Capturing screen into image

[Matt Maier]

This is the script I use to capture screenshots from particular areas

*on* snapCaptureButtMouseUp pLine

*-- clicked in node details to capture a screenshot from the previously
committed captureArea rect*

*-- set the loc of stack "captureArea" to -1000,-1000*

*-- close stack "captureArea"*

*-- should already be closed*

*-- export snapshot from rect sCaptureAreaGeometry["captureAreaRect"] to
image "figureHolder" stack "nodeDetails"*

*put* the effective filename of this stack into tPath

*set* the itemDelimiter to slash

*put* "temp/screenshot.gif" into item -1 of tPath

*export* snapshot from rect sCaptureAreaGeometry["captureAreaRect"] to file
tPath as GIF

*set* the filename of image "figureHolder" stack "nodeDetails" to tPath

*-- size the image*

*put* the rect of field "editData" stack "NodeDetails" into tQuery["maxRect"
]

*put* the long id of image "figureHolder" stack "NodeDetails" into tQuery[
"longID"]

*put* fitImageToConstraint(tQuery) into tGimme

*set* the width of image "figureHolder" stack "NodeDetails" to tGimme[
"width"]

*set* the height of image "figureHolder" stack "NodeDetails" to tGimme[
"height"]

*set* the loc of image "figureHolder" stack "NodeDetails" to tGimme["center"
]

*-- the clear button can be show now*

*set* the visible of button "clearImgButt" stack "NodeDetails" to true

*set* the visible of button "expandImgButt" stack "NodeDetails" to true

*put* the cNodeDetails of stack "NodeDetails" into tDeets

*put* empty into tDeets[pLine]["new"]

*put* true into tDeets["newFigure"]

*-- put "screenshot" into tDeets[pLine]["new"]["copyFrom"]*

*put* tPath into tDeets[pLine]["new"]["copyFrom"]

*put* uuid("random") into tUUID

*put* tUUID & ".gif" into tDeets[pLine]["new"]["newName"]

*set* the cNodeDetails of stack "NodeDetails" to tDeets

*end* snapCaptureButtMouseUp
