View 2 RepliesDraw Border Around New Bitmap?
Apr 11, 2010I 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()"?

View 10 RepliesProgram Run Out Of Memory - Draw Segment Of The Spline To The Bitmap
May 31, 2009I 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?

Can't Make A New Bitmap From A Picturebox
Nov 25, 2010The 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.
Editing Bitmap In Picturebox
Jun 14, 2011As 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.

.net - Graphics.Drawstring Looks Nice In PictureBox But Horrible In A Bitmap?
Aug 5, 2010I 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
