Is there any other object other than "Form" that uses the Alpha Blend?
Or the alpha code for a different object?

For example;
Code:
UDF1.CEPanel1.AlphaBlend=true
UDF1.CEPanel1.AlphaBlendValue=155


If there is a solution, thanks in advance.

EDIT :

I found a code generated by @ mgr.inz.Player and @Dark Byte.
Is it possible to use this code in panel instead of picture?

Code:
function TBlendFunction(SourceConstantAlpha)
  return byteTableToDword({0,0,SourceConstantAlpha,1})
end

function getCanvasHandle(canvas)
  canvas.getPixel(0,0)
  return readPointerLocal(userDataToInteger(canvas)+0xc8)
end

function demo(alpha)
  pngImage = createImage(nil)
  pngImage.Picture.PNG.loadFromStream(findTableFile('example.png').Stream)

  tmpImage = createImage(nil)

  local width  = pngImage.Picture.Bitmap.Width
  local height = pngImage.Picture.Bitmap.Height

  tmpImage.Picture.Bitmap.PixelFormat = pf32bit
  tmpImage.Picture.Bitmap.Width  = width
  tmpImage.Picture.Bitmap.Height = height

  executeCodeLocalEx("msimg32.AlphaBlend", getCanvasHandle(tmpImage.Picture.Bitmap.Canvas), 0, 0, width, height,
                                           getCanvasHandle(pngImage.Picture.Bitmap.Canvas), 0, 0, width, height, TBlendFunction(alpha))

  UDF1.CEImage1.Picture.assign(tmpImage.Picture)
  UDF1.CEImage1.repaint()

  pngImage.destroy()
  tmpImage.destroy()

  UDF1.Caption = 'alpha is '..alpha
end

function UDF1_CETrackBar1Change(sender)
  demo(sender.Position)
end

demo(128)

Please take a conclusion from this statement:

"The AlphaBlend function displays bitmaps that have transparent or semitransparent pixels."

I focused only on making a panel or canvas translucent.
Seeing a panel or canvas instead of a picture in the code above seems to solve the issue. Smile

Yes, I understand the purpose of "AlphaBlend", so I focused on transparency.
