How to deal with color loss on GDI+ Image Resize?
- by user125775
Hello All,
I am resizing images with C#/GDI+ using the following routing
bmpOut = new Bitmap(lnNewWidth, lnNewHeight);
Graphics g = Graphics.FromImage(bmpOut);
g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBilinear;
g.FillRectangle(Brushes.White, 0, 0, lnNewWidth, lnNewHeight);
g.DrawImage(loBMP, 0, 0, lnNewWidth, lnNewHeight);
and encoding it with the highest quality.
System.Drawing.Imaging.Encoder qualityEncoder = System.Drawing.Imaging.Encoder.Quality;
EncoderParameter myEncoderParameter = new EncoderParameter(qualityEncoder, 100L);
However, the images that I get have significant loss of color (I am using JPG images only). The quality is perfect, but color is washed away. Do you have any idea what is goingf on?
Thanks a lot in advance.
