Interface And Graphics :: Resizing Picture In Picturebox With Good Quality?
May 15, 2009
The problem is that i am trying to resize pictures so they fit into a picturebox with good quality. I have found a code (se attached code) on the internet that resize the picture correctly but the quality is poor.
If i resize the picture in Adobe photoshop before i put it into the picturebox the quality is good so there is nothing wrong with the orginal picture or the picturebox. It's the resizing that is the problem.
Here is the code.
'Generate new image dimensions
Public Function GenerateImageDimensions(ByVal currW As Integer, ByVal currH As Integer, ByVal destW As Integer, ByVal destH As Integer) As Size
[Code]......

I have a form with a TabControl that is set to fill the entire form. On one page I have a SplitContainer that I set the Dock to Fill.When I resize the window the TabControl resizes with it, but not the SplitContainer. I'm assuming I just have some properties set wrong.
Code:
'
'ResultSplitContainer
'
Me.ResultSplitContainer.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D

I've been trying to get some help for this in another thread,but it looks like it's a task that is going to need a wider audience to try and find someone who knows something about writing/creating procedural textures at the pixel level in VB.Net. The VB6 example I'm trying to convert to VB.Net is attached to this post.

It seems difficult to find good information on working with bitmaps. Specifically I am looking for .NET info on getting tile graphics to the screen. What I know so far is this. I need a picturebox for the display. I need a second picture box for a back buffer and then I need a third picturebox for the tiles that I would copy to the back buffer which then gets flipped to the screen.I need this to be done with .net controls and classes or functions and etc. If anyone has good information on this, please let me know. I am using visual basic 2008 express edition.

I have a project running in my old computer. It has panels,textboxes,labels etc. It occupies the full screen when running.I bought a new computer with a widescreen format. When I run this project it only occupies 2/3 of the screen.
What properties of the controls must I use so that I can run this program in any size computer and still occupy the full screen i.e the size is proportionately resized depending on screen size.

I have following code to resize the form at run-time but it does not work. Form size remains same. What could be the possible reason?
frmErrMsg.btnNo_Err.Visible = True
frmErrMsg.btnOK_Err.Text = "Yes"
frmErrMsg.Height = 800

I have managed to build the basic Picture Viewer Program. Now Remember the program I am working on is for a Digital Picture Frame there is NO wirless network adapter on the old pc and there is no keyboard going to be attached to the laptop so the program must launch its self (ill put a short Cut in the windows startup folder). I got a picture box that excepts the picture file it covers the whole form! (when there is a picture in the picturebox1 it fits the screen) My form one covers the entire screen (I set the windows border from scalable to none). I need to make my program scan for picture files on different drives and then every 30 seconds or so choose a random picture from the usb drive and display it Posted below is my code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
PictureBox1.ImageLocation = OpenFileDialog1.FileName ' want to remove this feature so the user cant see this
[Code] .....
I am designing a program to be similar to Microsoft image viewer. I want it to open on PC start up Full screen and I want to make it scan for Images on flash drives with the user doing anything. I am making a Digital Picture frame out of my old dell laptop and I would like to make the program for it. How to have it play a random image every 30 seconds or so...

I've problem with clearing all the drawings I've created in my PictureBox. In fact I've created animation which stops after certain time and remains on the screen. The animation is created/painted with collection of about 25 TextBoxes - input of a user. Now I've added a button which clears all that info in TextBoxes and also should clear PictureBox -ictureBox.Refresh(). The problem is when I add new info in 25 TextBoxes nothing appears in PictureBox and I can't start an animation. Wondering why...

I managed to combine two .png images into one, and then display the result in a pictureBox image.However, the pictureBox seems to scale up my image! Makes it bigger!The pictureBox size is 96x128. The two images I have combined are 96x128. The pictureBox's SizeMode is set to "Normal"I have noticed that even though the pictureBox's image seems to be zoomed, it is cut to keep the 96x128 rect. But I don't want it to be zoomed...

There's a really simple way to convert images to icons:
Dim icon As Icon = Icon.FromHandle(bmp.GetHicon())
It also produces really horrible icons. Is there a better way to convert them, or more accurately, what is the better way to convert them?

I've been searching for days. I can't find anything that I think is going to work. I've probably read the answer and skipped it because I don't get it. I'm new. I've researched multithreading, sub routines and webbrowser. The webbrowser thing doesn't seem professional to me.
All I want is the animation to be smooth when it's displayed and to have it integrated into the app so it's not called from the local drive.The animated gif is in PictureBox3. Please point me in the right direction. I really don't want to use a static image.

Problem1: I have a picturebox on a form. I have also managed to draw several PNG files with transparency onto the picturebox (see below). However, If I move the form outside the border and move it back, the image is gone. My source so far:
Dim k1 As New Bitmap(My.Resources.image1)
Dim k2 As New Bitmap(My.Resources.image2)
Dim drawMe As Graphics = PictureBox1.CreateGraphics
Dim bgcolor As Color = Color.FromArgb(128, 128, 128)
drawMe.Clear(bgcolor)

My project needs to print a large PictureBox which during runtime only part of it is shown (as it's too large, width=4000 pixels and height= 2000 pixels) and to see the rest of the picturebox, user needs to scroll through the vertical and horizontal bars. On top of the picturebox, there are many controls which are loaded and positioned by user on run-time. Those include lines, labels, another picturebox
with image and user-defined controls. Now, i need to write a print function which will print that picturebox to not too many pages in A4 size or A3 size. Not too many means less than 5 for both paper size.
1) How can i print the whole picturebox with all its contents and go to next printing page until the whole PictureBox is printed? I tried using the following code but
(i)The image of picturebox inside that picture box and user-defined control are not printed whereas others are printed. Why is that so? How can i print the picturebox including both the "un-printed"?
(ii) Even i can print out the picturebox, only the part where the picturebox is shown is printed. How can i print the whole picturebox including those parts which needs scrolling to reach?
Private Sub CmdPrint_Click()
Dim rv As Long
'Picture1 is the picturebox to be printed.

If I try to draw a circle by using e.g.
Code:
e.Graphics.DrawEllipse(Pens.Red, 50.133, 100.321, 0.1, 0.1)
I will get an error message. I tried something like
Code:
Public ObjectPoint As PointF
Dim cpoint As New PointF()
cpoint.ObjectPoint = New PointF(startX, startY)
e.Graphics.DrawEllipse(Pens.Blue, cpoint.ObjectPoint, 0.4, 0.4)
but it didn't work for the location and the circle size. How to draw a circle(and rectangle) by using floating point numbers?

Ive been working on creating a side scroller game, and the back color of my pictureboxes needs to go. when transparent, it shows through the program and onto whatever is active in your Windows os(usually Visual studios).
I am trying to rip pixel color off of the background image picturebox( the level), and replace parts of the character picture box that show transparency with the level art. there may be poor logic in my code?
Heres my code:
Dim newImage As Bitmap = New Bitmap(PictureBox1.Image)
Dim backImage As Bitmap = New Bitmap(PictureBox2.Image)
Dim ximg As Bitmap = New Bitmap(PictureBox3.Image)
[code]....
not the best idea, but all i get is one color for all the level pixels placed in the new image, which is odd. any poor logic you see in this code that could allow the newImage.setPixel not to be 1 color? when i breakpoint, it is recieving different colors from the backimage.getpixel, but only putting one shade on for setpixel somehow. im not going for an accurate color read from the background yet, just wondering why im getting 1 pixel color for the whole picturebox background when being changed.
