IO

The IO module provides image file input and output. Notably:

• if enabled at compilation time, yayi supports HDF5
• extended support of TIFF (8, 16, 32 bits images)
• extented support of PNG (16 bits images)
• generic RAW image

Reference

YayiIOPython.image_from_numpy((object)array) → Image :

returns a new Yayi image with the same dimension, size, type and content as the provided array. The values of the array are copied

C++ signature :

yayi::IImage* image_from_numpy(_object*)

YayiIOPython.image_to_numpy((Image)image) → object :

returns a numpy array representation of the image (no copy is performed)

C++ signature :

boost::python::handle<_object> image_to_numpy(yayi::IImage*)

YayiIOPython.readJPG((str)arg1) → Image :

(filename) : returns the specified Jpeg image

C++ signature :

yayi::IImage* readJPG(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >)

YayiIOPython.readPNG((str)arg1) → Image :
