Meta-imaging
The jit.eclipse object performs meta-imaging on two 4-plane char input matrices.
A jit.eclipse object divides a matrix sent into the left inlet into a grid with a specified number of rows and columns. Each box in the grid contains a scaled-down representation of the overall matrix. Each box is then tinted so that the overall image resembles a second matrix (sent into the right inlet). If the same image is used in both inputs, the result is a self-similar (or meta-) image.
Additional features such as threshold inversion, scalar tinting, and a choice of additive or multiplicative tinting are supported. There are also four modes that switch between color and monochrome treatment of the two matrices.
| Name | IOProc | Planelink | Typelink | Dimlink | Plane | Dim | Type |
| in2 | resamp | 1 | 1 | 1 | 4 | 1 | char |
| out | n/a | 1 | 1 | 1 | 4 | 1 | char |
| Name | Type | g/s | Description |
|---|---|---|---|
| blue | float | The amount of additional scaling applied to the blue channel (plane 3) of the output matrix (default = 0.) | |
| columns | int | The number of columns in the meta-image (default = 1) | |
| green | float | The amount of additional scaling applied to the green channel (plane 2) of the output matrix (default = 0.) | |
| inv | int | Invert color flag (default = 0) When the flag is set, RGB attributes are inverted in regions of the output image that are inverted. | |
| mode | int | Color mode by which the object tints the output matrix (default = 0 (both matrices color)) 0 = both matrices are color 1 = matrix 1 is converted to greyscale 2 = matrix 2 is converted to greyscale 3 = both matrices are converted to greyscale |
|
| op | int | The mathematical operation used for tinting (default = 0 (addition)) 0 = addition 1 = multiplication |
|
| red | float | The amount of additional scaling applied to the red channel (plane 1) of the output matrix (default = 0.) | |
| rows | int | The number of rows in the meta-image (default = 1) | |
| thresh | float | The threshold luminosity value around which grid regions in the meta-image are inverted in color (default = -1.01) | |
| tint | int | Tint mode flag (default = 1) When the flag is set, tinting is based on the second input matrix. |
