convert -adjoin results on a multitiff with inverted colors

[rpgomes]

Hi,

I used the command:

convert -adjoin 0001.tif 0002.tif 0003.tif M0001.tif

The images were joined, but in inverted way. White/black became black/white.

Witch option should I use to avoid this?

Thank you
Rui Gomes

Hi again,

I tried -negate option and it works fine.

Thanks

For tif you don't need adjoin, I don't think.

Have you tried

convert image1.tif image2.tif ... imageN.tif multiframe.tif

perhaps the inverted colors is due to +adjoin

Inverted colors will be nothing to do with adjoin, but the input Tiff file format. There is an option to fix the reading of the file for these types of tiffs.

Can you help me on that option?
Thanks
