PDF viewer in Android which allows sharing the current page as an image so that I can share it with "Anki" > "Image Occlusion"

AnkiDroid (Android) Help

The institution where I’m studying in provides students with slides that contain learning material. I often read the slides on my Android device. These slides have many graphics which I use in my Image Occlusion cards.

This is my workflow for creating Image Occlusion cards from those slides:

  1. I open the PDF viewer installed on my Android device
  2. While reading the slides, I notice there’s some important information that I should remember, so I take an screenshot
  3. I open the gallery installed on my Android device
  4. I crop the screenshot so that the image only contains the content of that particular slide. In other words, I crop the Android status bar which is at the top, the Android navigation bar which is at the bottom.
  5. Press the “Share” button which the gallery app shows when viewing an image and select “AnkiMobile” > “Image Occlusion”

It would be great if some PDF viewer in Android allowed the user to share the current page as an screenshot with another application. Thus, I wouldn’t need to do the manual work of cropping the Android status bar and navigation bar. Some days, I have had to manually crop more than 20 screenshots of slides. I felt that I could make better use of my time and let the computer do that repetitive task.

I wonder if there are some free and open-source PDF viewer in Android that allowed the user to share the current page as an image. If anyone is aware of such application, please let me know.

I mainly use Librera Reader to read PDF files on my Android device, but it doesn’t have this feature, so I have opened a feature request in the repository of Librera Reader: https://github.com/foobnix/LibreraReader/issues/1390

I don’t know about your phone, but when I take a screenshot on my phone, I get a “mini preview” of the screenshot in the upper right corner of my screen.

Tapping it allows me to edit the screenshot. Then I copy paste it from the clipboard into Anki. I use this a lot and it’s almost perfect.
