So, what I've got is a picturebox and a textbox, I got some code to put text into a picturebox so I could better understand how it works, but what I don't understand is how to put the text on top of the image that is in the picturebox, can anyone tell me how to do that? Here's the code

I'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway,
my sample application seems to draw a text string at an image resolution of

I am using the e.graphics.drawstring to print labels and textboxes. One of the labels is "#". Whenever I print, although it is centered in its label on the screen, the text in the label aligns to the left. Is there a way to get it to center? This is happening with all my textboxes and labels.
e.Graphics.DrawString(lblNumber.Text, lblNumber.Font, Brushes.Black, 9, 55)
I'm making a class to basically print the screen. I'm going through each field and doing a drawstring, but things aren't lining up correctly. I tracked the problem down and don't know why it's happening.Take this line of code as an example:
Me.CreateGraphics.DrawString(Label1.Text, Label1.Font, Brushes.Black, Label1.Left, Label1.Top + 30)
This should draw the same text that is in label1 directly below label1 on the form. However, the drawn text is a different length than the label's text. Courier draws shorter, Sans Serif draws longer. It's doing the same thing going to a print document; it isn't matching how the label is being rendered.
Im working on a project that needs to print a report of one client.Everything went smooth untill i came across my multiline input text data.When i display it in the PrintPagePreview the text go's outside my page. Even when im printing it only the halve of my text is displayed. I googled and looked everywhere but i can't get a clear fix for it.

I have a routine that creates a report which includes text and graphics. When I print to a PDF or printer the output looks great. When I draw the report on an image to save as a PNG, GIF, JPEG, etc. it does not look as good and I understand that is related to the 96 dpi native resolution. However, I made some modifications, and even though the graphics part of the image looks better, the text does not look as good as the PDF. I am creating the image using 300 dpi and text rendering is set at the highest quality.

View 7 RepliesI was unhappy with the kerning in one of the installed fonts on my system, so I re-defined the kerning in a font editor and installed the revised font (under a new name) on my system. When I use the new font in Microsoft Word or Adobe Photoshop, my new kerning works fine - but when I use Drawstring in a VB program, although the new font is used, the kerning instructions are ignored.Does anyone know if this a feature of the Graphics.Drawstring method, or am I failing to set a switch somewhere? If it's a feature, is there another method which kerns correctly?

I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.

I draw text (comment on item in an invoice ) inside a rectangle.
[Code]...
I have no problem, the text appear on several lines and it is well wrapped. But if the text is too long to be drawn inside the rectangle, I need to draw the text not drawn in another rectangle (on another page). How can I know the text not drawn in the first rectangle ? I think it is more difficult to use MeasureString because the text is wrapped.
how would you identify the shape of text like inside a scanned document containing text and graphics?In a perfect world,users would never enter data in the wrong form,files they choose to open would always exist and code would never have bugs.[URL]

I know that you can pass a Point array to the DrawImage method of the Graphics object to apply rotation, skewing and flipping, but I'm having trouble figuring out how to calculate the rotation. So far I've got:
Dim radius As Integer = Math.Sqrt((rect.Width / 2) ^ 2 + (rect.Height / 2) ^ 2)
Dim dX As Integer = RadToDeg(Math.Cos(DegToRad(angle))) * radius
Dim dY As Integer = RadToDeg(Math.Tan(DegToRad(angle))) * dX
Dim new_upper_left_corner As New Point(rect.X + (rect.Width 2) - dX, rect.Y + (rect.Height 2) - dY)
This is all just off the top of my head so far, I'm not sure if it's right. How do I calculate the other points on the rectangle, and is there a built-in VB.NET method that's much easier? (Apart from Graphics.RotateTransform, which is slow and also rotates around 0,0.)
I dipped my toe in the world of user controls as needed to double buffer a panel control and now want to create a picturebox control with a thicker border.

how to use DrawString (or any other method) to draw text that's reversed? For example, instead of having black text over a background image, you draw a black filled rectangle over the image, and then use DrawString to "punch through" the black rectangle exposing the image underneath.
