Class CmsVfsImageWidgetConfiguration

java.lang.Object
  org.opencms.widgets.CmsGalleryWidgetConfiguration
      org.opencms.widgets.CmsVfsImageWidgetConfiguration

public class CmsVfsImageWidgetConfiguration
extends CmsGalleryWidgetConfiguration

Configuration options for the VFS image widget.

The configuration options are read from the configuration String of the widget.

The configuration String has to be formatted as JSON object, with the following possible keys:

• class: optional class implementing I_CmsImageWidgetDynamicConfiguration to dynamically configure startup parameters and format values.
• formatnames: list of format names to select, with pairs of selectable value and selectable text, e.g. value1:optiontext1|value2:optiontext2
• formatvalues: corresponding format values to the format names list, can be dynamically generated by the dynamic configuration class. The list of values should contain width and height information, with a '?' as sign for dynamic size and with an 'x' as separator for width and height. Example: ['200x?', '800x600']
• scaleparams: default scale parameters (no width, height or crop information should be provided!)
• startup: the startup folder, can be dynamically generated by the provided class, in that case, use 'dynamic' as value.
• type: the startup folder type, can be 'gallery' or 'category'. Can be dynamically generated by the provided class, in that case, use 'dynamic' as value.
• usedescription: indicates if the description input field for the image should be shown or not.
• useformat: indicates if the format select box for the image should be shown or not.

An example configuration can look like this:

{scaleparams: 'q:70,r:2,c:CCCC00', type: 'gallery', startup: '/demo_en/images/', usedescription: true, useformat: true, formatnames: 'imageleft:Image left|imageright:Image right|imagetop:Image top', formatvalues: ['150x?', '250x300', '?x250']}
