I am designing a simple picture viewer with ability to do some basic image processing. At the moment I have the problem of keeping the PictureBox
centered inside a TabPage
all the time as well as keeping the picturebox width and size same as the picture its showing. So far I had no success.
I have the following code that I call in form constructor to position it in center. it works the first time to center the picturebox:
private void SetPictureBoxOriginalSizeAndLocation(bool makeImageNull = false, DockStyle dockStyle = DockStyle.None)
{
if (makeImageNull) picBoxView.Image = null;
picBoxView.Dock = dockStyle;
var xPoint = tabImageView.Location.X + ((splitContainer.Panel2.Width / 2) / 2);
var yPoint = tabImageView.Location.Y;
var width = tabImageView.Width / 2;
var height = (tabImageView.Height / 2) - toolStripImageView.Height;
if (picBoxView.Image == null) return;
//Resize image according to width
picBoxView.Image = ImageMethods.ResizeImage(picBoxView.Image.Tag.ToString(), width, height, false);
picBoxView.Location = new Point(xPoint, yPoint);
picBoxView.Width = width;
picBoxView.Height = height;
}
But it does not resize the picturebox to its image (you can see the black part that is back color for the picturebox control):
The problem is getting worse as soon as I resize the form, the picturebox position will goes to top:
I call the code above in form's resize event as well, no idea why it works when application starts. Would be nice if someone can tell me what properties I should take care of to achieve a nicely centered picturebox which always is as big as its image.
