Regular API function

simGetScaledImage / sim.getScaledImage

Description	Generates a scaled-up or scaled down version of the input image. See also sim.transformImage, sim.loadImage, sim.saveImage and sim.setVisionSensorImg.
C/C++ synopsis	simUChar* simGetScaledImage(const simUChar* imageIn,const simInt* resolutionIn,const simInt* resolutionOut,simInt options,simVoid* reserved)
C/C++ parameters	imageIn: a pointer to rgb or rgba values of the input image. resolutionIn: the resolution of the input image. resolutionOut: the desired resolution of the output image. The values will be replaced by the effective resolution of the output image options: bit-coded: bit0 set (1): the input image is rgba, otherwise it is rgb bit1 set (2): the returned image is rgba, otherwise it is rgb bit2-3: 0:ignore aspect ratio, 4:keep aspect ratio (the effective resolution of the returned image will be different), 8:keep aspect ratio by expanding (the effective resolution of the returned image will be different) bit4 set (16): no smooth transformation reserved: Reserved for future extension. Set to nullptr.
C/C++ return value	nullptr if operation was not successful, otherwise a buffer containing the output image data. The user is in charge of releasing the buffer with simReleaseBuffer.
Lua synopsis	buffer imageOut,int[2] effectiveResolutionOut=sim.getScaledImage(buffer imageIn,int[2] resolutionIn,int[2] desiredResolutionOut,int options)
Lua parameters	Similar to the C-function counterpart
Lua return values	Similar to the C-function counterpart
Python synopsis	bytes imageOut,list effectiveRolutionOut=sim.getScaledImage(bytes imageIn,list resolutionIn,list desiredResolutionOut,int options)
