Is there any routine I can call to reduce the size of an image file after
uploading a file from a client. I am looking to reduce file sizes
programmatically using C# in my web page after uploading. I know that
Photoshop can do it but I need to do it dynamically in my web page. I tried
doing it myself with some of the Bitmap thumbnail instructions but the
resulting image is very bad. I need a file reduction routine that creates a
good image that is smaller. I figured if Photoshop can do it then so can I
but how?
I am having a problem with this code. The problem I am facing is that the first image is displayed in its original size. But when I click the next button, the next image not displayed in its original size, but being displayed as 100 x 100 pixels, same goes to the 3rd picture and so on. Code:
I only need to know the height and width of the image.
It doesn't seem to be as easy as php's "getimagesize($imgFile);" method.

Which is a little bit shorter, and seems to work ok so far, but isn't there anything easier, like php's "getimagesize($imgFile);"?
i have a page that displays an image. the image path is a variable passed in the url link. eg. enlarge.asp?picture=http://www.hey/.com/you.jpg and the window it opens works. but id like to try and get the enlarge as to get the height and width dimentions so i can call a new window to opena popup and ill dynamically have the images dimentions to scale the popup to fit. and right after the javascript calls a new popup window itll use a close window function. and since it happens before the head tags it should be seamless as if i had a regular link calling a popup.
I have a table full of pictures with urls to images. Any idea how I could find out the dimensions of the images? i want to design tables to show them in a better way.
is it possible to have an asp script create a thumbnail of an image upon upload?
i want to create a rather small thumbnail and 65 x 83 and put it in a folder '/sized'
oh yeah, and one more quick thing.. i am pulling information from a database.. why is it that the symbol ' gets changed to a ? when pulling it from the field.. will this go away when i start adding information through forms instead of access?
The pic in the DB is just a named reference, as all the pics are stored in 2 common folders. 1 for the normal size pics and 1 for the thumbnail equivalents.
As this particular page has to be tight on space, I wanted to set the image as a percentage of it's size so I set the following:
Problem I have with this is that the browser seems to set all pics to 1 common percentage size rather than each being say 30% of each individual pic's size. This results in some piccies being completely distorted.
I don't want to go down the route of storing the x and y of each pic in the DB, so could you please let me know if I am doing something really stupid with the above.
My ASP app dynamically retrieves from db and sends JPG images using Response.BinaryWrite(). And it seems work. The script sets image type as "Response.ContentType = 'image/JPEG';"
But viewing image properties in IE returns Type and Size as 'Not available'.
I am writing a little script for an online album. The pictures' size varies a lot. I have a maxim size for every displayed picture because the layout of the page. So I want to resize the larger one to that size while leave the smaller one in their original size. Is there any script or code that can do this automatically?
I have an photo gallery, I want to create a button that opens a new window fixing the full size image snugley in it, which is easy.
But I want to get a script which detects the image size so i can use the variables to open the window.
What i want to not do is have to more options in the database with height and width in, and have to call them, although i'll do that if i have to, but i thought i would try something new.
I'm using Windows 2000 server n IIS I'm Using FileSystemObject of ASP in Server Every File and Folder has 2 Size when we get properties of any 1 actual size and Size on Disk.now my problem is when i get the file size from ASP object it give Size value but when i try to get folder size it gives size on disk and both values are different.
I'm creating a size to access limited size to upload files so i just check the folder size and then get size for those which are going to update by user then i will less those size to actual folder size to get remaining size.
I have a client who has had a ASP site with an Access database for several years. It stores information for the used cars on his lot. I have stored text in the database that points to the location of the image for each record. Each record will have a thumb image that is supposed to display in a list of vehicles available then the user can select an item from this list and a new page displays with the information and the regular size image. So far everything has worked fine exept for the display of the images which are stored in a separate directory called veh-photos. All I get are image place holders. I am using Dreamweaver 2004 and and Access 2000 for the database.
1.I want to show a image file of type '.tif' in the browser window; for that I'm writting as ASP code page.
2.This '.tif' type image can be shown better with 'Kodak Image Control'.
3.To have this 'Kodak Image Control' on my code page I just add it's ..ocx to tool box and then drag it from 'Toolbox' to the page.
4.Now after dropping this control to the code it's type is getting changed to 'object' instead of type 'ImgEdit'(and I think this is the reason I don't get correct result).
5.On one button's 'Onclick' event I'm calling a javascript function with which I'm setting a 'Path'and'Display' property of a control.
6.And want to show a image at location -- '..MFTDRCMF919685173-62.tif' which get shown in new browser window but could not get shown in that particular control. That means the path is correct, then what is the problem?
For better understanding of problem I'm pasting a following code which I've tried up till now...... .................................................. <%@ Language=VBScript %> <% OPTION EXPLICIT %>
<HTML> <HEAD> <META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
<SCRIPT LANGUAGE=javascript> <!-- function showpic() { var path; path = document.frmtif.path.value; alert(path); document.frmtif.ImgEdit1.Image =path; document.frmtif.ImgEdit1.Display; window.parent.self.open(path); }
I am creating a dynamic ASP VBScript page, which gets data from an Access database.
In the database, there is a field which holds a URL to an image. I can get the image to display fine, but where there is no file that matches the URL (i.e. a missing image) I want to display an alternative, default image (e.g. one that says "Awaiting Image"). The field is never blank, but the image file may not exist for all records in the database.
I think what I am trying to get to is the following:
If file exists (using URL from database to get location of image file) then display image using the url from the database as the image source else display default image - hardcoded in program endif
I have had a go and come up with the attached but I get an error with my if statement...
I'm working on a project where I'm suppose to upload a image to a server. The uploading works fine but when I want to change the image I uploaded to another image I can't get the filepath of the old image to show in my "filefiled"....is it possible to set a "value" where I can retrieve a filepath in a form if the input type is "file"?
how can I get size a file from any sites. http://www.domain.com/fileblablabla.zip I want to know what the size of file is by using ASP.. is there any way ? or is there any free component ? (But it must cancel immediatily after getting the size of file.. because maybe its size can be 50 Mb
I am using variable passing through the url, and as it is getting larger, I am finding that occassionally some values are getting trimmed. Is there a limit to how long a url can be?
how can I get different font size in the form method "select", "input" instructions working under ASP? because when I check with the browser is too big in the table.
I have a drop-down with 40 option values and only one option should be selected of the 40 options. The list size should be 1.
When I click on the list, it drops down 30 options (a very long list) with a scrollbar for the last 10 options.
Is there any way, when I click on the list it drops down only 5 options (as if the list is of size 5) and allow a scrollbar to browse the remaining 35 options.
Code is: <select name="deplist" id="deplist" <option value="Commerce">Commerce</option> <option value="Instru">Instrumentation</option> ... similar such 38 options </select>
I need a general code for limiting an image size in pixels.Uploaded Images from people may not be larger on width than 400 px. If so than a script would minimize them to 400 but if they are 260 px then they of course appear in 260 px
