Font size not correct while annotating - magick++

[writetonsharma]

I am using imagemagick 6.7.3 on windows XP compiled with Visual Studio 6.0.
I have the below code to annotate some text and I see that the font size is not set correctly. I doubt that a default font size is picked.

Code: Select all

Image image( Geometry(713,8), Color("#ffffff"));
image.fillColor("#000000");
image.density( Geometry(96, 96));
image.font("@.\Arial.ttf");
image.fontPointsize(5);
image.annotate("A long text here", WestGravity);
image.rotate(270);
image.write("test.png");

Other surprising thing I see is, if I change some sequence of the code, the font size changes to something else. Like if I set the font point size in the end.

Code: Select all

Image image( Geometry(713,8), Color("#ffffff"));
image.fillColor("#000000");
image.density( Geometry(96, 96));
image.font("@.\Arial.ttf");
image.annotate("A long text here", WestGravity);
image.rotate(270);
image.fontPointsize(5);
image.write("test.png");

I am not an expert but I think something is wrong. Depending on where I put set the font size, the font either become too large or too small.


Thanks,
Naveen.

Set the density to 72 then adjust your font pointsize.

Thanks for looking at it.

I tried that -

Code: Select all

image.density( Geometry(72, 72));

But its still not working.

see the image. The top font is the correct one. Rest two below are either smaller or bigger.

Thanks.

You also need to set your font pointsize before you call image.annotate().

[writetonsharma]

yes, I did that only. So, its like the below code

Code: Select all

Image image( Geometry(713,8), Color("#ffffff"));
image.fillColor("#000000");
image.density( Geometry(72, 72));
image.font("@.\Arial.ttf");
image.fontPointsize(5);
image.annotate("A long text here", WestGravity);
image.rotate(270);
image.write("test.png");

Did I do correctly ?

[magick]

Change "@.\Arial.ttf" to "@Arial.ttf". We're using ImageMagick 6.8.5-8, the latest release and it appears to render the font correctly.

I tried this but the output is still the same. The font is bigger than 5point.

I can try the latest release but I was avoiding it. We use various non-windows platforms and it will take some time to compile the library on all these platforms with our new release due soon.

Do you think I can do something else in 6.7.3 to make it work ?
