jit.freeframe Reference

Utilize FreeFrame effects

jit.freeframe

Description

Provides support for using FreeFrame effects within Jitter. It supports both single and dual input effects, and 32-bit and 16-bit data sizes.

Examples

Discussion

The object's interface is complicated by the FreeFrame architecture -- each effect may have a completely different set of parameters.

More about Matrix Operators

The Jitter MOP

Since the matrix is Jitter's focus, it is not surprising that the majority of Jitter objects fall in this category of Matrix Operators. Every Matrix operator has some number of matrix inputs and some number of matrix outputs. Matrix inputs are referred to by the names "in", "in2", "in3", etc., from left to right, and matrix outputs are referred to by the names "out", "out2", "out3", etc., from left to right--i.e. the names are appended by the input/output number except for the first (leftmost) input and first (leftmost) output which are simply named "in" and "out". We will refer to the input or output name names as the "I/O-name".

Matrix inputs and outputs typically each have their own matrices internally where information is kept. This is necessary because Jitter is an asynchronous framework (i.e. all the matrices don't arrive at all inputs at the same time). Various aspects of matrix inputs and outputs can be set using the command [I/O-name] combined with one of the following suffixes: "_dim" which will set the dimensions of the specified I/O matrix, "_type" which will set the type of the specified matrix, "_planecount" which will set the plane of the specified matrix, or "_name" which will set the name of the specified matrix. There is one special case which does not have an internal matrix and this is the first input "in". This is the case since this special input actually triggers the calculation of the matrix operator, so it doesn't need to be cached until a calulation takes place, unlike the other inputs. Therefore there is no mechanism to set the dim, planecount, type, or name of "in".

Matrix operators accept what we'll refer to as "matrix args"--i.e. [planecount (int)] [ type (symbol)] [dim (int list)]. if these arguments are present, the adapt attribute will be turned off, otherwise it will be turned on. If adapt mode is turned on, each time a matrix is received in the first input, there will also be the equivalent of setting the dim, planecount, and type attributes to that of the input matrix. If the other inputs and outputs are linked to these attributes, this will affect their linked attributes as well. See the "MOP" table to determine which inputs and outputs will be linked to which attributes when adapt mode is turned on. For the leftmost input this is not applicable, and hence all columns are labelled "n/a".

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.

MOP Arguments

planecount [int]

Optional

Explicitly sets the number of planes for the output and any righthand inputs. If this is absent, the Matrix Operator will typically adapt to the lefthand incoming matrix attributes, except for special case operators.

type [symbol]

Optional

Explicitly sets the type of the matrix for the output and any righthand inputs. If this is absent, the Matrix Operator will typically adapt to the lefthand incoming matrix attributes, except for special case operators.

dimensions [list]

Optional

Explicitly sets the dimensions of the matrix for the output and any righthand inputs. If this is absent, the Matrix Operator will typically adapt to the lefthand incoming matrix attributes, except for special case operators.

MOP Attributes

adapt [int]

Matrix adaptation flag (default = 0 if matrix arguments are present, otherwise 1) When the flag is set, the jit.matrix object will adapt to the incoming matrix planecount, type, and dimensions.

[in/out]_dim [32 ints]

The matrix data dimensions (default = 1 1)

[in/out]_name [symbol]

The input or output name of the matrix (default = UID)

[in/out]_planecount [int]

The number of planes in matrix input our output data. Except in special cases, this value is equal to the planecount.

[in/out]_type [symbol]

The input or output matrix data type. Except in special cases, this value is equal to type.

outputmode [int]

Output mode (default = 1 (calculate and output matrix))
0 = No output
1 = Calculate and output the matrix
2 = Pass input (no calculation)
3 = Pass output (no calculation)

Supported data types are char, long, float32, or float64.

MOP Messages

bang

Equivalent to the outputmatrix message.

clear

Sets all cell values in a matrix to zero.

exportattrs

Arguments

filename [symbol]
Exports an object's current attributes values in XML format. If no filename is specified, a file dialog will open to let you choose a file.

getattributes

Sends a sequence of lists out the object's right outlet describing the object's attributes, one line per attribute. Each line listing line takes the form attribute attribute-name get get-value set foo set-value data-type(s) number-of-values .

getstate

Sends a sequence of lists describing the object's state out the object's right outlet, one line per attribute. Each line listing line takes the form attribute-name attribute-value1 attribute-value2 ... attribute-valueN .

