Line Attributes X 1 Y 1 X 2

Line Attributes (X 1, Y 1, X 2, Y 2, Color) The Line Based on Slope Decision on the dx and dy Loop on Greater (Counter of 1) Increment of other (Slope) Plot Pixels in the loop BY Kamran Yousaf

Line ‘dx’, ‘dy’ to calculate the diffrence along x and y axis ‘steps’ to calculate Loop counting ‘x. Inc’, ‘y. Inc’ to calculate the Difference covered in each step ‘x’ , ‘y’ to store current pixel position ‘i’ as a loop variable BY Kamran Yousaf

Line Calculate ‘dx’ as x 2 -x 1, ‘dy’ as y 2 -y 1 ‘steps’ will have the greater absolute value from ‘dx’ or ‘dy’ ‘x. Inc’ is ‘dx’/’steps’ , ‘y. Inc’ is ‘dy’/’steps’ ‘x’ is ‘x 1’ ‘y’ is ‘y 1’ Plot 1 st pixel at ‘x’, ’y’ using ‘color’ Loop ‘k’ 1 to steps and ‘x’+=‘x. Inc’, ‘y’+=‘y. Inc’ BY Kamran Yousaf
