manipulate images at pixel level in C#

Question

I have a ppm file and I figured out how to mirror the image from the middle but I can't figure out how to horizontally flip it. this is the code for the mirror function:

{R[x][y]=R[WIDTH-x][y]; G[x][y]=G[WIDTH-x][y]; B[x][y]=B[WIDTH-x][y];}}

the horizontal flip function should look almost the same as above. but achieve a flipped image.

Answer 1

Use System.Drawing.Bitmap

• GetPixel()
• SetPixel()

The MSDN Documentation for System.Drawing.Bitmap
