Draw Border Around New Bitmap?

Apr 11, 2010

I need to draw a border of a certain width around a new bitmap.

I want to use Graphics.DrawLines, because i may want to draw the Horizontal or Vertical borders only.

For Example:

Code:
'Add this to a button on a blank form
Dim Canvas As New Bitmap(100, 100)
Dim G As Graphics = Graphics.FromImage(Canvas)

[Code]....

Ive fiddled around with this, but i cant get the math right. What must i do to get the border of the correct width around my bitmap?

Also do i need the first "G.Dispose()"?

Program Run Out Of Memory - Draw Segment Of The Spline To The Bitmap

May 31, 2009

I am building an app that builds a bunch of cardinal splines by storing their PointF structures in arrays. As the program runs, new points are added to the arrays, and the graphics are drawn to a bitmap. I can let it run for ages and the splines just keep growing like they should with no problems. The amount of points in each spline can grow into the thousands. To speed up execution as time progresses, I don't completely redraw the splines after each pass, I simply draw the last segment of the spline to the bitmap, having let the bitmap 'record' the earlier part of the splines.

But if I pan across the scene or zoom in/out of it, then I DO have to completely redraw the splines, since the size and resolution of the display is limited to its dimensions. Panning works, no problem. But if I zoom in and out of the bitmap with the mouse wheel, after about 14 wheel clicks, I get an "Out of Memory" error. BUT...I have it set up so that whenever the mouse wheel turns, the graphics and the bitmap are disposed so that new ones can be built for the new zoom setting. So why would the program run out of memory when as far as I can tell, I am disposing of all my unused, unmanaged resources on a regular basis?

But my question is, I want to fill it the image with that string.Say, the text be "abc".So, the output would look like this for 200x200 bitmap (assumption):

Add Text BELOW Bitmap In Program?

Mar 29, 2011

I'm trying to resize a .NET bitmap without actually scaling the image. The idea here is to create a space above and below the image, fill it with a black rectangle, and place some text there (without covering up or destroying any part of the original image).

All the code and examples I've seen of this thus far just show how to scale the image, not expand the canvas. So far, everything I've tried on my own also scales/stretches the image.[code]....

I want to add some text to a photo (held in a bitmap) but rather than write over the photo itself I want to add a small black bar to the bottom of the image and write some white text in it.

e.g. a 640 x 480 photo becomes 640 x 510 with the black bar at the bottom.

How To Create A Bitmap Image Using A Text File

Jan 9, 2010

I am trying to convert from a text file to an image(bitmap) file.
For example, test.txt: 01 23 34 56 78 90

[Code]....

The first step will be reading the data, so I created some VB codes:

Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.Filter = "Text Files (*.txt)|*.txt"
openFileDialog1.Title = "Select a text File"
' Show the Dialog.

' If the user clicked OK in the dialog and ' an image file was selected, open it.

If openFileDialog1.ShowDialog() = DialogResult.OK Then
' Open file.
[Code]...

The second step will be converting the data to some data format which can be used in a bitmap image. This part is making me confused. Some codes I made is listed below:

Here is a short program to demonstrate my question. I just want to extraxct a rectangle bitmap from a big bitmap.Code as follows:

Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:

"MissingMemeberException was unhandled.

No default member was found for type 'bitmap"

I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

Draw Text On Custom Control?

I have made a custom control and the only change to the interface is that its a different color. Whenever the user moves their mouse over the control some white text fades in in the middle of the user control. Then after a few seconds the text fades out. The text is actually the location of the cursor but I have that figured out.

How To Draw Readable Tiny Text Quickly

Jul 28, 2010

In developing a flash-based memory manager, I need to be able to view large quantities of data. With my eyes and monitor resolution, I can read hand-drawn 3x5 letters on a 4x6 matrix without too much difficulty, but none of the system TrueType fonts render optimally at that size. I've tried writing code to draw font shapes to off-screen bitmaps, and then use DrawImage to copy those bitmaps to the screen, but I can't get good performance. This is for development, not production, so performance doesn't have to be absolutely optimal, but I don't want to spend too long waiting for screens of data to refresh.

What would be the best way of either making .net display a font which is pixel-perfect what I want, or else building a bitmap out of lots of little pieces quickly? I'm using vb.net, so I can't simply generate a bitmap as a byte array and pass that to the Bitmap constructor unless someone can show me how to convert an array into an IntPtr.
