Scale Images GitHub Action

This action will scale all images in the image-folder to new images of the same type.

The sizes are hard coded to [250, 500, 1000]

Works on: Linux

Inputs

image-folder

Required The name of the folder that contains the images.

Outputs

scaled

The result of running the scaler: no images were found (0), all images found were already scaled (1), some/all images found were scaled (2)

Example usage

Invoking the scaling action

    - name: Run scaling step
      id: scale
      uses: turtlesec-no/scale-images@v1.0
      with:
       image-folder: 'test_images'

Checking the action output

    - name: No images found - scaling output 0
      if: steps.scale.outputs.scaled == '0'
      run: echo "No images found"

    - name: All images were already scaled - scaling output 1
      if: steps.scale.outputs.scaled == '1'
      run: echo "All images were already scaled"

    - name: Some/all images scaled - scaling output 2
      if: steps.scale.outputs.scaled == '2'
      run: echo "Some/all images scaled"

The images can then be commited in a subsequent step (example)

    - name: Commit image files
      working-directory: test_images
      run: | 
        git config user.email "bot@turtlesec.no"
        git config user.name "Turtle Bot (GitHub Action)"
        if [[ "$( git status --porcelain)" != "" ]]; then
          git add -A
          git commit -m "Updated image files"
          git push
        fi
