The transparent background also does no favors for visibility with this basic gray scale. We can check the GenerationDirectory and find FaceSpriteSheet.png: Notice that there are 5 colors used in the ‘face’ image, all of which correspond to our control scheme. This example shows a template image at 800% zoom, with each square of color representing one pixel. Let’s look at what a compliant template may look like: They can also function as another static pixel if explicitly included in the template, though they will not generate borders around themselves like bit/accent/fill pixels do.īackground pixels are default transparent.

Outline pixels are generated any time an active (colored) pixel is bordered by a background pixel, and by default are colored black. You can also include more than 8 bit pixels in a template, in which case, the bit pattern will repeat, with 9th pixel getting the value of the first assigned pixel, and so on until it repeats again.Īccent and fill pixels are static, allowing the user to set pixels that are always active. While BitSprite expects 8 bit pixels in a template, you can do less, which results in fewer unique combinations on the final sprite sheet. ‘Bit’ pixels are how our generator creates the variety between images, as these pixels switch between being active and displaying a set color, or inactive and becoming an outline pixel. So if your output is entirely transparent, check that your pixels are correctly colored on the template. Templates have a special color coding to determine how the pixels are read and later written.Īny deviation from these specific colors on a template will result in the offending color being treated as background. In this example, we’ll just use the venerable Microsoft Paint, but any editor should be fine, so long as you encode the template as a png. To create a template, open your favorite image editor. You will need to run all commands from inside the Bitsprite directory. The user has several options to designate colors, as well as ‘unfold’ the template to create symmetrical images.ĭownload the package and place it in an easy to reach place. After downloading the package, or the .exe, the user can use the command prompt to run the program, using flags to control the results. By taking the index of the variant as it lays on the sprite sheet, Bitsprite uses that index number to activate or deactivate certain designated pixels based on its representation as a binary number. BitSprite is a program that creates variants of an image across total sprite sheet of the resultant images.
