_GDIPlus_BitmapCreateBitmapWithAlpha()

Recommended Posts

Yashied

This small function allows you to add an alpha channel (mask) to the specified GDI+ bitmap (see screenshots). Source bitmap and mask may be of any color depth. The output bitmap is always 32 bits-per-pixel with alpha channel. Optionally, the alpha channel may be generated from any channel of the specified mask (1 - Red, 2 - Green, 3 - Blue, or 0 - Alpha). The example below is written for Autoit 3.3.12.0.

I too would like to "study" the ASM code.

I didn't write ASM code, I wrote and compiled DLL in other language and then retrieved a binary code of appropriate function. In AutoIt this function looks like this, but in AutoIt it takes a lot of time.

Func _AddAlpha($pBits1, $pBits2, $iWidth, $iHeght, $iChannel)
    If (Not $pBits1) Or (Not $pBits2) Or ($iChannel < 0) Or ($iChannel > 3) Then Return 0
    Local $iOffset = 3 - $iChannel
    For $i = 0 To $iWidth * $iHeght * 4 - 4 Step 4
        Local $tData1 = DllStructCreate('byte', $pBits1 + $i + 3)
        Local $tData2 = DllStructCreate('byte', $pBits2 + $i + $iOffset)
        DllStructSetData($tData1, 1, DllStructGetData($tData1, 1) * DllStructGetData($tData2, 1) / 255)
    Next
    Return 1
EndFunc

Retrieving binary code:

#Include <WinAPIEx.au3>

$File = FileOpenDialog('Select File', @ScriptDir, 'Libraries (*.dll)|All Files (*.*)', 1 + 2)
If Not $File Then
    Exit
EndIf
$hModule = _WinAPI_LoadLibrary($File)
If Not $hModule Then
    MsgBox(0x00040010, 'Error', 'Unable to load ' & StringRegExpReplace($File, '^.*\\', '') & '.')
    Exit
EndIf
Do
    $pFirst = _WinAPI_GetProcAddress($hModule, 'First')
    If @Error Then
        MsgBox(0x00040010, 'Error', '"First()" procedure not found.')
        ExitLoop
    EndIf
    $pLast = _WinAPI_GetProcAddress($hModule, 'Last')
    If @Error Then
        MsgBox(0x00040010, 'Error', '"Last()" procedure not found.')
        ExitLoop
    EndIf
    $tData = DllStructCreate('byte[' & Number($pLast - $pFirst) & ']', $pFirst)
    If @Error Then
        MsgBox(0x00040010, 'Error', 'Invalid addresses.')
        ExitLoop
    EndIf
    $Code = String(DllStructGetData($tData, 1))
    ConsoleWrite($Code & @CR)
    ClipPut($Code)
Until 1
_WinAPI_FreeLibrary($hModule)

Here Alpha.dll (x86) for example.

I've decided to experiment and wrote a version of this function by using threads (up to 4). Yes, it reduced the time to perform external function, but unfortunately most of the time consuming _GDIPlus... function. Nevertheless, if anyone is interested here is a function.

 

#Include <GDIPlus.au3>

If StringRegExpReplace(@AutoItVersion, '(?<!\d)(\d)(?!\d)', '0\1') < '03.03.12.00' Then
    MsgBox(16, 'Error', 'Require AutoIt 3.3.12.0 or later.')
EndIf

_GDIPlus_Startup()
$hBitmap = _GDIPlus_BitmapCreateFromFile(@ScriptDir & '\Image.png')
$hAlpha = _GDIPlus_BitmapCreateFromFile(@ScriptDir & '\Alpha.png')
$hResult = _GDIPlus_BitmapCreateBitmapWithAlpha($hBitmap, $hAlpha, 1)
_GDIPlus_ImageSaveToFile($hResult, @ScriptDir & '\Image+Alpha.png')
_GDIPlus_BitmapDispose($hResult)
_GDIPlus_BitmapDispose($hBitmap)
_GDIPlus_BitmapDispose($hAlpha)
_GDIPlus_Shutdown()

Func _GDIPlus_BitmapCreateBitmapWithAlpha($hBitmap, $hAlpha, $iChannel = 0)

      I had thought that _GDIPlus_ImageClone($hImage) removes all property items, but I now know that it copies property items.
      What is the easiest way of copying an image that has property items to another image that does not have property items?

