UploadImage

A clickable image similar to the upload object. Pressing this button will show a popup that allows to upload one or more files.

In order to enable the upload, you should use UISET to set the path attribute of the id of the upload object to a valid path under the HSYCO main directory.

Saving to directories outside of the HSYCO directory is never allowed.

The path attribute can be set globally or for a specific session, in order to authorise a specific user only.

When the upload is complete, HSYCO calls the userCommand JavaScript or Java callback:

userCommand(session, userid, name, param)

HSYCO also executes all actions associated to the event:

USER name=param

defined in EVENTS, where name is the upload object's id, and param is the name of the uploaded file (without the path).

If the multiple attribute is set to true, allowing the upload of multiple files, the user callback is called for each uploaded file.

Note that, for security reasons, the UISET must be executed on the server-side code (EVENTS, JavaScript or Java). A client-side UISET would be ignored.

Parameters

• id: the object's ID, used by UISets
• image: image filename
• position: the object's position. Use the pixels or rows and columns coordinates format
• size: the image's width and height
• label: the text label next to the image. It can contain HTML tags
• css: the label's css attributes
• multiple: true/false, specifiies if the upload will accept multiple files

Syntax

(uploadimage!<id> <image's filename>; <position>; <width>; <height>; <label>; <css>; <mutiple>)

E.g.

(uploadimage!download1 myimage.png; r8c7; 100; 100; Label; (font-style:italic; top:-15px))

	false	Stop the blinking
opacity	0.0 ... 1.0	Object opacity from 0 (not visible) to 1 (fully visible)
rotation	0 ... 360	Object rotation in degrees. Images are rotated around the center point, all other objects are rotated around the top left corner
