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...

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

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.

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

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?

Re: convert pdf to pdf produces huge pdf

I do not see any point to piping from ImageMagick to Ghostscript to do further processing. If you want to change the density use

gs -rXRESxYRES

in Ghostscript.

Or add all your gs arguments to the delegates.xml file in ImageMagick for PS or PDF (wherever the sDEVICE=gs

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

You cannot use a wild card for both input and output using convert. If you want to process a whole folder of files and keep the output names the same as the input names, then use mogrify rather than convert. See http://www.imagemagick.org/Usage/basics/#mogrify ImageMagick does not watch folders to r...

Lower the quality value is all I can suggest. Sorry, I am not an expert on PDF files.

Re: convert pdf to pdf produces huge pdf

ImageMagick is a raster processor, not a vector to vector processor. So if you have a vector PDF and you convert it to PDF using ImageMagick, it will rasterize the PDF to pixels (not vectors) and imbed the raster image in a vector PDF shell. That will make the output much larger than the input. So i...
