I'm having some problem. I try to create a 16bpp grayscale bitmap image and show in a picture box.
I used the following code
bmp = New Bitmap(xpixels, ypixels, Imaging.PixelFormat.Format16bppGrayScale)
dim bmp = New Bitmap(xpixels, ypixels, Imaging.PixelFormat.Format16bppGrayScale)
PictureBox1.Image = bmp
I'm using Bitmap to show picture box like slideshow using Timer. For each timer interval, I've to go for new instance of Bitmap, there System memory increases to 1MB, How to resolve this, 'BG is picture box
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tic Dim img As Bitmap
img = New Bitmap(System.Drawing.Bitmap.FromFile(FileIO.FileSystem.GetFiles
[CODE]...
I need to convert a Drawing.Bitmap to 4 bit grayscale. Is there any way to accomplish this? I've tried using Bitmap.Clone but I only get the usual infamous "Out of memory" exception. Would this be grayscale even if it managed to convert to 4 bit?

how to rotate,resize,crop any image and save it using vb.net ?
View 2 RepliesJust playing around with VB and have made a program for playing "pairs". The program displays lots of face down cards, then the user can click on them to reveal their face and try to find pairs. This is done by hiding or showing the "card reverse" picture
If the user finds a pair, the cards should stay face up, however if they do not match, they should be returned to facing down.
The pictures need to be loaded dynamically through an array...
The code I have so far is as follows...
Form1...
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

View 3 RepliesI'm trying to make a game, pretty much a game like memory where you flip over a card and find the match. But because of how many buttons I need I was wondering if it was possible to show the picture in a message, all the pictures are funny motivational posters from photobucket so I want the player to be able to read the dialog. I've already tried doing
Dim picture as string = "1.jpg"
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MessageBox.Show(picture)
End Sub
but when I click the button nothing happens and yes the name of the picture in my bin folder is "1". I am using Microsoft Visual Basic 2008 Express Edition.
I need to extract 8 bit grayscale image.
My plan is this:
1. input the picture to a picture box no 1
2. load into memory
3. extract all value to a 2D array matriks
4. process the picture
5. Show the result in picture box no 2
6. End
I met a serious problem when i want to load it to memory. For a faster process i use Graphics class (i've got this trick from my friend). but later I found out that graphics wont work for PixelFormat.Format8bppIndexed.
Here's the code:
Imports System.Drawing.Imaging
Imports System.Runtime.InteropServices.Marshal
Public Class LockImage

View 1 RepliesHow do you make the image in a picturebox vanish when you change an option? I have tried a few different ways that i have seen but none have worked. I have it set so when i change an option in a listbox it will change the picture and data in other controls, however one option in the listbox has no data to fill in those controls and so gets left blank. However when i click on that option right now the images that were in the picturebox before get left behind until i click on another option that has a picture. So how do i remove the picture from the box?

I'm working on a program that allows a person to click on some text and it will read the text (play a wav file) using My.Computer.Audio.Play. The program calls a procedure called PlayAudioClip which uses AudioPlayMode.WaitToComplete because in some cases two wav files will be played one after the other(two languages). During the playing of the wav files I want to show a visible indicator that there is audio. I've got a picturebox called "AudioPic" who's image property points to a picture in my.resources. THe visible property of AudioPic is set to false when the form loads When the user clicks on the text my program should display the image (Visible=true), play the clip (or two) and then hide it again.
It seems that the picture is not completely loaded before the wav file plays and since I have it set to WaitToComplete it stops the loading until the wav file has played, at which time the program hides it.
How can I force it to finish showing the picture before playing the clip?[code]...

I have a form with a web browser on it.
The web browser has a captcha on it.
I want the captcha to be shown on the form iteself.
Maybe in a picturebox or something. But it needs to be the current picture on the web browser.
I have looked around and I couldn't find anything that could achieve this.

Or if this is possible, could I add the image "captchaSF_Image" to the clipboard and then paste it in the picturebox1.image? If so how could this be done?
