How to convert JPG/PNG image to multi resolution ico using magick-wasm?
I found the following that uses ImageMagick cli: convert input.png -define icon:auto-resize="256,128,64,32,16" result.ico

Moreover how to pass the options similar to imagemagick cli while using magick-wasm
Example: magick -size 320x85 canvas:none -font Bookman-DemiItalic -pointsize 72 \ -draw "text 25,60 \'Magick\'" -channel RGBA -blur 0x6 -fill darkred -stroke magenta \ -draw "text 20,55 \'Magick\'" fuzzy-magick.png

Thanks in advance :)

You will need to translate the command line code to typescript/javascript. It might be possible that a feature that you want is not yet available and should be added.

What have you tried yourself so far and where are you stuck?

Tried the following. The code creates an icon from image. Not sure how to create a multi resolution icon.

ImageMagick.read(imageData, (image) => {
	image.resize(100, 100);
	image.write((data) => {
		console.log(data);
	}, MagickFormat.Ico);
});

magick identify .\icon.ico
.\icon.ico ICO 99x100 99x100+0+0 8-bit sRGB 41262B 0.000u 0:00.001

With the current release it is not possible to set the icon:auto-resize define but you will be able to do this in the next release:

ImageMagick.read(imageData, (image) => {
    image.resize(100, 100);
    image.settings.setDefine('icon:auto-resize', '64,32,16'); // removed 256 and 128 because of resize to 100x100.
    image.write((data) => {
        console.log(data);
    }, MagickFormat.Ico);
});
