on OSX the g.drawstring is generally antialiased.
i have an application where it should not be.
i know that OSX is capable to render it not antialiased perfectly
when it has to print it on paper.
drawing to an 1bit picture is not an option (does not support
unicode characters).
drawing to a 32bit picture and then drawpicture to a 1bit picture
is not an option (text is ugly, because the hints of the font
rendering are not used and because letters do not always begin at a
pixel frontier).
is there some system call i can stop antialiasing for the current
graphics?
There may be a system call, but it would probably be pretty hard to
implement. I doubt that you could hook it up directly into the
Graphics class, which means that you would need to create a picture
with the text and then draw that picture.
You can fake or limit the affect of the anti-aliasing. You had the
right idea about drawing it to a 1-bit picture. You can instead draw
it to a 32-bit picture and then apply an RGBSurface.Transform(). You
create an array of Integers which is 255 elements in size, and then
loop through each value... the array index is the original value and
the stored value is the new value. For example, if you want
everything to be black-and-white:
Dim a(255) As Integer
For k As Integer = 0 To 255
If (k < 128) Then a(k) = 0 Else a(k) = 255
Next
But you can also set it up so that there are some levels of gray:
Dim a(255) As Integer
For k As Integer = 0 To 255
If (k < 100) Then
a(k) = 0
Elseif (k < 150) Then
a(k) = 100
Elseif (k < 200) Then
a(k) = 180
Else
a(k) = 255
End If
Next
