I scanned an A4 document at 200dpi in TIF format. I want to print it in its original size.
I set all print margins to zero. The printed image in "normal" mode is much smaller.
The printed image in "fit" or "stretch" mode is 5% smaller.
I inserted the scanned image in a "Openoffice writer" document and the borderless printing is exactly like the original.
How can I print the image in original size with ImageEn components?

Best Regards

Please make sure the image DPI is actually 200. Just for test, try this:

ImageEnView.IO.Params.DPI := 200;
ImageEnView.IO.DoPrintPreviewDialog();

I used the ImageEnMView component for scanning multipage document at 200 dpi and after I assign the selected page to ImageEnView component with this code:
ImageEnView1.Assign( ImageEnMView1.Bitmap).

following code:
ImageEnView.IO.Params.DPI := 200;
ImageEnView.IO.DoPrintPreviewDialog();
works because ImageEnView.IO.Params.DPI was at 300

but
ImageEnMView.MIO.Params[0].DPI := 200;
ImageEnMView.MIO.DoPrintPreviewDialog();
doesn't work because ImageEnMView.MIO.Params[0].DPI was alredy at 200.

What is the best way to assign the selected image to ImageEnView control, so as to keep also the dpix, dpiy and IO.params.dpi properties?

How can I solve the problem of printing from the ImageEnMView Control?

Thanks

You can try this:
procedure TForm1.ImageEnMView1ImageSelect(Sender: TObject; idx: Integer);
begin
 ImageEnView1.IEBitmap.Assign(ImageEnMView1.GetTIEBitmap(idx));
 ImageEnMView1.ReleaseBitmap(idx);
 ImageEnView1.IO.Params.Assign(ImageEnMView1.MIO.Params[idx]);
 ImageEnView1.Update;
end;

Thanks. My problem now is the printing from the ImageEnMView Control.

This code:
ImageEnMView.MIO.Params[0].DPI := 200;
ImageEnMView.MIO.DoPrintPreviewDialog();
doesn't work because ImageEnMView.MIO.Params[0].DPI was alredy at 200.

I found the problems in the ieprnform3.pas:

1) in the event "PrintPreview" the "ie.io.Params.DpiX" and "ie.io.Params.DpiY" settings are missing.

2) in the procedure "SetLanguage" the size combobox is not localized and grpMargins.Caption is set with "iemsg(IEMSG_INCHES, l)" only, I use cm.

I sent you the new ieprnform3.pas with this bug fixed.

Fix your code for new release and set the new versions to bpl please.

Best Regards

// Set the language
// unit hyiedefs
Type TMsgLanguage=(msSystem, msEnglish, msItalian, msGerman, msSpanish, msFrench, msPortuguese, msGreek, msRussian, msDutch, msSwedish, msPolish, msJapanese, msCzech, msFinnish, msFarsi, msChinese, msChineseTraditional, msDanish, msTurkish, msKorean, msHungarian, msUser);
ImageEnMView.MIO.MsgLanguage := msItalian;

// Change to CM
ImageEnView.MIO.DialogsMeasureUnit := ieduCm;
ImageEnView.MIO.DoPrintPreviewDialog('');

w2m, your solution is valid for ImageEnView controls.
ImageEnMView control use ieprnform3.pas. It has the bugs.
