Byte Array to Bitmap Converter

This free online browser-based program turns a byte array into a visible BMP image. It groups the input bytes into sets of three, reconstructs one pixel from each set, and draws the pixels row by row from left to right. The bytes can be written as ordinary decimal values, such as "255, 128, 0", or hexadecimal values, such as "ff, 80, 00" and "0xFF, 0x80, 0x00". By default, the automatic mode examines the notation of the input values, determines whether they are decimal or hexadecimal bytes, and decodes them accordingly. Some values, however, are valid in both formats. For example, "10, 20, 30" can represent either decimal or hexadecimal bytes because every value is valid in either notation. In such cases, you can select "Read Decimal RGB Bytes" or "Read Hex Bytes" to tell the program exactly how to interpret the data. The program accepts plain byte lists, one-dimensional arrays, pixel-grouped arrays, row-grouped arrays, and fully nested structures produced by the Convert Bitmap to Byte Array tool. It also accepts custom byte and pixel separators made from punctuation or whitespace. You can use the "Byte Order" option to specify how the three color channels are arranged in every pixel. Select RGB for red-green-blue data, BGR (blue-green-red) for the channel order commonly used in 24-bit BMP pixel storage, or any of the four other channel arrangements. To arrange the decoded pixels into bitmap rows, enter the number of pixels per row in the "Width" option. If the input is already divided into lines or nested rows of the correct length, you can leave the width empty and preserve that existing structure. Any incomplete pixel, as well as any missing position at the end of a shorter row, is replaced with the selected "Fill Color". You can also increase the "Pixel Size" to turn every data pixel into a larger, sharp-edged square, making compact byte-array images easier to view or use as pixel art. Bmp-abulous!
