Kodak Photo-CD (PCD)

 

General Description

Kodak Photo-CD allows you to have conventional photographs converted to Kodak's proprietary CD-ROM format. Not all CD-ROM drives can access Photo-CDs. You might want to contact Kodak for a full list of those that can. Each PCD file contains five scans of the same image at the resolutions listed below. Photo-CD files reside in the \PHOTO_CD\IMAGES\ directory on the CD-ROM and are named IMGxxxx. PCD, where xxxx is a four digit number ranging from 0001 to the number of images on the disk.

 

A sixth resolution (6144x4096) may be available on Photo-CD PRO disks. This is an extension to the standard, and resides in a different directory on the disk. PMView will use the information in PHOTO_CD\IPE\IMGxxxx\64BASE\INFO.IC when reading this resolution.

 

PMView Support

All five standard image resolutions and orientations are supported. When needed, the images will automatically be rotated without any extra memory overhead during decoding. The Photo-CD PRO extension (64 Base) is also supported.

 

PMView will prompt you for the desired resolution before loading an image. A default resolution can also be specified in the Preferences Notebook.

 

Thumbnails will be loaded from \PHOTO_CD\OVERVIEW.PCD if it is available. An option for automatically loading/showing the startup file \PHOTO_CD\STARTUP.PCD is not available. However, if required, it can be viewed simply by changing the directory.

 

Technical Information

Standard Photo CD image resolutions and memory needed for decoding:

 

192 x 128 73,728 bytes

384 x 256 294,912 bytes

768 x 512 1,179,648 bytes

1536 x 1024 4,784,128 bytes

3072 x 2048 19,070,976 bytes

6144 x 4096 75,694,080 bytes

 

 

The specified amount of memory needed for decoding includes the size needed for the Huffman tables and may therefore differ from the size reported by other programs.
