convert -size ignore ratio

[immortal26]

I'm trying to figure out how to ignore the ratio of just the height.

So like... convert -size 1000x500\! ... so that it's always 500 in height but doesn't have to be 1000 in width, just 1000 is the greatest it can get in width.

This is being used to create a label of text IE: convert -size 1000x500\! -font Candice label:Hello ... something of that nature.

use the ^ symbol

convert image -resize "1000x500^" result

see http://www.imagemagick.org/script/comma ... p#geometry

It does not apply to creating an image using -size! But does work with changing sizes such as with -resize, -thumbnail, etc

-size is used for image creation. Labels, captions canvases (xc:), gradients, etc.. New images have no existing 'ratio' to be preserved, so such flags are currently not used.

You do not need to specify a size, but over the last few years you can now combine -size and -pointsize entries for generating labels and captions of specific size (or just hieght) specifications. Basically you have a lot of control options.

See IM examples Labels and Captions for details.

-resize and -thumbnail etc are used for resizing images can also leave out one of the deminsions or specify to turn off image ratio preservation. See Image Resizing in IM Examples for details.
