RadPdfViewer can't load properly documents that contains many paths.

When exporting a RadFixedDocument, which contains a signature added with PdfProcessing a NotSupportedException is thrown: 'Stream does not support reading.'

The highlight annotation appears above the text and covers it, instead of appearing under it.

Expected:

Actual:

Exception when saving a document that is being used by another process

Hello 

 

I am have a problem with pdf wiewer when the PDF file contains an images , it is slow in movement and it is difficult to navigate between pages. Is it possible to fix this problem 

 

 

When there is no ToUnicode CMap, the text from the Simple Font instance should be extracted by mapping the glyph name to its corresponding charcode according to Adobe Glyph List. Additionally, the Differences array should be included in these calculations when there is custom encoding. The current implementation of RadPdfViewer makes ToString to the original char id byte value which leads to wrong characters. 

The default radio button state is not displayed correctly with specific documents

This is not a valid PDF scenario as having appearance state requires having multi-state appearances. However, we should handle this invalid document scenario on our side so that the app does not crash with NullReferenceException.

The CID font may define a description of the glyph widths. By specification, the widths can be defined in two ways - with start and end CID codes or with and an array of CID codes. However, the current implementation supports only CID arrays as direct property and not as an indirect object. This leads to incorrectly imported glyph widths and text positioning issues.

The offset of the CropBox is not respected and is always treated as 0.

Workaround: Import the document with PdfProcessing, change the CropBox offsets of the pages to 0, export the modified document and then import it in PdfViewer.

The EI keyword defines an operator for ending the image data. When the stream contains the same sequence, the parser treats that as an end of the image data. As a result, the image and the following content cannot be properly parsed and there is missing content when the document is visualized.

Some files when opened with PdfViewer will throw a KeyNotFoundException which will be handled. Parts of the text in the file might or might not be missing.

The exception is thrown during "Put" operator execution.

The editor size should be limited to the size of the widget. Currently on is able to enter more than one line in a textbox and when the content is not visible and it is cut off when flattening. 

It is actually checked and only the appearance is wrong. When the file is saved the checkboxes states are as expected.

Please refer to the attached gif file and notice the loading delay when scrolling to a specific page. It would be nice to optimize this experience.

Memory leaks when opening a large file several times.
