Dear Sir / Madam,
how to set pdf text
PdfMemDocument doc("D:\\sample pdf\\test.pdf");
PdfPainter painter;
PdfPage* pPage;
PdfRect rect;
PdfFont* pFont = doc.CreateFont("Times New Roman", new
PdfIdentityEncoding(0, 0xffff, true));
int i;
for (i = 0; i<doc.GetPageCount(); i++)
{
pPage = doc.GetPage(i);
if (!pPage)
PODOFO_RAISE_ERROR(ePdfError_InvalidHandle);
PdfExtGState gstate(&doc);
rect = pPage->GetPageSize();
painter.SetPage(pPage);
gstate.SetFillOpacity(0.5);
gstate.SetRenderingIntent(ePdfRenderingIntent_Saturation);
gstate.SetBlendMode(ePdfBlendMode_Darken);
painter.SetExtGState(&gstate);
painter.Save();
painter.SetStrokingColor(1.0, 0.0, 0.0);
painter.SetStrokeWidth(5);
painter.Rectangle(rect.GetWidth() - 205, rect.GetHeight()
- 55, 200, 50, 10, 10);
painter.DrawLine(0.0, 0.0, rect.GetWidth(),
rect.GetHeight());
//painter.SetTransformationMatrix(0.707, 0.707, -0.707,
0.707, rect.GetWidth()/3.0, rect.GetHeight()/2.0);
// First the transport.
painter.SetTransformationMatrix(1, 0, 0, 1,
rect.GetWidth() / 3.0, rect.GetHeight() / 2.0);
// Second make angles.
painter.SetTransformationMatrix(0.707, 0.707, -0.707,
0.707, 0, 0);
// Third make scale.
//painter.SetTransformationMatrix(100, 0, 0, 100, 0, 0);
PdfString text(L"hello");
painter.Restore();
painter.FinishPage();
}
doc.Write("D:\\sample pdf\\test2.pdf");
"hello" not appear in pdf, where is wrong?
if copy from https://sourceforge.net/p/podofo/mailman/message/30762385/
symbol appear, not text "hello".
if change to doc.CreateFont("Arial", new PdfIdentityEncoding(0, 0xffff,
true)) also same
PdfMemDocument doc("D:\\sample pdf\\test.pdf");
PdfPainter painter;
PdfPage* pPage;
PdfRect rect;
PdfFont* pFont = doc.CreateFont("Times New Roman", new
PdfIdentityEncoding(0, 0xffff, true));
pFont->SetFontSize(72);
for (int i = 0; i<doc.GetPageCount(); i++)
{
pPage = doc.GetPage(i);
if (!pPage)
PODOFO_RAISE_ERROR(ePdfError_InvalidHandle);
rect = pPage->GetPageSize();
//Draw simple shapes.
painter.SetPage(pPage);
painter.SetStrokingColor(1.0, 0.0, 0.0);
painter.SetStrokeWidth(5);
painter.Rectangle(rect.GetWidth() - 205, rect.GetHeight()
- 55, 200, 50, 10, 10);
painter.DrawLine(0.0, 0.0, rect.GetWidth(),
rect.GetHeight());
//Draw text as watermark.
painter.SetFont(pFont);
painter.SetColor(PdfColor(1.0, 0, 0));
PdfExtGState gstate(&doc);
//gstate.SetFillOpacity(1.0f * i / doc.GetPageCount());
gstate.SetFillOpacity(0.5);
gstate.SetRenderingIntent(ePdfRenderingIntent_Saturation);
gstate.SetBlendMode(ePdfBlendMode_Darken);
painter.SetExtGState(&gstate);
painter.Save();
painter.SetTransformationMatrix(1, 0, 0, 1,
rect.GetWidth() / 2, rect.GetHeight() / 2); // First
the transport.
painter.SetTransformationMatrix(0.707, 0.707, -0.707,
0.707, 0, 0); //
Second make angles.
//painter.SetTransformationMatrix(100, 0, 0, 100, 0, 0);
// Third make
scale.
// add text watermark here in Japanese
PdfString text(L"こんにちは");
// add text watermark here in Chinese
//PdfString text(L"?好");
// add text watermark here in English.
//PdfString text(L"Hello");
painter.DrawText(0, 0, text);
painter.Restore();
painter.FinishPage();
painter.SetPage(pPage);
painter.FinishPage();
}
doc.Write("D:\\sample pdf\\test2.pdf");
the symbol also very small.
if Japanese, try using "MS Mincho Regular"
no text or symbol display.
Please advice.
Thanks you very much.
With Regards,
Tang
