Image::Magick "geometry" atribute ??

[Tommy Butler]

Many of the methods in Image::Magick require an argument named "geometry".
The docs at http://www.imagemagick.org/www/perl.html are very vague about this.
I don't understand what the "geometry" argument is for, and I don't understand
what kind of values to assign it. It requires a syntax that I can't grasp.
Can someone enlighten me?

Example taken from the documentation:
$x = $image->Crop(geometry=>'100x100"+100"+100');

A few methods that require the "geometry" argument, as described in the docs:
+-------------------+------------------------------------------------------+
| Method | Parameters |
+===================+======================================================+
| AdaptiveThreshold | geometry=>geometry, width=>integer, height=>integer, |
| | offset=>integer |
+-------------------+------------------------------------------------------+
| Blur | geometry=>geometry, radius=>double, sigma=>double |
+-------------------+------------------------------------------------------+
| Border | geometry=>geometry, width=>integer, height=>integer, |
| | fill=>color name |
+-------------------+------------------------------------------------------+
| ColorFloodfill | geometry=>geometry, x=>integer, y=>integer, |
| | fill=>color name, bordercolor=>color name, |
| | fuzz=>double |
+-------------------+------------------------------------------------------+
| Crop |geometry=>geometry, width=>integer, height=>integer, |
| |x=>integer, y=>integer |
+-------------------+------------------------------------------------------+
| Emboss | geometry=>geometry, radius=>double, sigma=>double |
+-------------------+------------------------------------------------------+

Some help please?

Many of the methods in Image::Magick require an argument named
"geometry". The docs at http://www.imagemagick.org/www/perl.html are
very vague about this. I don't understand what the "geometry"
argument is for, and I don't understand what kind of values to assign
it. It requires a syntax that I can't grasp. Can someone enlighten
me?

The documentation has several examples, as well as short lines stating
that geometry generally is short for widthXheight. This is generally the
case, although the 3rd and 4th argument chane their meaning sometimes,
depending on the methods called. Sometimes the geometry attribute can be
used with special characters that limit or extend its meaning, like
percentages for resizing. See the link below.

More information about geometry can be found in the generic manual pages
for the ImageMagick tools, and under the command line options to these
tools. See, for example

http://www.imagemagick.org/www/utilities.html

Without writing a complete reference for all methods (been there, done
that), I can't be that much more helpful.

I'd advise you to not use the geometry attribute, when there are options
that allow you to avoid it.

I didn't know I did. But sorry.

I didn't know I could avoid it anywhere, but hey, I'll try! Thanks for the
info. Really, thanks very much.
