I'm not sure how to go about positioning an image. What I'm trying to do is place the image in the center of the page. This code works pretty good but it distorts the image instead of using its original size.
How can I modify this to use the existing image size instead of just this square?
public static void InsertResellerLogo(Document profileDocument, string logoPath)
{
string fullLogoPath = HttpContext.Current.Request.PhysicalApplicationPath + @"\CustomLayout\" + logoPath;
if (File.Exists(fullLogoPath))
{
// Set coordinates
int lowerLeftX = 400;
int lowerLeftY = 400;
int upperRightX = 200;
int upperRightY = 200;
// Get the page where image needs to be added
Page page = profileDocument.Pages[1];
using (FileStream imageStream = new FileStream(fullLogoPath, FileMode.Open))
{
// Add image to Images collection of Page Resources
page.Resources.Images.Add(imageStream);
// Using GSave operator: this operator saves current graphics state
page.Contents.Add(new Operator.GSave());
// Create Rectangle and Matrix objects
Aspose.Pdf.Rectangle rectangle = new Aspose.Pdf.Rectangle(lowerLeftX, lowerLeftY, upperRightX, upperRightY);
Aspose.Pdf.DOM.Matrix matrix = new Aspose.Pdf.DOM.Matrix(new double[] { rectangle.URX - rectangle.LLX, 0, 0, rectangle.URY - rectangle.LLY, rectangle.LLX, rectangle.LLY });
// Using ConcatenateMatrix (concatenate matrix) operator: defines how image must be placed
page.Contents.Add(new Operator.ConcatenateMatrix(matrix));
XImage ximage = page.Resources.Images[page.Resources.Images.Count];
// Using Do operator: this operator draws image
page.Contents.Add(new Operator.Do(ximage.Name));
// Using GRestore operator: this operator restores graphics state
page.Contents.Add(new Operator.GRestore());
}
}
}
