    Gemc

    Gemc

    Prepare your CD images (BIN,CDI,NRG,CCD or similar) for compression

    ...HERE`S HOW TO USE IT: Run the CD image file (i.e. filename.bin) through GEMC to create an ECM file (i.e. filename.bin.ecm). Compress the ECM file (i.e. filename.bin.ecm) using your favorite compression program (i.e. 7Z,RAR,ZIP..). Back up, transmit via Internet, or whatever you normally do with CD images! When you want to burn the CD again, extract the original CD image from the ECM file. space saved depends on the number of sectors with unnecessary EDC/ECC data in them, which will depend on the specific type of CD

    PyInstaller

    PyInstaller

    Converts (packages) Python programs into stand-alone executables

    PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. ...

    bmp2rle

    Encode bitmap(bmp) file with run-length encoding

    Encode bitmap(bmp) file with run-length encoding(RLE), just like RLE4 and RLE8, but extend to RLE16, RLE24 and RLE32. Usually, this project will be used in GUI of embedded system, to make the image files smaller, and save the IO bandwith. If the GUI support JPG or PNG, the compression ratio is much better than RLE, but how about the embedded system encounters both caculate limitation and IO bandwidth limitation? Try this project, I hope it can make a banlance between caculation and bandwidth. But first of all, you should know that the compression ratio of RLE is highly depend on the bitmap file data, the ratio can larger than 1, only when the same color continuously repeats in one line, it will gain a smaller compression ratio.
