Standard types

ExifOrientation

On this page

How a stored image is turned to be seen upright (EXIF 2.32's orientation), named for where its first row and column are seen and written as EXIF's value: top_left is 1, right_top is 6.

Media and visual; not ordered; since Jadpo 0.1.0.

Make one

Pick one of its variants, ExifOrientation.top_left.

text.parse(raw, as: ExifOrientation) reads one from its text; text that isn't one at all fails malformed, such as 0, 9 or 06.

Variants

Variant Written
top_left 1
top_right 2
bottom_right 3
bottom_left 4
left_top 5
right_top 6
right_bottom 7
left_bottom 8

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

Text JSON
1 "1"
6 "6"
8 "8"

It is stored in one column named for the field, of type text. 6 is stored as '6'.

Shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value Shown
1 1
6 6
8 8

Operations

It has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
