I am using standard Ubuntu fonts:
Ghostscript helvetica
/usr/share/fonts/type1/gsfonts/n019003l.pfb
TrueType courier
/usr/share/fonts/truetype/msttcorefonts/Courier_New_Bold.ttf
/usr/share/fonts/truetype/msttcorefonts/Courier_New.ttf

All come out way too thick. If I use the exact same font in GD, it looks fine. When after I create the image:

Code: Select all

        _image->font("/usr/share/fonts/truetype/msttcorefonts/Courier_New_Bold.ttf");
        _image->fontPointsize(10);

and then when I want to draw the string (I do draw other stuff before the string)

Code: Select all

         _image->transformRotation(geo::radiansToDegrees(angle));
        // Rotate the points to match the rotation angle
        f.rotate(angle);
        t.rotate(angle);
        // Draw the text
        _image->draw(Magick::DrawableText(f.x(), t.y(), str));
        // Undo the rotation
        _image->transformReset();

The text is totally blurry and un-readable. I know it isn't the rotation code, as I can take that out and it is still unreadable.

If I crank my font size up to 30, I see an outline of the text in the color I wanted (black) and an inner-line in a different color (gray). Totally not what I expected. All I want is that inner-line of the font and at a 10 point size.

Any thoughts? This has me stumped.

Type 'identify -list format'. Check the TTF format. It should show that Freetype is associated with this format:

TTF* TTF r-- TrueType font (Freetype 2.4.6)

Do you have Freetype associated with your instance of ImageMagick?

I do have TTF support.

Code: Select all

identify -list format | grep -i TTF
    DFONT* TTF       r--   Multi-face font package (Freetype 2.3.11)
      OTF* TTF       r--   Open Type font (Freetype 2.3.11)
      PFA* TTF       r--   Postscript Type 1 font (ASCII) (Freetype 2.3.11)
      PFB* TTF       r--   Postscript Type 1 font (binary) (Freetype 2.3.11)
      TTC* TTF       r--   TrueType font collection (Freetype 2.3.11)
      TTF* TTF       r--   TrueType font (Freetype 2.3.11)

I have the same problem with Postscript fonts

Code: Select all

identify -list format | grep -i pfb
      PFB* TTF       r--   Postscript Type 1 font (binary) (Freetype 2.3.11)

What version of ImageMagick are you using? The latest is ImageMagick 6.7.4-1. We only have one patch against Freetype in this version but it might resolve the problem.

Try from the command line:

convert -font /usr/share/fonts/truetype/msttcorefonts/Courier_New.ttf pointsize 30 label:Magick x:

Does this return reasonable results (it does for us).

Is something missing from this command? It just hangs for me.

I am using Ubuntu 10.04.3 LTS.:
libmagick++-dev 7:6.5.7.8-1ubuntu1.1
imagemagick 7:6.5.7.8-1ubuntu1.1

here is a little test program:

Code: Select all

#include <Magick++.h>
int main(int, char**)
{
    Magick::Image image("100x120", "linen");
    image.font("/usr/share/fonts/truetype/msttcorefonts/Courier_New.ttf");
    image.strokeColor("black");
    image.fillColor(Magick::Color(0, 0, 0, MaxRGB));
    image.fontPointsize(10);
    image.lineWidth(2);

    image.draw(Magick::DrawableText(10, 20, "W 10TH ST"));
    image.draw(Magick::DrawableText(10, 40, "HIGHLAND PL"));
    image.draw(Magick::DrawableText(10, 60, "AIR HILL ST"));

    image.fontPointsize(40);
    image.draw(Magick::DrawableText(10, 100, "40"));

    image.write("/tmp/test.png");
}

which produces this image:

Instead of x: use label.pnm. Then use label.png. Do these renderings look ok? We agree something is wrong and we're trying to narrow down where in the code its misbehavin'.

We're offline for a few hours. We will get back to you later.

Looks like the convert program is working OK, which implies there is a problem with Magick++.

Interesting. If I make the outline transparent and the fill the color I want, it seems to be working:

Code: Select all

#include <Magick++.h>

int main(int, char**)
{
    Magick::Image image("100x120", "linen");
    image.font("/usr/share/fonts/truetype/msttcorefonts/Courier_New.ttf");
//    image.strokeColor("black");
//    image.fillColor(Magick::Color(0, 0, 0, MaxRGB));
    image.strokeColor(Magick::Color(0, 0, 0, MaxRGB));
    image.fillColor("black");
    image.fontPointsize(10);
    image.lineWidth(2);

    image.draw(Magick::DrawableText(10, 20, "W 10TH ST"));
    image.draw(Magick::DrawableText(10, 40, "HIGHLAND PL"));
    image.draw(Magick::DrawableText(10, 60, "AIR HILL ST"));

    image.fontPointsize(40);
    image.draw(Magick::DrawableText(10, 100, "40"));

    image.write("/tmp/test.png");
}

goofy, but I guess it makes sense in my mind. Although this is different than how the convert program seems to be working.....
