qimage.toTensor(tensor)

Fill the Tensor tensor with data from QImage qimage. Tensor tensor must have 2 or 3 dimensions. The first two dimensions must be equal to the image width and height respectively. The third dimension must be 1, 3, or 4 for monochromatic, rgb or rgba images. The qimage data will be converted to the desired format and stored into the tensor, each component being represented by a floating point number in range 0 to 1. This function returns the filled tensor.

qimage.toTensor(depth)

Create a tensor with data from image qimage. Argument depth must be 1, 3, or 4 for extracting monochromatic, rgb or rgba data. When depth is one, this function returns a two-dimensional tensor. Otherwise it returns a three-dimensional tensor with the third dimension equal to depth. The first two dimensions are always the image width and height.
