Guide Section: GUI of EASAPs / Diagramming | EASAP Tree: USER INTERFACE Branch / DIAGRAM LIST

IMAGE is used to display image files in the input region of a TABBED PANE or in the DIAGRAM region.

Currently, there are three file formats that can be imported into an EASAP, and they are:

• Graphics Interchange Format (.gif)
• JPEG Format (.jpg, .jpeg)
• Portable Network Graphics Format (.png)

Before an image file can be rendered in an EASAP’s user interface, the file must first be uploaded from its current location onto the EASA Server and into the appropriate EASAP folder. This uploading process is accomplished using either the Files selection under EASA→Author→Authoring menu or the Files Tab in EASAP Builder.

IMAGE
Under USER INTERFACE	Essential Parameters:
	Tool Tip:	Text to be displayed as a tool tip
	Chart Reference:	Select a CHART REFERENCE to display a chart extracted from an Excel spreadsheet
	Optional Parameters:
	Image:	Image file name (.gif, .jpg, .png)
	Show if:	Logical expression, if FALSE then image NOT shown else default→TRUE
	Tool Tip:	Text to be displayed as a tool tip
Under DIAGRAM	Essential Parameters:
	Origin:	Point coordinates of lower left corner of image: (ie. 0,0)
	Optional Parameters:
	Image from Action:	Select IMAGE EXCEL ACTION used to produce image
	Size:	Width and height of image in units of base length scale (meters) or in pixels
	Transform:	Select one or more transforms from list. Order selected is order applied.
	Define in Pixels:	Allows disabling of auto-fitting and retaining Size: in pixels (default→FALSE, TRUE)
	Image:	Image file name (.gif, .jpg, .png)
	Show if:	Logical expression, if FALSE then image NOT shown else default→TRUE
	Tool Tip:	Text to be displayed as a tool tip

All image files (.gif, .jpg, .png) have an existing width and height. If you want to maintain an images’s aspect ratio, you will need to know the existing width and height, and then set the IMAGE Size: parameter using width and height having an equivalent ratio.

If your imported images are being distorted unacceptably, set Define in Pixels: parameter to maintain the original resolution of the image file.

If an imported image is to be used in conjunction with a native DIAGRAM, then you will most likely have to specify the Origin: and Size: parameters using expressions containing the same object references used in the native object parameters.

Note: If you specify the size of an imported image in pixels, then all other DIAGRAM's need to be sized relative to the number of pixels in each direction.
