When using image scale attributes in layouts (sample attached),

<FIELD
 NAME="__USR_CLR_ImageScale"
 TOP="0"
 LEFT="0"
 WIDTH= "600"
 HEIGHT="20"
 FONT_NAME="Geneva"
 FONT_SIZE="12"
>


and the image is scaled, real, or rapport size in dimension size,


then we show the scale information in the export preview and document.
