Use Apple Image Units Loads any Apple Image Unit and permits the processing of incoming matrix and texture data, with resulting texture output, similar to jit.gl.slab. Cycling '74 Jitter Jitter OpenGL messages to this 3d object TEXT_HERE TEXT_HERE matrix output if enabled TEXT_HERE dumpout TEXT_HERE Report available Image Units Sends the names of all the available Image Units out the right-most outlet. Report parameter values Sends the data values for the indicated shader parameter for the currently loaded Image Unit out the right-most outlet. (synonym for getparamval) Report default values Sends the default data values for the indicated shader parameter for the currently loaded Image Unit out the right-most outlet. Report the identity values 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. Report all available parameters Sends the names of all the currently loaded Image Unit parameters out the right-most outlet. Report maximum parameter values Sends the recommended maximum value for the indicated parameter for the currently loaded Image Unit out the right-most outlet. Report minimum parameter values Sends the recommended minimum value for the indicated parameter for the currently loaded Image Unit out the right-most outlet. Report data type for a selected parameter Sends the name of the datatype for the indicated parameter for the currently loaded Image Unit out the right-most outlet. Report maximum UI parameter values Sends the recommended maximum UI value for the indicated parameter for the currently loaded Image Unit out the right-most outlet. Report minimum UI parameter values Sends the recommended minimum UI value for the indicated parameter for the currently loaded Image Unit out the right-most outlet. Report a selected parameter value Sends the data values for the indicated shader parameter for the currently loaded Image Unit out the right-most outlet. Load an Image Unit Loads the given Image Unit. Sets a parameter value Sets a parameter of the imageunit (e.g., param param_name [list of param values]). Process a texture as input Sends the input jit.gl.texture object attached to the active inlet the corresponding message. Output a texture Sends the output jit.gl.texture object the corresponding message. Load an Image Unit Loads the given Image Unit. (synonym for loadeffect) Active matrix input Input number used for jit_matrix method (default = 0) Useful for multiple input Image Units used from Java or JavaScript. Source dimension adaptation Enables or disables adapting and resizing to input source dimensions (default = 1). Colorspace mode The colorspace mode to use for each input textures (default = auto). Supported modes are:
auto
luminance
intensity
depth
lumalpha
rgb
argb
uyvy
Output dimension The dimensions of the output jit.gl.texture object when adapt is disabled (default = 256 256) Output scaling Sets the scaling of output dims based on the object's leftmost input. Image Unit name 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. Input count Input count (default = 2) Texture name Returns the name of the internal jit.gl.texture object. Parameter limit flag Parameter limit flag (default = 0) Permits the limiting of parameter values to the range specified by the Image Unit. Thru mode flag Thru mode flag (default = 1) When the flag is set, a matrix is output when another one is received. Verbose mode flag Verbose mode flag (default = 0) In verbose mode, the jit.gl.imageunit object will print out messages useful for debugging. 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. Additionally it can reference the name of a jit.gl.node sub-context. This value may also be set via the OB3D drawto attribute. If no argument is present, the object is implicitly added to the first valid drawing context or sub-context found in the current patch or by searching up the patcher hierarchy.
