Operators
Operators
↑ aktive query value around
Syntax: aktive query value around src ?(param value)...? [→ definition]
Returns the input's pixel values for the region around the specified 2D point, within the manhattan radius.
The result is not an image.
Beware that the coordinate domain is 0..width|height, regardless of image location.
This operator is strict in its single input. The requested pixel region is materialized in memory.
| Input | Description |
|---|---|
| src | Source image |
| Parameter | Type | Default | Description |
|---|---|---|---|
| x | int | Physical x-coordinate of the pixel to query | |
| y | int | Physical y-coordinate of the pixel to query | |
| radius | uint | 1 | Region radius, defaults to 1, i.e. a 3x3 region. |
↑ aktive query value at
Syntax: aktive query value at src (param value)... [→ definition]
Returns the input's pixel value(s) at the given 2D point.
The result is not an image. It is a list of floating point numbers for a multi-band input, and a single floating point number otherwise.
Beware that the coordinate domain is 0..width|height, regardless of image location.
This operator is strict in its single input. The requested pixel is materialized in memory.
| Input | Description |
|---|---|
| src | Source image |
| Parameter | Type | Default | Description |
|---|---|---|---|
| x | int | Physical x-coordinate of the pixel to query | |
| y | int | Physical y-coordinate of the pixel to query |
Examples
| @1
|
aktive query value at @1 x 0 y 1

↑ aktive query values
Syntax: aktive query values src [→ definition]
Returns a list containing the input's pixel values.
The values are provided in row-major order.
The list has length "aktive query size <src>".
This operator is strict in its single input. The image is materialized in memory.
| Input | Description |
|---|---|
| src | Source image |
Examples
| @1
|
aktive query values @1
