UDF: _RegionSelector.au3

3 posts in this topic

#1 ·  Posted (edited)

Hey all, i needed something to let the user select a region on the screen, and then record it with GDI just had 2 problems, couldnt find no region selector around and how to get the actual Frame-rate, cause obviously Sleep function is as inaccurate as hell :-p
So i created this lil UDF that does both.
Credits to guinness for his help getting the close option to be gone >[Tread]

Functions:

_RegionselectorCalcFPS


_RegionselectorSetState
_RegionselectorGetPos
_RegionselectorOff
_RegionselectorOn



Example:

#include "_RegionSelector.au3"
_Example()
Func _Example()
    Local $iCapturedFrames = 0, $i, $iPausedTime = 0
    Local $aRegionSelector = _RegionSelectorOn()
    Sleep(500)
    Local $iStartTime = _RegionSelectorSetState($aRegionSelector, 2)

    ;Do some recording.
    For $i = 1 To 50
        $iCapturedFrames += 1
        Sleep(25)
    Next

    ;Pause.
    For $i = 0 To 10
        $iPausedTime += _RegionSelectorSetState($aRegionSelector, 3, 400)
    Next

    ;Record some more.
    For $i = 1 To 50
        $iCapturedFrames += 1
        Sleep(25)
    Next

    ;Stop recording.
    Local $iEndTime = _RegionSelectorSetState($aRegionSelector, 1, $iStartTime)
    _RegionSelectorOff($aRegionSelector, 1)

    MsgBox(64, '_RegionSelector.au3', _
            'Total time passed: ' & Round($iEndTime / 1000, 2) & 'seconds' & @LF & _
            'Frames recorded: ' & $iCapturedFrames & @LF & _
            'Frame delay: ' & _RegionSelectorCalcFPS($iEndTime, $iCapturedFrames, $iPausedTime, 2) & ' ms (for GIFs and such)' & @LF & _
            'FPS: ' & _RegionSelectorCalcFPS($iEndTime, $iCapturedFrames, $iPausedTime, 1, 2) & ' fps')
EndFunc   ;==>_Example

How do you display the "record" result ?

Thanks, i'm not sure i understand your question.

in the example function replace "$iCapturedFrames += 1" with your screencapturing function.

For my gif-recorder im just using GDI and count the output files with DirGetSize
