Re: Get File Info

You have two sets of sizes for a picture --- the physical size of the image (if you were to print it and not grow/shrink/stretch the image) and the pixel size.

vb.net Syntax (Toggle Plain Text)
	Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
		Dim fName As String = "C:\picture.bmp"
		Dim img As Image = Image.FromFile(fName)
		Dim pixelHeight As Integer = img.Size.Height
		Dim pixelWidth As Integer = img.Size.Width
		Dim physicalHeight As Decimal = img.Size.Height / img.VerticalResolution
		Dim physicalWidth As Decimal = img.Size.Width / img.HorizontalResolution
		System.Diagnostics.Debugger.Break()
		img.Dispose()
	End Sub
	Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
		Dim fName As String = "C:\picture.bmp"
		Dim img As Image = Image.FromFile(fName)
		Dim pixelHeight As Integer = img.Size.Height
		Dim pixelWidth As Integer = img.Size.Width
		Dim physicalHeight As Decimal = img.Size.Height / img.VerticalResolution
		Dim physicalWidth As Decimal = img.Size.Width / img.HorizontalResolution
		System.Diagnostics.Debugger.Break()
		img.Dispose()
	End Sub
