These are very common tasks when programming e.g. scientific visualizations in Python using PyQt4 as the GUI library.Here are some key features of "qimage2ndarray":?’A· Supports conversion of scalar and RGB data, with arbitrary dtypes and memory layout, with and without alpha channels, into QImages (e.g. for display or saving using Qt).?’A· Using a tiny C++ extension, qimage2ndarray makes it possible to create ndarrays that are *views* into a given QImage's memory.?’A· This allows for very efficient data handling and makes it possible to modify Qt image data in-place (e.g. for brightness/gamma or alpha mask modifications).?’A· `Masked arrays`_ are also supported and are converted into QImages with transparent pixels.?’A· Supports value scaling / normalization to 0..255 for convenient display of arbitrary NumPy arrays..#md5=1f59c1c42395709a58c43ed74a866375
