Skyway Image Skyway ImageThe Skyway Image web control allows you to display a picture or image on a web page. This web control can display either a static value or a variable, and if required, the user has the ability to modify the appearance of the image. Additionally, Skyway Image controls can be configured to display based on the results of one or many true/false test conditions. If the conditions evaluate to "true", the image is displayed, otherwise the image is omitted from the web page.
Setting Parameters
The image to be displayed on the web page.
Variable - select the variables that store the source, filename and mime type information for the image. Only valid variables from the current Web Model are enabled in the Source, Filename and Mime Type dropdowns. In the Alternate Text field, you may also identify text that will appear with the broken image icon if the image file is ever unaccessible at runtime.
Static Values – use the Browse buttons to navigate to the location of the Source and Rollover Source image files on your file system. The Rollover Source image is optional; however, if identified, the source image will change to the rollover image when a user hovers the mouse over the source image at runtime. In the Alternate Text field, you may also identify text that will appear with the broken image icon if the image file is ever unaccessible at runtime.
Alignment - if the Skyway Image is being embedded within a table, identify whether the image should be aligned right, left or center within the table cell or not be aligned at all
Layout - if the Skyway Image is being embedded within a table, identify the vertical and horizontal spacing (in pixels) from the table cell borders
Size - to customize the size of the image within the web page, select Specify Size checkbox then identify the image width and height (in pixels)
The conditions to be evaluated to determine whether to display or not display the Skyway Image web control at runtime. Use the Condition, Name and Operator dropdowns to create the expressions for the display conditions. Only valid variables from the current Web Model are enabled in the Name dropdowns; however, you may also enter static values into these fields. If more than one condition is configured, you may chose to make all conditions required or make only one condition required by clicking one of the All conditions met or Any one condition met option buttons.
All required fields are specified.
For the Skyway Image Web Control, source images are loaded from the file system at design time. To reference a source image from another website, use the basic HTML image control (can be added in code view in the UI Editor).
Source images are loaded and stored by the Web Model at design time. At runtime, the Web Model does not access the source image from the local source location.
The skyway extension folder can be used to augment the Skyway deployments. One of the key uses for this folder is to place image and icon libraries that can be referenced using the getBaseUrl() JSP Method.
