several formats, including Microsoft Visio and Microsoft PowerPoint. Corel Designer (originally Micrografx Designer) is one of the earliest vector-based graphics editors for the Microsoft Windows platform. The product is ...
A "linear" blend would match physical light blending and has been the standard in game engines for a long time. [16] On the web, however, it has long been neglected for both color gradients and image scaling. [17] Such a blend still has a subtle difference from one done in a perceptually-uniform color space.
