I installed ImageMagick and see several .exe's in the install directory (dcraw, ffmpeg, hp2xx, and magick.
But most the examples I see are like this, using a "convert" command.
convert -define jpeg:size=200x200 hatching_orig.jpg -thumbnail '100x100>' \
-background skyblue -gravity center -extent 100x100 pad_extent.gif
I'm totally unclear if magick.exe replaces convert, or if convert is a subcommand of the magick.exe.
This is what I tried and the response:
"c:\Program Files\ImageMagick-7.0.7-Q16\magick.exe" -define jpeg:size=510x510 Sacred_Geometry_Flower_Of_Life_BlueGreen_Test1.jpg -thumbnail '100x100>'-background skyblue -gravity center -extent 100x100 pad_extent.gif
magick.exe: unable to load module 'C:\Program Files\ImageMagick-7.0.7-Q16\modules\coders\IM_MOD_RL_JPEG_.dll': The specified module could not be found.
# error/module.c/OpenModule/1275.
magick.exe: no decode delegate for this image format `JPEG' # error/constitute.c/ReadImage/509.
On the install, I didn't check the box circled below:
I'm still unclear if I could say magick.exe convert but all the examples just show running convert.
The second problem was security; I found another stackoverflow, but now I can't find the URL for it. They suggested giving user=everyone full control to the Windows install directory. Not a good thing to do, but I was more concerned with a quick solution at the moment.
#Mark in the comment above mentioned the quotes. I thought he meant around the directory name, but it turns out the the -thumbnail parms need to be in double quotes instead of singles quotes (at least on Windows).
You have added Imagemagick to the system path so you only need magick. You have not installed legacy file so you can not use convert. Do not use '' anywhere but "" Using "" will still work on Linux systems. \ is a Linux line continuator and I belive you should use ^
I install imagemagick and it works; no changing of permissions etc.
This should work:
magick -define jpeg:size=200x200 hatching_orig.jpg -thumbnail 100x100> -background skyblue -gravity center -extent 100x100 pad_extent.gif
Why not try something simple first to prove to yourself it works?
magick hatching_orig.jpg pad_extent.gif

I can't seem to find a way to properly convert my images to bmp using imagemagick. Whenever I use this website with the current settings it works flawlessly in my program. https://online-converting.com/image/convert2bmp/
I've tried these commands:
convert disney.jpeg -format bmp:format=bmp4 out.bmp
convert disney.jpeg -define bmp:format=bmp4 -type truecolor -compress none out.bmp
Nothing seems to work. Not sure how to set up imagemagick so that it gives me back the same format as the website.
As for the program, you basically feed it the bmp file. It works when I convert with the website, but not with imagemagick.
I'm talking about this metadata:
I know that this command:
magick mogrify -strip image.jpg
can clear all the info. But I don't know is it possible to write some metadata with ImageMagic?
It seems like magick identify -set can probably do what you have in mind - I just need a minute to test it myself, here's the corresponding part from the man page of identify:
-set attribute value set an image attribute
I'll edit my findings into this answer in a few mins :)
Edit:
This seems to work:
convert input.png -set new_attribute "attribute value" output.png
At least it works according to imagemagick's identify -verbose, I can't test if these properties show up on windows too.
It should also be simple to overwrite other metadata, simply by first finding the actual key with identify -verbose, I guess.
For more information, here's the official documentation:
https://www.imagemagick.org/script/command-line-options.php#set
I am trying to generate an image that is 1px wide and 100px tall of a gradient, which goes from white to #3532CB, and then save it in my directory as topgrad1.png
After changing the directory to the image folder in cmd.exe, I entered:
convert -size 1x100 gradient:white-#3532cb topgrad1.png
When entered, it gives the result of: Invalid Parameter - 1x100
How can I solve this?
That error indicates you're accessing a Windows command "convert.exe", probably in the "C:\Windows\System32\directory". You need to make sure your ImageMagick's "convert" command is in your PATH, or call your IM "convert" with the full path. Or if you're using IM7, you should be using "magick" instead of "convert" anyway, and still make sure it's in your PATH.
In Imagemagick, at least on Unix systems, you need to quote your colors, especially if using hex or rgb(...) colors. So
convert -size 1x100 gradient:"white-#3532cb" topgrad1.png
I am converting .psd to .png files inside folder with one. How to keep same name of every file in folder with different extension ?
For example I enter in folder images and then from terminal I execute
$ convert *.psd *.png
but it gives names to .png just numbers not the same as appropriate .psd image.
Use the -set and formatting options.
convert *.psd -set filename:base "%[basename]" "%[filename:base].png"
See "Long Form Attribute Percent Escapes" and "Filename Percent Escapes" docs.
Update
The mogrify utility that ships with imagemagick can also be used.
mogrify -format png *.psd
Note: Be careful with mogrify as the docs state...
This tool is similiar to convert except that the original image file is overwritten (unless you change the file suffix with the -format option) with any changes you request.
If you are on Linux, Unix or Mac OSX, you could use in a terminal window with Bash shell:
for i in *.psd; do
convert $i ${i/.psd/.png}
done
I deliberately do not advertise mogrify any more. It is too dangerous for every user who doesn't know it already, and who comes to this website to ask for help. mogrify is overwriting your original files in some cases (of course not when converting PSD->PNG)
Or, even simpler:
mogrify -format png *.psd
I like the top answer,
that being said, in later versions of ImageMagick, the command is
convert *.psd -set filename:basename "%[basename]" "%[filename:basename].png"
as also mentioned by #jan-glx and #jomel imperio
I'm generating text images using imagemagick by passing user inputs via command. I'm concerned that a user could enter something malicious.
# regex pattern
[^\s\w\.&!?"]
# image generation code, in Ruby
"convert -quality 100 -background black -fill red -font Times-Bold -size x50 label:'#{#line1}' output.jpg"
No it's a not :)
