background image issue with new version of Spire.office

[lsong]

I am working on PDF file generating with new version of Spire.Office(2.16.23). However, the watermark image is not showing properly. I noticed the following statement is obsoleted in the new version:
UseHighQualityImage
so I changed my code accordingly, but the watermark image still seems to stretch through the whole page. I down graded Spire Office to 2.15 and it works fine.
Could you please take a look this issue?

Thanks,
Lucy

Dear Lucy,

Thanks for your inquiry.
After an initial test with following code, I noted the property BackgroundRegion doesn't work using Spire.Office(2.16.23), so the watermark image always stretches through the whole page. Did you use same code ? If not, please provide us with your code and related files. Besides, I have logged the issue on BackgroundRegion in our bug tracking system.

Code: Select all

PdfDocument pdf = new PdfDocument();
PdfPageBase page  = pdf.Pages.Add();
Image img = Image.FromFile(@"F:\image\image1.jpg");
page.BackgroundImage = img;
page.BackgroundRegion = new RectangleF(300, 200, 80, 81);
pdf.SaveToFile("12807.pdf");

If you encounter same issue, there is a temporary solution for you , please first set the BackgroundRegion and then add image.

Code: Select all

page.BackgroundRegion = new RectangleF(300, 200, 80, 81);
page.BackgroundImage = img;

This is the code snippet of our application:

foreach (PdfPageBase loPage in loPDF.Pages)
{
loPage.BackgroundImage = loImage;
loPage.BackgroundRegion = new RectangleF(foatWatermarkPositionX, foatWatermarkPositionY, loImage.Size.Width, loImage.Size.Height);
}
The watermark image always stretches through the whole page with Spire.Office(2.16.23). It is working fine with Spire.Office(2.15)
