PDF() of pen input control generates non transparent background

Hello Community,

I have tried to do a simple test where I have a container with an image and a pen input control on top of the image.

Then, I use a button to call the new PDF function and generate the PDF of the container, and it does generate the PDF ... but the pen input control that initially is transparent in the container, when converted to PDF has a black background.

Do you know if this is a know limitation of the PDF function ?

Or a way to make it work ?

Here is a sample screenshot of my application:

the button executes the following command: UpdateContext( { tmppdfcontent: PDF( Container2, {ExpandContainers: true} ) } );
and the pdf viewer control just points to the tmppdfcontentvariable created in the button

Thanks, Victor.

Hello @OroskiBR01 ,

thanks for testing and answering.

I also opened a support ticket to Microsoft and was answered that:
the PDF Function in PowerApps is an Experimental feature and is not meant for production use and may have restricted functionality
but at the same time, I was informed that it was added as something to be fixed related to the PDF() function
Regards, Victor.

Has anyone figured out any work arounds to resolve this? I'm experimenting with replacing the pdf input with an image control after the signature has been put in but still working on it.

Hey @vllanso and @Sigfreid, I found a solution that works for me.

So we have the PenInput1 and Image1, go ahead and add another Image2 with the same x, y, width, and height as the PenInput1. Then set the Image2 property to PenInput1.Image.

Now in the OnSelect of your button that generates the pdf, before everything else add...
Set(varPenVisible, 1);
Then at the very end of your OnSelect add this code...
Set(varPenVisible, 0)

That way we can set the visibility of the PenInput1 to...
If(varPenVisible = 1, false, true)
And the visibility of the image we added (Image2) to...
If(varPenVisible = 1, true, false)

Now when you hit the button to generate pdf, PenInput1 will disappear, but the image you drew (Image2) will be in the exact same spot. The two images overlay each other nicely on the pdf. Here's what I got before and after.

Thank you @OwenS28 ... ! that is brilliant !

I just tested and it does work, and the resulting PDF has the overlay of both things.

Thanks again.
