Overall size of textures in a scene

[Mahmoodreza Aarabi]

Hey masters

I have a problem here, i want to get size of all textures that loaded in a scene in maya, paths are loaded from different directories.

there is any idea?

If you can gather the file nodes in the scene, can you then query their outSize attr values?

What do you mean by size? 

If file size, then use python os.stat() function

If you meant bitmap resolution, then there are multiple options. One trick is to create imagePlane and set it's file name - it should show tex res in its attributes.

for PNGs I had a snippet around:

def get_image_info(data):

    if is_png(data):

        w, h = struct.unpack('>LL', data[16:24])

        width = int(w)

        height = int(h)

    else:

        raise Exception('not a png image')

    return width, height

def is_png(data):

    return (data[:8] == '\211PNG\r\n\032\n'and (data[12:16] == 'IHDR'))

def GetRes(fName):

    data = None

    with open(fName, 'rb') as f:

        data = f.read()

    if is_png(data):

        return get_image_info(data)

    else:

        return (-1, -1)
