  2. 9-slice scaling - Wikipedia

    en.wikipedia.org/wiki/9-slice_scaling

    9-slice scaling (also known as Scale 9 grid, 9-slicing or 9-patch) is a 2D image resizing technique to proportionally scale an image by splitting it in a grid of nine parts. [ 1 ] The key idea is to prevent image scaling distortion by protecting the pixels defined in 4 parts (corners) of the image and scaling or repeating the pixels in the ...

    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.

    A DZC is a collection of some number of DZIs linked and referenced by a DZC file (with either a .dzc or .xml extension). At a high level, a collection is a number of image thumbnails whose location is kept track of by the .dzc/.xml file, when zooming into an image, it accesses greater resolutions tiles.

  6. Image scaling - Wikipedia

    en.wikipedia.org/wiki/Image_scaling

    When scaling a vector graphic image, the graphic primitives that make up the image can be scaled using geometric transformations with no loss of image quality. When scaling a raster graphics image, a new image with a higher or lower number of pixels must be generated. In the case of decreasing the pixel number (scaling down), this usually ...

    File extension .pgf and the TLA PGF are also used for unrelated purposes: Adobe Illustrator used a Progressive Graphics Format before Encapsulated PostScript. PGF/TikZ uses a Portable Graphics Format in SourceForge project PGF. XnView and Konvertor associate file extension .pgf with Portfolio Graphics.

    Maxim Stepin's hq2x, hq3x, and hq4x are for scale factors of 2:1, 3:1, and 4:1 respectively. Each work by comparing the color value of each pixel to those of its eight immediate neighbors, marking the neighbors as close or distant, and using a pre-generated lookup table to find the proper proportion of input pixels' values for each of the 4, 9 ...

  9. Image file format - Wikipedia

    en.wikipedia.org/wiki/Image_file_format

    An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF.Most formats up until 2022 were for storing 2D images, not 3D ones.
