Also, the logo is now stored as a BMP. Turnaround time on that thing is one click, we're nowhere near done reaping the benefits of indexed colour, etc.

The "braille" library, contrary to
|
|
its name, in fact a library for the
|
|
drawing of graphics using the...
|
|
"repurposed" Braille characters in
|
|
OC's font. This library is meant to
|
|
be usable easily from applications,
|
|
including those that mix text and
|
|
graphics in a normal UI.
|
|
|
|
Upon requiring, you get a wrapMeta'd
|
|
table, which consists of two
|
|
functions at this time:
|
|
|
|
calcLine(x, y, w, span, get
|
|
[, colour]) -> calc:
|
|
Given an X/Y character position,
|
|
and a given width in characters,
|
|
along with the get function:
|
|
get(xp, yp) -> r, g, b
|
|
(NOTE: These coords are 0-based!)
|
|
and colour (a number, the amount of
|
|
difference required to cause an
|
|
FG/BG change - not giving this
|
|
disables colour output),
|
|
output spans to the span function:
|
|
span(x, y, str, bg, fg)
|
|
|
|
new(x, y, w, h, cbs, colour) -> nux:
|
|
Creates a NeoUX component for an
|
|
embedded braille image.
|
|
X, Y, W and H are in characters,
|
|
each character offering 2x4 pixels.
|
|
cbs is a table that may have the
|
|
following fields:
|
|
|
|
selectable : The selectable flag.
|
|
key/clipboard :
|
|
Identical to NeoUX's.
|
|
touch/drag/drop/scroll: See NeoUX
|
|
for full details, but the xI and
|
|
yI parameters are gone, and the
|
|
X/Y coordinates are in Braille
|
|
pixels. The button/direction value
|
|
if any remains unchanged, but in
|
|
an earlier position.
|
|
|
|
and must have a "get" function:
|
|
get(window, x, y) -> r, g, b
|
|
Gets the R/G/B of a pixel on the
|
|
image, with a 1-based pixel X/Y.
|
|
Details of conversion are hidden
|
|
from the user of this library for
|
|
future improvement by the end-user
|
|
or another party, but in no-colour
|
|
mode, 255, 255, 255 will always
|
|
show white and 0, 0, 0 will always
|
|
show black.
|
|
colour enables colour (see above),
|
|
though if displayed on a screen
|
|
without colour, this option is
|
|
ignored for that time.
