An image size can be changed in several ways. One of the simpler ways of increasing image size is nearest-neighbor interpolation, replacing every pixel with the nearest pixel in the output; for upscaling this means multiple pixels of the same color will be present. This can preserve sharp details in pixel art, but also introduce jaggedness in previously … Webis a highly efficient method for value preserving downsampling. This approach selects every nth data point from the input data array, where n is the ratio of the input array length (N) to the desired output array length (nout). The algorithm has a time complexity of O(nout) and a memory complexity of O(1). Notably, it is the only algorithm

WebMay 7, 2013 · Google's way (using inSampleSize) uses less memory during decoding, and is faster. However, it causes some graphical artifacts sometimes and it only supports downsampling to the power of 2, so the result bitmap might take more than what you wanted (for example size of x1/4 instead of x1/7) .
