WebJan 10, 2024 · I need to draw a line on a 32x32 white/black image using Bresenham's line algorithm. I have read_bmp and save_bmp functions, as well as function which sets color, function which draws a pixel and a function which draws a line. Unfortunately, when I complile my code, there is only pixel showing in a result.bmp file. WebSep 15, 2009 · You run Bresenham, but for each pixel (x,y), you actually draw (x,y), (x,y+1), ... (x,y+4). And if you want the ends of the line to be rounded, draw a circle at each end. For overkill, make a pixel map of the stylus (a circle or diagonal nib, or whatever), then draw a set of parallel Bresenham lines, one for each pixel in the stylus. Share

"Webmates the mathematical line connecting the two end points. In general, only the two endpoints lie exactly on the line, so the algorithm must decide which pixels in between are “close enough” to be considered on the line. The beauty of Bresenham’s algorithm is that it operates entirely in integer arithmetic, and is therefore well-suited to ... " - Derive bresenham line drawing algorithm
