I use some code to successfully resize and save images - but I want to save the image to 800x800 px size on a canvas of 900x900px so it has a white border type thing around it.
View 8 RepliesI have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).
I want to programatically delete some pixels that are unused in order to reduce the image size.Can anyone tell me how to reduce the size of an image file without changing the pixels values..
View 1 RepliesThe object is to load an image into a picturebox, then save a new copy of the image in a different location, but with the height and width of the image box not the original file's height and width but I can't figure it out. I've got the loading and saving working no problem but getting it to adopt the new size is stumping me, it just keeps saving with the original file's size properties

I'm writing a Cleint/Host program that sends a image over tcp (from printscreen, not a file) to the host. Everything seems to work fine and the image is transmitted and displayed in a picturebox plus saved to a folder. The problem is when the printscreen is bigger than 176040 B. First the limit was 128000B but after setting the sendbuffersize and recivebuffersize to 1000kb the limit is 176040 B. Could it be a limit in the tcp protocol?

View 1 RepliesI have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.
I tried:
picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)
But this just changed the the size of the whole picturebox, rather than the image within it.
I'm currently working on a school project. And a part of the program is to 'change' the images. All images added are BMP-files. But the output has to be JPEG. Now there are 2 other problems:
- The width of the image should be between (70-165 ) Pixel and the height between (65-185 )Pixel
- The filesize of the image should be between (3-4 KB)
I know how to change the width/height, but it's hard to make the filesize between 3-4 KB.
I have several images that are going to randomly display in a picture box on a vb.net form. My question is, is there a way to auto-size the picture so it "fits" into the picturebox?

My users uploads a picture and the picture get saved into my SQl Server Database.My users view the picture on the page in a normal Image WebControl with size 150px by 150px - example can be found[url]...
If the user uploads a picture of 300px by 200px the image will look funny in my static 150px by 150px Image box. Any idea how i can display the Image so it wont be fuzzy?
Also, how can a have some form of pop-up that will appear on the screen, showing the actual size of the picture from the database when the user clicks on the 150px by 150px Image.
Note: I dont want the Image static size to increase as this will totally mess up my page layout and look. It must be some form of pop-up or something. Something i have seen before i think was really cool. User clicked on the small image and then a pop-up appeared in the middle of the screen with the actual size of the picure and everything ells on the page was disabled until the user clicked on the close button.
I'm using this class. [URL]. Is there a way for me to set the output image size? The size is too big for what I need. Any way to shrink it to suitable size?

As you can see I figured out how to autosize the PictureBox (candypic) to the size of the image coming in....just cant get the image to come in as the right size.....

View 3 RepliesI have the following barcode image:

When this PDF is generated, however, the image is appearing larger than expected, and is distorted:
I can't see anywhere where I'm setting the image to be a specific size, so why would it distort like this? And how can I prevent it?
It's crucial that this image remains the size it is intended to be so that it can be read by barcode scanners.
