| 29 | # This script is an alternative to translate.pl that uses ImageMagick
|
---|
| 30 | # instead of Gimp to generate the button images. The advantage of using
|
---|
| 31 | # ImageMagick is that it supports Unicode (and other multibyte encodings).
|
---|
| 32 | #
|
---|
| 33 | # This script requires the following components installed:
|
---|
| 34 | #
|
---|
| 35 | # - A recent version of ImageMagick, and the PerlMagick extensions.
|
---|
| 36 | # (http://www.imagemagick.org)
|
---|
| 37 | #
|
---|
| 38 | # - The FreeType libraries (http://freetype.sourceforge.net)
|
---|
| 39 | #
|
---|
| 40 | # The script reads through the macrofile specified at the command line,
|
---|
| 41 | # and generates images for each of the image macros. It does this by
|
---|
| 42 | # 'pasting' the button text onto a set of pre-generated images, using the
|
---|
| 43 | # annotate.pl script. The background images used, and the arguments to
|
---|
| 44 | # annotate.pl, depend on the type of image (eg. nav_bar_button) being
|
---|
| 45 | # generated.
