Resizing ToolStrip item's image

问题

Is there any way I can fit/resize the image of ToolStrip item? I already set the property AutoSize = False , ImageScaling = SizeToFit & Size = 40, 40 but only the item's boxes resizing (leave spaces around image) and the image size is still with it's default size.

I then came up with inserting the image using BackgroundImage instead of inserting it at Image. I can fit/resize the image but the problem is when I run my system and pointing the cursor on the ToolStrip item, the item's image disappear. I found this solution Resizing ToolStripButtons to fit complete BackGround image but I don't know how to apply it using vb.net

Kindly to help me. Thank you.

If you want your images show in original size

Set AutoSize property of ToolStrip to true
Set ImageScaling property of ToolStripItem to None

If you want your images show in a specific size

Set AutoSize property of ToolStrip to true
Set ImageScalingSize property of ToolStrip to your specific size, for example 32,32
Set ImageScaling property of ToolStripItem to SizeToFit
