How to get the correct Image height and width

Question

I am trying to calculate the size of a Rectangle using the Height and Width of an image in my project. The image (icon) is 20px W and 16px H. When I load it in from a ImageList and look at the image size, it shows that it is 16px X 16px.

I assume that there is some compression that is being applied to the image, but I am not very experienced in this area. I just need to get the correct, dimensions. Is there any way?

NOTE: I am not loading the file from disk... it is in my project.

This, simply, is what I am doing:

var tabPage = _tabControl.TabPages[e.Index];

var image = _tabControlImageList.Images[tabPage.ImageIndex];
var imageHW = Math.Max(image.Height, image.Width);

Answer 1

You can and must declare a ImageSize you want to have, before you load the Images into the ImageList :

_tabControlImageList.ImageSize = new System.Drawing.Size(20, 16);

Afterwards all your Images inside the ImageList will have following size: 20x16px .
