Very nice !

What did I forget to answer? I seem to have applied all the review comments.

[jeromelaban]

The build was not passing at that time, we'll need to review the Sample from the APK now :)

[jeromelaban]

I've checked quickly the samples app on a device, and it works! Very nice! It should be interesting to make sure that the ScrollViewer that show the document is able to scroll horizontally, otherwise it's cropped. I'm not too sure about the API, but is there a way to show the pdf originally scaled to the available view size?

I have applied your suggestions. What are the doubts about implementing the API?

[workgroupengineering]

can someone restart the CI?

[jeromelaban]

Very nice! It's getting there!

Two observations:

• Resizing of the image does not work, though I don't know if it's a ScrollViewer issue on Uno's end, or if it's some missing configuration
• The "Arrange to Width" does not seem to be working properly, where the width of the PDF is larger than the available size on screen. Is this expected?

Thanks for the review,
I double check with UWP

[workgroupengineering]

I verified.

• It seems to be a scrollviewer problem.
• I added a test to verify that scaling works correctly.

@workgroupengineering thanks for taking the time to rebase on master! We'll take a look again and see if there's anything else to adjust.

[jeromelaban]

This is looking very good! Just one small adjustment and we can merge this!
