Hello. I make plug-in for inDesign 15

When I do export document to PDF I can use interface IPDFExportPrefs for set up export options, but I can't found same for exportProvaider  PNG - I need set option "export selected range" but it use last settings but do know how.

exportProvider->ExportToFile(pngFileId, _document, iSelectionManager, "PNG", kFullUI);
