描述

Here I faced a curious problem: I made an alpha animation for a png image in AE, but after exporting,the OPACITY attribute of that animation didn't appear in the json file.However.If I made this just for layer(not image Layer), OPACITY appeared as expected. Any ideas?

研究方向
Investigate the exporter code in the Keyframes repository, specifically how layers and images are handled. Look for where opacity is applied to layers and understand why it's missing for images. Check the JSON output structure to identify the difference. Consider modifying the exporter to include opacity for image layers by mirroring the layer opacity logic. Review any existing tests for layer opacity and add similar tests for images.
