jit.matrix

The Jitter Matrix!

Description

The jit.matrix object is a named matrix which may be used to matrix data storage and retrieval, resampling, and matrix type and planecount conversion operations.

Messages

bang Outputs the currently stored matrix.
int Equivalent to the setall [int] message, followed by the bang message.
float Equivalent to the setall [float] message, followed by the bang message.
list Equivalent to the setall [list] message, followed by the bang message.
clear Sets all matrix values to zero.
exportimage filename [symbol]
file-type [symbol]
use-dialog [int]
Export the current frame as an image file with the name specified by the first argument. The optional second argument sets the file type (default = png). Available file types are png, bmp, jpeg, macpaint, photoshop, pict, qtimage, sgi, tga and tiff. An optional use-dialog argument of 1 will open a file dialog to allow you to enter the image file settings.
exportmovie filename [symbol]
FPS [float]
codec [symbol]
quality [symbol]
timescale [int]
Exports a matrix as a QuickTime movie. The exportmovie message takes an optional argument to specify a file name. If no filename is specified, a file dialog will open to let you choose a file.

The default FPS is 30. frames per second

The default codec is raw . Supported codecs are raw , cinepak , graphics , animation , video , componentvideo , jpeg , mjpega , mjpegb , sgi , planarrgb , macpaint , gif , photocd , qdgx , avrjpeg , opendmljpeg , bmp , winraw , vector , qd , h261 , h263 , dvntsc , dvpal , dvprontsc , dvpropal , flc , targa , png , tiff , componentvideosigned , componentvideounsigned , cmyk , microsoft , sorenson , indeo4 , argb64 , rgb48 , alphagrey32 , grey16 , mpegyuv420 , yuv420 , and sorensonyuv9 .

The default quality is max . Supported quality settings are lossless , max , min , low , normal , and high . Note that minimum quality is, in many cases, the codec's default quality. Use "low" quality for consistent results.

The default timescale is 600 units per second.

exprfill plane [int]
expression [symbol]
Evaluates expression to fill the matrix. If a plane argument is provided, the expression is applied to a single plane. Otherwise, it is applied to allphanes in the matrix. See jit.expr for more information on expressions. Unlike the jit.expr object, there is no support for providing multiple expressions to fill multiple planes at once with different expressions. Call this method multiple times once for each plane you wish to fill.
getcell position [list]
Sends the value(s) in the cell specified by position out the right outlet of the object as a list in the form cell cell-position0 ... cell-positionN val plane0-value ... planeN-value .
fillplane plane [int]
value [int]
The word fillplane, followed by an integer that specifies a plane number and a value, will fill the specified plane with the single value.
importmovie filename [symbol]
time-offset [int]
Imports a QuickTime movie into the matrix. If no filename is specified, a file dialog will open to let you choose a file. The time-offset argument may be used to set a time offset for the QuickTime movie being imported (the default is 0).
jit_gl_texture texture-name [symbol]
Copies the texture specified by texture-name to the matrix.
op The word op, followed by the name of a jit.op object operator and a set of values, is equivalent to including a jit.op object with the specified operator set as an attribute and this jit.matrix object specified as the output matrix. The additional value arguments may either be a matrix name or a constant. If only one value argument is provided, this matrix is considered both the output and the left operand. For example, "op + foo bar" is equivalent to the operation thismatrix = foo + bar, and "op * 0.5" is equivalent to the operation thismatrix = thismatrix * 0.5.
read filename [symbol]
Reads Jitter binary data files (.jxf) into a matrix set. If no filename is specified, a file dialog will open to let you choose a file.
setall value [list]
Sets all cells to the value specified by value(s). Position is specified of a list whose length is equal to the number of dimensions (dimcount).
setcell position [list]
val [literal]
value [list]
Sets the cell specified by position to the value specified by value. Position is specified of a list whose length is equal to the number of dimensions (dimcount). The optional arguments plane plane-number can be used to specify a plane. If a plane is specified, value should be a single number, otherwise it should be a list of numbers of size planecount - 1.
setcell1d The word setcell1d, followed by a number specifying an x coordinate and a list of values, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (1) is fixed.
setcell2d The word setcell2d, followed by a pair of numbers specifying x and y coordinates and a list of values, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (2) is fixed.
setcell3d The word setcell3d, followed by three numbers specifying x , y , and z coordinates and a list of values, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (3) is fixed.
setplane1d The word setplane1d, followed by a number specifying an x coordinate, a number specifying a plane, and a value, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (1) is fixed, or use the "plane" token to specify which plane to set.
setplane2d The word setplane2d, followed by a pair of numbers specifying x and y coordinates, a number specifying a plane, and a value, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (2) is fixed, or use the "plane" token to specify which plane to set.
setplane3d The word setplane3d, followed by three numbers specifying x , y , and z coordinates, a number specifying a plane, and a value, is similar to the setcell message but without the need to use a "val" token to separate the coordinates from the value since the dimension count (1) is fixed, or use the "plane" token to specify which plane to set.
val value [list]
Equivalent to the setall message, followed by the bang message.
write filename [symbol]
Writes matrix set as a Jitter binary data file (.jxf). If no filename is specified, a file dialog will open to let you choose a file.
