MrKris1224 Posted February 23, 2014 Share Posted February 23, 2014 Hi. I know I ask a lot of questions. This is very important. How to convert 256-color image to 16-color image?? Of course, using autoit. Link to comment Share on other sites More sharing options...
Malkey Posted February 23, 2014 Share Posted February 23, 2014 This example is taken from the _GDIPlus_BitmapCloneArea function in the help file of AutoIt version 3.3.10.2 or greater. However, the $iFormat parameter is changed to $GDIP_PXF16RGB565, and the file extension in the ShellExecute command is corrected. #include <GDIPlus.au3> #include <ScreenCapture.au3> Example() Func Example() Local $hBitmap, $hClone, $hImage, $iX, $iY ; Initialize GDI+ library _GDIPlus_Startup() ; Capture 32 bit bitmap $hBitmap = _ScreenCapture_Capture("") $hImage = _GDIPlus_BitmapCreateFromHBITMAP($hBitmap) ; Create 24 bit bitmap clone $iX = _GDIPlus_ImageGetWidth($hImage) $iY = _GDIPlus_ImageGetHeight($hImage) $hClone = _GDIPlus_BitmapCloneArea($hImage, 0, 0, $iX, $iY, $GDIP_PXF16RGB565) ; $GDIP_PXF24RGB) ; Save bitmap to file _GDIPlus_ImageSaveToFile($hClone, @MyDocumentsDir & "\GDIPlus_Image.bmp") ; Clean up resources _GDIPlus_ImageDispose($hClone) _GDIPlus_ImageDispose($hImage) _WinAPI_DeleteObject($hBitmap) ; Shut down GDI+ library _GDIPlus_Shutdown() ShellExecute(@MyDocumentsDir & "\GDIPlus_Image.bmp") EndFunc ;==>Example Link to comment Share on other sites More sharing options...
MrKris1224 Posted February 23, 2014 Author Share Posted February 23, 2014 Unfortunately does not work :( The picture is the same as our original Link to comment Share on other sites More sharing options...
UEZ Posted February 23, 2014 Share Posted February 23, 2014 (edited) Try $GDIP_PXF04INDEXED instead. Or look to the _GDIPlus_BitmapConvertFormat function in the help file (runs properly on 3.3.11.3+).
