Separate to tiff

[snibgo]

I'm very impressed with the current Windows IM (which the web page says is 6.8.5-2, but convert says is 6.8.5-0). It seems to handle greyscale images in the way I want. Equalize, normalise, auto-level, level and contrast-stretch don't need "-set colorspace RGB" to work as I would expect. Even better, I get consistent results for file types PNG, TIFF, JPG and JP2.

One bug so far:

Code: Select all

convert hald:8 h.tiff
convert h.tiff -separate h.tiff

This should create 3 files: h-0.tiff, h-1.tiff and h-2.tiff. Instead, it creates just h.tiff, which corresponds to the red channel.

The problem does not occur for PNG, JPG or JP2.

Sorry, false alarm. This is not a bug. IM correctly creates a multi-page tiff, which can then be combined to recreate the original.
