Re: scaling down an image gives red and blue shadows?

6.8.9.9 is over 100 versions old. You might consider upgrading IM also. However, it looks to be patched at July 2017. So it may be OK. Though you could check to see if there is a more current patch. My guess is it is your version of dcraw.

Re: scaling down an image gives red and blue shadows?

I ran your cr2 image with your command on my IM 6.9.9.23 Q16 Mac OSX and got no red speckle distortion and you show in your output. convert cr2:"_MG_9449.CR2" -resize 75% test1.jpg Also what version of dcraw and libjpeg? I am using dcraw @9.27.0_2 jpeg @9b_0 Perhaps you need to upgrade one or both.

Re: scaling down an image gives red and blue shadows?

I downloaded the example.nef from https://www.online-convert.com/file-format/nef and processing it on IM 6.9.9.23 Q16 Mac OSX with the following command: convert nef:example.nef -resize 75% example.jpg The result was a bit darker than the new file, but the colors were good. So I reprocessed as conve...

Re: scaling down an image gives red and blue shadows?

Which of the two commands are giving you trouble? Or are you running both commands on the same image taking the output from the first command and using it for the input of the second command.

Re: scaling down an image gives red and blue shadows?

Sorry, but I need to know the exact version of ImageMagick and the date associated with it. Use convert -version I also need to be able to download your input and output image. I do not know how to get those from imgur. I only see one image. Also it appears that I have to login and I have no access.

Re: PDF > PNG Conversion Issues

I ran my command 20 times and none of them had striping like on yours. Did you try my command without the -quality?

Re: The way to use convert –strip command line from system operational perspective.

Show us the data before you used strip. Perhaps the orientation was already correct. Or post and example JPG for which you are having trouble so we can test that. ** So, how can I get "meta data pertaining to EXIF", the first data that you showed me to know exif data in detail? I do not understand t...

Please always post your IM version and platform when asking questions. Also your exact command line and both the input and output images. There is no example where you have "example here" See the top-most post in this forum "IMPORTANT: Please Read This FIRST Before Posting" at http://www.imagemagick...

This command works fine for me on IM 7.0.7.11 Q16 Mac OSX magick -colorspace sRGB test_export.pdf -background white -alpha remove out.png Note that you should put -colorspace sRGB before the (vector) PDF input. Or use profiles after reading the PDF. Also note that -quality is different form png than...

Re: Convert command from ImageMagick does not work, and saying convert: unable to open image :

As I mentioned in your other post:

try

Code: Select all

find / -name in.jpg
and

Code: Select all

find / -name in.JPG
You may get lots of permission denied, but it should find the path to the file if it exists.

Lowlight now works properly to maintain the transparency in both IM 6.9.9.24 beta and IM 7.0.7.12 beta

Is this your original JPG or after you did -strip? I have an image that has the following meta data pertaining to EXIF: Orientation: TopLeft Properties: date:create: 2017-11-15T18:07:57-08:00 date:modify: 2009-12-05T16:59:52-08:00 exif:ColorSpace: 1 exif:ComponentsConfiguration: 1, 2, 3, 0 exif:Comp...

Re: The way to use convert –strip command line from system operational perspective.

One other point. ImageMagick will read your JPG, decompress it, strip the meta data, then compress it again before saving when using convert or mogrify. That may cause a change in the quality of the result, since JPG is a lossy compression. If you do not want this to happen, then use EXIFTOOL to rem...

Re: The way to use convert –strip command line from system operational perspective.

I just tested mogrify on one JPG image that had EXIF data and it remove the EXIF data according to identify -verbose P1050001.JPG

Code: Select all

mogrify -strip P1050001.JPG
works fine for me on IM 6.9.9.23 Q16 Mac OSX.

It also works fine using IM 7.0.7.11 Q16 Mac OSX.

Code: Select all

magick mogrify -strip P1050001.JPG

Re: The way to use convert –strip command line from system operational perspective.

What is your IM version and platform? Can you post a link to one of your JPG files that have EXIF data that you want to remove. I can test to see if it works on current versions of ImageMagick.

How did you check the images after running the command to see if the EXIF data was still there?
