Hi, experts!

I use the next code (VBScript) to add image inside the pdf-file:

Dim ClassName

Dim LicenseKey

Dim FileName

ClassName = "DebenuPDFLibrary64AX1114.PDFLibrary"

LicenseKey = "****" ' INSERT LICENSE KEY HERE

FileName = "C:\Users\damir\Downloads\111\22.pdf"

Pic = "C:\Users\damir\Downloads\111\sign.png"

Dim DPL

Dim Result

Set DPL = CreateObject(ClassName)

Result = DPL.UnlockKey(LicenseKey)

If Result = 1 Then

DPL.LoadFromFile FileName , ""

d = DPL.AddImageFromFile(Pic, 0)

lWidth = DPL.ImageWidth

lHeight = DPL.ImageHeight

Call DPL.SelectPage(1)

h = DPL.PageHeight

w = DPL.PageWidth

Call DPL.DrawImage(w/2, h/2, lWidth, lHeight)

Call DPL.SaveToFile("C:\Users\damir\Downloads\111\SignedFile.pdf")

End If

Set DPL = Nothing

It's works great, but not for each pdf-file. I can understand the reason. The string "d = DPL.AddImageFromFile(Pic, 0)" doesn't return me "0" Non-zero, so it looks like imade adding works. Maybe the reason it's a lot of layouts. Maybe image is under the layout.

Please help me!

You may want to edit your post and remove your license key.

Edited. I solved the problem. I type the coordinates incorrect.

Damir,

The ImageWidth and ImageHeight functions return the width and height of the image in pixels.

To get the DPI of an image you need to use ImageHorizontalResolution and ImageVerticalResolution. With these values you can calculate the true width and height of the image if drawn at a 1:1 ratio.

This is important because all of the Drawing functions are specified using the current measurement system set which could be points, mm or inches. Using the pixel width / height returned by ImageWidth / ImageHeight will result in possibly strange results.

This is why you are forced to use w/2 and h/2 in order to get a smaller image.

Here is the correct code to add and draw an image at a 1:1 ratio.

Andrew, thank you for answering. I'll test "Image...Resolution" method in my code. I really have a trouble with "strange results", wich I get via "ImageWidth(Height)" method. Thank you for example too
