How to output Chinese (Simplified)?

With the following,

int docID = qp.NewDocument();

int ttfID = qp.AddTrueTypeFont("Arial Unicode MS [Italic]", 0);

qp.SelectFont(ttfID);

qp.SetTextSize(10.0);

double pageTop = qp.GetPageBox(2, 1);

double textHeight = qp.GetTextHeight();

qp.DrawText(10, pageTop - (textHeight * 1) - 5, "... a day in the life");

qp.DrawText(10, pageTop - (textHeight * 2) - 5, "... 生活中的一天");

qp.SaveToFile(savePath + "test.pdf");

qp.RemoveDocument(docID);

Text in PDF output:

... a day in the life

...

With the following,

int docID = qp.NewDocument();

int ttfID = qp.AddTrueTypeFont("Arial Unicode MS [Italic] {936}", 0);

qp.SelectFont(ttfID);

qp.SetTextSize(10.0);

double pageTop = qp.GetPageBox(2, 1);

double textHeight = qp.GetTextHeight();

qp.DrawText(10, pageTop - (textHeight * 1) - 5, "... a day in the life");

qp.DrawText(10, pageTop - (textHeight * 2) - 5, "... 生活中的一天");

qp.SaveToFile(savePath + "test.pdf");

qp.RemoveDocument(docID);

Text in PDF output (none):

The text in the DrawText calls was copy/pasted from Google translate - English -> Chinese (Simplified).

Which version of Quick PDF Library are you using ? 7.xx or 8.xx ?

In 8.xx we changed all the internal strings in the library to Unicode so it is not possible to send a DBCS encoded string to the 8.xx version of QPL. For this reason we have recently deprecated the support of the following code pages from QPL 8.xx. Adding CJK fonts works correctly in 8.xx if you use the QPL.AddTrueTypeSubsetFont

Andrew.

No longer supported in QPL 8.xx
=======================================
932 (Japanese Shift-JIS)
936 (Simplified Chinese GBK)
949 (Korean)
950 (Traditional Chinese Big5)

int ifontID2 = QP.AddTrueTypeSubsettedFont("MS Gothic", "こんにちは", 0);
if (QP.SelectFont(ifontID2) == 1)
{
  QP.DrawTextBox(30, QP.PageHeight() - 60, QP.GetTextWidth("こんにち    は"), QP.GetTextHeight(), "こんにちは", 0);
}

Hi Andrew,

Thanks for the clarification and quick response!

I'm using QPL 8.16. I was a bit confused on the 'Add*SubSettedFont' functions usage. Also, I did experiment a bit with the AddCJK function (even though reference states only 'Japanese "HeiseiKakuGo-W5" font is currently supported.) When I loaded the generated PDF, Acrobat Reader informed me that I needed a font package to display the document and offered a link to the Adobe site download location.

NOTE : This forum doesn't display Unicode text very well and converts it to the jumble of characters in the previous messages. These strings are meant to be human readable UNICODE strings with native CJK characters.

QP.AddTrueTypeSubsettedFont("MS Gothic", "ã“ã‚“ã«ã¡ã¯", 0);

We are slowly improving the Asian font support and more work will be done in 9.12 and 9.13. 9.11 now has support for rendering vertical Asian text from existing PDF files.

AddTrueTypeSubsettedFont works pretty well with most fonts these days and is a pretty reliable method that add Asian fonts to a PDF.
