I am generating some buttons using ImageMagick. However, I am not able to set the spacing between the letters in generated image. Command which I use:

convert -gravity center button_subscribeme.png -font /usr/share/fonts/truetype/msttcorefonts/Arial_Bold.ttf  -fill white -draw "text 0,0 'CLICK ME'"  -font_stretch 10  render/mailbox-submit.png

throws:

convert: unrecognized option `-font_stretch' @ error/convert.c/ConvertImageCommand/1561.

So I guess font_strech is not proper option. How I can achieve it? Generated text is too narrow.

    There is no ImageMagick parameter named -font_stretch that I know of. However, there is -stretch.

    But I don’t think that -stretch really works with fonts. In any case, to find out what sort of values are possible, just run:

    convert -list stretch

    and see the result:

    Any
Condensed
Expanded
ExtraCondensed
ExtraExpanded
Normal
SemiCondensed
SemiExpanded
UltraCondensed
UltraExpanded

    Use -kerning !

    Better use the -kerning commandline parameter. It takes positive as well as negative values:

    convert \
  in.png \
 -gravity center \
 -font "/Library/Fonts/Arial Bold.ttf" \
 -kerning -0.5 \
 -fill white \
 -draw "text 0,0 'CLICK ME'" \
  out1.png

    or

    convert \
  in.png \
 -gravity center \
 -font "/Library/Fonts/Arial Bold.ttf" \
 -kerning 1.5 \
 -fill white \
 -draw "text 0,0 'CLICK ME'" \
  out2.png

    Works for me on ImageMagick version 6.7.8-3 2012-07-19 on Mac:

    <code>-kerning -0.5</code> <code>-kerning 1.5</code>
