ImageCache is a dynamic image manipulation and cache tool. It allows you to
|
||||
create a namespace that corresponds to a set of image manipulation actions. It
|
||||
generates a derivative image the first time it is requested from a namespace
|
||||
until the namespace or the entire imagecache is flushed.
|
||||
|
||||
Getting Started:
|
||||
|
||||
1. Upload and enable both the ImageCache and ImageCache UI modules.
|
||||
|
||||
2. Go to Administer -> Site Building -> ImageCache. Click on the local task tab
|
||||
labeled "Add New Preset" to build a new set of image manipulation actions.
|
||||
|
||||
3. Enter a descriptive name of your choice (e.g. 'product_thumbnail') into the
|
||||
"Preset Namespace" box and click "Create New Preset".
|
||||
|
||||
4. Add actions to your preset that tell ImageCache how to manipulate the
|
||||
original image when it is rendered for display. Available actions include
|
||||
crop, scale, desaturate (grey scale), resize, and rotate. Multiple actions
|
||||
may be added to a preset.
|
||||
|
||||
5. Each action is configured in its own form, and the actions may be reordered
|
||||
from the preset's configuration form. If you need to make any changes to the
|
||||
order of actions in a preset, remember to click "Update Preset" when you're
|
||||
finished.
|
||||
|
||||
Viewing Manipulated Images:
|
||||
|
||||
Your modified image can be viewed by visiting a URL in this format:
|
||||
|
||||
http://example.com/files/imagecache/preset-name/files/image-name.jpg
|
||||
|
||||
For example, if your preset is named 'product_thumbnail' and your image is
|
||||
named 'green-widget.jpg', you could view your modified image at:
|
||||
|
||||
http://example.com/files/imagecache/product_thumbnail/files/green-widget...
|
||||
|
||||
NOTE: Each role that wishes to view the images generated by a
|
||||
particular preset must be given permission on the admin/user/permissions
|
||||
page.
|
||||
|
||||
ImageCache also defines a theme function that you can use in your modules and
|
||||
themes to automatically display a manipulated image. For example, to use the
|
||||
theme function in a .tpl.php file, add the following line where you would like
|
||||
the image to appear:
|
||||
|
||||
<?php
|
||||
print theme('imagecache', 'preset_namespace', $image_filepath, $alt, $title, $attributes);
|
||||
?>
|
||||
|
||||
Change 'preset_namespace' to the name of your imagecache preset and make sure
|
||||
that $image_filepath or some other variable contains the actual filepath to
|
||||
the image you would like to display.
|
||||
|
||||
$alt, $title and $attributes are optional parameters that specify ALT/TITLE
|
||||
text for the image element in the HTML or other attributes as specified in the
|
||||
$attributes array.
|
||||
|
||||
Using ImageCache with Contributed Modules:
|
||||
|
||||
ImageCache presets can be put to use in various other modules. For example, when
|
||||
using CCK with the Imagefield module, you can use the "Display fields" local
|
||||
task tab to choose a preset to apply to images in that field. Similarly, you
|
||||
can specify a preset when displaying images attached to nodes using Imagefield
|
||||
in a View through the Views UI.

||||

||||
|
||||
(Images, page names, and form field names may refer to previous versions of
|
||||
ImageCache, but the concepts are the same.)
