Exporting Reports with QuickReport
The advice here is applicable to all profesional versions later that QR3.62, unless
otherwise indicated.
Available formats
these export text, images and graphics.
TQRPDFDocumentFilter -> HTML ( unit QRPDFFilt.pas)
TQRHTMLDocumentFilter -> HTML ( unit QRWebFilt.pas)
TQRXMLSDocumentFilter -> XML ( unit QRXMLSFilt.pas)
Other (text only) filters in unit QRExport.pas.
TQRWMFExportFilter -> Windows metafile
TQRCommaSeparatedFilter -> CSV
TQRXLSFilter -> XL
TQRRTFExportFilter -> richtext
TQRAsciiExportFilter ->
Using the export components
Exporting may be performed from the standard preview using the ‘Save’ button. If an export component is placed on the report form, the corresponding option will be added to the save file dialog. This defaults to ‘QRP’ except in QR5 where the default export fromat may be set using the ‘PreviewDefaultSaveType’ option of the report.
Exporting from code
The principle is the same for all the document filters. [Note that the document filter is not the corresponding component on the tool palette. These are not used for exports in code.]
uses ;
var
aExpFilt : ;
begin
aExpFilt := .Create();
// Set any relevant properties
aExpFilt. := ;
// perform the export
repForm.Quickrep1.ExportToFilter( aExpFilt );
// clean up
aExpFilt.Free;
end;
Examples
1. PDF to file
uses QRPDFFilt;
var
aPDF : TQRPDFDocumentFilter;
begin
aPDF := TQRPDFDocumentFilter.Create(‘report.pdf’);
aPDF.FontHandling := fhAutoEmbed;
repform.QuickRep1.ExportToFilter( aPDF);
aPDF.Free;
end;
2. PDF to Stream
var
aPDF : TQRPDFDocumentFilter;
tmplist : TStringlist;
begin
tmplist := TStringlist.Create;
// omitting the file name means the report is streamed
aPDF := TQRPDFDocumentFilter.Create(”);
aPDF.FontHandling := fhAutoEmbed;
repform.QuickRep1.ExportToFilter( aPDF);
// catch the PDF stream in a list
apdf.Stream.Position := 0;
tmplist.LoadFromStream(aPDF.Stream);
tmplist.SaveToFile(‘pdf from stream.pdf’);
aPDF.Free;
tmplist.free;
end;
The same code may in princple be used with any filter except WMF.
3. WMF ( Windows metafile).
The WMF export filter works differently than the other filters. The other export filters render the report using the filter. The WMF filter takes the pages rendered to the preview and saves each page as a metafile. To use this filter outside of the preview, you have to render the report first using Prepare.
var
aWMFFilt : QRWMFExportFilter;
begin
TQRWMFExportFilter.Create(‘c:reports’)
quickrep1.Prepare;
quickrep1.qrprinter.ExportToFilter(aWMFFilt);
quickrep1.qrprinter.Free;
quickrep1.qrprinter := nil;
Please note that the file name extension is picked by the Enhanced property to the export filter. EMF if it’s True, WMF if it’s false.
