I was trying with a code that coverts Text to Image using Vb.net and my problem is I need to accept a message from user (Max 160 Characters) by a text box and i need to convert it to a Image. The generated image should be aligned in the middle and the image max resolution should be 800x600.
So the message should be neatly aligned in new lines if needed and perfectly aligned to the middle.
The code I am trying is as follows:
======================================================
Try
Dim Text As String = TextBox3.Text
Dim FontColor As Color = Color.Blue
Dim BackColor As Color = Color.White
Dim FontName As String = "Times New Roman"
Dim FontSize As Integer = 36
Dim Height As Integer = 60
Dim Width As Integer = 200
Dim daten As String
daten = Now.ToString("ddMMyyyyhhmmss")
Dim FileName As String = daten
Dim objBitmap As New Bitmap(Width, Height)
Dim objGraphics As Graphics = Graphics.FromImage(objBitmap)
Dim objColor As Color
objColor = Nothing
Dim objFont As New Font(FontName, FontSize)
'Following PointF object defines where the text will be displayed in the
'specified area of the image
Dim objPoint As New PointF(5.0F, 5.0F)
Dim objBrushForeColor As New SolidBrush(FontColor)
Dim objBrushBackColor As New SolidBrush(BackColor)
objGraphics.FillRectangle(objBrushBackColor, 0, 0, Width, Height)
objGraphics.DrawString(Text, objFont, objBrushForeColor, objPoint)
objBitmap.Save("D:\DNB\" + daten + ".JPG", ImageFormat.Jpeg)
PictureBox1.Image = Image.FromFile("D:\DNB\" + daten + ".JPG")
Catch ex As Exception
End Try
Have you tried the MeasureString function of the Graphics object and it's various overrides? With that you can measure how much space a text in a given size and font needs on the screen. With that knowledge you can calculate the upper left point to use to make the text appear centered.
