MvGulik Posted December 13, 2010 Share Posted December 13, 2010 (edited) Just developing and testing a parts in a current project.Needed to draw some dots in a image for previewing/debugging. But there seems to be no direct drawdot function.Drawing with _GDIPlus_GraphicsDrawLine($hGraphic, $i1, $i2, $i1+1, $i2+1, $hPen) works.But thats one dot to much. And with ", $i1+0, $i2+0," I get on dot to less. Or no dots at all.Any know alternative's for drawing dots with GDIPlus UDF's ?- like to know for general testing purposes. (as final code in this case will probably just dump the used data as raw image data.)- could be something local. if I recall correctly.---[e:1]---Used(stripped-down) code.#include <WinAPI.au3> #include <GDIPlus.au3> _CreateImage('ignored', 'imageout.png', 100, 100) Exit Func _CreateImage($aMap_Date, $filename, $iW = 32, $iH = 32, $iColor = 0xFFFF00FF) #forceref $aMap_Date ;; setup Local $hBMP = _WinAPI_CreateBitmap($iW, $iH, 1, 32) _GDIPlus_Startup() Local $hImage1 = _GDIPlus_BitmapCreateFromHBITMAP($hBMP) Local $hGraphic = _GDIPlus_ImageGetGraphicsContext($hImage1) _GDIPlus_GraphicsClear($hGraphic, $iColor) Local $hPen = _GDIPlus_PenCreate() ;; draw Local $iTmp = 1 For $i1 = 0 To 20 Step 5 ;; $iW - 1 For $i2 = 0 To 20 Step 5;; $iH - 1 _GDIPlus_GraphicsDrawLine($hGraphic, $i1, $i2, $i1 + $iTmp, $i2 + $iTmp, $hPen) Next Next ;; save to image _GDIPlus_ImageSaveToFile($hImage1, $filename) ;; cleanup _GDIPlus_PenDispose($hPen) _GDIPlus_ImageDispose($hImage1) _GDIPlus_GraphicsDispose($hGraphic) _WinAPI_DeleteObject($hBMP) _GDIPlus_Shutdown() EndFunc Edited December 13, 2010 by MvGulik "Straight_and_Crooked_Thinking" : A "classic guide to ferreting out untruths, half-truths, and other distortions of facts in political and social discussions.""The Secrets of Quantum Physics" : New and excellent 2 part documentary on Quantum Physics by Jim Al-Khalili.
