GET PICTURE FROM LIBRARY 


 

GET PICTURE FROM LIBRARY ( picRef | picName ; picture ) 
Parameter Type   Description
picRef | picName  Longint, String in Reference number of Picture Library graphic or Name of Picture Library graphic
picture  Picture variable in Picture from the Picture Library

The GET PICTURE FROM LIBRARY command returns in the picture parameter the Picture Library graphic whose reference number is passed in picRef or whose name is passed in picName.

If there is no picture with that reference number or name, GET PICTURE FROM LIBRARY leaves picture unchanged.

The following example returns in vgMyPicture the picture whose reference number is stored in the local variable $vlPicRef:

 GET PICTURE FROM LIBRARY($vlPicRef;vgMyPicture)

The following example returns in $DDcom_Prot_MyPicture the picture with the name "DDcom_Prot_Button1" stored in the Picture Library:

 GET PICTURE FROM LIBRARY("DDcom_Prot_Button1";$DDcom_Prot_MyPicture)

See the third example for the command PICTURE LIBRARY LIST.

If the Picture Library exists, the OK variable is set to 1. Otherwise, OK is set to zero.

If there is not enough memory to return the picture, an error -108 is generated. You can catch this error using an error-handling method.
