Carrierwave - Resizing images to fixed width
Just put this in your uploader file:
class ImageUploader < CarrierWave::Uploader::Base version :resized do # returns an image with a maximum width of 100px # while maintaining the aspect ratio # 10000 is used to tell CW that the height is free # and so that it will hit the 100 px width first process :resize_to_fit => [100, 10000] endend
Documentation and example here: http://www.imagemagick.org/RMagick/doc/image3.html#resize_to_fit
Keep in mind, resize_to_fit
will scale up images if they are smaller than 100px. If you don't want it to do that, then replace that with resize_to_limit
.
I use
process :resize_to_fit => [100, 10000]
Use 10000
or any very big number to let Carrierwave know the height is free, just resize to the width.
@iWasRobbed: I don't think that's the correct solution. According to the link you pasted about resize_to_fit
: The maximum height of the resized image. If omitted it defaults to the value of new_width.
So in your case process :resize_to_fit => [100, nil]
is equivalent to process :resize_to_fit => [100, 100]
which doesn't guarantee that you will always get the fixed width of 100px
Wouldn't a better solution actually be:
process :resize_to_fit => [100, -1]
This way you don't have to limit height at all
EDIT: Just realized this only works with MiniMagick, For RMagick you seem to have no option but to add a large number to the height
