Question
I'd like to know how to convert png and gif files with alpha channel to jpg with white background with paperclip
I tried this but, it doesn't work
has_attached_file(
:photo,
:whiny => false,
:styles => {
:medium => ["300x300>", :jpg],
:thumb => ["100x100>", :jpg]
},
:convert_options => { :all => '-alpha white -background white'}
)
It saves the file with the gray background.
Solution
-alpha remove -background white
is preferable. white
is not a valid argument for -alpha
.
OTHER TIPS
here the solution
has_attached_file :photo,
:styles => {
:medium => ["300x300>",:jpg],
:thumb => ["100x100>", :jpg]
},
:convert_options => {
:all => '-background white -flatten +matte'
}
