Basic question

[Hosting.mgr]

Sorry to be the newbie but I have a ton of images (tiff) files that I would like to reduce and I am having a hard time figuring out the command line.

I would like the images reduced to 1024X768 and would appreciate some guidance. I have tried the -resample and -density. Once I get the command line down I can figure out how to convert all the files in a directory. Windows command line

Code: Select all

convert input.tif -resize 1024X768 output.jpg

This will resize the image so that the longest dimension is either width 1024 or height 768 and will maintain the aspect ratio.
If you want to remove all EXIF data etc. apart from the colour profile use -thumbnail instead of -resize

I am receiving an error "Incorrect value for "Photoshop"; tag ignored. 'TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/850." but it worked. I think the error was throwing me off.

Was that an error or warning. IM will issue warnings if it does not know about some meta tag, but that does not mean anything bad. Tiff based files have many meta tags that can be used to save information, but they do not affect the image pixel data.

Yes they are a warning message. Is there anyway of suppressing those warning?

-quiet. See http://www.imagemagick.org/script/comma ... .php#quiet
