Sorry to be thick

[ianboag]

I haven't figured out how I get this command line thing going ...

I have a BMP
I want to rotate it 180 degrees
then crop it by some specified amount
then add a watermark
then resize it down a bit
then make it a jpg

I bet there's someone who could show me the (DOS) batch file code that would do this

Call me thick ....

Cheers IB

Everybody has to learn at some point ianboag.
I am not a big batch file user but I have written some examples on my website.

Thanks Bonzo. I am a fairly competent batch file user - I just couldn't figure what program I invoke to get the functions. I sort of assumed it would be "ImageMagick" followed by specific commands. Now I understand (I think) ...

[snibgo]

It would be ...

Code: Select all

convert inputfile some_options outputfile

For some_options, see http://www.imagemagick.org/script/comma ... ptions.php

See also the usage page for loads of examples (but in Unix format): http://www.imagemagick.org/Usage/basics/

See my pages for loads of Windows BAT examples, but they are sometimes more advanced.

One thing to note is Windows has a convert program as well. I have never had a problem as I let Imagemagick install an environmental variable to Windows. I assume the people who have a problem do not do this and then instead of using Imagemagick convert to modify their image they are using the Windows program that renames files. So the outcome is an error message that confuses them.

You can rename the Imagemagick convert program to get around this. In IM version 7 you will be able to use magick instead of convert.
