in this box, you must be sure that the data that will be selected at run-time will not
contain any parentheses, as this would cause the task to fail. If you suspect that the
data may contain parentheses, you should use a Run script action task (see Run
Script Action Task Property) with a Strip() function to strip them out.

property box, you may use variables and data selections and let PlanetPress
Workflow interpret this information at run-time.

Monochrome compression: Select the compression to use for the monochrome
images. Flate compression is lossless, so no data is lost during compression. Flate
Mono works well on images with large areas of solid shades or repeating patterns,
such as screen shots and simple images created with paint or drawing programs.
CCITT typically yields the best compression of monochrome images. It is the
compression method developed for fax transmissions. Note that configurations that
were created with an earlier version of PlanetPress Workflow and that included
tasks set not to use any compression will by default be set to use the Flat
compression method.

Monochrome resolution: Select the resolution to use for monochrome images.

Grayscale compression: Select the compression to use for the grayscale images.
Flate is a lossless compression method, so no data is lost in the process. It works
well on images with large areas of single shades or repeating patterns, such as
screen shots and simple images created with paint or drawing programs. JPEG
removes image data and may reduce image quality, but may be suitable for
continuous-tone photographs containing more detail than can be reproduced
onscreen or in print. Since JPEG eliminates data, it can achieve much smaller file
sizes than Flate compression. Select Auto to let the application choose the best
compression method automatically. Note that configurations that were created with
an earlier version of PlanetPress Workflow and that included tasks set not to use
any compression will by default be set to use the Flate compression method.
l
Grayscale down sampling: Select the down sampling option. down sampling
reduces image size by breaking images down into small areas in which multiple
pixels are replaced by single pixels. The Grayscale resolution you enter in the
following box is used to control the down sampling process. Select None to prevent
grayscale down sampling . Select Average to average pixel shades in each sample
area and to replace the entire area with a pixel of the average shade. Select
