char _image_module_frombyte__doc__[] =
"frombyte(A, isoutput)\n"
"\n"
"Load the image from a byte array.\n"
"By default this function fills the input buffer, which can subsequently\n"
"be resampled using resize. If isoutput=1, fill the output buffer.\n"
"This is used to support raw pixel images w/o resampling."
;
Py::Object
_image_module::frombyte(const Py::Tuple& args) {
_VERBOSE("_image_module::frombyte");
args.verify_length(2);
Py::Object x = args[0];
int isoutput = Py::Int(args[1]);
PyArrayObject *A = (PyArrayObject *)
PyArray_ContiguousFromObject(x.ptr(), PyArray_UBYTE, 3, 3);
if (A->dimensions[2]<3 || A->dimensions[2]>4)
throw Py::ValueError("Array dimension 3 must have size 3 or 4");
It looks to me like the return from PyArray_ContiguousFromObject needs
to be checked, and an exception thrown if necessary.
Unless I hear shortly that someone else is already fixing this, or that
I am misdiagnosing the problem, I will proceed. It may be that checking
for 3-D needs to be done earlier in the mpl python code as well, but it
certainly seems like it should be done here.
