jit.scope

Visual matrix analysis tools

Description

The jit.scope object is the video Swiss Army Knife cousin of the MSP scope~ object - it presents a number of modes for visually inspecting the values of a matrix and displaying them as waveform, vectorscope, histogram or parade visual data.

Arguments

None.

Messages

bang Outputs the current matrix.
jit_matrix window-size [list]
 Displays the input matrix by scaling to the window size.
(mouse) Clicking with the mouse will display a horizontal or vertical line trace and numerical cursor.

Attributes

Name Type g/s Description
accum int
def.:25 		Sets the amount of data, per pixel, to accumulate for display.
accum_desat float
def.:0.35 		When the jit.scope object is set to parade mode, this attribute sets the desaturation for the display (expressed as a float in the range 0. 1.0).
border float
def.:0. 		Window border flag (default = 1) When the flag is set, the window is displayed with a border.
colormode symbol
def.:argb 		Sets the color mode. The options are:

argb (the default)
uyvy
dstrect int Specifies the portion of the output matrix written to by the input frame (default = 0 0 (matrix width) (matrix height)) The proportions of the rectangle are expressed in the form left top right bottom . All values are relative to the top left corner of the object's viewing area.
graphcolor float
def.:0.8 0.3 0. 1. 		Sets the Graph Color in RGBA format.
graphmode symbol
def.:luminance 		When the jit.scope object is set to histogram mode, this attribute sets the data to be displayed. The options are:

luminance: displays a luminance (monochrome) display of histogram values
rgb: displays an overlaid set of histograms for R, G, and B values.
hgraphcolor float
def.:0.8 0.8 0. 1. 		Sets the Graph Color displayed on hover in RGBA format.
hpopupbackgcolor float
def.:0.2 0.2 0.2 1. 		Sets the Popup Highlight Background Color in RGBA format.
hpopupcolor float
def.:1. 1. 1. 1. 		Sets the Popup Highlight Text Color in RGBA format.
interp int
def.:0 		Interpolation flag (default = 0) When the flag is set, the incoming matrix is interpolated when scaling to display.
mode symbol
def.:waveform 		Sets the display mode of the jit.scope object. The modes are:

waveform: signal values (y) plotted over time (x)
vectorscope: an x-y plot of two signals
histogram: a plot of the disbribution of values for an input signal
parade: a scrolling display of R, G, and B values shown on a single screen
planemap int Sets input plane to output plane mapping (default = 0 1 2 3 ...)
popupbackgcolor float
def.:0. 0. 0. 1. 		Sets the Popup Background Color in RGBA format.
popupcolor float
def.:0.9 0.9 0.9 1. 		Sets the Popup Text Color in RGBA format.
size int Sets the window size (width and height) (default = 320 240)
srcrect int Specifies Specifies the portion of the input matrix used when copying an input matrix to the internal matrix. (default = 0 0 (matrix width) (matrix height)) The proportions of the rectangle are expressed in the form left top right bottom . All values are relative to the top left corner of the viewing area of the input matrix.
