Hi

1. After your call to MIO.Acquire, use MIO.SaveToFilePDF

2. ImageEn outputs the images to your PDF at their current size. You may want to resample them to a smaller size:

Also, check your PDF_Compression:

Hello:
Thanks.I test with the code as bellow:

ImageEnMView1.MIO.Acquire;
ImageEnMView1.Proc.Resample(100, 100, rfLanczos3, True);
ImageEnMView1.MIO.Params[0].PDF_Compression := ioPDF_G4FAX;
ImageEnMView1.MIO.SaveToFile('d:\test.pdf');

1.The image is not clear and blurred
2.The generated PDF document is still large,two pages,about 11MB

Hi

1. 100x100 pixels is very small. You want at least 1000x1000.

2. ImageEnMView1.Proc.Resample only resamples the selected frame.

You want to resample all frames, e.g.

ImageEnMView1.MIO.Acquire;
ImageEnMView1.MBitmap.ResampleAll( 0.25, rfFastLinear );
ImageEnMView1.MIO.Params[0].PDF_Compression := ioPDF_G4FAX;
ImageEnMView1.MIO.SaveToFile('d:\test.pdf');
