(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

WebThe Bresenham Line-Drawing Algorithm. The basic Bresenham algorithm. Consider drawing a line on a raster grid where we restrict theallowable slopes of the line to the range . If we further restrict the line-drawing … To derive Bresenham's algorithm, two steps must be taken. The first step is transforming the equation of a line from the typical slope-intercept form into something different; and then using this new equation to draw a line based on the idea of accumulation of error. Line equation The slope-intercept … See more Bresenham's line algorithm is a line drawing algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points. … See more Bresenham's line algorithm is named after Jack Elton Bresenham who developed it in 1962 at IBM.

You could let the above loop run until your x/y ratio is equal to tan (30 degrees), then start actually drawing until your ratio hits the value at which you want to stop. Not the most efficient way, but it will work. To get it better, you'd need to pre-calculate your starting 4 var values. how do cantilevers work

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 ... WebAlgorithm.
