Bresenham Line Generation Algorithm for Positive Slope
(BLD algorithm for positive slope (0 < m < 1)
- If slope is negative then utilize reflection transformation to transform the line segment along with -ve slope to line segment along with a +ve slope.
- Determine constants 2Δy, 2Δy - 2Δx, Δy, Δx at once for all lines to be scan converted, consequently the arithmetic engages only integer subtraction or addition of these constants.
Image Editing Tools These are specializing and influential tools for enhancing and re-touching existing bit-mapped images. Such applications also give several of the features a
