After upgrade to 10.3- imported TIFFs are marked with 'evaluation only'

Aspose.PDF Product Family
1

Hi,



I upgraded Aspose.Pdf from 9.7 to 10.3, and after the upgrade, my imported tiff images in pdf show with a watermark:




Evaluation only

Created with Aspose.Imaging




Our Aspose.Pdf license is up to date (extended for another year of updates a month ago). All other Pdf features we use work just fine.



Is imaging a separate license in 10.3?

Hi Matt,


Thanks for your inquiry. Please note it seems you are using Aspose.Imaging in your code, please double check its license expiry. If you have a valid license then please share your sample code here and license via email as suggested here. We will look into it and guide you accordingly.

We are sorry for the inconvenience caused.

Best Regards,

Update:


It appears that only when Image.IsBlackAndWhite property is set to true (available only in v10), then the output images get the watermark. On the other hand, without it, the pdf would bloat the TIFF images in uncompressed mode.

Demo code:




public void ImageWatermarks( string pdfFile, int resolution )

{

new License().SetLicense( “Aspose.Pdf.lic” );



// extract page images to streams

var doc = new Aspose.Pdf.Document( pdfFile );

var res = new Aspose.Pdf.Devices.Resolution( 300 );

var pageImageStreams = doc.Pages.Cast<Aspose.Pdf.Page>()

.Select((p, i) =>

{

var tiffSettings = new TiffSettings { Compression = CompressionType.CCITT4, Depth = ColorDepth.Format1bpp };

var tiffDevice = new Aspose.Pdf.Devices.TiffDevice(PageSize.PageLetter, res, tiffSettings);

var stream = new MemoryStream();

tiffDevice.Process( doc, i + 1, i + 1, stream );

stream.Position = 0;

return stream;

});



// insert image streams into new document, one image stream per page

var imagePagesDoc = new Aspose.Pdf.Document();

foreach (var imgStream in pageImageStreams)

{

var page = imagePagesDoc.Pages.Add();

page.PageInfo.Margin.Bottom = 0;

page.PageInfo.Margin.Top = 0;

page.PageInfo.Margin.Left = 0;

page.PageInfo.Margin.Right = 0;

page.PageInfo.Height = Aspose.Pdf.PageSize.PageLetter.Height;

page.PageInfo.Width = Aspose.Pdf.PageSize.PageLetter.Width;



var image = new Aspose.Pdf.Image

{

ImageStream = imgStream,

// the only way to ensure/force compression… ; only in v10.3

// When set to true, image in the document appears with ‘evaluation’ watermark

IsBlackWhite = true

};

page.Paragraphs.Add(image);

}



imagePagesDoc.Save( pdfFile + “.images.pdf” );

}

Hi Matt,

Thanks for sharing the details.

I have tested the scenario and I am able to reproduce the same problem that an evaluation watermark appears in the resultant PDF when converting Image to PDF and we have set the value of IsBlackWhite to true. For the sake of correction, I have logged it in our issue tracking system as PDFNET-38522. We will investigate this issue in detail and will keep you updated on the status of a correction.

We apologize for your inconvenience.
