ImageSpec is a lightweight module designed to extract width/height dimensions from most standard image formats, as well as SWFs.
This is a work in progress. I intend on expanding this to include other details (EXIF, various metadata, etc.) as well.
# From a file in your file system instance = ImageSpec.new('/path/to/your/file')
# From a URL instance = ImageSpec.new('')
# From an IO stream file = File.new('/path/to/your/file', 'rb') instance = ImageSpec.new(file)
instance.width instance.height instance.content_type
Pretty simple, huh?
