Regular API function
simSetVisionSensorImg / sim.setVisionSensorImg
|
Description
|
Writes the image of a vision sensor (and applies any image processing via the vision callback functions). Make sure the vision sensor is flagged as external input. See also the other vision sensor related API functions |
C/C++
synopsis
|
simInt simSetVisionSensorImg(simInt sensorHandle,const simUChar* img,simInt options,const simInt* pos,const simInt* size) |
C/C++
parameters |
sensorHandle: handle of the vision sensor object
img: a buffer containing the image
options: options, bit-coded:
bit0 set (1): the provided image is a greyscale image (1 byte per pixel), otherwise an RGB image (3 bytes per pixel)
bit1 set (2): the provided image has one additional byte per pixel, as alpha channel (RGBA or greyscale+A)
pos: position of the image portion to write. Can be nullptr, which defaults to {0,0}
size: size of the image portion to write. Can be nullptr which defaults to {0,0}, which corresponds to {resolutionX,resolutionY}
