You will now always need to set the define. The first extra channel could very well not be an alpha channel. You should change your code to this: `image.defineSet("tiff", "assume-alpha"...

I just noticed now that you don't call `defineSet` before you read the image? You should set this before you call the `read` method.

Without your image there is not much more we can do. It will be up to you now to attach a debugger and figure out what is happening.

Your response to our question was "Thanks" so it looked like you got it working and we could close this issue. Apparently that was not the correct conclusion.

I was able to force an RGB image by adding `-type truecolor` to the command line. Does that resolve your issue and can we close it?

That would mean someone would need to add that feature for you. I will mark this as an enhancement then and hope that someone will want to help you with...

I suspect that you are running out of memory because wasm only runs in 32-bit and has a memory limit. But I will need some time to investigate this.

Thanks for reporting this. I just pushed a patch to resolve this issue and this will be resolved in the next release.

Thanks for reporting this Fred. I updated the documentation and this should be available in a couple days.

Thanks for sharing the images but I have no idea what your issue is?
