If the new version is too sharp, you can utilize the blur filter or tool to fix this, or use Colors > Levels to mess with the Alpha channel. Once it looks correct, save the image as a PNG. Then, to reduce file size, run it through a program like ImageMagick that supports 8-bit PNGs with alpha transparency, in order to remove any unnecessary ...
Image Analyzer - Amongst other things, allows for lossy compression of PNG files. (Often, however, merely posterizing the image at a level that does not produce color banding results in smaller files of the same or higher quality.) JPG Cleaner - Removes Exif data from JPEGs, making the files smaller.
While data reduction (compression, be it lossy or lossless) is a main goal of transform coding, it also allows other goals: one may represent data more accurately for the original amount of space [5] – for example, in principle, if one starts with an analog or high-resolution digital master, an MP3 file of a given size should provide a better ...
GIMP's native format XCF is designed to store all information GIMP can contain about an image; XCF is named after the eXperimental Computing Facility where GIMP was authored. Import and export capability can be extended to additional file formats by means of plug-ins. XCF file size is extended to more than 4 GB since 2.9.6 and new stable tree 2 ...
High Efficiency Image File Format (HEIF) is a digital container format for storing individual digital images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text , audio and video.
A computer file format for coloured images, restricted to 256 colours and useful for small file-size. [8] GN: Guide number. A value indicating the power of an electronic flash apparatus, and used to estimate exposure. GN = distance × f-number. One needs to specify the film or sensor ISO speed, and it is conventional to quote for ISO 100/21°.
In GIMP 2.8, the Convert Image to Indexed Colors Option (Image→Mode→Indexed..) allows generation of an optimum palette with a choice in the number of colors from 2 to 256, the option of using a web-optimized palette, using a black and white palette (1 bit) or using a custom palette. It allows unused colors to be removed from the palette and ...
Even binary data files can be compressed with this method; file format specifications often dictate repeated bytes in files as padding space. However, newer compression methods such as DEFLATE often use LZ77 -based algorithms, a generalization of run-length encoding that can take advantage of runs of strings of characters (such as BWWBWWBWWBWW ).
