jit.gl.imageunit

Render Open GL

Description

The jit.gl.imageunit object loads any Apple Image Unit and permits the processing of incoming matrix and texture data, with resulting texture output, similar to jit.gl.slab.
For more information on Apple Image Units, please see Apple's Core Image developer pages.
The jit.gl.imageunit object requires one argument: the name of a drawing context. A named drawing context is a named instance of a jit.window, jit.pwindow, or jit.matrix object that has an instance of the jit.gl.render object associated with it. This value may also be set via the OB3D drawto attribute.

Messages

geteffectlist		Sends the names of all the available Image Units out the right-most outlet.
getparam	name [symbol]	Sends the data values for the indicated shader parameter for the currently loaded Image Unit out the right-most outlet. (synonym for getparamval)
getparamdefault	name [symbol]	Sends the default data values for the indicated shader parameter for the currently loaded Image Unit out the right-most outlet.
getparamidentity	name [symbol]	Sends the data values to result in no effect for the indicated shader parameter for the currently loaded Image Unit out the right-most outlet.
getparamlist		Sends the names of all the currently loaded Image Unit parameters out the right-most outlet.
getparammax	name [symbol]	Sends the recommended maximum value for the indicated parameter for the currently loaded Image Unit out the right-most outlet.
getparammin	name [symbol]	Sends the recommended minimum value for the indicated parameter for the currently loaded Image Unit out the right-most outlet.
getparamtype	name [symbol]	Sends the name of the datatype for the indicated parameter for the currently loaded Image Unit out the right-most outlet.
getparamslidermax	name [symbol]	Sends the recommended maximum UI value for the indicated parameter for the currently loaded Image Unit out the right-most outlet.
getparamslidermin	name [symbol]	Sends the recommended minimum UI value for the indicated parameter for the currently loaded Image Unit out the right-most outlet.
getparamval	name [symbol]	Sends the data values for the indicated shader parameter for the currently loaded Image Unit out the right-most outlet.
loadeffect	name [symbol]	Loads the given Image Unit.
param		Sets a parameter of the imageunit (e.g., param param_name [list of param values] ).
sendinput	message [list]	Sends the input jit.gl.texture object attached to the active inlet the corresponding message.
sendoutput	message [list]	Sends the output jit.gl.texture object the corresponding message.
read	name [symbol]	Loads the given Image Unit. (synonym for loadeffect)

Attributes

Name	Type	g/s	Description
thru	int		Thru mode flag (default = 1) When the flag is set, a matrix is output when another one is received.
activeinput	int		Input number used for jit_matrix method (default = 0) Useful for multiple input Image Units used from Java or JavaScript.
adapt	int		Enables or disables adapting and resizing to input source dimensions (default = 1).
colormode	symbol		The colorspace mode to use for each input textures (default = auto). Supported modes are: auto luminance intensity depth lumalpha rgb argb uyvy
dim	int		The dimensions of the output jit.gl.texture object when adapt is disabled (default = 256 256)
dimscale	float		Sets the scaling of output dims based on the object's leftmost input.
fx	symbol		Image Unit filter name (default = "Color Matrix") Possible choices are values returned from geteffectlist. Similar to loadeffect method, but can be specified as an attribute argument.
inputs	int		Input count (default = 2)
out_name	symbol	(get)	Returns the name of the internal jit.gl.texture object.
paramsafe	int		Parameter limit flag (default = 0) Permits the limiting of parameter values to the range specified by the Image Unit.
verbose	int		Verbose mode flag (default = 0) In verbose mode, the jit.gl.imageunit object will print out messages useful for debugging.
