Re: [Podofo-users] font metrics StringWidth() differs from actually width of drawn string
Hey,
the version is 0.9.4 sorry, i just assumed that if not said specifically
everybody would default to the latest release :-)
Thank you for your answer. I will take a look at PdfEncodingFactory. In
another program that uses 0.9.3 PoDoFo it works fine with the posted
code. no monospace, no problems.
greetings
Dennis

Hi,
I wouldn't be surprised if it's due to the PdfIdentityEncoding() use
(which you actually leak; consider using PdfEncodingFactory members).
double imposedPdf::measureText(const wchar_t* text) {
PoDoFo::PdfString pdfText(text);
Another thing, at least from my past experience, when using wchar_t and
PdfString, I'd rather use PdfString::setFromWchar_t() method, to make
sure the value is wchar_t, not any other PdfString() constructor. It
depends on the actual system for which you compile, though.
By the way, mentioning your PoDoFo version would be also a good idea.
Bye,
zyx

[Podofo-users] font metrics StringWidth() differs from actually width of drawn string
Hey all!
I am trying to align a multiline text properly. Therefore i create my
font like this and set it to my painter:
font = g_outputDoc->CreateFont(fontName, isBold, isItalic, false,
new PdfIdentityEncoding(0, 0x, true), true);
font->SetFontSize(fontSize);
g_painter.SetFont(font);
After that i measure the text width of every line of the text i want to
draw like this:
double imposedPdf::measureText(const wchar_t* text) {
PoDoFo::PdfString pdfText(text);
return g_painter.GetFont()->GetFontMetrics()->StringWidth(pdfText);
}
(the pdf string constructor is used because if found something in the
mail archive which suggested that this is better...)
It returns a reasonable value (for example "11" is double the width of
"1" etc.)
My program will then draw text to a specific position like this:
PoDoFo::PdfRect textRect(mmToPdfUnits(x), mmToPdfUnits(y),
mmToPdfUnits(width), mmToPdfUnits(height));
PoDoFo::PdfString pdfText(text);
g_painter.DrawMultiLineText(
textRect,
pdfText,
textAlign,
vertiAlign,
false);
This results in the text being in the pdf with the corret font/fontsize,
BUT it is monospaced and its therefore wider then the suggested value of
the "StringWidth" function.
So in the end my texts placement is wrong, because i calculated the
placement depending on the widest line of the text i want to draw...
Any ideas why my fonts are all drawn monospaced? (and no: i didnt just
use monospaced fonts :D i tried about 50 different fonts, all with the
same issue)

Dennis Voss
