Can't Make A New Bitmap From A Picturebox

Nov 25, 2010

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.

Editing Bitmap In Picturebox

Jun 14, 2011

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.

.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

[Code]...

Convert Bitmap To Icon Using Binary Data?

Feb 21, 2011

I would like to convert an Bitmap image to an icon in VB.NET but I have to use the binary data of each to somehow accomplish that. Doing research on Bitmap I found how the files are structured. I know that bitmaps have the Bitmap Filer header, Bitmap infoheader, and the colorallet. Each of these contain a certain amount of bytes, and I a have to get these from the bitmap file. The icon header and info header are similar to the bitmap. I know that there are libraries in VB.NET that do that easily, butthis is for a project for school and I am not supposed to use that. I just want to ask how

Save Video Data Into Image And Convert Into Bitmap Format

May 25, 2009

I have the following code found on internet:
Const WM_CAP_START = &H400S
Const WM_CAP_EDIT_COPY = WM_CAP_START + 30

'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:

'---save the video data into the Image global variable---
Public Sub CaptureImage()
Dim data As IDataObject
Dim bmap As Image
Dim ms As New IO.MemoryStream()
'---copy the image to the clipboard---
[Code] .....

The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.
