Regular API function

simReadTexture / sim.readTexture

Description	Retrieves the RGB data (or a portion of it) related to a specific texture. See also sim.getTextureId, sim.writeTexture and sim.createTexture.
C/C++ synopsis	simChar* simReadTexture(simInt textureId,simInt options,simInt posX,simInt posY,simInt sizeX,simInt sizeY)
C/C++ parameters	textureId: the ID of the texture. See also simGetTextureId. options: reserved for future functionality. Set to zero. posX / posY: the x/y position of the texture portion to retrieve. Set to 0/0 to retrieve the full texture sizeX / sizeY: the x/y size of the texture portion to retrieve. Set to 0/0 to retrieve the full texture
C/C++ return value	The texture data, or nullptr in case of an error. The texture data contains RGB values between 0-255 (3 bytes per pixel). The user is in charge of releasing the returned buffer with simReleaseBuffer.
Lua synopsis	buffer textureData=sim.readTexture(int textureId,int options,int posX=0,int posY=0,int sizeX=0,int sizeY=0)
Lua parameters	Similar to the C-function counterpart
Lua return values	Similar to the C-function counterpart
Python synopsis	bytes textureData=sim.readTexture(int textureId,int options,int posX=0,int posY=0,int sizeX=0,int sizeY=0)
