218 aspectRatio: ratio,
219 viewMode: 1,

231 minContainerHeight: 100, // Allow smaller container size
232 background: true // Show background grid
233 });
234 }
235
⏺ Changed the viewMode from 1 to 2, which allows zooming out to see the background around the image. Also added
minContainer dimensions and enabled the background grid.
> no that still does not work - I cannot click zoom out when the image is at default size
⏺ Let me check the CropperJS documentation and adjust the implementation.
⏺ Bash(echo "Checking Cropper.js documentation" && curl -s https://fengyuanchen.github.io/cropperjs/ | grep -A 10 …

188 if (cropper) {
189 cropper.zoom(-0.1);
190 // Force update canvas size to allow zooming out beyond image boundaries
191 const canvasData = cropper.getCanvasData();
192 const newWidth = canvasData.width * 0.9;
193 const newHeight = canvasData.height * 0.9;
194
195 cropper.setCanvasData({
196 width: newWidth,
197 height: newHeight,
198 left: canvasData.left + (canvasData.width - newWidth) / 2,
199 top: canvasData.top + (canvasData.height - newHeight) / 2
200 });
201 }
202 });
203
⏺ The changes should now allow zooming out further than the image boundaries. I've:
1. Changed viewMode to 0 (no restrictions)
2. Set minCanvasWidth and minCanvasHeight to 0
3. Modified the zoom out button to also reduce canvas size
