iflPCDO(3)

NAME
     iflPCDO - Kodak Photo CD Overview Pac file format

DESCRIPTION
     This IFL format is used to access image files stored in the Kodak Photo
     CD Overview Pac format.  Every Kodak Photo CD contains a file in this
     format called "overview.pcd"; this file contains a low resolution
     representation of each image on the Photo CD.

     The inherited iflFile member functions setCurrentImg(), getCurrentImg(),
     and getNumImgs() can be used to select and query the number of images and
     the current image index.  Note that iflPCDO's indices start at 0 whereas
     the Photo CD Image Pac file names start at 1; so, for example, the image
     in the Image Pac file img0010.pcd is at index 9 in the iflPCDO.

     The orienation of the images in a PCDO file are determined by the
     orientation of the image contents on the original film, and may be
     different for each image in the Overview Pac.  The orienation for a given
     image will always be the same as that of the corresponding Image Pac
     file.  See the iflPCD man page for more information about the orientation
     of Photo CD images.  The color model of an iflPCDO is ilRGB.

     The initial image index may be selected by appending :<n> to the filename
     passed to iflFile::open(), where <n> is the index of the desired image.
     The default image index is 0.

     IFL's access to a Kodak Photo CD Overview Pac file is read-only; it does
     not support creation or modification of Kodak Photo CD files.
