Image Conversion Takes Long Time

[nuwan]

Hi iceblue support,

I am trying to convert attached file to images using following code.

doc.LoadFromFile(<PDF File>);

for (int p = 0; p < doc.Pages.Count; p++)
{
using (System.Drawing.Image img = doc.SaveAsImage(p))
{
img.Save(<Save Path Per Each Page>);
}
}


For this particular file doc.SaveAsImage(p) take vary long time (few minutes) to complete when other PDF files processed in milliseconds. Please let me know what causing this issue and is there any workaround.

Kind Regards,
Nuwan

Dear nuwan,

Thanks for your inquiry.
I have tested the sample file with Spire.PDF Pack(Hot Fix) Version:3.9.27, and the process of the method doc.SaveAsImage(p) is very fast. Please try to use this version.
If there is any question, please let me know.

Sincerely,

Hi Betsy,

Thanks for the reply. I have tried the hot-fix but still having the same issue. The full code I am using is:

using (PdfDocument doc = new PdfDocument())
{
doc.LoadFromFile(@"C:\Tests\PDF\Image Conversion Test File.pdf");
for (int p = 0; p < doc.Pages.Count; p++)
{
using (System.Drawing.Image img = doc.SaveAsImage(p))
{
img.Save(string.Format(@"{0}\{1}_{2}.png", @"C:\Tests\PDF", "Image Conversion Test File", p));
}
}
}

Please let me know if I am missing anything. I have tested large number of files and this is the only one that I am having issues with.

Kind Regards,
Nuwan
