Enables creation of cropped and scaled images. This plugin also allows for simple modification of the home slideshow image as the new crop ability can create fitting images from resources within the system. The main intention is to provide custom downloads but you can also create alternative files for the original image. Descriptions of the different functions are listed below.
To open the transform plugin:
- Browse to your Resource of choice
- Select "Transform" from Resource Tools
Or you can access it from the edit page in a collection. (See Edit Collection)
Note that this is only available if 'Enable Batch Transform' is set in the plugin configuration page. The options for the collection are all fairly straightforward, a few extra tips:
CW - Clockwise, CCW - Counter Clockwise
This will apply the action to all resources within that collection that fit the configured requirements.
Crop: To crop the image you need to drag+click the image to select the area of image that you want. Once selected, you can drag the edges around using the usual boxes on the edges or you can use the width and height indicators and move the box around by clicking in the centre of the box.
Embed resolution information
If enabled this will embed suggested resolution information in the image metadata (used by software such as Photoshop).
Please be aware that embedded resolutions do not change the actual size or quality of the resultant image and any image can be printed at any size once downloaded.
Quality option (version 8.5+)
If the plugin option 'Allow user to select the quality of resultant file (JPG/PNG only)' is enabled the user will have the option to choose from a predefined list of quality settings (JPG and PNG files only). The available options can be changed by a system administrator in the global system configuration file using the '$image_quality_presets' array variable.
Use sRGB option (version 8.5+)
If enabled by the administrator, the user can ensure that the resultant file is created with the sRGB profile. If the option is not available then by default all transformation actions will use the sRGB profile.
Replacing Homepage Slider Images
Having clicked transform under the resource do the following:
- Tick the box "Replace slideshow image"
- You must then drag out a crop area on the preview image on this page
- Enter a sequence number (1 to 10)
Matching Resolution size will stop image stretching and effects occurring.
