.net - Graphics.Drawstring Looks Nice In PictureBox But Horrible In A Bitmap?
Aug 5, 2010
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.
Sample code:Use a Windows Forms project and place 2 picture boxes on it and a button and run it with the following code to see what I mean:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

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 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'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.

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

Pretty self-explanatory question. I'm trying to see if I can do sprite animation in Visual Basic and, while I can use a Graphics object to translate a bitmap down a few pixels, I have absolutely no idea how to erase the bitmap drawn in its former position. Is there any way to erase the old image before the new image is drawn onto the form?

faster way to flood fill an area of a bitmap? It basically acts just like the fill flood bucket in MS Paint. clsBitmapImage is a Bitmap variable.
Code:
Code:
Public Sub FloodFill(ByVal AtPoint As Point, ByVal newColor As Color)
Dim oldColor As Color = clsBitmapImage.GetPixel(AtPoint.X, AtPoint.Y)
If oldColor.ToArgb <> newColor.ToArgb Then

I am working on watermarking image.
In the below code I load the image to the graphics path using resource image and adding text on it. When I add the image through open file dialog it paints on the form with original size but I need to resize it, add it to the PictureBox, add text to it and give zoom and pan options to it and then I need to save with the original size.
When I resize and when save the image I endi up with a small image.
Here is my code:
Imports System.Collections.ObjectModel
Imports System.Drawing.Drawing2D
Public Class Form1

The error that I get is "Object reference not set to an instance of an object."[code]...
And is it even possible to do a vb6 style implementation? As I see it, this will clone the picture image while the vb6 implementation will just read directly off the image? and is lockbits like getdibits? I need to process 60 bitmap images of about 200pix by 200pix every second.

As a side project, I'm trying to see how much of Microsoft's Paint Application I can recreate. So far I have it where I can "paste" the image into the application. What I am stuck on however is allowed the image to be edited - being able to edit the individual pixels. How can I "edit" the pixels inside this picturebox? - Jordan If you find an answer , click the button. If you find an answer to your question, mark it as the answer.
