- There has been one new file format, Kodak PhotoCD, and one new command,
- convolve, added to Image Alchemy since the manual was printed. These
- are described below:
-
-
-
- Convolve -yf
-
- Purpose Applies any one of a number of convolutions to
- an image (such as sharpen and blur).
-
- Syntax -yf filename
-
- Comments The various convolutions that ship with Image
- Alchemy are found in the samples\ directory.
- The only two which ship with this version are
- sharpen and blur. Other convolutions will be
- downloadable from our BBS (+1 510 252 0929) as
- they become available (the filename to look for
- is filters.zip).
-
- Examples Convert the TIFF file image.tif to a TIFF file,
- called new.tif, sharpening it in the process:
-
- alchemy image.tif new.tif -t -yf samples\sharpen
-
-
- Convert the TIFF file image.tif to an HP-RTL
- file for the Novajet, scaling it to 2500x2550
- and bluring it:
-
- alchemy image.tif --r10 -yf samples\blur
- -X2500 -Y2550
-
-
-
- PhotoCD
-
- PhotoCD files are multi-resolution images
- produced by Kodak.
-
- Extensions .pcd
-
- Creator Eastman Kodak Company
-
- Used by Eastman Kodak Company
-
- Variations Reads single channel and 3 channel images.
-
- Limitations The full path to the PhotoCD file must be
- specified as the input file (e.g.,
- L:\photo_cd\images\img0001.pcd).
-
- Alchemy cannot write PhotoCD files.
-
- Comments The Alchemy overlay file, alchpcd.exe, is used
- by Image Alchemy when reading PhotoCD images.
- This file must either be in the same directory
- as alchemy.exe, or any directory in your path.
-
- Since PhotoCD files are multi-resolution images
- you may specify which resolution image you want
- Alchemy to read. The -Z option, followed by a
- number, is used to specify the desired
- resolution. Available resolutions are:
- 2: 192x 128
- 3: 384x 256
- 4: 768x 512
- 5:1536x1024
- 6:3072x2084
- The default is 3 (384x256).
-
- Alchemy automatically rotates the picture to
- the "correct" orientation (as was determined
- by the technician who recorded your PhotoCD),
- however, you can override this by using a
- second parameter after the -Z option. The
- second parameter can take on the following
- values:
- 0:don't rotate the image
- 1:flip image vertically
- 2:flip image horizontally
- 3:rotate image 180 deg (the same as both
- vertical and horizontal flip)
- 4:rotate image 90 deg CCW
- 5:rotate image 90 deg CCW and flip
- vertically
- 6:rotate image 90 deg CCW and
- flip horizontally
- 7:rotate image 90 deg CW (the same as
- rotating it 90 deg CCW and flipping both
- horizontally and vertically)
- The default is 0 (don't rotate the image).
-
- If you specify a -b as part of the command line
- Alchemy will read a Grayscale version of the
- image.
-
-
- Example
- To read the 768x512 size image and rotate it 90
- degrees counter-clockwise:
-
- alchemy L:\photo_cd\images\img0001.pcd -g
- -Z 3 4
