This application consists of steganography and image compression. The message insertion and extraction method uses a modification of the LSB and RPP methods with the RPE method. While the zip and unzip process in image compression using the LZW and huffman methods.
Images that can be processed in this application are images with bitmap format (* .bmp) and PNG format (* .png). Especially in image compression, the compressed image format will change according to the image compression method used. For example, an image with a bitmap format which compressed using the LZW method will generate a new compressed file with an additional format (.LmZWp). Whereas image compression using the huffman method will produce a new compressed file with the format (.huffz)
