Check the nObjectcontinuationType parameter do determine whether you need to print the graphic. This is from VFP's help file for the Render() method.
-----
nObjectContinuationType
Indicates the current continuation state for the rendered element. When layout elements span pages, they are rendered in multiple sections (once for each page).
Note
Continuation can occur for layout elements of Expression (Field), Shape, or Line type. Although Labels and Pictures can span bands in a report, they cannot span pages and ReportListener renders them only once. Not all band types support spanning pages. Refer to Report Bands for more information.
The following table lists the possible values for nObjectContinuationType.
Value Continuation Type
0 Complete (no continuation).
1 Start of layout element occurrence, will not finish on the current page.
2 Mid-element, neither started nor finished on the current page.
3 End of element, completed on the current page.
