[kyotsai]

Hi team

I need to convert exist pdf to image
this exist pdf has three pages
but after convert to JPEG
there have some display promblems in the third JPEG
the Chinese Traditional word display have problems in the third JPEG
but first,second page display Chinese Traditional word is good

How do I solve it???

I try to change the font
below is my code

Spire.Pdf.PdfDocument pdfsrc = new PdfDocument(fileInfo.FullName);
PdfUsedFont[] fonts = pdfsrc.UsedFonts;
Font font1 = new Font("Arial Unicode MS", 11f);
PdfTrueTypeFont trueTypeFont = new PdfTrueTypeFont(font1, true);
foreach (PdfUsedFont font in fonts)
{
font.Replace(trueTypeFont);
}

for (int i = 0; i < pdfsrc.Pages.Count; i++)
{
sDestFilePathTemp = string.Format("{0}_{1}.jpg", fileInfoOut.FullName, i + 1);
Image img = pdfsrc.SaveAsImage(i);
img.Save(sDestFilePathTemp, System.Drawing.Imaging.ImageFormat.Jpeg);
}

I get exception
The font being replaced is not a standard font of Type 1 font or a non-embeded TrueType font

I find it happend to change MingLiU font

I use spire.pdf 5.3.2 from Nuget
(packages\Spire.PDF.5.3.2\lib\net46\Spire.Pdf.dll)

Spire.Pdf.dll version is 5.3.2.2046

How do I solve it??

Hello,

Thank you for contacting us.
I did notice the display problems in the third generated JPEG and have submitted it to our Dev team for further investigating and fixing, if there is any update, we will let you know. Sorry for the inconvenience caused. Besides, after the analysis of your PDF, we found there is an embeded font like the attached screenshot shows. Please kindly note that the embeded font can not be replaced. Thus, you got the exception.

Hi team

any update?

Hello,

Thanks for your reply.
Sorry the issue hasn't been resolved yet. I learned from our Dev team that this issue is related the glyphs recognition. When converting PDF to images, it needs to determine which characters exist on the PDF page. This is achieved by recognizing the glyphs. However, when recognizing the glyphs of your PDF file, some characters were recognized incorrectly. This caused the issue. Our Dev team would keep looking for solutions. Once there is any good news, we will keep you informed. Thanks for your understanding.

Hello,

Thanks for your patience.
Glad to inform you that the reported issue has been resolved with our asian version. We prepared a temporary version (spire.pdf-asian_6.6.2.zip) for you. Please download and refer to the following sample code to test it firstly.

Code: Select all

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(@"AML_SPF_Daily_20190104163229.pdf");
List<Image> ListImage = new List<Image>();
for (int i = 0; i < doc.Pages.Count; i++)
//set true for Asia font
{ ListImage.Add(doc.SaveAsImage(i,true)); }
if (ListImage.Count > 0)
{
    for (int i = 0; i < ListImage.Count; i++)

    { Image image = ListImage[i]; image.Save(@"image" + (i + 1).ToString() + ".png", System.Drawing.Imaging.ImageFormat.Png); }
}
