Technical details

  • Device name: Pixel 3a emulator
  • Android version: 12
  • App version: pre-release 2.25.x - 2.25.0-RC2 in addition to previously reported 2.24.2. Regression from CWA 2.23.2.

Describe the bug

The folding guide cross on an exported EU certificate is not vertically in the center of the paper, although horizontally it is centered. The cross is vertically displaced about 4.5 mm.

Distances in mm from edge to center cross

App Version left right top bottom comment
2.23.2 104.55 104.55 147.76 148.99 correctly centered
2.25.0-RC2 104.76 104.78 144.15 152.90 vertically displaced
Expected 105 105 148.5 148.5 dimensions for center of DIN A4

Steps to reproduce the issue

On Desktop

  1. Use Android Studio Device File Explorer to transfer German EU vaccination certificate PDF to the emulator

In CWA App

  1. Tap Scan
  2. Tap Open File
  3. Navigate to vaccination certificate in File app and tap on file, tap "Continue"
  4. Tap three-dot symbol
  5. Select Display Print Version, tap "Next"
  6. Tap Share symbol
  7. Tap Drive symbol

  5. Click Tools > Measure > Measuring Tool
  6. Use mouse to measure from edges to center cross

Expected behavior

The folding cross should be in the center of the document. DIN A4 has the standard dimensions 210 x 297 mm, so the cross should be at 105 and 148.5 mm from the respective paper edge.
