示例1: read_tiff_data
/*
This function sets the input directory to the directory of a given
page and determines information about the image. It checks
the image characteristics to determine if it is possible to convert
the image data into a page of PDF output, setting values of the T2P
struct for this page. It determines what color space is used in
the output PDF to represent the image.
It determines if the image can be converted as raw data without
requiring transcoding of the image data.
