Retrieve Stringlist item into image (Stringlist class)
This method copies data from a specified Stringlist item to an image.
GetImage is a member of the Stringlist class.
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 been associated with the Stringlist with a BindImage method (BindImage (Stringlist function). 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 (Stringlist function) associates the image with the Stringlist, eliminating the need to specify the image name on the GetImage.
