View 3 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)

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 4 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?
VS 2010 Draw Characters Or Strings In A Bitmap (fill It)?
Jul 19, 2011I was wondering how to draw characters/string on a bitmap.For example: I have created a new Bitmap with resolution of 200x200. Now using Graphics.DrawString(), I have to draw text. I can draw text. 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):

WPF Blurry Images - Bitmap Class
Jun 12, 2009I am using the following sample at [URL] within VB.NET. The code is shown below. I am having a problem when my application loads the CPU is pegging 50-70%. I have determined that the problem is with the Bitmap class. The OnLayoutUpdated() method is calling the InvalidateVisual() continuously. This is because some points are not returning as equal but rather, Point(0.0,-0.5). Any better implementation for pixel snapping a Bitmap image so it is not blurry?

View 4 RepliesBitmap Array With Dynamic Contents
Apr 2, 2010I'm working on a program that has to get a set of images and then scan them to find pixels that match colors in an color array. Anyway I think I got everything working but how to load the images in as bitmaps. See the images are dynamic, they change there filenames so I can't call them with a static call like Dim bmp2 As New Bitmap("c:button.gif").
So I am using a loop to feed the images into an array for bitmap but thats not working, anyway that I can do this as, right now the program gets all the filenames for the images from a text file that is sent in to us. All I need to do is have the program check each image for pixels that match our color list. But I cant get the images into the bitmap array.
Bitmap From Clipboard Needs Array Pinned?
Dec 12, 2011If I do the same thing in Paint it works OK. But if I open a .bmp file into Photoshop.Select All and Copy to put it on the clipboard. Then my code then reads the stream into a byte array and eventually makes a Bitmap from it.If I assign the bitmap to a background image it displays OK.But if I insert it into a RichTextBox using Khendys Gordon's method it does not display.However, I find if I clear the Clipboard before inserting it, it does display OK.I suspect the Bitmap is using the Clipboard for backing much like when and Image is created from a disk file.But it is confusing because I copy the stream into a byte array and make the Bitmap from the array. It would seem that once the values are copied into a new array the backing would not be in play any more.

VS 2008 Filling Array With Pixel Data And Turning It Into A Bitmap?
Jul 22, 2009I have a small 10px by 10px image, and I want to use VB.NET to find out if that image is (an exact) part of a larger image.I thought a method of doing this would be to lock the bits of the larger image into memory and then loop through each pixel in the image and for each pixel, I could take the 10px by 10px section which is down and to the right of that pixel.. and then compare it to my smaller image.
This is the code I have so far:
'Lockbits of larger image to memory
Dim bmp As New Bitmap(Image.FromFile(System.AppDomain.CurrentDomain.BaseDirectory() & "picture.bmp"))
Dim pxF As PixelFormat = PixelFormat.Format24bppRgb
[code]....
when I'm looping through the 10 by 10 section and I find the R G B bytes for each pixel, how do I store this in my rawImage array so I can convert it to a back bitmap and compare it with my original small 10by10 image?

Nov 6, 2011I'm trying to make a Blackjack game in VB. What I'd like to do is populate an array with each of the cards so that I can randomly generate integers and use those integers to pull an index from the array, basically randomly selecting a card. My problem is that I can't seem to get the images in the resources folder to go into the array. I'd like to use a For/Next loop to populate the array, as I would rather not manually assign all 52 cards to the array. I'm trying to do it like this:

Dim LoopIndexInteger As Integer
For LoopIndexInteger = 0 To 51
CardArray(LoopIndexInteger) = My.Resources.ResourceManager.GetObject(LoopIndexInteger)
