Hi,

I have been using Graphics Mill to try to produce PNG images of text strings. These text strings need to be stretched to fit a set size which may not correspond to any standard font size (e.g. it might be taller than the font is).

I have this working, except that when I draw the text on a bitmap, and then resize it, I get dirty edges around the text. I am using white text, and I get gray lines around it after resizing.

The only thing I've found to fix this is to use NearestNeighbour interpolation, but that is low-quality interpolation and has its own problems.

Any suggestions as to how to fix this and have high-quality text?

I've attached some sample code. (If there are any other things I'm doing that aren't the best way, feel free to let me know that, too. I need the text to be anti-aliased on a transparent background, which is why I'm using GDI+.)

Thanks!

Chris

Sorry, there was a change I needed to make. newBitmap should not have been given a white background; it should be transparent. I'm not sure how that got in there.

tmpBitmap, tmpGraphics, and blackBoxSize are all because I need a graphics object so that I can call MeasureString so that I know how big to make the real bitmap (newBitmap). I rewrote this part so that it just uses newBitmap and resizes it to the size returned by MeasureString.

I've attached the new file. Sorry about the mistake and confusion.

Thanks,

Chris

That seems to do exactly what I want. I figured it had to do with anti-aliasing with black, but the things I tried to fix it didn't work. Thanks very much!