importattrs

Arguments

filename [symbol]
Imports attributes specified in XML format to set the object's attributes. If no filename is specified, a file dialog will open to let you choose a file.

jit_matrix

Arguments

matrix-name [symbol]
Handles input for the named matrix. If this messages is received in the left inlet, output is typically triggered. If this message is received in any other inlet, the data is typically cached until the jit_matrix message is received in the left inlet.

outputmatrix

Sends the matrix out the left outlet.

summary

Sends a sequence of lists describing the object and it attributes and messages out the rightmost outlet of the object. The first output line takes the form summary objectname object-name . The second and third lines describe the number of inlets and outlets for the object in the form summary (matrixinputcount/matrixoutletcount) number-of-(inlets/outlets) . The fourth line describes the matrixoutput in the form summary matrixoutput descriptor planelink planelink-value typelink typelink-value dimlink dimlink-value types data-type(s) . Each attribute for the object is then listed, one attribute per line. Each line listing takes the form summary attribute attribute-name attribute-value1 attribute-value2 ... attribute-valueN .

Attributes

fx [symbol]

The currently loaded effect

inmode [symbol]

The matrix input mode (jitter/freeframe).
The inmode and outmode attributes provide an optimization when building chains of jit.freeframe objects. Because Jitter and FreeFrame use different byte-padding, matrices generally have to be copied to a new buffer when the arrive at a jit.freeframe object, and copied back into a Jitter matrix after processing, before output. If several jit.freeframe objects will be used to sequentially process data, this copying step can be avoided.
The first object in the chain should have inmode set to jitter, and outmode set to freeframe. All subsequent objects should have both attributes set to freeframe, except for the last one, which should have inmode set to freeframe, and outmode set to jitter.

numparams [int]

g/s(get)

The number of parameters for the currently loaded effect (default = -1)
A value of -1 indicates that there is no loaded effect.

outmode [symbol]

The matrix output mode (jitter/freeframe).
The inmode and outmode attributes provide an optimization when building chains of jit.freeframe objects. Because Jitter and FreeFrame use different byte-padding, matrices generally have to be copied to a new buffer when the arrive at a jit.freeframe object, and copied back into a Jitter matrix after processing, before output. If several jit.freeframe objects will be used to sequentially process data, this copying step can be avoided.
The first object in the chain should have inmode set to jitter, and outmode set to freeframe. All subsequent objects should have both attributes set to freeframe, except for the last one, which should have inmode set to freeframe, and outmode set to jitter.

Messages

anything

If the message selector matches the name of a parameter, functions like the param message, taking a single float (or symbol, in the case of text parameters) argument.

If the message selector matches the word get, followed by the name of a parameter (e.g. getbrightness, the message has the same effect as the getparam message, but requiring no further arguments.

geteffectlist

Sends a list out the object's right outlet comprising the names of all available FreeFrame effects, preceded by the word effectlist. On Macintosh, FreeFrame effects must be located either in the /Library/Application Support/FreeFrame/> folder, or in a directory called FreeFrame Plugins , within the Max search path. On Windows, FreeFrame effects must be located either in the C:\Program Files\Common Files\FreeFrame\ folder, or in a directory called FreeFrame Plugins , within the Max search path.

getparam

Arguments

param [symbol/int]
Sends a list out the object's right outlet containing the current value of the parameter specified by the param argument (either by name or by index into the list returned by getparamlist). The list is formatted as param param param-val param-display . The param argument is the name of the parameters, the param-val the value, and param-display is an alternate display value, for parameters whose "real value", as understood by the parameter, lies outside of the range 0-1.

getparamlist

Sends lists out the object's right outlet describing the parameters for the currently selected effect, one list per parameter (see numparams). The list or lists are in the form paramlist param-name param-type .

All parameters, regardless of type (with the exception of text), accept a single floating-point number between 0 and 1 as input.

The parameter types are: boolean, event, red, green, blue, xpos, ypos, text, standard.

After all parameters have been listed, the message paramlist done is output.

loadeffect

Arguments

effect-name [symbol]
Selects an available FreeFrame effect for use. The effect must be specified by its name, as reported by the geteffectlist message.

param

Arguments

param [symbol/int]
value [float/symbol]
Sets the value of the parameter specified by the param argument (either by name or by index into the list returned by getparamlist). All parameters, regardless of type (with the exception of text), accept a single floating-point number between 0 and 1 as input. See the getparamlist message for additional information on parameter types.

reload

Causes the object to rescan the FreeFrame plugins folders and add any new plugins to its list of effects. See the geteffectlist method for more details.
