ruby - Convert PPT into Images in Rails -

-

i using docsplit gem convert ppt images

docsplit.extract_images(uploaded.path.to_s, :size => '550x', :format => [:jpg],:output=>"#{rails.root}/public/images")

it convert take more time . can convert other way please me.

im using docsplit well, , if meant application idling/loading while docsplit converting ppt files should keep in mind that:

every process takes time, application "stuck" until job done.

therefore, should run heavy job/tasks takes long time - in background / in delayed job

if so: users won't stuck!

(dont forget should let them know job "in process", won't think there error)
