How run a process only on the main version?

[mix]

Hi, I migrated to 0.5.x and I've a problem, previously I did this:

process :resize_to_fit => [800, 600]
process :optimize_image
process :watermark => Rails.root.join("public", "images",
"watermark.png")

version :thumb do
process :resize_to_fit => [80, 80]
process :optimize_image
end

And it worked, only the main version had the watermark, now with the
0.5 version it's added to the thumb too!

I tried to do version nil, version :nil, version "", but it doesn't
work... with :nil it create a new version and it keep the original
one, but it just want 2 version: the main one and the thumb

Any hint?

Thanks

anyone about this? ;)

I have a similar problem outlined this post:
http://groups.google.com/group/carrierwave/browse_thread/thread/c83d4ab2b35f08ae?hl=en

I needed a version which keeps the original size from the upload.

I've forked carrierwave and this is a commit that implements what I
needed. https://github.com/mulder/carrierwave/commit/d098295c0f326a124506ab06b8fc944acdf9dddf

I hate the name I gave it but here is how its used:

class IPhoneImageUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick

storage :file

process :resize => ['50%']

version :retina do
use_pre_processed_file!
end

# Pipes size_string param into an mini_magick resize call.
def resize(size_string)
manipulate! do |img|
img.resize size_string
img = yield(img) if block_given?
img
end
end
end


The use_pre_processed_file! is the method you want. After my commit
using this will make the version use the originally uploaded image to
apply its processing to, instead of building off main version.

I think this is a pretty useful feature. If some one can come up with
a better name i'll move things into a feature branch and wrap things
up with some specs then init a pull request.

Also if someone has a better implementation behind the scenes please
chime in.

That sounds like a useful feature, maybe something like:

version :thumb, :use_original_image => true do

end

That was my first through, but after looking at the code the version
method didn't seem to be working with an options hash. I didn't want
to open up that flood gate, so I just stuck with the ! method
approach. I'll all for the options hash method and we wouldn't need
the empty block either.

Jonas if you think the options hash is best I'll get that going.
Though we could probably support both if we wanted....

I have submitted a pull request that supports this option and even has
some specs for it.

I'm hoping to makes it in as we are using it and its working well for
us.
