Centering text on an image using ImageMagick

barisdemiray · 09-20-2004, 02:33 AM

I'm writing a script that takes button labels from user and creates buttons by using ImageMagick internally. Script takes label and passes parameters to ImageMagick but i cannot center text on an template image. Is there any predefined words like vcenter,hcenter for the -draw parameter's string? Or any way to get the length of a string (in pixels) at courier font for example? Any ideas? Thanks!

Let me suggest you download a copy of;
abs-guide-2.6.orig
there is some information on string length in some of the examples on strings.

It may help.

Thanks for your time Dave. But i was trying to get the length of a string in `pixels'. But after a few hours i found the solution and there is no need to dive into pixels:

Code:

convert button-empty.png -font Verdana -pointsize 13 -gravity center -draw "text 0,0 'Sample Button'" button-sample.png

This will add the label "Sample Button" to your button-empty.png file with centering it. Also if we want to find the length of a string in characters, this can be done by:

Code:

[baris@rhinox]$ echo "This is a 30 character string"|wc -c
30

Anyway, thanks again Dave.
