I’m giving a brief talk at tonight’s Rails meeting in Chandler at 7:00pm on what we’re doing with attachment_fu and Kropper for upcoming face-based search service mugr.com. I’ll post the slides afterwards for those who can’t make it, but you won’t get to see the Über-secret developer build unless you come 🙂
Tag: attachment_fu
I recently integrated Kropper into a custom RoR application for OpenRain affiliate img surf. A fundamental flaw in the upload-save-crop-save process used by Kropper is that attachment_fu automatically scales down the image on first save to :resize_to dimensions. After the subsequent crop–which may result in a significant drop in resolution–the image is scaled back up to :resize_to dimensions: an ugly lossy operation.
The attachment_fu_skip_resize plugin gives attachment_fu the ability to temporarily bypass resizing of the full-size original image, thus allowing your final cropped photos to be of the highest quality as possible.
- Install the plugin.
- In your attachment_fu image class, add..
attr_accessor :skip_resize
- Any time you want to save an image without invoking resizing on the original image..
image.skip_resize = true image.save
Thumbnails will be generated at their defined resolutions regardless of the skip_resize flag.
