Help with the Quality of image

[troelschristensen]

Hi.
I've been using your code on my site.
Right now I use the function latex2png to get a latex-image back in my other code. I'm coding in vb. Sorry. ;) It's working. But the quality is not the best. The scale defines how big the latex-image is, when it's beeing returned.
Larger image (Scale) = better image quality.

But when I set a scale too low, the quality is almost unreadable. Hope you understand my issue and can help me get better quality.

Kind regards.

Shared Function latex2png(Scale As Double, latex As String) As MemoryStream

        Dim parser = New TexFormulaParser()
        Dim formula = parser.Parse(latex)
        formula.GetRenderer(TexStyle.Text, Scale, "Calibri") 

        Dim pngBytes = formula.RenderToPng(Scale, 0.0, 0.0, "Calibri")
        Dim latexpng As New MemoryStream(pngBytes)

    Return latexpng
End Function

Try calling renderer.RenderToBitmap(0, 0, DPI), where DPI is a number bigger than the standard 96 (say, 192).

When in doubt, check the code of RenderToPng; I believe it only uses public stuff and is very simplified.
