Bounds and Image Size Mismatch

[DavidBS]

Dear Sowmiya,

I'm having problems to put an image within signature bounds. I've to set the signature.bounds.height too high to avoid to crop any image.

See the code below and the image attached:

Dim ImageSize As SizeF = New SizeF(image.PhysicalDimension)

I set the Width.Bound large enough to contain a text.

Dim TotalSize As SizeF = New SizeF(ImageSize.Width + 200.0F, ImageSize.Height)

Dim Sig_Pos As New PointF(0, 0)

signature.Bounds = New RectangleF(Sig_Pos, TotalSize)

I want to draw the image using the entire vertical area of the Bounds.

signature.Appearance.Normal.Graphics.DrawImage(image, New PointF(0F, 0F), ImageSize)

As you can see, the image is croped. To avoid this, I have to add almost 30 points to the Signature.Bounds.Height ...

Am I doing something wrong?

Thanks a lot for your help.

Hi David, 

Thank you for contacting Syncfusion support.  

We have tried to reproduce the mentioned issue “Signature and image bounds mismatch” in our end with the provided code snippet. But we regret to let you know that it works fine in our end. Please find the below sample in which we have insert the image (based on image width and height) with signature appearance,

Dear Sowmyia,

You code functions like a charm.

I saw the PDF-Base related in you code is 17.2460.51 Pre-release and my package is 17.2460.46 (Winforms).

May the problem be related with this?

In time: I set the libraries that came with you code in my code and the results are still wrong. Interesting to notice that my code is exactly like yours (or vice-versa), but I saw a difference between images: my one is 96 DPI and yours is 72 DPI.

I will try to change my one to 72 DPI and see results.

See you soon.

Hi Sowmyia,

I ran your code with my image and PDF and everything was fine.

I ran also your code (WPF) using the libraries 17.2.0.46 and everything was fine.

But if I run my code even with your libraries (17.2.0.51) the results are still wrong.

However, I checked my code against yours and everything is similar.

So, I conclude the problem is related to some library used by PDF control v 17.2.0.46 .

I really cannot see any difference or problem related to the code itself.

Do Syncfusion has any patch/pre-release libraries (2.0.51) for Winform?

Thank you my friend.

Dear Sowmiya,

I FOUND the problem!

It's related to EnableValidationAppearance. 

If it is set to TRUE, the image is crop...

If it is set to FALSE, the image is normally printed.

So, I conclude this settings is using the field's bottom line... 

My question: since I'm using TimeStampServer and EnableLtv too, may I really need to set EnableValidationAppearance?

What is the real objective of this setting?

Again, I appreciate your time and efforts to help me here.

Kindest regards,

David

Hi David, 

It's related to EnableValidationAppearance.   If it is set to TRUE, the image is crop...  If it is set to FALSE, the image is normally printed.	We were able to reproduce the mentioned issue “Image is cropped while set true to EnableValidationAppearance”. We will update further details by 19th September, 2019.
since I'm using TimeStampServer and EnableLtv too, may I really need to set EnableValidationAppearance?  What is the real objective of this setting?	The main objective of this property is to add the dynamic signature validation appearance to the signature and it is not necessary to enable this property when using TimeStampServer and EnableLTV.
