GDI+ text stroke effects

Recommended Posts

marcoauto

Ciao,

Is there a function to create a stroke text?

I have found the solution to fill the text with a texture, to make a shadow and to make a text with glow , but I can't reproduce the stoke effect.)

I have attached an example image of what I would like to reproduce

I have tried to adapt this script of Malkey but with no result

The Malkey script is this (I have edit some line) and the original post is here:

If you change the font then _GDIPlus_BitmapCloneArea (line 57) needs to be adjusted appropriately.

      Just press the lmb and move your mouse. When lmb is released you can adjust the size of the window by dragging the white rectangle to any direction. Rmb will move the marked area.
      Press ESC to get the coordinates of the marked region.
      If you have any improvements, please post it here.
       
      Tested on Win10 x64 only.

      I was looking around the help file and I came across _GDIPlus_GraphicsDrawRect and _WinAPI_DrawLine and I seem to be having the same "problem" where every time it draws into a window and you lose or gain focus it has to redraw itself. Is there anyway around this? 
      #include <WindowsConstants.au3> #include <WinAPI.au3> #Include <GDIPlus.au3> _GDIPlus_Startup() Run("notepad.exe") $hWnd = WinWait("Untitled") $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hWnd) $Color = 0xFFFF0000 $hPen = _GDIPlus_PenCreate($Color, 2) For $i = 1 To 10 _GDIPlus_GraphicsDrawRect($hGraphic, 200, 200, 25 ,25, $hPen) ToolTip($i) Sleep(1000) Next _WinAPI_RedrawWindow($hWnd, 0, 0, $RDW_INVALIDATE + $RDW_ALLCHILDREN) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_PenDispose($hPen) _GDIPlus_Shutdown()

      I have a situation where I am repeatedly capturing a region of the screen and feeding it into Tesseract OCR.  Since the OCR is a relatively slow operation, I would like to create an in memory cache of the ocr results.  An ideal hash key for this cache would be a checksum of the captured image.  With this I could capture the region, checksum it, and then only if I don't get a cache hit I would write the image out to disk for external OCR.
      Now I know I can do this by saving the captured image out to disk, and then summing the disk file with _Crypt_HashFile().  But that's still slower than I would like, and it shouldn't be necessary.  Ideally, it should be possible to checksum the image data directly in memory so I don't have to go to disk at all.  In order to do that, I need a way to dump a representation of the image into a string  (or some equivalent).  Then I could use the _Crypt_HashData() function against that string to create my cache hash key.
      Googling around I found an article here that shows a way to convert an image object to a byte array using System.Drawing.  This was the closest thing I found to what I'm trying to do.  I don't know if that method could be used from within AutoIT, or if perhaps there may be a better way I don't know about.  If someone could give me a shove in the right direction it would be a big help.  Thanks!
