Retrieve Stringlist item into image (Stringlist class)


This method copies data from a specified Stringlist item to an image.

Syntax

sl:GetImage( itemNum, [imageName])

Syntax terms

sl A Stringlist object.
itemNum The number of the item in the Stringlist.
imageName A string that contains the name of an image. This is an optional argument if an image has already been associated with the Stringlist via BindImage. Otherwise, it is a required argument. This argument is case sensitive. That is, in the likely event the User Language was written in mixed case, with automatic uppercasing in effect (see [[Mixed-case User Language]]) the image name should be in uppercase.

Usage notes

  • All errors in GetImage result in request cancellation.

Examples

  1. One way to extract a Stringlist item into an image (called Headstone, below) is as follows:

    %list:getImage(%n, 'HEADSTONE')

  2. Here is a neater and more efficient way of doing this:

    %list:bindImage('HEADSTONE') ... %list:getImage(%n)

    In this last example, the BindImage associates the image with the Stringlist, eliminating the need to specify the image name on the GetImage.
