Support for exporting WMF (Windows Metafile) and EMF (Enhanced Metafile) images should be implemented.

Workaround: Convert the WMF images to PNG before exporting:
ImageSource imageSource = new ImageSource(new MemoryStream(this.ConvertWmfImageToPng(stream)));
document.Pages.AddPage().Content.AddImage(imageSource);
...
private byte[] ConvertWmfImageToPng(Stream wmfImageStream)
{
    byte[] pngBytes;
 
    using (MemoryStream pngImageStream = new MemoryStream())
    {
        System.Drawing.Image imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);
        imageDrawing.Save(pngImageStream, System.Drawing.Imaging.ImageFormat.Png);
        pngBytes = pngImageStream.ToArray();
    }
 
    return pngBytes;
}

These permissions are defined on a document level and apply permission handlers. The permission handlers are similar to the security handlers but do not require the document to be encrypted. They are also used to determine which objects are to be included in the digest calculation used for the digital signature functionality.

We would like to search a PDF document for specific text and returns its position. We generate PDF reports using Telerik Reporting which contain placeholders that are replaced with images and text at run-time. It appears the logic has already been implemented, but the implementing classes (e.g., TextSearch, TextRecognizer) aren't accessible. Please consider making this capability available.

Hello Telerik,

Last time we attempted this the <Viewbox> contents would not render and were empty upon xaml to pdf output. It would be great if you had this feature and we could move completely away from raster output to PDF for controls that contain Viewboxes. Otherwise we have really liked the PDF's created by the tool, the vector output is sharp as expected.

Thank you,

Patrick

Currently Type0Font class has CMap that can only be Identity-H. The Identity-V is a vertical version of Identity−H. The mapping is the same as for Identity−H.

Release LIB 2021.2.531 (31/05/2021)

When the document contains Simple Font with predefined encoding and no ToUnicode mapping the text should be extracted with the following algorithm:

  • Map the character code to a character name according to the font’s Differences array.
  • Look up the character name in the Adobe Glyph List to obtain the corresponding Unicode value. 

Currently, the PdfProcessing library doesn't map the character code properly which leads to wrongly encoded text content.

Provide support for exporting type3 fonts

Last Updated: 07 Sep 2021 11:12 by ADMIN

When a document containing a SignatureField is exported with the IsEncrypted property set to true, a not set UserPassword is required to open it, which makes it impossible to be opened. An InvalidOperationException is thrown with the message "Password is not correct." when importing with PdfProcessing; Adobe Acrobat also doesn't recognize the password.

Workaround: Exporting with AES256 encryption does not have this problem:

provider.ExportSettings = new PdfExportSettings
{
	IsEncrypted = true,
	EncryptionType = EncryptionType.AES256
};
