Converting image to a defined pallet of colors

Recommended Posts

corgano

What I am trying to accomplish is to simplify a .PNG image and convert it to use only a specified pallet of colors. Eg if I have a pallet of 0xFF0000, 0x00FF00, 0x0000FF, it would change every pixel in the image to one of those three colors by whichever color is closest.

 

The simplest method I have tried is simply converting the image to a 16 bit bitmap, and that does simplify the pallet of the image, but I want to be able to specify what colors it specifies to. The other problem is the resulting saved .BMP file is much larger (file size) than the original, and I don't know if it's possible to make a 16 bit jpg.

 

It looks like _GDIPlus_BitmapConvertFormat is the solution but the help file doesn't go into how to use the pallet and I couldn't find an example that did what I needed. Can anyone help me?

Something like this here?

#include <GDIPlus.au3>

#include <WindowsConstants.au3>


Global $sFile = FileOpenDialog("Selecet an image", "", "Images (*.jpg;*.png;*.bmp)")
If @error Then Exit MsgBox(16, "Error", "You must select an image!", 30)

_GDIPlus_Startup()

$hImage = _GDIPlus_ImageLoadFromFile($sFile)
$iW = _GDIPlus_ImageGetWidth($hImage)
$iH = _GDIPlus_ImageGetHeight($hImage)
$hGUI = GUICreate("GDI+ v1.1 needed", $iW * 2 + 30, $iH + 20)
GUISetState()

$hDC = _WinAPI_GetDC($hGUI)

$hGraphics1 = _GDIPlus_GraphicsCreateFromHWND($hGUI)
_GDIPlus_GraphicsDrawImageRect($hGraphics1, $hImage, 10, 10, $iW, $iH)
_GDIPlus_GraphicsDispose($hGraphics1)

$hGraphics2 = _GDIPlus_GraphicsCreateFromHDC($hDC)

_GDIPlus_GraphicsDrawImageRect($hGraphics2, $hImage, $iW + 20, 10, $iW, $iH)

I knew it would be UEZ to respond. You really are our local GDI expert.

That is really cool and i think we're on the right track, but I'm not looking to use various dots to make up the color, I want to make each area the solid color it's closest to in the pallet. For instance a4Dnd88.png turns into  CoGRTDb.png but the result I'm looking for is  COOWRLe.png

@corgano you have to be more precise what you want.

If you disable dithering in the code from post #2 you will get very similar results:

#include <GDIPlus.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>


Global $sFile = FileOpenDialog("Selecet an image", "", "Images (*.jpg;*.png;*.bmp)")
If @error Then Exit MsgBox(16, "Error", "You must select an image!", 30)

_GDIPlus_Startup()

Global $hImage = _GDIPlus_ImageLoadFromFile($sFile)
Global $iW = _GDIPlus_ImageGetWidth($hImage)
Global $iH = _GDIPlus_ImageGetHeight($hImage)
Global $hGUI = GUICreate("GDI+ v1.1 needed", $iW * 2 + 30, $iH + 20)
GUISetState()


Global $hGraphics1 = _GDIPlus_GraphicsCreateFromHWND($hGUI)
_GDIPlus_GraphicsDrawImageRect($hGraphics1, $hImage, 10, 10, $iW, $iH)
_GDIPlus_GraphicsDispose($hGraphics1)

$tPalette.ARGB((2)) = 0xFF00FF00
$tPalette.ARGB((3)) = 0xFFFF0000
$tPalette.ARGB((4)) = 0xFF000000

_GDIPlus_BitmapConvertFormat($hImage, $GDIP_PXF04INDEXED, $GDIP_DitherTypeSolid, $GDIP_PaletteTypeOptimal, $tPalette)
DllCall($__g_hGDIPDll, "int", "GdipSetImagePalette", "handle", $hImage, "struct*", $tPalette)

Global $hGraphics2 = _GDIPlus_GraphicsCreateFromHWND($hGUI)

How about  _GDIPlus_ImageAttributesSetRemapTable ?

Global $aRemapTable[5][2]
$aRemapTable[0][0] = 4
$aRemapTable[1][0] = 0xFFD3B4BA
$aRemapTable[1][1] = 0xFFFF0000
$aRemapTable[2][0] = 0xFFB5D7B0
$aRemapTable[2][1] = 0xFF00FF00
$aRemapTable[3][0] = 0xFFACAFDB
$aRemapTable[3][1] = 0xFF0000FF
$aRemapTable[4][0] = 0xFF646464
$aRemapTable[4][1] = 0xFF000000

 

Or simply fill the area

#include <GDIPlus.au3>

_GDIPlus_Startup ()

$hImage = _GDIPlus_ImageLoadFromFile("a4Dnd88.png")
$hBmp = _GDIPlus_BitmapCreateHBITMAPFromBitmap($hImage)
_GDIPlus_ImageDispose($hImage)

$hCDC = _WinAPI_CreateCompatibleDC(0)
$hOldBmp = _WinAPI_SelectObject($hCDC, $hBmp)

