Is there an easy way to get the dimensions of an image (width/height) without opening and reading the whole image? Perhaps using wand?

Reading a Jpeg2000 image can be expensive when all I need is the image width and height to allocate memory.....

Thanks!

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

#include <Magick++.h>

int main(int, char**)
{
Magick::Image image("100x120", "linen");
image.font("/usr/share/fonts/truetype/msttcorefonts/Courier ...

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 ...

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 ...

I do have TTF support.

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 ...

I figured out who to translate my text start point with the rotation I am placing on the image which fixed my problem.

Still not sure what is going on with the font, but I will start another thread on that (if I need to) to prevent confusion with this thread.

Thanks!

Followup question.

Any idea why the font looks so much worse in Magic++ than in GD? It almost looks like Magic++ is forcing the font to bold where GD isn't. I have tried 5 or 6 different GhostScript fonts and see the same thing.

I am totally missing something. All I am trying to do is draw some text between 2 points. Quite often, this will be on an angle. My Google-foo has been failing me on this...

I know how to do this in GD (call gdImageStringFT) and how to do this in cairo (using pango), but I can not seem to figure it ...
