2.1.1174 Part 1 Section 19.5.88, to (To)
For additional notes that apply to this portion of the standard, please see the notes for rCtr, §19.5.62(a) .
a. The standard states that the x attribute and the y attribute describe coordinates.
PowerPoint uses these attributes to specify the slide size percentage change when the to element is parented by the animMotion element, and the animated object size percentage change when the to element is parented by the animScale element.
b. The standard states that the x and y attribute values are defined as simple type ST_Percentage.
When used in animMotion, the attributes, x and y, are values of slide percentage and the valid range is between -2147483625 and 2147483625. When used in animScale, the attributes, x and y, are values of size percentage and the valid range is between 0 and 2147483625.
If the x or y values are less than -16384000 or greater than 16384000 there will be some loss of precision due to internal calculations.
