Operator Library: Base
The operator Coordinate_X provides the x coordinate of the input pixels at its output. Thus, each pixel at the input is replaced by its x-position in the image. The actual input pixel values are not used. The operator works as a counter which is incremented with every new pixel and is reset after the end of a line. The first pixel of each row will have coordinate zero.

The range of the input bit width is [1, 64]. For signed inputs, the range is [2, 64]. For unsigned color inputs, the range is [3, 63] and for signed color, the range is [6, 63]. |

The output bit width is automatically determined from the maximum image width i.e.

The use of operator Coordinate_X is shown in the following examples:
-
Example - Histogram thresholding
-
Examples - Shows the usage of operator Blob_Analysis_1D in line scan applications.

'Color Plane Separation Option 5 - Sequential Output with Advances Processing'
Example on separation of color planes. The RGB input is split into its component and sequentially output via one DMA channel. The splitting if performed by collecting same components in parallel words and reading with FrameBufferRandomRead.
-
Example - While image timing is provided by a generator the designs data flow can be analyzed.
-
Examples - Shows how to vertically mirror an image. Note the mirroring of the parallel words and the pixel.

'1D Shading Correction Using Block RAM'
Examples - The example shows an 1D shading correction. The correction values are stored in block RAM memory.
