4.9 The Document Attributes

The Document Attributes dialog is used to get a quick overview of the settings and attributes of the active document.

Most properties can be edited by double-clicking or by clicking the Edit-button and can be deleted by clicking the paper basket. But not all are editable or deletable. Some can only be edited and some can only be deleted.

The document tab shows always the following properties:

• the size
• the working mode (see chapter 2.11)
The Attributes Dialog is the only way to switch from the picture mode to the document mode explicitly. The other way round from the document mode to the picture mode is only possible, if the first layer in the document is an image having the same size as the document.
• the ICC profile
The ICC color profile is used to define the color space of the document (see chapter 7.6.15).
• Document Information and EXIF data
These points give you access to most important metadata (XMP, IPTC and EXIF, see chapter 2.14). A double-click allows you to quickly access Document Information (see chapter 7.4.93).
• position and size of the lasso
If there is a lasso, its size and position are shown. Double-clicking this entry allows to change the lasso size numerically.
• baseline grid
Baseline Grid allows to overlay the pages of the document with a line raster. A paragraph can be aligned to this raster by using "Text in Register" (see chapter 6.2.13, "The Tool Settings Of The Text Tool", subpoint "Paragraph Settings"). This results in a better looking text, if there are multiple columns or both sides of a sheet of paper are used for printing.
• Antialiasing
Antialiasing sets the default antialiasing of a document’s layers when displaying, printing, or saving. If the value is set to Default, the global setting Antialias (see chapter 7.2.16) is used. Layers also have their own antialiasing setting (see chapter 4.11).
• Cryptomatte
This entry only appears if a loaded OpenEXR contains cryptomatte data. Cryptomatte data is usually created by 3D render programs and is used to create masks for the individual objects in a scene.
To create a mask, simply press the New... button and the mask creation dialog will appear. If the file contains several Cryptomatte masks, you can use Cryptomatte to choose from which of these you want to create a mask. The image parts for which a mask can be created are then listed under Objects. You can also create a common mask for several objects by selecting several entries in the object list. You can do this with the usual modifier keys: Ctrl (Windows) or Command adds another object or removes one, the Shift key adds ranges.
You can then turn the newly created layer into a mask (see chapter 4.7 "Layer List > The thumbnail") or a layer mask (see chapter 7.5.14) or assign a work to it (see chapter 2.9 "Adjustment Layers" and chapter 7.5.13 "Modify Adjustment Layer").

Beside that a document often contains print options (see chapter 5.8).

At the bottom of the dialog there is also an export and quick export function that exports all pages and the layers on them if necessary (see chapter 4.12).
