Current image fields allows for entering a user specified image, but no ability to crop the image to fill the space proportionately.

When I create an an image field, I can currently specify that the user defined image fill to the bounds disproportionately (squashed to fit) or filling the space to the image's largest edge, but lacks the ability (like Indesign) to ‘fill space proportionately’ which results in the image being set to the outer limits of the frame and anything else being automatically masked.

I can see this working under the current system, specifically where the placement of the image can be moved about in the advanced settings. All that is lacking would be a scale handle or dialog box to enter a percentage scale.

This is similar to many online avatar creators where you can upload an image and then enlarge or move the image within the defined cropping.

As a designer, controlling the proportions and placements of images entered in user forms is pretty crucial. My only work around at the moment is to create boxes to the exact proportions of my end users camera, which is not always controllable.

I am trying to fill in a PDF and the editable field loses focus frequently, even while typing. I keep having to click back into the box to fill in my information. System details here:

In Acrobat Pro DC, when adding a new Digital ID, there is an attribute 'Email'. Please allow all email addresses in that field. Do not arbitrarily limit characters in email addresses to: a-z A-Z 0-9 . @ - _

Today I want to use an address, from+dsig@example.com, using a '+' character. This is perfectly legal in my email address, and I should be able to use it in a digital ID.

Beyond that, email addresses are no longer limited to a subset of ASCII Latin letters. Addresses in many scripts are now legal, e.g. Hindi ईमेल-परीक्षण@सार्वभौमिक-स्वीकृति-परीक्षण.संगठन or Arabic
تجربة-بريد-الكتروني@تجربة-القبول-الشامل.موريتانيا or Chinese 電子郵件測試@普遍適用測試.組識.澳門 or many others.

How to reproduce:
In Acrobat Pro DC (2021.001.20135) on macOS 10.13.6 High Sierra, do Acrobat Pro DC… Preferences…. Signatures… Identities and Trusted Certificates, More… The Digital ID and Trusted Certificates Settings dialogue appears.
Click on the "Add Digital ID" icon (picture of an ID card with a "+" on top). The "Add Digital ID" dialogue appears.
Select radio button "A new digital ID I want to create now", and press Next >. The Add Digital ID dialogue becomes a form with 7 fields.
In the "Email Address" field, type an address containing a "+", or a non-Latin character. Fill in the other fields reasonably. Press Next >.

Observed behaviour: The following alert dialogue appears:

Acrobat Security
The 'Email' attribute contains an illegal character.
Only the following characters are permitted: a-z A-Z 0-9 . @ - _

Expected behaviour: the Digital ID creation process continues, accepting the email address.

Discussion: Digital IDs are stored in files with the extension .p12.
They are presumably PKCS #12 format archives. RFC 8399 "Internationalization Updates to RFC 5280" specifies how to store such international email addresses, and my own little address with a "+" sign, in digital IDs.
I have a Digital ID in a .p12 file, which was created by a previous version of Adobe Acrobat Pro in December 2020, which has "+" sign in the email address. Thus Acrobat's limitation on email address characters seems to be a recent regression.

I am currently in graduate school. I use adobe acrobat pro DC all the time to convert my classes powerpoints into pdfs. Once they are formatted as a pdf, I can take notes on them, and it sticks.
I just realized I have been doing it wrong. I have been using the Add Text option, an option within the fill & sign tool. While this has been most effective in taking notes on powerpoints and helping me study, there have been many issues with it.
The fill & sign tool is not made for quick note taking and texts. Adobe Acrobat DC should create an Add Text Tool that is separate from the one found within the fill & sign. An add text tool that can allow you to jot notes down on a document with ease and efficiency. That would resolve my issues of my text just freezing, then "disappearing", and to only end up in another part of the document I am working on. And, I think many people could benefit from this tool.
