jit.fx.brcosa
Adjust image brightness/contrast/saturation
Description
Permits you to simultaneously adjust an image's brightness, contrast and saturation. This is useful for achieving a variety of color effects.
Attributes
bypass[int]
Bypass effect processing flag (default = 0). When enabled the input is passed through to the output without processing.
adapt[int]: 1
Adapt output dims to input (default = 1). When enabled the output dimensions will match the leftmost input dimensions.
brightness[float]
Brightness (default = 1.) Values below 1. (to 0.) reduce brightness, while values above 1. increase it. 1. represents no change.
contrast[float]
Contrast (default = 1.) Values below 1. (to 0.) decrease contrast, bringing the image closer to grey (which represents the average luminance of the image frame). Values above 1.0 increase contrast. 1.0 represents no change. Negative values affect a color inversion, but with similar results.
dim[2 ints]
The output texture dimensions. When adapt is enabled this will be set automatically to the leftmost input.
luma[3 floats]
Luma (default = 0.62 0.62 0.62). The tint of the image in RGB format when the contrast is different than 1.
saturation[float]
Saturation (default = 1.) Values below 1. (to 0.) decrease saturation, bringing the image closer to greyscale. Values above 1. increase saturation. 1. represents no change. Negative values affect a color inversion, but with similar results.
OB3D Attributes
drawto[symbol]
The named drawing context in which to draw (default = none) 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.
enable[int]
Enable flag (default = 1) When the flag is set, drawing is enabled.

Possible values:
'8'
'9'
'10'
'11'
'12'
'13'
'14'

'30'
'36'
'48'
'64'
'72'
hint[symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick[int]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
JS Painter File
patching_rect[4 floats]: 0. 0. 100. 0.
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation[int]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 0. 0. 0. 0.
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect[4 floats]
write-only
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size[2 floats]
write-only
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor[4 floats]
Sets the color for the object's text in RGBA format.
textjustification[int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
varname[symbol]
Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.
