TIOParams.PDF_ImageOptions


Declaration

property PDF_ImageOptions: TIOPDFImageOptions


Description

Specifies options for saving of images to PDF.
Value Description
iepioShrinkOnly If not specified, all images will be made to fill the entire page. If specified, only large images are shrunk. Small images are not enlarged
iepioCentered Specifies that the image will be centered within the page

Notes:
- This property is only used when saving PDF files natively, e.g. using TImageEnIO.SaveToFilePDF or TImageEnMIO.SaveToFilePDF (and the PDFium PlugIn is disabled). It is NOT used when saving with PDFium or for layers
- If you are using a TIEMultiBitmap or TImageEnMView, you can use DuplicateCompressionInfo to propogate the parameter to all frames

Default: [] (all images are scaled and not centered)


Examples

// Dont' scale small images to size of page
ImageEnView1.IO.Params.PDF_ImageOptions := [iepioShrinkOnly];

// Save all pages to PDF (A4) with centered images (and no scaling of small images)
ImageEnMView1.MIO.Params[0].PDF_PaperSize := iepA4;
ImageEnMView1.MIO.Params[0].PDF_PageMargin := Round( 0.25 * 72 ); // 1/4 inch
ImageEnMView1.MIO.Params[0].PDF_ImageOptions := [iepioShrinkOnly, iepioCentered];
ImageEnMView1.MIO.DuplicateCompressionInfo(TRUE);
ImageEnMView1.MIO.SaveToFilePDF('d:\test.pdf');
