The IM-Version is 6.8.9-7 Q16 (2014-09-15). Where do I find the libtiff version? I use Win7 on a 64bit System with 24GByte of RAM. I just found out that with my exiftool command not all tags had been copied. Especially one XMP-tag, holding all the setup for B, was not copied. I have to find out, how...

Yes, I had already done these checks. Sorry, I should hvae mentioned that: Both pages have the desired endiness. Also with EXIFtool GUI I had seen that the bits per pixel are set correct for both pages. I will try to make further experiments. Perhaps I come across something which sheds light on the ...

Unfortunately settung the endianess to MSB did not help. Yes, the IR image is white with just some black dust specks. This is indicated by the mean gray value of 49000 for the original from B and 52000 for my artifical image. But the level should be detected by B automatically. If I extract the IR-c...

Okay, I did that and compared the output. First difference encountered is the Endianess: MSB for the file liked by B, and Endianess: LSB for my fake multipage.tif. The channel statistics is also different, which I expect, since the data are different. In both cases I see the RGB-image on page 1 with...

Wow, that is a fast reply! Thank's a lot! The images are too large to attach (190MByte, and 60MByte). Creating small versions may take a while. However, each individual input (RGB and IR) looks perfectly okay when opened with various software (imageJ, photoshop, IrfanView ...). So I assume that some...

Good morning, I have the following plan concerning scans of my slides with two different software: Scans from software A are better than scans from software B. However, the tools for image processing provided by software B are better than the tools from software A. So my aim is to use software A for...

Thanks a lot for your reply. Unfortunately the trick with the alpha channel did not work. So I will set up a macro for imageJ and split the pixels there. If I have then a series of images in a folder, with the RGB channels named image_001_R.tif, image_001_G.tif, image_001_B.tif, image_002_R.tif etc....

Great, that worked perfectly! As I mentioned, I used imageJ to get the grayscale Images, to begin with. In the end I would, of course, like to do this in one go over many files in imagemagick. So the first question would be, if it is possible to convert the 4x16bit/pixel TIF image into a 3x16bit/pix...

Hi, thanks for your reply. Perhaps I should give some more details. I have an image being the raw data from a slide scanner. The raw image consists of pixels, each of which is a 16bit number for the R, G, B and IR channel. I have used imageJ to extract from this raw image 4 separate images as 16bit ...

Hello,

being new to imagemagick I have a most likely simple question:

I have three 16bit-TIF Images, corresponding to the R, G and B channel of a color image. How do I combine these into a single one-page 48bit-TIF color image?

Many thanks in advance for any hints.
