simSetVisionSensorImg

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

C++ synopsis

int simSetVisionSensorImg(int sensorHandle, const unsigned char* img, int options, const int* pos, const int* size)

Arguments

• sensorHandle: handle of the vision sensor object
• img: 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]

Return

• -1 if operation was not successful
