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.
- One way to extract a Stringlist item into an image (called
Headstone, below) is as follows:%list:getImage(%n, 'HEADSTONE')
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.
