[SOLVED] Convert Bitmap image to JPG in memory

Recommended Posts

Hey

I'm not really familliar with GDI Plus , I am looking for how tocConvert a bitmap image to JPG in memory without saving it to disk

Because I want to send it later via TCP directly without using FileRead and other stuff ..

The only function I found is below but it saves the image in disk :(

Func SaveBmp2JPG($Bitmap, $sSave = "Converted.jpg", $iQuality = 20) ;coded by UEZ 2013
    If Not IsPtr($Bitmap) Then
        $Bitmap = _GDIPlus_ImageLoadFromFile($sFile)
        If @error Then Return SetError(1, 0, 0)
    EndIf
    Local $sCLSID = _GDIPlus_EncodersGetCLSID("JPG")
    Local $tParams = _GDIPlus_ParamInit(1)
    Local $tData = DllStructCreate("int Quality")
    Local $pData = DllStructGetPtr($tData)
    Local $pParams = DllStructGetPtr($tParams)
    DllStructSetData($tData, "Quality", $iQuality)
    _GDIPlus_ParamAdd($tParams, $GDIP_EPGQUALITY, 1, $GDIP_EPTLONG, $pData)
    If Not _GDIPlus_ImageSaveToFileEx($Bitmap, $sSave, $sCLSID, $pParams) Then Return SetError(2, 0, 0)
    Return True
EndFunc

what my code now looks like :

#include <ScreenCapture.au3>
#include <guiconstantsex.au3>
#include <gdiplus.au3>
#include <memory.au3>
#include <staticconstants.au3>


Global $ghGDIPDLL = $__g_hGDIPDll

 Example()
Func Example()

    _GDIPlus_Startup()
    Local $hHBmp = _ScreenCapture_Capture("") ;create a GDI bitmap by capturing my desktop
    Local $hBitmap = _GDIPlus_BitmapCreateFromHBITMAP($hHBmp) ;convert GDI bitmap to GDI+ bitmap
    _WinAPI_DeleteObject($hHBmp) ;release GDI bitmap resource because not needed anymore
    Local $hBitmap_Scaled2 = _GDIPlus_ImageResize($hBitmap,  @DesktopWidth / 1.5, @DesktopHeight / 1.5) ;resize image

SaveBmp2JPG($hBitmap_Scaled2,'Test.jpg',99) ; ===> Saving to disk ??


    _GDIPlus_Shutdown()

EndFunc   ;==>Example

Func SaveBmp2JPG($Bitmap, $sSave , $iQuality) ;coded by UEZ 2013
    If Not IsPtr($Bitmap) Then
        $Bitmap = _GDIPlus_ImageLoadFromFile($sFile)
        If @error Then Return SetError(1, 0, 0)
    EndIf
    Local $sCLSID = _GDIPlus_EncodersGetCLSID("JPG")
    Local $tParams = _GDIPlus_ParamInit(1)
    Local $tData = DllStructCreate("int Quality")
    Local $pData = DllStructGetPtr($tData)
    Local $pParams = DllStructGetPtr($tParams)
    DllStructSetData($tData, "Quality", $iQuality)
    _GDIPlus_ParamAdd($tParams, $GDIP_EPGQUALITY, 1, $GDIP_EPTLONG, $pData)
   If Not _GDIPlus_ImageSaveToFileEx($Bitmap, $sSave, $sCLSID, $pParams) Then Return SetError(2, 0, 0)
    Return True
 EndFunc

Thanks man but I don't think it's working :( , I tried to save the result image on hdd to debug and the filesize was 8kb with empty image .

And here I could not even put the functions WinAPI CreateStreamOnHGlobal() , _WinAPI_GetHGlobalFromStream() and _WinAPI_ReleaseStream() in the script!

@DrAhmed: Search the forum for "_GDIPlus_StreamImage2BinaryString" and you will find several examples how to use it in different scenarios.

You even replied here:

If the memory consumption of your script is permanetely increasing then you have probably a memory leak. This mostly occurs when you don't release GDI/GDI+ resources.

Btw, define "high usage". What is the size of your images which you send to this function?

@UEZ

The image size is really small arround 50KB , I set a low value for JPG quality and used image resize to reduce it .

that's what I am getting after few seconds of running the script :

Rp1y3tE.jpg

 

Edit : I am using this func to encode the stream data before sending them , can it be the reason ?

