Hi All,
I am trying to work out a logic to determine when a text should be broken down. I am using the function FPDFTextObj_GetSpaceCharWidth to determine the width of the space character.

This approach generally appears to be work well. However, for some documents, the space width is zero for some of the text blocks. What could cause this?

Example
In the sample document the word "Forecasts" in the table header .

Thanks,
Sau

Hi,

I can not reproduce this on your example

Code:

static void Main(string[] args)
{
    PdfCommon.Initialize();
    var doc = PdfDocument.Load("e:\\0\\4\\macro_GS1.page21.pdf");
    for(int i = 0; i< doc.Pages[0].PageObjects.Count; i++)
    {
        if (!(doc.Pages[0].PageObjects[i] is PdfTextObject))
            continue;

        var txt = (doc.Pages[0].PageObjects[i] as PdfTextObject).TextUnicode;
        if (txt != "Our FX forecasts ")
            continue;
        float w;
        Pdfium.FPDFTextObj_GetSpaceCharWidth(doc.Pages[0].PageObjects[i].Handle, out w);
        Console.WriteLine(w);
    }
}


Code:

Press any key to continue . . .
