Product Limitations

DynamicPDF Core Suite has several limitations, as listed here.

• Extracting text from a PDF created with character shaping may yield incorrect output.

• The HtmlArea does not support Javascript.

• HTML Form field elements are not retained as interactive elements, but are flattened when using HtmlArea.

• Content such as Flash, Java, and ActiveX coming from the Object tag are ignored in HtmlArea and a rectangle is drawn in place of the Object tag.

• The rights-enabled permission of an existing PDF document is not preserved after that document has been merged. The rights-enabled permission acts like a digital signature and any changes to the document will invalidate it. Since the rights-enabled permission is a proprietary feature of Adobe and not part of the PDF specification, Core Suite is unable to revalidate it and add it back to the document.

• DynamicPDF core suite does not support decrypting PDF documents that contain custom or unpublished algorithms (40-bit RC4 and 128-bit RC4, 128 -bit AES 256-bit AES are fully supported).

• Form flattening not supported for XFA PDFs.

• XFA form filling is supported only for static XFA forms with a fields entry.

• Text extraction skips characters that are more than 2 bytes.

Limitations of using NetStandard DLL.

• The BitmapImageData class cannot be used as it represents the image data created from System.Drawing.Bitmap.
• Constructors which use a System.Drawing.Bitmap (Ex: Creating an Image using Bitmap object) are not available.
• The CanLoadSystemFont(System.Drawing.Font font) and LoadSystemFont(System.Drawing.Font font) methods of Font class are not supported.
• The DrawToWeb method of the Document class is not supported.
