C 3: Creating Export and Publish Services
HAPTER
A single toggle entry controls whether users can select measurement units:
hidePrintResolution = Boolean
The rest of the service table entries that restrict existing functionality in the dialog come in positive and
negative forms; that is, you can list the features to be included, or you can list the features to be excluded.
For each such pair, you can provide only one of the entries, not both. If you provide neither, all default
elements in that category appear.
For example, you can choose which of the built-in sections to display in the dialog. If you use the positive
form, you list the sections to be shown:
showSections = { 'fileNaming', 'imageSettings' },
This causes the File Naming and Image Sizing sections to be visible, and hides all of the other built-in
sections. If you use negative form, you list the sections to be hidden. For example, this hides the Export
Location section, and shows all other built-in sections:
hideSections = { 'exportLocation' },
These are the service-table entry pairs for each type of restriction:
Restriction
File formats
Color spaces
Service table entries
allowFileFormats = { 'format'[, ...] },
disallowFileFormats = { 'format'[, ...] },
allowColorSpaces = { 'colorspace'[, ...] },
disallowColorSpaces = { 'colorspace'[, ...] },
Customizing the Export and Publishing Manager dialogs 56
When true, the options for sizing in the Image Sizing section
are shown only in pixel units; all mention of print units such as
inches, centimeters, and pixels-per-inch are hidden. Default is
false.
