  1. ciao, I need to scale an outlined GDI text in a GUI. The problem is that I can't do this. The outline is often out of the GUI I started from this script: https://www.autoitscript.com/autoit3/docs/libfunctions/_GDIPlus_PathTransform.htm that fit a string to windows and I changed $aBounds = _GDIPlus_PathGetWorldBounds($hPath) ;Get bounding rectangle of the path $aBounds = _GDIPlus_PathGetWorldBounds($hPath) ;Get bounding rectangle of the path with $aBounds = _GDIPlus_PathGetWorldBounds($hPath,$hMatrix,$hPen) ;Get bounding rectangle of the path with pen size but doesn't work so, I tried to change other thins, but nothing... Sometimes works, but if I change the string often result change This is my script: #include <GUIConstantsEx.au3> #include <GDIPlus.au3> #include <array.au3> Example() Func Example() Local $iW, $iH, $hGUI, $hGraphic, $hBrush, $hPen, $hPath, $hFamily, $tLayout, $hMatrix, $aBounds ; Create GUI $iW = 650 $iH = 300 $hGUI = GUICreate("GDI+", $iW, $iH) GUISetState(@SW_SHOW) ; Draw a string using path _GDIPlus_Startup() $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI) ;Create a graphics object from a window handle _GDIPlus_GraphicsSetSmoothingMode($hGraphic, $GDIP_SMOOTHINGMODE_HIGHQUALITY) ;Sets the graphics object rendering quality (antialiasing) ;~ _GDIPlus_GraphicsClear($hGraphic, 0xFF000000) $MergedImageBackgroundColor = 0x00000000 _GDIPlus_GraphicsClear($hGraphic, $MergedImageBackgroundColor) $hBrush = _GDIPlus_BrushCreateSolid(0xFFDD2200) $stroke_size = 15 $hPen = _GDIPlus_PenCreate(0xFFFFBB00, $stroke_size) ;stroke size in pixel $hPen2 = _GDIPlus_PenCreate(0xFFFFff00, 2) ;stroke size in pixel _GDIPlus_PenSetLineJoin($hPen,$GDIP_PENSETLINEJOIN_ROUND) $hPath = _GDIPlus_PathCreate() ;Create new path object ;~ $fSize = 20 $hFamily = _GDIPlus_FontFamilyCreate("Myriad Pro") ;Create font family object $tLayout = _GDIPlus_RectFCreate() ;Create string bounding rectangle X=0, Y=0 Local $hFormat = _GDIPlus_StringFormatCreate() _GDIPlus_PathAddString($hPath, "autoitForeverLollipop", $tLayout, $hFamily);, 0, $fSize, $hFormat) ;Add the outline of the string to the path ;~ _GDIPlus_PathAddString($hPath, $sText, $tLayout, $hFamily, 0, $fSize, $hFormat) ; Tranform Path to fit to window $aBounds = _GDIPlus_PathGetWorldBounds($hPath) ;Get bounding rectangle of the path $aPoints = _GDIPlus_PathGetPoints($hPath) ConsoleWrite($aBounds[0] & @CRLF) ConsoleWrite($aBounds[1] & @CRLF) ConsoleWrite($aBounds[2] & @CRLF) ConsoleWrite($aBounds[3] & @CRLF) ConsoleWrite($aPoints[$aPoints[0][0]][0] & " - " & $aPoints[1][0] & " + 2*" & $stroke_size & " = " & $aPoints[$aPoints[0][0]][0]-$aPoints[1][0]+2*$stroke_size & @CRLF) ;~ $aBounds[0] = $aBounds[0] $aBoundsNp = _GDIPlus_PathGetWorldBounds($hPath,0,$hPen) ;Get bounding rectangle of the path with pen ConsoleWrite($aBoundsNp[0] & @CRLF) ConsoleWrite($aBoundsNp[1] & @CRLF) ConsoleWrite($aBoundsNp[2] & @CRLF) ConsoleWrite($aBoundsNp[3] & @CRLF) ConsoleWrite($iW & " / 2 = " & $iW / 2 & @CRLF) ConsoleWrite("$ih / 2 = " & $iH / 2 & @CRLF) ;~ ConsoleWrite($iW & " $aBounds[2] = " & $iW / $aBounds[2] & @CRLF) ConsoleWrite($iW & " $aBoundsNp[2] = " & $iW / $aBoundsNp[2] & @CRLF) ConsoleWrite($iH & " $aBoundsNp[3] = " & $iH / $aBoundsNp[3] & @CRLF) ;~ _GDIPlus_GraphicsDrawPath($hGraphic, $hPath, $hPen) ;Draw path to graphics handle (GUI) ;~ _GDIPlus_GraphicsFillPath($hGraphic, $hPath, $hBrush) ;Fill path to graphics handle (GUI) $hMatrix = _GDIPlus_MatrixCreate() $iW = $iW - $stroke_size ;+ $stroke_size $iH = $iH - $stroke_size ConsoleWrite(" -$aBounds[0]+1*$stroke_size/72 = " & -$aBounds[0]+1*$stroke_size/72 & @CRLF) ConsoleWrite(" -1.8+1*$stroke_size/72 = " & -1.8+1*$stroke_size/72 & @CRLF) _GDIPlus_MatrixTranslate($hMatrix, -$aBounds[0]+2*$stroke_size/72, -$aBounds[1]+1*$stroke_size/72) ;Translate Matrix to the offset of the bounding rectangle ;~ _GDIPlus_MatrixTranslate($hMatrix, -1.59166666666667+0*($stroke_size/72), -$aBounds[1]+1*$stroke_size/72) ;Translate Matrix to the offset of the bounding rectangle ;~ _GDIPlus_MatrixScale($hMatrix, $iW / $aBounds[2], $iH / $aBounds[3], True) ;Scale Matrix _GDIPlus_MatrixScale($hMatrix, $iW / $aBounds[2], $iH / $aBounds[3], True) ;Scale Matrix _GDIPlus_PathTransform($hPath, $hMatrix) ;Translate and Scale Path $aBoundsNp = _GDIPlus_PathGetWorldBounds($hPath,0,$hPen) ;Get bounding rectangle of the path with pen ConsoleWrite($aBoundsNp[0] & @CRLF) ConsoleWrite($aBoundsNp[1] & @CRLF) ConsoleWrite($aBoundsNp[2] & @CRLF) ConsoleWrite($aBoundsNp[3] & @CRLF) ;~ _GDIPlus_GraphicsFillPath($hGraphic, $hPath, $hBrush) ;Fill path to graphics handle (GUI) _GDIPlus_GraphicsDrawPath($hGraphic, $hPath, $hPen) ;Draw path to graphics handle (GUI) _GDIPlus_GraphicsFillPath($hGraphic, $hPath, $hBrush) ;Fill path to graphics handle (GUI) ; Loop until the user exits.
