changing bitmap colors

[.paul.]

i'm trying to change some colors in a bitmap.
this is the code i'm using

Dim att As System.Drawing.Imaging.ImageAttributes = New System.Drawing.Imaging.ImageAttributes
Dim map As System.Drawing.Imaging.ColorMap = New System.Drawing.Imaging.ColorMap
map.OldColor = Color.FromArgb(0, 0, 0)
map.NewColor = Color.FromArgb(255, 255, 255)

this is the part i can't work out

att.SetRemapTable(New System.Drawing.Imaging.ColorMap, map)

and i'm not sure how to use the drawimage statement after.

Thread moved to Graphics forum. Please post to specialized forums rather than General ones.

SetRemapTable Method have two overloads, first takes a ColorMap as parameter, second takes a ColorMap and a ColorAdjustType value.

About usage you could read How to: Use a Color Remap Table.
