Drawing lines and ellipses with DirectDraw
Hey everyone, this is my problem: I want to draw a line and an ellipse, but DirectDraw has no built-in features to do so, except for in VB. Searching through my book and my brain, I came up with only two solutions: manually calculate the position of each pixel, then lock the surface and plot them; or make a call to GetDC, and use GDI to draw the line. The latter is from my unreliable book, and uses the reputedly slow GDI. However, I have no idea if the manual calculate/plot approach would be any faster. Which method should I try?
