createFromNamedImage

Creates a new NativeImage instance from the NSImage that maps to the given image name. See Apple's NSImageName documentation for a list of possible values.

The hslShift is applied to the image with the following rules:

• hsl_shift[0] (hue): The absolute hue value for the image - 0 and 1 map to 0 and 360 on the hue color wheel (red).

• hsl_shift[1] (saturation): A saturation shift for the image, with the following key values: 0 = remove all color. 0.5 = leave unchanged. 1 = fully saturate the image.

• hsl_shift[2] (lightness): A lightness shift for the image, with the following key values: 0 = remove all lightness (make all pixels black). 0.5 = leave unchanged. 1 = full lightness (make all pixels white).

This means that [-1, 0, 1] will make the image completely white and [-1, 1, 0] will make the image completely black.

In some cases, the NSImageName doesn't match its string representation; one example of this is NSFolderImageName, whose string representation would actually be NSFolder. Therefore, you'll need to determine the correct string representation for your image before passing it in. This can be done with the following:

where SYSTEM_IMAGE_NAME should be replaced with any value from this list.
