Save P Saving the Current Attributes as a "Property"

Save P Saving the Current Attributes as a "Property"

Initially PRIMER has no properties saved, so the saving button will show Save P
Once you click on it to save a property it will be updated to be SP i/j where i is the current property number j is the current total number of saved properties You can still click on the renamed SP i/j to save further properties.

Cycling through saved properties using and

Once you have saved one or more properties you can use the <= and => buttons to cycle between them. Cycling left ( <= ) reduces the property number, and right ( => ) increases it. It is possible to cycle backwards (left) to current property 0, which is explained below.

Property number 0, the "current" property

PRIMER always maintains a "current" property which is what you see on the screen, and this is given the special number 0.

When you navigate to a saved property i this effectively copies that saved set of attributes to the current one, and likewise whenever you save a property you make a copy of the current property 0.

If you have navigated to a saved property i and you subsequently do something which changes the appearance of the image on the screen, for example blanking something, then the current property number gets reset to 0, and the SP i/j button will be updated to show SP 0/j .

This is because the current property no longer matches the saved property i , so it is no longer true to say that you are at property i . (The saved property i is not affected by this change: remember that making a saved property current copies it to current property 0, and it is only this current property that has been updated.)
