描述

Is your feature request related to a problem? Please describe.

When I receive product shots from the design team they often contain lots of whitespace in the form of transparent pixels around the item. I need a way to remove that transparency and change the image dimensions to fit the actual content of the image.

Describe the solution you'd like

Trim transparent pixels around the content of the image. Similar to the Image > Trim... > Transparent Pixels feature in Photoshop.

Does other service/app have this feature?

Yes, see https://www.photopea.com/

研究方向
Examine existing image processing operations in the `src/features` or `src/codecs` directory (e.g., resize, rotate) to understand the pattern. Locate the UI components for image editing, likely in `src/components/`. Implement a trim function that scans pixel data from edges inward to find the bounding box of non transparent pixels, then crops the image accordingly. Add a UI control, such as a button in the editor panel, to trigger the trim. Follow the existing code structure for consistency. Check the issue comments for any additional guidance from maintainers.
