A filename is composed of the names of all the parts that make an object unique. Those parts are:
Those five pieces of information are joined together to make a filename in the following way:
object + geometry + shading + “pg” + page index + “p” +project number
So using the example values you would get:
“obj1geo2shd3pg1p99” or “OOOgggSSSpg1p99”
Note the fixed text “pg” and “p” are always placed in front of the page and project numbers, respectively.
The extension, (.jpg, .png, etc.) is determined by the chosen image format. (See the Geometry Editor’s Rendering and Re-Rendering)
The default format is ‘png’ so in this example the file would be:
“obj1geo2shd3pg1p99.png” or “OOOgggSSSpg1p99.png”
The names of an object, geometry, or shading can be set to any unique name you choose by editing the name text box in the Quick Properties Editor object,geometry or shading tab or in the respective item’s editor.
The page index is the page position in the page list. In future this may be changed to use the page name.
The project number is automatically set in the Project Option’s ‘Project Number’ field. It can be edited there as well.
If the ‘unique includes’ object is un-checked, then the page index is omitted from the filename. This allows the same file to be used on multiple pages in the same project in cases where the ‘include on’ other pages option is used. E.g. “obj1geo2shd3p99.png”
If the ‘unique clones’ object is un-checked, then the object name is omitted from the filename. This allows the same file to be used for multiple clones (objects with shared geometries) in the same project. E.g. “geo2shd3pg1p99.png”
The settings ‘unique includes’ and ‘unique clones’ can be found in the object editor’s component tab. The default setting is ‘checked’ (i.e., unique) for both. If you un-check them you are asserting the images are in fact the same. If they have different backgrounds or rotations, etc., you may see unexpected results because the same image will be used in all instances.
