Image quality difference

Question

0.00/5 (No votes)

I have made a customised 'run time' image using C# graphics.

I set everything to get the high quality image.

C#

obj.SmoothingMode = SmoothingMode.HighQuality;
obj.CompositingQuality = CompositingQuality.HighQuality;
obj.PixelOffsetMode = PixelOffsetMode.HighQuality;
obj.InterpolationMode = InterpolationMode.HighQualityBicubic;
obj.PageUnit = GraphicsUnit.Display;

The output is loading fine in WPF, but same image does'nt have enough brightness if we are loading on ASP.NET page.

Red lines become dark red lines in asp.net page.

Any idea, what is the reason?

To be frank, I don't need anything, but you probably do. :-) I just don't see any clue from your code. If you screw up anything, it's not in this fragment of code. The problem looks strange. I would do some tests. Save the picture from the Web page and compare with original. Something like that... I have nothing except your short fragment. I have no idea what else do you have...

An asp page is shown in a browser, the browser is responsible for rendering the image (and different browsers may handle that differently...). In a WPF application, it is that WPF application to render the image (it will have the .NET framework doing that job).
That means, the differencesare likely caused by different rendering engines.
