I would like to request an example of the RadPdfProcessing library utilizing a Line Chart similar to how the Bar Chart is drawn in this example. 

Additionally, it would be great if there was an example with multiple charts on one page.

Thank you!

I was working on some acroforms and wherever I needed a space I kept on getting a different letter (Ê). On debugging the problem seems to be in the TryGetCharCode function of OpenTypeFontSource

Version: 2019.3.917

Below is copy of function

public override bool TryGetCharCode(int unicode, out int charCode)
        {
            bool result = false;
            ushort glyphId;
            charCode = CMap.MISSING_GLYPH_ID;
            if (this.TryGetGlyphId(unicode, out glyphId))
            {
                ushort uCharCode = CMap.MISSING_GLYPH_ID;
                CMapTable table = this.CMap.GetCMapTable(3, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                table = this.CMap.GetCMapTable(1, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                charCode = uCharCode;

                return result;
            }

            return false;
        }

The font used has 2 cmap tables: one with platformid of 3 and encodingid of 1, the other with platformid 1 and encodingid 0. According to https://docs.microsoft.com/en-us/typography/opentype/spec/cmap platform id 3 and encoding 1 is correct for windows so not sure why the first call to getcmaptable looks for encodingid 0.

Second of all even if I change it to the following

CMapTable table = this.CMap.GetCMapTable(3, 1);

if there is a second cmap with platformid of 1 whatever the result of the call with regards to platformid 3, the result will be overridden

I can say that if I add some checks so that if the first call succeeds it doesn't attempt the 2nd I do get the expected behaviour in the pdf and get spaces

As a note the FontFamily property of the OpenTypeFontSource is "Arial"

I am using the trial version of telerik for xamarin for .net core which was released last year, to convert pdf to text. Our service is hosted in Azure. The text which I get back, in certain cases the spaces are missing (say for example instead of 'I [am] here', it displays 'I[am]here'. This happens randomly. 

The code which we have used is as follows -

A possible workaround could be to draw a rectangle around the desired Block.

RadFixedDocument document = new RadFixedDocument();
RadFixedPage page = document.Pages.AddPage();
page.Size = new Size(600, 800);
FixedContentEditor editor = new FixedContentEditor(page);
editor.Position.Translate(defaultLeftIndent, 50);

Block block = new Block();
block.InsertText("PDF");

editor.DrawBlock(block);

Block border = new Block();
border.GraphicProperties.StrokeColor = RgbColors.Black;
border.GraphicProperties.IsFilled = false;
border.GraphicProperties.IsStroked = true;
border.GraphicProperties.StrokeThickness = 1;
border.InsertRectangle(new System.Windows.Rect(block.Measure()));

editor.DrawBlock(border);

Telerik Pdf Processing Cannot open the attached pdf file and exception occur.

How do i slove it?

Code :
  RadFixedDocument document = new PdfFormatProvider().Import(input);

Exception Message :
   System.UriFormatException  無效的 URI: 無法剖析主機名稱。
