Each of the parameters must be en the correct case. For example the resize paramater must not be like this Resize, only lowercase. |

Before you can use the resizing and cropping feature, the sync user from this section DFS 11.1 - 3 Setting up Sitecore, must have the Digizuite role |
Each parameter is described as follows:
Field | Description | ||
|---|---|---|---|
SiloId | This is the Id of the silo that has the asset requested. | ||
AssetId | Is the Id of the asset that is requested. | ||
Quality | Overrides the quality specified in the Sitecore field. Quality supports both 'by name' and 'by id' | ||
Resizeresize * | Only applies to image assets. One of the concepts and principles when using a DAM system is to use specific qualities for every use. If images are needed in different sizes, it should be configured in Digizuite™ DAM. However, there is a resize feature. Width How wide the image will be in pixels. Height How high the image will be in pixels. By default a resize does not keep aspect ratio, but you can set an option to keep aspect ratio. | ||
Cropsizecropsize * | Only applies to image assets. You must supply a width and height. The way these parameteres are used is based on the cropmode and the cropposition. If the cropmode is PixelBased then crop width and crop height are interpreted as pixels. If the cropmode is AspectRatioBased then crop width and crop height are interpreted as an aspect ratio. For instance, for the aspect ratio 1:2, the image is cropped to the largest possible image with the given aspect ratio. | ||
Cropmodecropmode * | How to interpreted the crop width and crop height.
| ||
cropposition * | When cropping, the focus point can be one of the following.
| ||
outputimageformat * | Control the output format, when resizing and or cropping. If this property is not set, the output format will be the same format as behind the quality property.
| ||
compress * | Only applies to image assets. Indicates whether the asset should be saved using a worse quality, thereby reducing the physical size. from 0-100 is allowed, where 0 is the worst quality, but least physical storage. | ||
Optionsoptions * | Options is a dash ("-") separate list and can contain these options: download - Will download the asset requested. keepaspectratio - Will enforce aspect ratio on from the original asset, if a resize is requested. boxfit - If a resize ia requested and you supplyed both the width and heigth. The resized image will not exceed these values and still keep the aspectratio. upscaleallowed - Will allow upscaling an image. The default is to disallow that. |

Here are some use cases, that shows how the media handler works and how it is used in different situations.
This is the shortes url, these are the required parameters. Here we request the assetId 192 and the quality format id 3 (rendition from Digizuite)./dfsmedia/baeefe6b74df44be8a2bccfb2c57af8e/192-3
Resize , that will resize the image to a width of 350 px and keep the aspect ratio of the height./dfsmedia/baeefe6b74df44be8a2bccfb2c57af8e/192-3/resize/350x0
Resize , that will resize the image to a width of 350 px and a height of 350 px. This will not respect the aspect ratio of the imageof the image./dfsmedia/baeefe6b74df44be8a2bccfb2c57af8e/192-3/resize/350x350
Crop, this is the shortest use of the crop feature, this will set the cropmode to AspectRatioBased and then set the resizing width to 400 and the height to 100./dfsmedia/baeefe6b74df44be8a2bccfb2c57af8e/192-3/resizecropsize/350x350
Crop, this is the shortest use of the crop feature, this will set the cropmode to AspectRatioBased and then set the resizing width to 400 and the height to 100./dfsmedia/baeefe6b74df44be8a2bccfb2c57af8e/192-3/cropsize/400x100
The above url would be the same as this400x100
The above url would be the same as this./dfsmedia/baeefe6b74df44be8a2bccfb2c57af8e/192-3/resize/400x100/cropsize/400x100/cropmode/AspectRatioBased
This will crop with an aspect ratio 4:1 and crop from the top left corner and then resize down to width 400 px and height 100 px./dfsmedia/baeefe6b74df44be8a2bccfb2c57af8e/192-3/resize/400x100/cropsize/400x100/cropmode/AspectRatioBased/cropposition/TopLeft
Understanding the DigizuiteMediaCache
The DigizuiteMediaCache is where everything, except videos, is saved. Below is a flow chart how it works when requesting media from the DFS mediahandler.
...
The cache location is configurable and is located in DFS.Settings.config

From version DFS 11.1 the default resizing feature has been rewritten. The resizing it now done in Digizuite, this also requires that DAM version is minimum 5.10.5. If you are connecting to a DAM less then 5.10.5 and you are using the resizing feature, then you must enable the old resizing processor.
