I have a page which allows the user to upload pictures. The problem is that my old users can't resize the image themselves. I want to allow them to upload any size of image and then when the server gets it, it will create a small copy of this picture.
I want to know some codes on how can i resize the selected image in fileupload control and then Upload it in MS Access Database. I am using VB in coding. The only thing I know is that I can save it as an ole object in the database and it will be saved like a string. But I don't know some codes for this one.
I need to resize a photo selected by a user with a fileUpload control and upload to a database. What i can just do now is upload the image to a database table. Imjust trying to find out how to code the image resizing part and when i say resize, i mean the dimensions and file size.
I have read about the file upload control in asp.net and tried it and works great. But I want to know if I can use it for another purpose. I have a video capture control that can be used for webcam apps or anything else. It has a method called HTTPUpload where it will upload an image file to the server using the HTTP upload protocol. My question is can i use the .net FileUpload control for this? And if so, how can I pass the image file straight to the .aspx page without having to submit a button? Would the file be as a query string variable?
Arguments: WebServer = web server address WebPage = name of upload web page Fields = list of 'fieldname' and 'fieldvalue' values delimited with '|' Files = list of 'fieldname' and 'file path' values delimited with '|' Returns TRUE if successful, or FALSE otherwise. Example vcx.HTTPUpload "[URL] , "upload.asp", "field1|value1|field2|value2" , "file1|c:foldermypic.jpg|file2|c:foldermyvideo.avi"
In an .aspx page with the vb.net codebehind i am using IFRAME , which would be created inside the repeater control. Since i want to resize the IFRAME based on the content within the page i have been using the resize function Obtained from here on the IFRAME onload as shown below.
However it is throwing the error as the method could not be found in the form. Is there any client side script variant for the onload event? May i know,What might be the reason for the error and its solution?
I found this code on another site and it works great for resizing the image and keeping the quality. What I want to do at the end is check the height of the image and if it exceeds a certain number, just change the size of the image. Not resize it but just cut off part of the bottom to be a certain size.
Code: Dim image As System.Drawing.Image = System.Drawing.Image.FromFile(src) Dim srcWidth As Integer = image.Width Dim srcHeight As Integer = image.Height Dim thumbHeight As Integer = (srcHeight / srcWidth) * thumbWidth Dim bmp As New Drawing.Bitmap(thumbWidth, thumbHeight)
i am using file upload control for uploading images. in that iam checking the condition,if Image.Width > 250 || Image.Height > 400 then i am resizing the image. but it is giving the error "The SaveAs method is configured to require a rooted path, and the path 'ProductImages/roman_sandals.jpg' is not rooted."
ProductImages is folder where i am saving image. Can anyone find why this is giving error,my code is
display images in small size (thumnails) and also resize the image size (kb) so the page will quickly upload images. i dont want the user will upload 2 version of images (large and small) and i dont want also to resize the image size while uploading the images to server. I want the user will upload the original images (320x480 px) and when the users will watch the gallery they will see small images (120x180px) with small kb size that will uploads fast.
I have a working application to save an image file to my sql database (Saves as "Original_Image" in the DB TBL_ImageGallery). I have a file limit on the upload of 1 MB. This also works great and the image is being saved beautifully. I found a bit of an issue. Being i am working on a network with 2 bonded T1 connections the streaming of images to my site, when tested internally, is effortless. I am not sure that this will be the same with a generic bandwidth. I want to store the original image size into the databse (already done) but also store a smaller sized (in bytes not actual size [Width, Height]) to my database in a "ThumbNail" column. This will allow the browser to only have to pass the "Thumbnail" sized image, obviously this needs to be much smaller than the original (ex: 1MB orignal I want to save as 12KB image in the thumbnail column), to the thumbnail img control in the user's interface.
I am not sure if this is possible or if there is a need of third party controls. I am interested in doing this as either a stored procedure or in the C# code on an event fire. There may be a better / other solution to this and if that is the case I am also interested
I am searching for a way to resize and crop images to a specific size in a fixed ratio like 16:9. So I have any image and any size and it should be resized and cropped in a ratio 16:9.
Just cropping is not very nice. I want that the image is resized more and if necessary maybe cropped. Or better: I want to reuse as much as possible from the original image but resize and crop it centered so I could use it in a fixed html div with a ration of 16:9.
