I have a folder of images that I would like to loop through them all and resize each one to have a max of 100 in width or height, I have looked at the samples out there but none indicated where I can set the width and/or height and it will do it automatically, I would like to save the file in a new directory once I resize it.
View 4 RepliesI'm using a web cam that takes 320 X 240 pictures. This sort of gives the picture a "landscape" look to them, and I need to re-size the pictures to a 169 X 225 "portrait" picture. Its for a badge program. Anyway, when I re-size the pictures, they get all scrunched up because of the difference in aspect ratio. Is there a way to re-size the image and the aspect ratio at the same time? Would this be considered cropping or resizing? I'm a little confused on where to begin. I mainly use VB, but if someone has a good example in C#, ill take the time to convert it.

View 5 RepliesHow can I build a cropping tool such as the one in Office Picture Manager as seen below? Notice that as soon as the Aspect ratio is selected a cropped area shows on the picture that can be dragged to the perfect position creeping the aspect ratio in tact. This is why I wanted somehow to link my app. to Picture Manager. I want the picture to open in Picture Manager, cropping tool already selected, ready to be dragged to the perfect position. Unless you have some code that can do jut this.

I have the need to maintain a 4:3 aspect ratio on a Video control on a form. The forms (there could be up to 16 in a 4x4 layout) should all maintain a 4:3 aspect ratio when resized depending on clients monitor/resolution. The forms have a border and will keep them. The control is set to fill the form and is the only control on the form. Here is code that I use to create the initial layout:

View 3 RepliesDoes anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.

View 6 RepliesI would like for a user to upload an image to a file in my web application. However, before being saved I want to resize the image to a specified size. I have found code on the Internet to do what I want but I am having trouble adapting to meet my needs. Here is the part I am having trouble with:
' Resize Image Before Uploading to DataBase
Dim imageToBeResized As System.Drawing.Image = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream)
[Code]....
Rather than upload to a database I want to save the image to a folder in my web application. The problem I have encountered is that VB won't let me save a byte() to a folder. Not sure what I can safely change to adapt for my purposes. Why does it need to be changed to a byte() in the first place?
I have an app that displays images (using picturebox component). what I am trying to do now is to try to allow the user to resize the image how he wants it (scale). for this i think I need to create an instanece (bmp) clone of the selected image in the picturebox and draw it ontop of the original picture; then specifi new set of size points.I was trying to use the code below:
Graphics.FromImage(PictureBox1.Image).BeginContainer('i do not know what to do here')
I need to specifi the new size of the graphics container but I do not seem to have any clue on how to do it.

I wrote a piece of code that grabs a fileupload, puts it into a memory stream, converts the main pic, and thumbnail pic, then saves them as jpegs, then updates the database.
Everything works fine, except one little glitch. If the DPI is above 300 then the image doesn't save right. It get's pixelated and blury.
here is the code.
Dim fileLen As Integer
# Dim myStream As System.IO.Stream

View 1 RepliesI am new with visual basic 2008 express edition. I wanted to ask on how to resize an image in a picturebox with a set height and width.[code]...
All it does is open a file with open dialog filters. I have a set height and width for the picturebox. If i open a picture with a height and width greater than that of the picturebox, the picture box will only display a portion of the picture.
I am trying to figure out how to go about my two problems i am currently having when trying to display a resized picture into a picturebox on my form.
What does it need to be in order to grab the image thats already been cropped in the pbCrop picturebox? I have the cropped image in the pbCrop picturebox and i then am trying to resize it.[code]...
I have a form where i load an image to a picturebox. I open a dialog to prompt the user to grab a file and once that is done i pull the image into a picturebox. Now i want to resize all incoming images but.... because of how it affects my ability to draw lines in the picturebox i am restricted to leaving the picturebox size mode set to normal. So i set out to write a resizing function.
The issue i am having is that eventhough i pass the function an image. I get the Height and with from the image object and it appears that i should be tripping some of my IF/Then statements ... neither Scl or Scl2 ever gets set which in turn keeps nw_height and nw_width from setting themselves properly.
All 4 of those variables stay 0 at all times and im not sure why.

I have this fingerprint scanner I'm working with. The fingerprints taken are index/stored in our imaging system and the fingerprints are put on certain documents and printed.When I scan the image in and then load it into a bitmap object, the width and height are (w:480,h:640).Now if I open this file in any image viewer and print it from there the finger print is as big as a fingerprint should be.Now when working with it in code, it's huge. I have found some resize code online, but the resulting image is horrible.Is there anyway to resize an image while taking in account the dpi and such so the image is highest quality (same as print out?).
