The WR Area to picture command allows you to place the contents of the area referenced by area in a picture field or variable. Passing a 4D Write area to the WR Area to picture command returns a picture that can later be assigned to a picture field or a picture variable.
- If savedDoc equals 0, and the document has been modified since it was last saved, a dialog will be displayed asking the user if they wish to save the document.
- If savedDoc equals 1, the document will be considered as saved and the user will not be prompted to save it.
- If preview equals 0, no picture preview will be created.
- If preview equals 1, a picture preview will be created.
Note: If no picture preview is created, the picture cannot be displayed.
If optional parameters are omitted, the default settings for area will be applied.
