TextItemGetScale

This function allows retrieval of the scale or size of a text item.

Syntax

float textItemGetScale ( textitem textitem )             

Required Arguments

• textitem: The text item you wish to retreive the scale of

Returns

Returns a floating point of the scale of the text. 1.0 is around 12pt.

Example

This example retreives the scale of the 'theTextitem' text item, and if it is too small it enlarges it so it is more visible.

scale = textItemGetScale ( theTextitem )  --get the scale of theTextitem and define it as 'scale'
if scale < 0.5 then --if the scale is smaller than 0.5
    textItemSetScale ( theTextitem, 1.0 ) --then restore it to default size, 1.0.
end
