ROThumbnailGenerator
Create thumbnail images by a given URL (supports at the moment PDF, Images and Videos).
Installation
ROThumbnailGenerator is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "ROThumbnailGenerator"How to use
The ROThumbnail class is responsible for creating thumbnails by a given URL. The method getThumbnail(url:NSURL) does internally check the supported file types and uses the corresponding implementation of ROThumbnailGenerator.
At the moment there are the following file types supported:
- PDF (.pdf)
- IMAGE (.png, .jpg, .jpeg)
- VIDEO (.mov, .m4a)
You can retrieve the thumbnail of a given URL like that:
var thumbnailImage = ROThumbnail.sharedInstance.getThumbnail(fileUrl)If you want to add a new implementation of the ROThumbnailGenerator you can do this by implementing the ROThumbnailGenerator class and define your supported file extensions you are going to handle with this implementation.
Here is a small example:
class ImageThumbnailGenerator : ROThumbnailGenerator {
var supportedExtensions:Array<String> = ["png", "jpg", "jpeg"]
func getThumbnail(url:NSURL) -> UIImage {
return UIImage(data: NSData(contentsOfURL: url)!) ?? UIImage(named: "Piktogramm_IMAGE")!
}
}You can add your implementation with the following call:
ROThumbnail.sharedInstance.addThumbnailGenerator(yourThumbnailGenerator)License
