I download trail version 0914.

found 2 problems.

1. not support Chinese for function DrawText.

2. for function SetFillColorCMYK,

QP.SetFillColorCMYK(100,0,0,0) and QP.SetFillColorCMYK(50,0,0,0)

shows no different , it looks same on pdf.

Is it right, trail version does not support full function？

Hi Mitchell!

The trial version is only limited in time - not in functionality.

For your problem you should use the search function here

'cause there were similar posts in the past.

Cheers and welcome here,

Ingo

Do the Advanced search and change time settings.

charset ... japanese ... japanese support ... unicode ... codepage ...

spread your mind ;-)

Using chinese font it's not enough simply using the drawing functions.

You have to add your font for example.

Hi Ingo:

Just do the Advanced search, found some answer and bring more question !!! Ha! Ha!

1.AddSubsettedFont function can show Chinse words, but the function parameters squences is different Delphi and

Debenu Quick PDF library 9.14 Referece Guide.pdf,

Delphi xe2 : FontName:system.widestring

SubSetChars:system.WideString

Options:System.Integer

Referce Guide : AddSubsettedFont(FontName: WideString;

CharsetIndex: Integer;

SubsetChars: WideString): Integer;

the other strnage thing is no matter how to chnage FontName ( same as the name in C:\Windows\Fonts\), the Chinese

Word font only shows default font : '新細明體標準' and the font id always same as 1476395012.

Why?

Code:

//ifontID2 := QP.AddTrueTypeSubsettedFont('新細明體標準', '胡明元', 7);

//ifontID2 := QP.AddTrueTypeSubsettedFont('MS Gothic', '胡明元', 7);

//ifontID2 := QP.AddTrueTypeSubsettedFont('微軟正黑體', '胡明元', 7);

ifontID2 := QP.AddTrueTypeSubsettedFont('胡明元', 7);

//CharsetIndex 7: Chinese Big 5

if (QP.SelectFont(ifontID2) = 1) then

begin

QP.SetTextColorCMYK(100, 0, 0, 0);

QP.SetTextSize(24);

QP.DrawText(30, 30, '胡明元');

end;

2.about CMYK color question, still found nothing!!!

QP.SetFillColorCMYK(100,0,0,0) ===> Blue

QP.SetFillColorCMYK(50,0,0,0) ===> Light Blue

But the second one will show Blue color same as first one!

Why?

Code:

QP.SetFillColorCMYK(100,0,0,0)

QP.DrawBox( 10, 10, 10, 5, 2);

QP.SetFillColorCMYK(50,0,0,0)

QP.DrawBox( 30, 10, 10, 5, 2);

3. I want to DrawText(10,10,'CMYK')

letter 'C' set color to CMYK(100,0,0,0);

letter 'M' set color to CMYK(0,100,0,0);

letter 'Y' set color to CMYK(0,0,100,0);

letter 'K' set color to CMYK(0,0,0,100);

is there a function can extact a letter form text and set it's color?

Thanks

Mitchell Hu

for the point 2. I got answer:

the value for CMYK should be divided by 100.

QP.SetFillColorCMYK(100/100,0,0,0) ===> Blue

QP.SetFillColorCMYK(50/100,0,0,0) ===> Light Blue

the 3 point:

use function TDebenuPDFLibrary0914.GetTextWidth(Text: WideString): Double

code

ifontID2 := QP.AddTrueTypeSubsettedFont('標楷體標準','胡明元', 7);

if (QP.SelectFont(ifontID2) = 1) then

begin

QP.SetTextColorCMYK(100, 0, 0, 0);

QP.SetTextSize(48);

QP.DrawText(30, 30, '胡明元');

QP.SetTextColorCMYK(100, 0, 0, 0);

QP.SetTextSize(48);

QP.DrawText(100, 30, '胡明元');

QP.SetTextColorCMYK(0, 100, 0, 0);

QP.DrawText(100+QP.GetTextWidth('胡明元'),30,'胡');

QP.SetTextColorCMYK(0, 0, 100, 0);

QP.DrawText(100+QP.GetTextWidth('胡明元胡'),30,'明');

QP.SetTextColorCMYK(0, 0, 0, 100);

QP.DrawText(100+QP.GetTextWidth('胡明元胡明'),30,'元');

end;
