- In every grid-accepting inlet, a list may be sent instead; if
- it consists only of integers, it will be converted to a
- one-dimensional grid. Else it may contain a single "#" sign and
- integers on both sides of it, where the ones to the left of it are
- fed as arguments to an imaginary [#redim] object and the one to the
- right of it are fed through that [#redim].
- In every grid-accepting inlet, an integer or float may also be sent;
- it will be converted to a zero-dimensional grid (a scalar).
- a grid has an associated number type that defines what are the possible values for its elements
- (and how much space it takes). the default is int32.
- a single-dimensional grid of 3 elements (a triplet) is called dim(3). a
- three-dimensional grid of 240 rows of 320 columns of triplets is called
- There is a sequence in which elements of a Grid are stored and
- transmitted. Dimension 0 is called "first" and dimension N-1 is
- called "last". They are called so because if you select a
- position in the first dimension of a grid, the selected part is of the same
- shape minus the first dimension; so in dim(240,320,3) if you select
- row 51 (or whichever valid row number), you get a dim(320,3). if you select
- a subpart two more times you get to a single number.
- At each such level, elements are sent/stored in their numeric order,
- and are numbered using natural numbers starting at 0. This ordering usually
- does not matter, but sometimes it does. Most notably, [#import], [#export] and [#redim] care about it.
- On the other hand, order of dimensions usually does matter; this is
- what distinguishes rows from columns and channels, for example.
- Most objects care about the distinction.
- A grid with only 1 element in a given dimension is different from one
- lacking that dimension; it won't have the same meaning. You can use this
- property to your advantage sometimes.
- Zero-dimensional grids exist. They are called dim(). They can only contain
- a single number.
This section is useful if you want to know what a picture is in terms of a grid.
A picture is a three-dimensional Grid: 0:rows 1:columns 2:channels
