- Thanks to Hadmut Danisch of the University of Karlsruhe, who deciphered Kodak's
- Photo CD file format by reverse engineering, I have been able to put together a
- Photo CD viewer for the NeXT. The app ain't perfect and there still lurks a
- bug or two, but I wanted get it out to beat the Christmas rush. In addition to
- my source code for the user interface, I have included Hadmut's original
- software, hpcdtoppm (v0.3).
-
- I assume the directory structure for all Photo CDs are the same, but my
- experience is limited to quantity one. In particular, pCD assumes that at the
- volume root level there will be a file with the name overview.pcd, and a
- directory entitled images. Under this directory there are an indeterminate
- number of files, each with a name of the form imgnnnn.pcd, where nnnn is a four
- digit sequence number. If your Photo CD is structured differently, make
- appropriate changes to the Controller class.
-
- When pCD launches it requests a Photo CD volume name. Then by reading the
- overview.pcd file, it produces a window showing thumbnails of the images in the
- images directory. Each thumbnail is a button, which when clicked, reads and
- displays the base (512 x 768) size of the image. By looking at my code and
- Hadmut's program, you can modify pCD to bring up all the image sizes available.
- They are:
-
- base/16 128 x 192
- base/4 256 x 384
- base 512 x 768 (supported by pCD)
- 4base 1024 x 1536
- 16base 2048 x 3072
-
- If I get time next year, I may add support for other sizes. If you beat me to
- it, please share your improvements with the world. One other thing — although
- all thumbnails appear in landscape format, the selected images will be
- displayed appropriately.
-
- Once you open an image, you can:
-
- 1) Save it as a TIFF, EPS, or JPEG file.
-
- 2) Rubber-band out a rectangular region region of the image and copy it
- to the pasteboard. If you then issue a paste command, an new window will
- open containing the subimage. Alternately, you can paste the subimage into
- any application that accepts the above formats.
-
- 3) Print either just the image or the image with the enclosing window
- frame. Be careful! Only the Print and Cancel buttons work correctly.
- (Perhaps someone will finish off the printing code).

- Have fun!