Are you calling the function in a loop or only one time? Is the memory consumption just high or is it increasing permanetely?

1- In a loop ( but I set the sleep(1000) )

2-   Increasing permanetely

Ok, then you doing something wrong in your loop as mentioned in post #8.

Show me that loop please.

6-12% is not that high but for Sleep(1000) it is.

 

I don't know what code is behind 

; Here I use TCPSend to send the data to my client

Have a look there.


Please don't send me any personal message and ask for support! I will not reply!

      hello Im wondering if it is possible to process image in autoit like this
      1. firstly there is colorfull wallpaper
      2. Fill all colors (exception rose color) - with white
      3. Fill rose color with black color
      I see Gdi functions have things to manipulate images

      GdipBitmapGetHistogram(), GdipBitmapGetHistogramSize() and 2 more GDI+ functions requires GDI+ v1.1 which means this will only run on Vista or higher operating systems.
      I hope the values are correct especially the value for luminosity.

      I'm creating a tool which automatically saves screenshots.  I've found that some images appear corrupt after saving.  I've narrowed the source down to screenshots taken from within an RDP session via the Ctrl+Alt+Plus (PrtScn equivalent) and Ctrl+Alt+Minus (Alt+PrtScn equivalent) key combos.
      Here is the example code:
      #include <ClipBoard.au3> #include <GDIPlus.au3> If _ClipBoard_IsFormatAvailable($CF_BITMAP) Then ConsoleWrite("+Bitmap found on Clipboard" & @CRLF) If Not _ClipBoard_Open(0) Then MsgBox(16, "Error", "_ClipBoard_Open failed") Exit EndIf $hClipboardImage = _ClipBoard_GetDataEx($CF_BITMAP) _ClipBoard_Close() _GDIPlus_Startup() $hBitmap = _GDIPlus_BitmapCreateFromHBITMAP($hClipboardImage) $sCLSID = _GDIPlus_EncodersGetCLSID("JPG") _GDIPlus_ImageSaveToFileEx($hBitmap, @ScriptDir & "\" & TimerInit() & "_Clipboard_Image.jpg", $sCLSID, 0) _GDIPlus_BitmapDispose($hBitmap) _GDIPlus_Shutdown() Else MsgBox(48, @ScriptName, "No Bitmap found on Clipboard") EndIf If you copy a local window to the clipboard via Alt+PrtScn the above works fine.  If you copy a window in an RDP session via Ctrl+Alt+Minus it saves the image, but the left-hand edge appears to contain a few pixels sliced off the right-hand side of the bitmap (see two attached images for examples; one good, one bad).  If you paste directly into MSPaint, the image appears correctly, so the clipboard contents is good. It seems to be the process of converting the bitmap handle to an image file via GDIPlus which corrupts it (though I may be wrong about this).
      I've tried inspecting the contents of the clipboard via the _ClipBoard_EnumFormats example and I've noticed the clipboard from the RDP session contains a couple more formats;
      Local:
      Clipboard formats ..: 3 Clipboard format 1 .: Bitmap Clipboard format 2 .: DIB Clipboard format 3 .: DIB V5 RDP:
      Clipboard formats ..: 5 Clipboard format 1 .: DataObject Clipboard format 2 .: DIB Clipboard format 3 .: DIB V5 Clipboard format 4 .: Ole Private Data Clipboard format 5 .: Bitmap However the _ClipBoard_GetDataEx function is specifying the $CF_BITMAP constant for the format, which both instances contain, so I'm not sure the extra formats have any impact?
      I've tried using a combination of _ClipBoard_GetDataEx($CF_DIB) and _GDIPlus_BitmapCreateFromMemory in an effort to write the binary directly to a file, instead of using a bitmap handle, however this doesn't appear to work and just returns a zero and doesn't set @error to anything, which isn't covered in the help file (a failure should return a zero and set the @error level to something).
      I've hunted around the forums and tried everything I can think of. I can normally figure most things out without posting but I've been dipping in and out of this script for a few months now and have finally thrown in the towel and must ask you guys for help, which isn't a decision I take lightly.  Your help is, as always, greatly appreciated.
