jit.gl.pix.codebox
Generates pixel processing shaders from GenExpr code
Description
The jit.gl.pix.codebox object generates new pixel processing shaders from GenExpr code. jit.gl.pix.codebox is essentially a jit.gl.slab object whose shader files are generated from GenExpr code.
Attributes
bgcolor[4 floats]
Sets the color for the object's background frame.
linenumbers[int]: 1
Show lefthand column containing line numbers for non empty lines.
linenumberwidth[int32]: 20
Set the width of lefthand line number column in pixels.

textcolor[4 floats]
The default textcolor (typically overridden by syntax coloring)
title[symbol]
Gen patcher title
t[symbol]
Gen patcher title
dirty[int]
read-only
Gen patcher dirty flag
type[symbol]
The output texture data type (default = auto). When type is auto the type is set by the input texture or matrix type.
Possible values:
'auto'
(
Adapt to input data type
)
'char'
(
8bit unsigned byte
)
'long'
(
32bit integer
)
'half'

16bit float
)
'float'
(
32bit float
)
'float16'
(
16bit float

'float32'
(
32bit float
)
thru[int]
Enable thru mode (default = 1). When the flag is set, texture output is sent whenever input is received.
texrect[4 floats]
Texture rectangle mapping values (default = 0 0 1 1...). The four values represent texture mapping coordinates for the left, bottom, right and top sides of the geometry rectangle, and can be used to easily crop the input image. There are four values for each texture input.
rectangle[long]
Enable texture rectangle mode on internal texture objects(default = 1). When enabled the internal GL texture is treated as a rectangular texture, and must be referenced using sampler2DRect and sampled using texture2DRect when sampled from a GLSL shader. When disabled the texture dimensions are upsampled to the nearest power of two value, and must be referenced and sampled using sampler2D and texture2D. Certain texture attributes and GLSL effects require rectangle mode disabled.
rect[4 floats]
Geometry rectangle (default = 0 0 1 1). The four values represent normalized coordinates for the left, bottom, right and top sides of the geometry rectangle. To flip the image horizontally use rect 1 0 0 1 or to flip vertically use rect 0 1 1 0 .
outputs[int]
7.0.0
Number of texture outputs (default = 1). Texture outputs correspond to gen patcher outs.
out_name[symbol]
read-only
Output texture name
inputs[int]
Input count (default = 2)
gen[symbol]
The name of the gen patcher to use.
exportfolder[symbol]
Sets the folder to export gen patchers into when using the exportcode message.
dimscale[2 floats]
The output dimension scaling factor of the output (default = 1 1). Useful for upsampling or downsampling texture output.
output.dim = input.dim*dimscale
dim[2 ints]
The texture output dimensions when adapt is disabled (default = 256 256)
depth[float]
The depth or z-offset for the slab geometry. (default = 0.0)
colormode[symbol]
Texture color mode (default = argb)
Possible values:
'argb'
'uyvy'
adapt[long]
Enable adapt to input (default = 1). When enabled the texture output dimensions will match the input dimensions.
activeinput[int]
The current input used for texture and matrix messages (default = 0). Useful when calling input messages from Java or JavaScript.
OB3D Attributes
Common Box Attributes
annotation[symbol]

fontface[int]
Sets the type style used by the object. The options are:
plain
bold
italic
bold italic
Possible values:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
fontname[symbol]
Sets the object's font.
fontsize[float]
Sets the object's font size (in points).
Possible values:
'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'

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]
You can override the default appearance of a user interface object by assigning a JavaScript file with code for painting the object. The file must be in the search path.
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'

exportcode
Export a gen patcher as shader code. With no arguments, jit.gl.pix will export a standard Jitter JXS shader file with GLSL code. The optional arguments can be either 'jxs' or 'webgl' or 'isf'.
In the 'webgl' case, jit.gl.pix will export an .html file suitable for loading in a
WebGL context
. The code uses
TWGL
as a helper library and requires the
twgl-full.min.js
file be in the same directory as the exported html file.
In the 'isf' case, jit.gl.pix will export a .fs fragment shader suitable for loading in a
ISF (Interactive Shader Format) context
