The upcoming QPL 9.14 Beta 2 will support justified text using TrueType subsetted fonts that also include foreign characters such as German and French characters with diacritics etc.

So my last option was to use AddStandardFont, but I found out that some letters with diacritics are missing in the resulting PDF file. I'm doomed.

Code snippet:
(I put it in a picture, because my browser didn't display the letters with diacritics correctly either.)

In summary:
- AddTrueTypeFont: Produces too big PDF files with embedded fonts.
- AddTrueTypeSubsettedFont: Justification of HTML text doesn't work.
- AddStandardFont: Offers only the few standard fonts. Also first line of text is shifted up and line spacing is smaller.

I'm starting to be a bit desperate here... Nevertheless, thank you both for your help. I hope this issue will be eventually resolved in Quick PDF library.

This code is working correctly

int ID = QP.AddStandardFont(8); // Standard Font = Times New Roman

QP.SetHTMLNormalFont("Default", ID);

double w = 180;

double ypos = 10;

QP.DrawBox(10, 0, w, 800, 0);

QP.DrawHTMLText(10.0, ypos, w, "

dddddddd ddddd dddd ddddd ddddd ddddd dddddddddddd

");

ypos += 180;

QP.SaveToFile("out.pdf");

I believe it is because the AddTrueTypeSubsettedFont is creating a Composite font and Composite fonts do not support the PDF WordSpacing operator that we are using to space the text out correctly. I will need to spend some time to see if I can work on a work-around for subsetted fonts but it the existing HTML code could require some fundamental changes for rendering justified text.

I did some more experiments with the PDF file created with your code (w = 200).

CREATING
When I create the file with QuickPDF DLL 9.11, 9.12 or 9.13, it doesn't change anything.

DISPLAYING
I tried to view the created file in Adobe, Foxit, Chrome and also with the Quick PDF Library application on the "PDF Preview" tab.

Justification is not displayed correctly in:
- Adobe Reader 10.1.6
- Foxit Reader 4.3.0.1110
- Google Chrome 25.0.1364.152
- Quick PDF Library application 9.11
- Quick PDF Library application 9.12

Justification is displayed correctly in:
- Quick PDF Library application 9.13

PRINTING
I tried to print the created file to printer with PrintDocument function from Quick PDF DLL.

Justification is not printed correctly with:
- Quick PDF DLL 9.11
- Quick PDF DLL 9.12

Justification is printed correctly with:
- Quick PDF DLL 9.13

I later realised that your measurements were in mm.

AddTrueTypeSubsettedFont - should be 0. I have a bad habit of using 1 thinking that it will embed the font - but that is what the function is doing anyway.

I also discovered the same behaviour with the various widths which is quite strange. I haven't been able to try down why it doesn't work as expected.

I will keep working on it but have many other cases I am working on at the same time.

edvoigt:
I reported the issue to Debenu.

AndrewC:
I tried your code and played a little with the values. I changed all the "ypos += 180;" to "ypos += 110;", because spaces between texts were too big. Then I changed width and discovered a strange behavior: Justification seems to work when the width is small (w = 150), but not with bigger widths (w = 200).
Width 150
Width 200

PS: Why did you use AddTrueTypeSubsettedFont with third parameter set to "1"? Documentation says it should be "0". (I tried both and it didn't affect the justification.)
AddTrueTypeSubsettedFont

PPS: I forgot to mention in my first post, that my values are in millimetres. Yours are in points. (I again tried both and it doesn't affect the justification, once you convert the values.)

Can you try the following code which will make it simpler to understand and debug.

QP.SetOrigin(1);

int ID = QP.AddTrueTypeSubsettedFont("Times New Roman", "abcd ", 1);

QP.SetHTMLNormalFont("Default", ID);

double w = 150;

double ypos = 10;

QP.DrawBox(10, 0, w, 800, 0);

QP.SetTextSpacing(-10);

QP.DrawHTMLText(10.0, ypos, w, "

aaaaaaaa aaaaa aaaa aaaaa aaaaa aaaaa aaaaaaaaaaaa

");

ypos += 180;

QP.DrawHTMLText(10.0, ypos, w, "

bbbbbbbb bbbbb bbbb bbbbb bbbbb bbbbb bbbbbbbbbbbb

");

ypos += 180;

QP.DrawHTMLText(10.0, ypos, w, "

cccccccc ccccc cccc ccccc ccccc ccccc cccccccccccc

");

ypos += 180;

QP.DrawHTMLText(10.0, ypos, w, "

dddddddd ddddd dddd ddddd ddddd ddddd dddddddddddd

");

ypos += 180;

QP.SaveToFile("out.pdf");

Process.Start("out.pdf");

Hi,

you are right. With Drawtext you have more to do (splitting as you assume), because you can't use text with different styles as a unit.

Sorry, I see no easy way. But you should the wrong working "justified" report as issue to Debenu.

DrawHTMLtext only works with "justified", not with "justify".
And I need DrawHTMLtext to draw text, which has different parts in different font styles (normal/bold/italic/underline). If I wanted to use DrawText, I would have to split the text and write each part separately, am I right?
