This saves both disk space and bandwidth by compromising a little on quality.
Only thumbnails are affected; full-size images are still saved in full detail.
Previously, a NotAllowedException would be thrown if an invalid session
was encountered. However, these exceptions were not caught, and hence
would yield a fatal uncaught exception error.
At this point in Kabuki, the ErrorHandler class has not been registered yet
for error handling purposes. This error is therefore not visible if the PHP
ini directive 'display_errors' is set to 'Off'. As this is the default
production value, the script would fail with a blank page in such cases.
This removes the limit of downloading albums only; tags are fine, too.
Now using UserFacingException for certain exceptions, as these are
displayed to the user.
Removing the inheritance of HTMLController, as we intend to output binary
data only.
To create inline thumbnails locally, the previous version of the photo uploader
used base64 representations of the local files to be uploaded. While this is
effective, it is a little wasteful. When uploading several photos at once, this
could even lead to the page becoming less responsive.
This commit changes the process such that the photos are actually resized on a
canvas, only using the local original as a buffer. Hence, only the resized
photo is retained in memory.
This code is used to efficiently determine the most saturated colour in an image,
Kabuki uses this as the highlight colour on a page, but this styling has always
been disabled in HashRU Pics. Hence, we can safely remove the code, freeing up
some CPU cycles in the process. ;-)