      I think that _GDIPlus_ImageGetPropertyItem should return a Property Item that can readily be set as a property of another image. Why would one want to do this? A script might (as one of mine does) edit an image of a .jpg file then write the result to a .jpg file. In editing it, in my case, the number of horizontal and vertical pixels change, and the date/time edited should be set as a property. All other property items remain the same. Other GDI+ users may change other properties.
      So an approach is to copy all the property items from image1 to image2, then update a few properties.
      M$ provides a Property Item class (id, length, pointer to an array of values) but _GDIPlus_ImageGetPropertyItem returns something different.
      I think that, wherever reasonable, UDFs that are wrappers for M$ methods should work like M$'s methods. _GDIPlus_ImageGetPropertyItem does not do this:
      While M$ returns 2 values for a value that is a ratio of 2 numbers,  _GDIPlus_ImageGetPropertyItem returns numerator/denominator as a single value (often a Double). _GDIPlus_ImageSetPropertyItem (when included in GDIPlus.au3) will be unable to set ratio property items properly because it cannot know what the numerator and denominator are. So copying such property items will not work properly. M$ has a Void* buffer where the buffer is an array of values but _GDIPlus_ImageGetPropertyItem() returns the values in the same 1-d array as id, length and type. M$'s approach produces a 1-d array with the same number of elements for all property items while _GDIPlus_ImageGetPropertyItem produces a 1-d array with various numbers of elements. To me, this is not good programming practice. For a photo from a Sony camera, the worst case has 1-d array with 67 elements. When combined into a 2-d array with the property items of all properties, there are 66 rows and 67 columns, with many elements not used. So I suggest that _GDIPlus_ImageGetPropertyItem look like this:
      ; #FUNCTION# ==================================================================================================================== ; Name ..........: cGDIPlus_ImageGetPropertyItem ; Description ...: Gets a specified property item (piece of meta data) from an Image object ; Syntax ........: cGDIPlus_ImageGetPropertyItem($hImage, $iPropID) ; Parameters ....: $hImage - Pointer to an image object ; $iPropID - Identifier of the property item to be retrieved ; Return values .: Success: Array containing the values of the property item ; [0] - identifier ; [1] - size, in bytes, of the value array ; [2] - type of value(s) in the value array ; [3] - value array ; Failure: Sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPID_ERR*). ; Author ........: Eukalyptus ; Modified ......: c.haslam ; Remarks .......: types: unsigned byte = 1, ASCII string = 2, unsigned short = 3, unsigned long = 4, ; unsinged rational = 5, undefined = 7, signed long = 9, signed rational = 10 ; Related .......: _GDIPlus_ImageGetPropertyIdList ; Link ..........: https://msdn.microsoft.com/en-us/library/windows/desktop/ms535390(v=vs.85).aspx, ; https://msdn.microsoft.com/en-us/library/windows/desktop/ms534493(v=vs.85).aspx, ; https://msdn.microsoft.com/en-us/library/windows/desktop/ms534414(v=vs.85).aspx ; Example .......: Yes ; =============================================================================================================================== Func cGDIPlus_ImageGetPropertyItem($hImage, $iPropID) Local $iSize = __GDIPlus_ImageGetPropertyItemSize($hImage, $iPropID) If @error Then Return SetError(@error, @extended, -1) Local $tBuffer = DllStructCreate("byte[" & $iSize & "];") Local $pBuffer = DllStructGetPtr($tBuffer) Local $aResult = DllCall($__g_hGDIPDll, "int", "GdipGetPropertyItem", "handle", $hImage, "uint", _ $iPropID, "uint", $iSize, "struct*", $tBuffer) If @error Then Return SetError(@error, @extended, -1) If $aResult[0] Then Return SetError(10, $aResult[0], False) Local $tPropertyItem = DllStructCreate("int id; int length; short type; ptr pvalue;", $pBuffer) Local $iBytes = DllStructGetData($tPropertyItem, "length") Local $pValue = DllStructGetData($tPropertyItem, "pvalue") Local $aRet[4] Local $type = DllStructGetData($tPropertyItem,'type') Local $tValues, $iValues Switch $type Case 2 ;ASCII String $iValues = 1 $tValues = DllStructCreate("char[" & $iBytes & "];", $pValue) Case 3 ;Array of UShort $iValues = Int($iBytes / 2) $tValues = DllStructCreate("ushort[" & $iValues & "];", $pValue) Case 4, 5 ;Array of UInt / Fraction $iValues = Int($iBytes / 4) $tValues = DllStructCreate("uint[" & $iValues & "];", $pValue) Case 9, 10 ;Array of Int / Fraction $iValues = Int($iBytes / 4) $tValues = DllStructCreate("int[" & $iValues & "];", $pValue) Case Else ;Array of Bytes $iValues = 1 $tValues = DllStructCreate("byte[" & $iBytes & "];", $pValue) EndSwitch $aRet[0] = DllStructGetData($tPropertyItem,'id') $aRet[1] = $iBytes $aRet[2] = $type Local $aVals[$iValues] If $type=2 Or $type=7 Then ; ASCII string or undefined $aVals[0] = DllStructGetData($tValues,1) Else For $i = 0 To $iValues-1 $aVals[$i] = DllStructGetData($tValues,1,$i+1) Next EndIf $aRet[3] = $aVals Return $aRet EndFunc And here is an example:
      #include <GDIPlus.au3> #include <Array.au3> Example() Func Example() _GDIPlus_Startup() Local $hImage = _GDIPlus_ImageLoadFromFile(RegRead((@AutoItX64 = True ?

I have tested this code by updating and adding property items to torus.jpg and to a photo taken by a Sony camera. The code for implementing and calling _GDIPlus_ImageSetPropertyItem will be fairly simple [see below].
       
      Your thoughts?

      I have a strange symptom of a problem somewhere in my code, or in a UDF: when I add code to get all properties of a GDI+ image to a 6000-line script,  the variable type of a parameter is reported as a pointer when the caller clearly has this argument as a string. If I comment out my code that gets the properties, the function properly sees the parameter as a string.
      [Edit: The reporting as a pointer and getting image properties are miles apart, both in where they are in the script code and in where they are run.]
      At this point, I am looking for clues as to why this is happening, so the hunt is on!
      I have noticed one odd thing, in _GDIPlus_ImageGetPropertyIdList() I see a line that begins Local $sPropertyTagInfo = . This "line" is split into 2 lines. SCiTE shows that the first line is 2454 characters and the second 2400. Adding these numbers I get 4854 characters.
      But the Help for AutoIt3 Limits/defaults says that MAXLINESIZE, Maximum size for a line of script, is 4096 characters.
      The line would exceed the limit if AutoIt considers the subject line to be 1 line and not 2 lines.
      My question: is this line legal? Is buffer overun possible?
