Graphics.DrawImageUnscaled blurry
-
I want to do a tile by myself, I can see that the result image is very blurry, and the positions of each piece are not correct(overlapped partly), why?
Bitmap bitmap = new Bitmap(2000, 2000, PixelFormat.Format32bppArgb); using (Graphics graphic = Graphics.FromImage(bitmap)) { Bitmap image = (Bitmap)Bitmap.FromFile(@"background.bmp"); for (int j = 0; j < 15; j++) { graphic.DrawImageUnscaled(image, (j % 4) * image.Width, (j / 4) * image.Height, image.Width, image.Height); } } bitmap.Save(@"a.png", ImageFormat.Png);Regards, unruledboy_at_gmail_dot_com http://www.xnlab.com

The images overlap because your code causes them to. To tile properly, just do j* width and j * height. You can also create a texturebrush which uses the bitmap and tiles, and then just fill the rectangle with that brush

hi, if I only do j*width and j*height, won't it only be tiling from top left to bottom right(diagonally)? and, it seems that the blurry problem only goes with some bmp files, strange :doh: by the way, I actually want to title all the pictures(not only one) in one picture, something like mosaic, so, texture brush maybe not suitable.
