Image to Byte array
Use this online image to Byte array tool for converting (monochromatic) bitmaps to data arrays (C++ style). You can use these arrays with programs for embedded systems with microcontrollers to output graphics on monochromatic LCD's or thermal printers (like Arduino with the Adafruit mini printer, which I needed this for). Probably the output also works for graphics monochromatic LCD displays like T6963C, KS0108, SED1335 etc. but haven't tested this yet.
This tool was meant as a quick online version of LCD Assistant, which is Win only. It creates files for use with a C compiler: for AVR, ARM, PIC, 8051 and ohter microcontrollers. You can use it directly with Arduino (tested), or probably any other design environment based on C compiler (not tested).
How to
To convert an image from bitmap file (.jpg/.png/.gif, RGB/Grayscale) to a data array, simply upload it and hit 'Convert'.
This tool uses 8 pixels per byte and will try to auto-convert your image to black & white. It seems to have some problems with images containing indexed colors, so use RGB/Grayscale. Also; I got the best results with the Adafruit printer by using images with a width of a multiple of 8 (eg. 384 pixels wide).
