Refering To Stretching The Image Or Resizing The Picturebox?

Sep 1, 2011

Ok, it seems my question might not have been straightforward, so here is a more generic question.On a form in a picturebox if I have a 32 x 32 picture. How can I scale it to be 64 x 64.I am not refering to stretching the image or resizing the picturebox. I mean using the ScaleTransform method of the graphics class. How can I do this without deforming the image?

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

C# - Resizing Image To Fit On A Printed Page?

Sep 26, 2011

I am trying to print an image (from file) to a the printer using a PrintDocument.I am re-sizing my image so that it is scaled to be full page on the printout when I print this the image is cropped slightly.

EDIT 2:I am using the margins to calculate the area to use:

With printSettings.DefaultPageSettings
Dim areaWidth As Single = .Bounds.Width - .Margins.Left - .Margins.Right
Dim areaHeight As Single = .Bounds.Height - .Margins.Top - .Margins.Bottom
End With

The bounds of the page are 1169x827 (A4) and with the margins it is 1137x795.After resize my image size is 1092x682 and I am using the following code to draw it:

e.Graphics.DrawImage(printBitmap, .Margins.Left, .Margins.Top)

The annoying thing is that when I print to the PrintPreviewDialog it is scaled perfectly but when I print the exact same code to the actual printer it does not fit.

EDIT 3:Full code can be found at this url Usage:

Dim clsPrint As New clsPrinting
With clsPrint
.Landscape = True

Manipulating / Resizing / Scaling An Image

May 24, 2010

Imagine I have a rectangle say 400px x 300px. All of this is very easy using Sytem.Drawing. DrawImage. But then I want to leave the left hand side as 300px but change the right hand side to 250 px. I can draw the box using 4 DrawLines but I don't know how to squash the image into the new shape. I want the right hand side of the shape to be 250, the left size 300 and the top and bottom 400px.I can't use DrawImage as it expects the left and right sizes to be the same. Is there a way to manipulate the image into the new shape?I've looked at other questions, but they only apply where the left and right hand side is equal.Any thoughts on how to squash an image into a shape which did not have parallel sides?

Asp.net - After Resizing White Image Gets Gray Border?

Jul 25, 2011

i was searching google for some kind solution and i found one, i tried to implement it in my code but it doesn't work. The problem is that after resizing white images they gets gray border.Here is the link of soloution i found:It says:

This problem is occuring because you are interpolating your image data to a new size, but along the edges there are no pixels to interpolate and .NET uses black pixels for these edges by default. To fix this you need to use an ImageAttributes class in your DrawImage call....

https:[url].....

CODE 1: And this is my code WITH IMPLEMENTATION OF ImageAttributes:

Private Shared Function ResizeImageFile(ByVal imageFile As Byte(), ByVal targetSize As Integer) As Byte()

Using oldImage As System.Drawing.Image = System.Drawing.Image.FromStream(New MemoryStream(imageFile))

Dim newSize As Size = CalculateDimensions(oldImage.Size, targetSize)[code].......

Open Image File And Save After Resizing?

Dec 27, 2008

Code that opens image file this code works properly
Private Sub MenuItem4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FromFile.Click
PBDisplay.Visible = False
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
PBDisplay.SizeMode = PictureBoxSizeMode.AutoSize
[Code] ......

This code is what I am using to save image after it is re sized, It will not save the new image, it saves the old image and the old size. I am using a picture box to import the image into, then I am resizing the picture box and the image. But when it is saved it reverts to the original image.
Private Sub MenuItem6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click
If SaveFileDialog1.ShowDialog = DialogResult.OK Then
PBDisplay.Image.Save(SaveFileDialog1.FileName)
End If
End Sub

Resizing Image Before Uploading To Local Storage

Jan 6, 2012

I want to resize the resolution of an image before uploading it to local storage. Right now it saves the image in its full resolution and I have to manually resize it using width="200" height="200" or a css tag in aspx. I want to reduce the file size of an image before storing it, hence by resizing the image resolution when the user uploads it via button. I've tried using System.Drawing before and setting the int imageHeight and int maxWidth to be resized but couldn't seem to get it to work.

My code so far is:
Protected Sub btn_SavePic_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn_SavePic.Click
Dim newFileName As String
Dim SqlString As String

PictureBox - Image: Select The Path To A Local Folder That Is Within The Application And Get An Image From It?

Sep 15, 2010

I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.

This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .

So I have made a folder named "Pics" inside my application and added two images into it.

How do I get to this local folder in the following code?

Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )
