Public Class methods

find(*args)

We override find to exclude the whole file contents (data, medium and thumb columns) from our result set.

The binary values should not be directly modified - Use self#from_blob instead.

from_blob(data, conf)

Creates or updates the logo for the conference (specified as the second parameter) with the data received as a raw image as the first parameter. Creates the medium resolution and thumbnail versions as well - RMagick calculations will only be done when storing images, not when serving them.

RMagick will throw out a Magick::ImageMagickError if an invalid image is received

Public Instance methods

medium_height()

Medium resolution height: Stored in the ‘logo_medium_height’ SysConf entry (defaults to 500 if not set)

If the full image is smaller than the medium image, there is no point in having an amplified (and blurry) medium image - So give back the original size.

medium_width()

Medium resolution width (proportional to medium_height, preserving the original image‘s aspect ratio)

thumb_height()

Thumbnail height: Stored in the ‘logo_thumb_height’ SysConf entry (defaults to 65 if not set)

thumb_width()

Thumbnail width (proportional to thumb_height, preserving the original image‘s aspect ratio)
