EROIC16::SetPixel

Allows writing a single pixel value in the ROI or image.

Namespace: Euresys::Open_eVision

[C++]

void SetPixel(
   EC16 value,
   int x,
   int y
)

Parameters

value

value to set the pixel to.

x

Offset of the pixel on the x axis.

y

Offset of the pixel on the y axis.

Remarks

Although coordinates outside of the ROI can be supplied, this function will raise an error condition if the coordinates are outside of the top parent image.

It should be noted that calling this function several thousand times can be slow. The recommended way to access pixel content in an image or ROI is to use the EBaseROI::GetImagePtr and EBaseROI::SetImagePtr functions. For BW8 images/ROIs, using the C++ API only, it is possible to access pixels data faster through an intermediate object: EBW8PixelAccessor.
