### := Pixel area The
pixel
coordinates
(x,y)
refer
to
the
area
(x,y)..(x+1,y+1)
in
raster
space.
An
image
of
size
(w,h)
is
thus
mapped
to
a
raster
space
of
size
(w,h)
(raster
space
size
if
given
as
edge
length,
not
sample
count).

PixelIsPoint
|
= 1
|
Each
image
pixel
represents
an
infinitesimal
point
in
raster
space.

# := Pixel point The
pixel
coordinates
(x|y)
refers
to
the
point
at
(x|y)
in
raster
space.
An
image
of
size
(w,h)
is
thus
mapped
to
a
raster
space
of
size
(w-1,h-1)
(raster
space
size
if
given
as
edge
length,
not
sample
count).
