Dear community
I try create one pdf file with text, which contain also space symbols.

I use the method XGrapics.DrawString. But by using of any fonts – the text in the pdf file is trimmed.
For example the text is "Aaaaa EG ggggggggggggggggggggg", but in pdf file I can see only „Aaaaa EG“

The text is trimmed if I use follows fonts

BaskervilleOldFace

LucidaFax
LucidaHandwriting

Hi!

I don't understand the problem. Some more information and some more code might help me to understand the problem.
What are "space symbols"?

Also „space symbol“ is symbol which entered with space key of keyboard.
Between words in texts are space symbols.
I have gived one string as example. „Aaaaa EG ggggggggggggggggggggg“
I make pdf file ONLY with this string.

Code:

double s = 12;
PdfSharp.Drawing.XFont f = new PdfSharp.Drawing.XFont("Swis721 Blk BT", s, PdfSharp.Drawing.XFontStyle.Regular, options0);
                
PdfSharp.Drawing.XRect rect = new PdfSharp.Drawing.XRect(new PdfSharp.Drawing.XPoint(200, 100), size);
xTextFormatter0.DrawString("Aaaaa EG ggggggggggggggggggggg", f, brush, rect);

With font family name "Swis721 Blk BT" (or with fonts from my list) I have pdf file with text
„Aaaaa EG“. Where is rest of text???

I tried "Lucida Fax" and it worked as expected.

Code:

XTextFormatter xTextFormatter0 = new XTextFormatter(gfx);
XPdfFontOptions options0 = new XPdfFontOptions(PdfFontEncoding.WinAnsi, PdfFontEmbedding.Always);
XSize size = new XSize(400, 400);
XBrush brush = XBrushes.Black;

double s = 12;
PdfSharp.Drawing.XFont f = new PdfSharp.Drawing.XFont("Lucida Fax", s, PdfSharp.Drawing.XFontStyle.Regular, options0);

PdfSharp.Drawing.XRect rect = new PdfSharp.Drawing.XRect(new PdfSharp.Drawing.XPoint(200, 100), size);
xTextFormatter0.DrawString("Aaaaa EG ggggggggggggggggggggg", f, brush, rect);

The four leading lines initialize objects that were missing in your code snippet.

Please provide an SSCCE if you think there is a bug in PDFsharp.

Now I understand where is problem. Namely I take size for rectangle by MeasureString

Code:

double s = 12;
PdfSharp.Drawing.XFont f = new PdfSharp.Drawing.XFont("Swis721 Blk BT", s, PdfSharp.Drawing.XFontStyle.Regular, options0);
PdfSharp.Drawing.XSize size = gfx.MeasureString("Aaaaa EG ggggggggggggggggggggg", f);


PdfSharp.Drawing.XRect rect = new PdfSharp.Drawing.XRect(new PdfSharp.Drawing.XPoint(200, 100), size);
xTextFormatter0.DrawString("Aaaaa EG ggggggggggggggggggggg", f, brush, rect);

Thank you for help

A note (for nav3000 and other readers here):
The XGraphics class (gfx object) has several DrawString methods that can be used if you do not need automatic line breaks.

The XTextFormatter class is a wrapper that supports line breaks, but internally it invokes gfx.DrawString().

You can skip the call to gfx.MeasureString() and call gfx.DrawString() directly, passing only a point (without size).
You should get the same result: text in one line - and if the text is too long it will continue across the page border.
