Could someone help me remove the strips from my TIFF image. I've been unsuccessful for two days now with syntax.

"C:\Program Files (x86)\ImageMagick-6.8.7-Q16\convert.exe" +set tiff:rows-per-strip: -verbose 011848CH.tif 011848CHm.tiff

I'm able to change the strips from 3 to 1 but I need to remove strips completely
"C:\Program Files (x86)\ImageMagick-6.8.7-Q16\convert.exe" -define tiff:rows-per-strip=1 -verbose 011848CH.tif 011848CHm.tiff

Thank you for any help you can provide guys!

As I understand it, strips are the TIFF data structure that contains pixels. A TIFF with no strips would contain no pixels.

My apologies if I'm incorrect with naming. You have striped tiff format from TIFF 4.0 and 5.0. I need to remove striped format due to poorly built application ingesting the TIFFs that are striped format. I would have thought the tiff:tile command would have removed the stripes but again unsuccessful. Striped tiffs can be converted to non striped, strip stripped, etc... whatever they call it. I've found so many spellings of the same meaning.

I can remove striped format using Tiffcp command line tool. But I really like ImageMagick but I'm just a beginner and need some expertise on how I can convert a striped tiff to a non-striped tiff.

Can you provide samples of "striped tiff" and "non-striped tiff" files? Put them somewhere like dropbox.com and paste the links here.

I wish I could. I'm working as a consultant and the images are owned by my client. I've been uncompressing / removing stripped from TIFF files for some time now. Just would like the capability with ImageMagick.

Only ImageMagick syntax I could find was to convert the image to tile and that would remove stripe.

If you have a process for "removing stripes", you could create an ordinary TIFF ("with stripes"), put it through that process, and put the two files here. Then someone might find how IM can replicate that process.

I don't have the older product that creates 4.0 and 5.0 TIFFs that would create .sStripped I just have the syntax to turn into tile TIFF 6.0 format. If I just open an old 4.0 or 5.0 stripped TIFF image in Photoshop it will automatically save the image as TIFF 6.0 replacing strip with tile format.

I believe you can create tiled tiffs in IM using a -define to specify the tile geometry. If you want a tiled pyramid, preface the output with PTIF:output.tiff But I have not tested any of this.

see the following:
http://www.imagemagick.org/script/formats.php#supported
http://www.imagemagick.org/script/comma ... php#define

Great find I have tested this string and syntax with my TIFFs in IM and the images still fail. After I run the identify command I see no change in strip count or any additionally added tile tags. I was hoping to offer a better solution to client with IM but I may need to resort back to LibTIFF using Tiffcp.

Could it be possible defect? I'm too new to product to say I feel comfortable saying its a defect.
I can modify the strip amount.
REM "C:\Program Files (x86)\ImageMagick-6.8.7-Q16\convert.exe" 011848CH.tif -define tiff:rows-per-strip=1 -verbose 011848CHm.tif

When I run the below I still have tiff:strip format in the file. I ran with identify
"C:\Program Files (x86)\ImageMagick-6.8.7-Q16\convert.exe" 011848CHm.tif -define tiff:tile-geometry=600x732 -verbose 011848CHm1.tif

IM is just not reporting the tile size. A suggestion to the developers is to add the tile size to the tiff info reported by -verbose in identify and convert.

Nevertheless it works. For example in IM 6.8.7.9 Q16 Mac OSX using the IM internal logo: image. See http://www.imagemagick.org/script/forma ... tin-images

convert logo: -define tiff:rows-per-strip=1 -define tiff:tile-geometry=128x128 logo_tile.tif

identify -verbose logo_tile.tif
