Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem.According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts.
Scalable Vector Graphics are well suited to simple geometric images, while photographs do not fare well with vectorization due to their complexity. Note that the special characteristics of vectors allow for greater resolution example images. The other algorithms are standardized to a resolution of 160x160 and 218x80 pixels respectively.
The following examples use the "thumb" or "frameless" options to set an image to the default size, with "upright" to scale the image larger or smaller than the default size. When using these options, a small image will never be scaled larger than its original size.
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 ...
(E.g. 100px) Scale the image to make it the specified number of pixels in width, and scale the height to retain the original aspect ratio. xHeightpx (E.g., x150px) Scale the image to make it the specified number of pixels in height, and scale the width to retain the original aspect ratio.
