[Johnston]

Hi
I downloaded the Spire.PDF (Free version 3.8.173.5040 ) , Then I create an application( c# ).
The function is convert PDF file to mage file (.jpg).
But I found , If the PDF file contains a high-resolution image, after the conversion, it disappears !
It is a bug ?
How should I fix it ?
............................source code as below:
static void Main(string[] args)
{
var doc = new PdfDocument();
doc.LoadFromFile(@args[0]);

var dx = doc.SaveAsImage(0, 150, 150);
dx.Save(@args[1] + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
}

Dear Johnston,

After investigation, we found the font of the watermark is special, and here is a version can solve the issue. Please download the version from following link.
http://www.e-iceblue.com/downloads/Temp ... .8.131.zip

In addition, you need to put the Spire.FontType.dll in Debug folder and reference the other two dlls into your project, and set the bool documentTextIsAsiaFont as true. Sample code:

Code: Select all

var dx = doc.SaveAsImage(0,150,150,true);

If there is any question, please let me know.

Best wishes,
