Background Image not working properly on spire pdf

[padalja2]

Hi,

We are finding some issues while trying to set a water mark image on spire pdf using .net core. Here is the code to attach the water mark. The images are embedded as a resource in a DLL file. I have attached a sample PDF as a reference. The highlighted code seems to have some issue with dynamic height and width. We are using latest spire version 5.10.0.

We have a working code as a .net DLL with old spire version and now we are trying to convert that code to .net core


Stream wpWatermarkStream = null;
System.Drawing.Image wpWatermark = null;

wpWatermarkStream = GetImageStream(watermarkImage);
wpWatermark = GetImage(watermarkImage);
int imgWidth = wpWatermark.Size.Width;
int imgHeight = wpWatermark.Size.Height;
if (wpWatermark != null)
{
foreach (PdfPageBase loPage in loPDF.Pages)
{
loPage.BackgroundImage = wpWatermarkStream;
loPage.BackgroundRegion = new RectangleF(foatWatermarkPositionX, foatWatermarkPositionY, imgWidth, imgHeight);
}
}

private System.Drawing.Image GetImage(string image)
{
Assembly assembly = Assembly.GetExecutingAssembly();
System.Drawing.Image retImage = null;

foreach (var resourceName in assembly.GetManifestResourceNames())
{
if (!string.IsNullOrEmpty(resourceName) && resourceName.Contains(image))
{
using (var stream = assembly.GetManifestResourceStream(resourceName))
{
retImage = System.Drawing.Image.FromStream(stream, true);
break;
}
}
}
return retImage;
}

private Stream GetImageStream(string image)
{
Assembly assembly = Assembly.GetExecutingAssembly();
Stream streamImg = null;

foreach (var resourceName in assembly.GetManifestResourceNames())
{
if (!string.IsNullOrEmpty(resourceName) && resourceName.Contains(image))
{
streamImg = assembly.GetManifestResourceStream(resourceName);
}
}
return streamImg;
}

Hello,

Thank you for your inquiry,
You mean you can't dynamically set the width and height of the background image? I tried setting different widths and heights for the background image but found that everything works fine. In order to help us further investigate, could you please provide us with your input files and a runnable project for reference? You could upload your project to the DropBox or OneDrive and then share the download link with us. Also, please tell us your OS information (e.g. Win7, 64bit) and region setting (e.g. China, Chinese). Thanks in advance.

Or if I misunderstood, please provide more detailed information to help us better understand your requirements, such as your desired output.

Sincerely,
Brian
