Examples

ImageEnMView1.MIO.DoPrintPreviewDialog();

// Display the Print Preview maximized
ImageEnMView1.MIO.PrintPreviewParams.DlgMaximized := True;
ImageEnMView1.MIO.DoPrintPreviewDialog('', false, 'Print Preview');

Compatibility Information

Prior to v8.0.0, if the user specified a width and height in the Preview dialog, it would not adjust the output to ensure the image aspect ratio was maintained (i.e. image may print stretched). With 8.0.0, the aspect ratio is maintained by default. To restore the older functionality, set ImageEnMView1.MIO.PrintingMaintainAR := False;
