SAR Image Processor, Freeware version 5.7
Last updated 11/21/20
SAR Image Processor is a freeware image editing program for the PC.
People will mostly want it for its enlargement capabilities.
See (New with version 5.6) Comparisons of Image Enlargement Methods.
- (New with version 5.5)
- 2X and 4X image enlargement using a neural network, more specifically, a multilayer perceptron (MLP).
- The capability for a user to create and train their own MLP for enlargement.
- CommandLineSAR64.exe 5.5, which is included with SARimageProcessor.exe 5.5, will need vcomp140.dll, which is included.
- (New with version 5.4)
- TARGA (.tga) file support, uncompressed RGB and RGB Alpha, 8 and 16 bits/channel. Good for editing Quake 3 textures!
- Alpha channel support, which includes reading/writing PNG and TARGA files with alpha.
- Optional Undo (Ctrl+Z).
- Load images from clipboard (Ctrl+V).
- CommandLineSAR64.exe 5.4, which is included with SARimageProcessor.exe 5.4, doesn't need vcomp110.dll.
- (New with version 5.2)
Starting with v. 5.2, for some operations, SAR Image processor, which is a 32 bit program, can call a 64 bit command line program, CommandLineSAR64.exe, to do its work. The advantages are that larger image files can be processed, and, if the "Parallel Processing" option is selected, processing will be faster on computers with multiple core CPUs. With v. 5.2, the only operations that can use CommandLineSAR64.exe are PseudoLAD, Hysteresis Pyramid and Farbman Pyramid. Put CommandLineSAR64.exe in the same directory as SARImageProcessor.exe.
- (New with version 5.1)
SAR now accepts one input and one output image file name from the command line. After counting exactly three items on the command line, SAR hides its window, then reads the input file, then applies the F2 programmed operation, then writes the processed image to a file with the output name, and then automatically closes. Except for maybe 0.1 seconds, SAR's window is hidden and, hopefully, out of focus. Parameters must still be set from within SAR's GUI interface, but whenever SAR is closed, those setting remain (stored in sar.ini). This feature will allow other programs to use SAR. Some automatic control of parameters can be accomplished by selecting one of several previously stored and renamed versions of the sar.ini file.
