In the header file, each BMP that is processed by the script will have its filename appended as a comment before the HEX output. Here are the contents of that file (in this case, data for the â4â character): #includeYou can see from the output that my_header.h was successfully created by the script. Our example image is 24 pixels wide so we want header data to be 3 bytes wide (24-pixels/8-bits = 3 bytes). You will be asked to input the desired column width for the images. Run the file, with your BMP images as the command line arguments. Generating header file with a byte width of: 3 bytes Please enter how many bytes (8-bits) wide Repeat this for each character you wish to include in your new font header file.Äownload our bmp2header.py file. From this menu, choose âUse black and white(1-bit) paletteâ. To do so, click on the Image menu at the top, go to Mode and select âIndexedâ¦â. We also need to make this an indexed image. Do this by clicking the Image menu, go to Transform, and select âFlip Verticallyâ. You should make sure that the Antialiasing checkbox of the font tool is not selected.Ä«MP files are saved from bottom to top, we need to invert the image for our purposes. Adjust the size and location until if fills the canvas. Using the font tool, select your desired font and add your character. In this case, weâre interested in generating a set of fonts that will display in a 24Ã30 pixel area. Height is up to you, but the width should be in multiples of 8 to correspond to the 8-bit wide storage scheme. Open the GIMP and create a new file with the dimensions that you require. This can be used for generating fonts, or converting larger images. This data can then be read out of the array and manipulated in the AVR code for use in whatever format you need for your display. The Python script takes one or more 1-bit color palette indexed BMP images, cuts out the header and any unused column data, and outputs a header file with the information stored in a one dimensional array in PROGMEM. We are working on an Ubuntu 9.04 system but because these are cross-platform tools you should be able to do this on any OS. Weâll walk you through it after the break.įor this tutorial we will be using the GNU Image Manipulation Program in conjunction with Python. Our python script will convert BMP files into a header file ready for use with AVR microcontrollers. Weâve used some readily available tools to make this a bit easier for your next project.