$hBrush = _WinAPI_GetStockObject($DC_BRUSH)
$hOldBrush = _WinAPI_SelectObject($hCDC, $hBrush)

_WinAPI_SetDCBrushColor($hCDC, 0xFF0000)
_WinAPI_ExtFloodFill($hCDC, 0, 0, _WinAPI_GetPixel($hCDC, 0, 0), 1)
_WinAPI_SetDCBrushColor($hCDC, 0x00FF00)
_WinAPI_ExtFloodFill($hCDC, 100, 0, _WinAPI_GetPixel($hCDC, 100, 0), 1)
_WinAPI_SetDCBrushColor($hCDC, 0x0000FF)
_WinAPI_ExtFloodFill($hCDC, 0, 100, _WinAPI_GetPixel($hCDC, 0, 100), 1)
_WinAPI_SetDCBrushColor($hCDC, 0x000000)
_WinAPI_ExtFloodFill($hCDC, 100, 100, _WinAPI_GetPixel($hCDC, 100, 100), 1)

$hImage = _GDIPlus_BitmapCreateFromHBITMAP($hBmp)
_GDIPlus_ImageSaveToFile($hImage, "result.png")
_GDIPlus_ImageDispose($hImage)

_WinAPI_SelectObject($hCDC, $hOldBrush)
_WinAPI_DeleteObject($hBrush)
_WinAPI_SelectObject($hCDC, $hOldBmp)
_WinAPI_DeleteObject($hBmp)
_WinAPI_DeleteDC($hCDC)

@InnI the magic key word is here color quantization. Probably corgano's example is just a simple one for demonstration purposes.

      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.

      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.

      Hi Community,

      I'm looking for a way to do a Video Overlay GUI or something like that. The idea is to create a GUI which plays a video loop (with transparency/alpha channel) in front of an other GUI. Before you asking why - because I don't believe that GDIPlus can do it out of the box. My skillset for that kind of graphical things isn't good enough to do that, but here are some specialist like @UEZ maybe who can help.

      Example alpha channel video (visualized as animated *.gif):

      I tried to do the light rays effect directly with GDIPlus, but honestly that's a bit too difficult for me. I would be very glad and grateful if there are some suggestions, ideas or recommendations.

      Code for the Video play:
       
      Example video "End.mpeg":
       
      The next challenge is that the overlay GUI should be not clickable. If I hover over the overlay area, I want to have the possibility to control the GUI or what ever, in the background. But if there is any chance to make it with GDIPlus as a Video Overlay for light rays, I would prefer that approach instead of my crazy work-around idea.

      Thanks for any suggestion - I'm grateful!

      I had thought that _GDIPlus_ImageClone($hImage) removes all property items, but I now know that it copies property items.
      What is the easiest way of copying an image that has property items to another image that does not have property items?
    • c.haslam
      By c.haslam
      I think that _GDIPlus_ImageGetPropertyItem should return a Property Item that can readily be set as a property of another image. Why would one want to do this? A script might (as one of mine does) edit an image of a .jpg file then write the result to a .jpg file. In editing it, in my case, the number of horizontal and vertical pixels change, and the date/time edited should be set as a property. All other property items remain the same. Other GDI+ users may change other properties.
      So an approach is to copy all the property items from image1 to image2, then update a few properties.
      M$ 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 ? "HKLM\SOFTWARE\Wow6432Node\AutoIt v3\AutoIt" : "HKLM\SOFTWARE\AutoIt v3\AutoIt"), "InstallDir") & "\Examples\GUI\Torus.png") If @error Then _GDIPlus_Shutdown() MsgBox(16, "", "An error has occured - unable to load image!", 30) Return False EndIf Local $ar = _GDIPlus_ImageGetPropertyIdList($hImage) Local $vPropNbrs[UBound($ar,1)-1] ; Extract ID numbers For $i = 1 To UBound($ar,1)-1 $vPropNbrs[$i-1] = $ar[$i][0] Next ; Get all property items Local $aPropItems[UBound($vPropNbrs)][4],$vPropItem For $i = 0 To UBound($vPropNbrs)-1 $vPropItem = cGDIPlus_ImageGetPropertyItem($hImage,$vPropNbrs[$i]) For $j = 0 To 3 $aPropItems[$i][$j] = $vPropItem[$j] Next Next ; Collapse values arrays so _ArrayDisplay can display them Local $ar = $aPropItems For $i = 0 To UBound($aPropItems,1)-1 $ar[$i][0] = '0x'&Hex($ar[$i][0],4) $ar[$i][3] = '' For $j = 0 To UBound($aPropItems[$i][3])-1 $ar[$i][3] &= ($aPropItems[$i][3])[$j]&'|' Next $ar[$i][3] = StringTrimRight($ar[$i][3],1) Next _ArrayDisplay($ar) _GDIPlus_Shutdown() EndFunc Unfortunately this example (based on one now in the Help) does not exercise most of the item types, but I do not know of a file with EXIF metadata that is on most PCs. 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?
