[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.

      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.

      This is a project that I have been working on for several months off and on.
      It's a simple "What You Hear" MP3 @ 320Kbps and WAV audio recorder.
      Features:
      - LoudMax, a Gain Controller and Look-Ahead Limiter
      - Auto Shut-Off after one minute of silence
      - Side-by-Side Simulated LED Meter
      - Running Time Counter
      It started off being a large project, but I eventually stripped it down to its
      bare essentials because I came to realize that it would be very difficult to
      deal with every sound card and every way a PC is set up for audio. It would
      have been a nightmare that I was not willing to go through.
      This project contains the most up-to-date BASS.dll v.2.4.15.0 - December 17, 2019.
      All BASS Dll's are 32bit. Those and the needed UDF's are included in the zip file.
      I will try to explain how it works in the next post.

      I have been working on audio graphical scripts these last several months.
      This is my last script on this subject for now. On to other projects.
      Credits: UEZ, Eukalyptus, BrettF, Prog@ndy, Authenticity and the AutoIt Community.
      Thanks to all that made these scripts possible!
      Please let me know if you have any problems with it.

      I have been playing with this script off and on for about a month - trying to get the needles to look more realistic.
      It's best to use with an audio limiter on the source audio, or else you'll be tweaking the input levels on every song.
      It should work with any version of AutoIt, starting with 3.3.8.1.
      Please report any problems with it. Credits are in the script.
