Header Information

[AndyB]

Hello,

Is it possible to just load header information from an image file? For example we're after a way of reading the dimensions, bit depth and number of unique colours of an image without loading the entire file. We're using the C++ API.

Thanks in advance.

The "ping" method will give you the dimensions and filesize without reading the image data. But it doesn't give you the bit depth or number of unique colours. I don't know if there's a way in IM to get them without reading the image.

The ping function is a starting point. Thanks for the help.
