In 4th Dimension, you can actually perform Arithmetic functions with pictures to resize a picture and get the size (dimensions) you want.

A list of picture operators is available at:

For example, if you wanted to resize a picture so that its width is 1024, you could use the following code:

PICTURE PROPERTIES(PixVar;width;height)
If (width>1024)
 $Div_Value:=1024/width
 PixVar:=PixVar*$Div_Value
End if
