draw string in a bitmap

hi, i have this code:

    objBmpImage = New Bitmap(objBmpImage, New Size(960, 832))
    objGraphics = Graphics.FromImage(objBmpImage)
    objGraphics.SmoothingMode = SmoothingMode.AntiAlias
    objGraphics.TextRenderingHint = TextRenderingHint.AntiAlias
    objGraphics.DrawString(vtext, New Font("Arial", 35, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Pixel), Brushes.White, 30, 25)


how can i draw this string inside my working area of the bitmap, so if the string is small, then the size will be bigger to fill the space, if the string is bigger then the size  it will be small. and how to justify the text.

Try something like this:
        Dim margin As Integer = 30
        objBmpImage = New Bitmap(objBmpImage, New Size(960, 832))
        Using objGraphics As Graphics = Graphics.FromImage(objBmpImage)
            objGraphics.SmoothingMode = SmoothingMode.AntiAlias
            objGraphics.TextRenderingHint = TextRenderingHint.AntiAlias

            Dim fSize As Integer = 7
            Dim F As Font = Nothing
            Do
                fSize = fSize + 1
                If Not IsNothing(F) Then
                    F.Dispose()
                End If
                F = New Font("Arial", fSize, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Pixel)
            Loop While objGraphics.MeasureString(vtext, F).Width < objBmpImage.Width - (2 * margin)
            objGraphics.DrawString(vtext, F, Brushes.White, margin, 25)
            F.Dispose()
        End Using

Open in new window


It simply increases the size of the font until it no longer fits in the desired space.

hi idle_mind,

i´m sorry but i put the wrong line for the string, the right one is this one:

objGraphics.DrawString(vtext, New Font("Arial", 80, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Pixel), Brushes.White, System.Drawing.RectangleF.FromLTRB(10, 120, 950, 810))

because the one i put before it~s just for one line, and i want to fit not only on the line but the text goes all the way to the end of the image, so i have an rectangleF, i need to scale to fit on this rectangle.

any help

emoreau,

this is not what i want, because i am doing inside an rectangleF, and not just one line so the thext goes inside a box, and i want to scale the font to fit this box, so, if i have long text, the font will be set smaller to fit the area i am printing the text, if the text is short the font will be bigger so it will fit this area.

Is the text supposed to wrap?...or does it have distinct lines that must stay on those lines and you want to maximize how those lines fit in the box?
