説明

I would like to be able to load an image from a file (though any source would be best) and know when it was available for manipulation in a synchronous way. To know when individual manipulations have completed. My application would like to load a number of images sequentially (validating input) and then once all are validating, start processing them though separate/different/combined sequences.

Calling Jimp.load(, <WITH SOMETHING INDICATING DON'T USE PROMISES>) to return an object that can be manipulated and cloned.

Tried finding a library that doesn't require some tortuous combinations of Promises that ultimately don't work for just simply loading an image file and knowing when it has been loaded and is manipulatable.

調査方針
Review the Jimp source code, particularly the image loading functions in /packages/core/src/index.js. Understand how the existing asynchronous (promise based) API works, especially the `Jimp.read` method. Determine the minimal changes required to add a synchronous alternative, possibly by wrapping the promise based code with synchronous wrappers using libraries like `deasync` or by restructuring to support both synchronous and asynchronous flows. Check the issue comments and any related PRs for additional context.
