Hi Alejandro, thanks for the script. Again Scott found a neat trick! here is a slight adaption of your version that avoids that you wander off into the wrong direction and the image becomes unresponsive. ------------------------------------------ local lpoints,tClick,tFirstPoint -- based on Scott Rossi script for masking images local sMinX, sMinY on mouseDown put mouseH(),mouseV() into tClick put the points of me into lpoints put line 1 of lpoints into tFirstPoint put line 2 to - 1 of lpoints into tPointLIst filter tPointList without "" sort tPointList numeric ascending by item 1 of each put item 1 of line 1 of tPointList into sMinX sort tPointList numeric ascending by item 2 of each put item 2 of line 1 of tPointLIst into sMinY put "mouseDown" & cr & lpoints & cr & cr into fld 1 end mouseDown on mouseMove X,Y if tClick = "" then exit mouseMove put (X - item 1 of tClick,Y - item 2 of tClick) put (X - item 1 of tClick) + item 1 of tFirstPoint,(Y - item 2 of tClick) + item 2 of tFirstPoint into line 1 of lpoints if item 1 of line 1 of lpoints > sMinX then put sMinX into item 1 of line 1 of lpoints if item 2 of line 1 of lpoints > sMinY then put sMinY into item 2 of line 1 of lpoints set the points of me to lpoints end mouseMove on mouseUp put "" into tClick end mouseUp on mouseRelease put "" into tClick end mouseRelease ------------------------------------------ as usual watch for linebreaks.
