Recommended Posts

get image from clipboard, but _GDIPlus_ImageSaveToFile loss image quality

#include <Clipboard.au3>
#Include <GDIPlus.au3>
_SaveClip(@ScriptDir & "\XXX.jpg")
Func _SaveClip($sFile)
    If _ClipBoard_IsFormatAvailable($CF_BITMAP) <> 1 Then Return SetError(1, 0, 0)
    If _ClipBoard_Open(0) <> 1 Then Return SetError(2, 0, 0)
    If @error Then SetError(3, 0, 0)
    $hBitmap = _ClipBoard_GetDataEx($CF_BITMAP)
    If IsPtr($hBitmap) = 0 Then Return SetError(4, 0, 0)
    $hImage = _GDIPlus_BitmapCreateFromHBITMAP($hBitmap)
    If @error Or IsPtr($hImage) = 0 Then
        Return SetError(5, 0, 0)
    If _GDIPlus_ImageSaveToFile($hImage, $sFile) = False Then
        Return SetError(6, 0, 0)
        Return SetError(0, 0, 1)
EndFunc   ;==>_SaveClip

please post a sample

thanks any help

well after you explain why do you save it to JPG "XXX.jpg" then someone probably can make sense of your request for this problem.

There are those that believe that the perfect heist lies in the preparation.
Some say that it’s all in the timing, seizing the right opportunity. Others even say it’s the ability to leave no trace behind, be a ghost.

Try this

;coded by UEZ 2011
#include <clipboard.au3>
#include <gdiplus.au3>
#include <guiconstantsex.au3>
#include <windowsconstants.au3>

$msgb = MsgBox(4, "Clipboard to GUI", "Ready to copy an image from clipboard to GUI?")
If $msgb <> 6 Then Exit

If Not _ClipBoard_Open(0) Then Exit _WinAPI_ShowError ("_ClipBoard_Open failed")
$hMemory = _ClipBoard_GetDataEx($CF_BITMAP)
If $hMemory  = 0 Then Exit _WinAPI_ShowError ("_ClipBoard_GetDataEx failed")

$hBitmap = _GDIPlus_BitmapCreateFromHBITMAP($hMemory)
If $hBitmap = 0 Then Exit _WinAPI_ShowError ("_GDIPlus_BitmapCreateFromHBITMAP failed")

$iWidth = _GDIPlus_ImageGetWidth($hBitmap)
$iHeight = _GDIPlus_ImageGetHeight($hBitmap)

$hGUI = GUICreate("Show Image from Clipboard", $iWidth, $iHeight, -1, -1, $WS_POPUP, $WS_EX_TOPMOST)
GUISetState(@SW_SHOW, $hGUI)

$hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
_GDIPlus_GraphicsDrawImage($hGraphic, $hBitmap, 0, 0)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            _GDIPlus_ImageSaveToFile($hBitmap, @ScriptDir & "ImageFromClipboard.png")

Image will be save in lossless PNG format!

For the JPG best quality you can use these lines:

Local $sCLSID = _GDIPlus_EncodersGetCLSID("JPG")
Local $tParams = _GDIPlus_ParamInit(1)
Local $tData = DllStructCreate("int Quality")
DllStructSetData($tData, "Quality", 100)
Local $pData = DllStructGetPtr($tData)
_GDIPlus_ParamAdd($tParams, $GDIP_EPGQUALITY, 1, $GDIP_EPTLONG, $pData)
Local $pParams = DllStructGetPtr($tParams)
$save = _GDIPlus_ImageSaveToFileEx($hBitmp, @ScriptDir & "ImageFromClipboard.jpg"), $sCLSID, $pParams)
