Question

To see the problems, please follow these steps (I am coding in C#):

1. Put a picturebox on a form named picturebox1
2. Resize it to small rectangle (say 75,75)
3. Add a picture to resources (named say pic) larger than that rectangle (say 500,500)

Now we are ready 😀

I know two ways to have this picture shown in the picturebox at runtime while showing the whole picture not only a part of it:

1. Adding Imagelist and setting size (this is not good at all)
2. Writing onPaint of that picturebox something like this:

e.Graphics.DrawImage(Properties.Resources.pic,
new Rectangle(0,0,75,75));

Lets assume that I want to fill the Image property of the picturebox1, now I must write something like this:

pictureBox1.Image = (Image)Properties.Resources.ResourceManager.GetObject(“pic1”);

which does not resize the image retrieved. I want to know if there is a good way around this problem (to resize and assign easily)? BTW, I don’t want to resize the picture using something like these

1. Image Editing Using C#
2. Image Editing while maintaining aspect ratio

Now the second question:

I know resources are statically added in my example, but is there a way to get the name of the resource programmatically instead of hardcoding it as string and passing it to the “GetObject()” method?

Answer 1

By default PictureBox doesn’t size the image to fit with its display area. Try this:

pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage
