  C1MainMenuItems with an image with the pixel in the bottom left corner set to black will set all black pixels in the image to transparent. Since the transparent color can be set in the C1CommandHolder, there should be no need for this “feature”.
  
  I create all my menu item images on the fly from svg files which allows for easy scaling and color changes. I added the below sub to slightly change the color of the pixel, and it appears to work.
  
  Private Sub kludgeFixPixel(ByRef bm As Bitmap)
  
  Dim pixelColor = bm.GetPixel(0, bm.Height - 1)
  
  Dim redValue = IIf(pixelColor.R = 0, 1, pixelColor.R - 1)
  
  Dim newPixelColor = Color.FromArgb(pixelColor.A, redValue, pixelColor.G, pixelColor.B)
  
  bm.SetPixel(0, bm.Height - 1, newPixelColor)
  
  End Sub

  Hello,

  Thanks for sharing your observations. ImageTransparentColor Property of C1CommandHolder can be set for images not in the image list.
  
  http://help.grapecity.com/componentone/NetHelp/c1command/webframe.html#C1.Win.C1Command.4~C1.Win.C1Command.C1CommandHolder~ImageTransparentColor.html

  Please refer the attached sample and see the items contained in C1MainMenu do have images set such that they have black pixels at the bottom left corner.
  
  Let us know if this is not what you mean, using a stripped down sample or a small video.

  Best Regards,
  
  Esha

  Hi Esha,
  
  the second item under the first menu item is missing the square icon, which is what I was describing. Here is my test project that illustrates the same thing.
  
  The color of the pixel in the bottom left corner of the image becomes the transparent color, not just black. It could be any color (and I think the alpha is ignored)

  Hi

  Kindly be informed, by using a new property “ImageTransparentColor”, icon is shown in main menu in the latest builds.

  You can either update to 2018-V2 builds using C1Live utility or get the builds from here :
