I have made you a Canvas Image Viewer which should do what you want.

Canvas can no longer be really big

issue: noted for future Work status: needs discussion affects: ucr priority: medium regression

**Describe the bug** [Power users group](https://community.appinventor.mi…t.edu/t/bug-large-canvas-crashes-companion-and-apk/25491?u=ewpatton): It used to be that the canvas could have really large width/height, but this is no longer the case. Making a large canvas crashes the app. This is due to the fact that in older versions of App Inventor we used software rendering but newer versions of App Inventor use hardware rendering. Hardware rendering places constraints on the size of resources drawn on the canvas object, and the background image violates those constraints in large Canvas components. **Affects** - [ ] Designer - [ ] Blocks editor - [x] Companion - [x] Compiled apps - [ ] Buildserver - [ ] Debugging - [ ] Other... (please describe) **Expected behavior** Large Canvas objects should not crash the companion (although at some point we will have OOM issues due to background image size). Existing apps that no longer work should resume working. **Steps to reproduce** 1. Create a Canvas in a project. Set its width/height to something large like 2048x2048 2. Connect companion or install APK on your device

Process:

Load an Image from the list (works with images on sdcard as well as google drive files)
Some javascript in the html page gets the aspect ratio of the image
Sets the image to an imagesprite on the canvas
You can move the image around (drag on image)
Resize the image using the slider

note: I couldn't get the canvas any bigger than 1792 x 1792 without the app crashing. Tested on Android 10/11

Here hopefully a version that will work on most phones, canvas sized to 1280x1280, just means you cannot enlarge as much as you may like.
