When merging files that contain the "159 '\u009f'" char, ArgumentException("The encoding is not supported.") is thrown.
Trying to clone the Signature of a SignatureField leads to InvalidOperationException as the FieldName of the cloned signature is already set.
When a TrueType font is defined, the mapping of character codes to glyph indices depends on the built-in cmap table mappings defined in the font and the Encoding property defined in the PDF dictionary.
However, the current implementation maps all characters with cmap tables for Microsoft Symbolic and Macintosh Roman, which causes incorrect mapping results, e.g. space characters are mapped to an Ê glyph.
The issue is also described in the following public item: TryGetCharCode for OpenTypeFont uses wrong cmap and returns wrong charcode.
Workaround: Change the font of the TextBoxField's widget appearance:
foreach (var widget in field.Widgets)
widget.TextProperties.Font = FontsRepository.Helvetica;
When creating a GradientStop, an alpha channel of the color could be applied. However, this setting is not respected it the result document and the gradient is with full opacity. Steps to reproduce: 1. Create a gradient with an alpha channel: RadFixedDocument document = new RadFixedDocument(); RadFixedPage page = document.Pages.AddPage(); FixedContentEditor containerEditor = new FixedContentEditor(page); LinearGradient linearGradient = new LinearGradient(new Point(0, 0), new Point(30, 30)); linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 207, 0), 0)); linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 102, 204), 1)); containerEditor.GraphicProperties.FillColor = linearGradient; containerEditor.DrawRectangle(new Rect(10, 10, 48, 29)); 2. Export the document to PDF Observed: The alpha channel is not respected and the gradient is with full opacity
When opened in Adobe Reader it says that the file "claims compliance". However, when verifying the compliance with some validation tools there seem to be some issues mainly related but not limited to fonts.
