jit.scope Reference

Visual matrix analysis tools

jit.scope

Description

jit.scope lets you visually inspecting matrix values and display them as waveform, vectorscope, histogram or parade visual data.

Examples

Arguments

None.

Attributes

accum [int] (default: 25)

Sets the amount of data, per pixel, to accumulate for display.

accum_desat [float] (default: 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).

bgcolor [4 floats]7.0.0

Sets the background color of the object in RGBA format

colormode [symbol] (default: argb)

Sets the color mode. The options are:

argb (the default)
uyvy

Possible values:

'argb'
'uyvy'

dstrect [4 ints]

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 [4 floats]

Sets the Graph Color in RGBA format. The graphcolor attribute is mapped to the elementcolor style color.

graphmode [symbol] (default: 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.

Possible values:

'luminance'
'rgb'

hgraphcolor [4 floats]

Sets the Graph Color displayed on hover in RGBA format. The hgraphcolor attribute is mapped to the selectioncolor style color.

interp [int] (default: 0)

Interpolation flag (default = 0) When the flag is set, the incoming matrix is interpolated when scaling to display.

mode [symbol] (default: 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

Possible values:

'waveform'
'vectorscope'
'histogram'
'parade'

planemap [4 ints]

Sets input plane to output plane mapping (default = 0 1 2 3 ...)

size [2 ints]

Sets the window size (width and height) (default = 320 240)

srcrect [4 ints]

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.

style [symbol] (default: )7.0.0

Sets the style to be applied to the object. Styles can be set using the Format palette.

Common Box Attributes

Messages

bang

Outputs the current matrix.

jit_matrix

Arguments

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.
