How To Create A Simple Watermark On The Fly For An Image
Apr 20, 2010
I'm looking to create a simple watermark on the fly for an image, taking one image (JPEG) and adding some text to it on the BOTTOM of the image in white, with a solid black background right across the bottom. haven't been able to find anything that does it on the bottom of the JPEG.
I am trying to create a watermark image on the background , i am wondering what option can i use to call image file from my APP_Themes folder insteaed of my hard drive ) Currently i am using this but couldn't figure it out how to call from APP_Them folder of application rather than being specific.
i have a page where the image,logo,position and alpha details are shown in a gridview...and the page has a confirm button...once the user clicks on confirm button[then actual watermarking happens which gets stored in db] it navigates to another page where another gridview is present but it has an additional column [watermarked image] ...the only problem is that when i want to write code for watermarking in the watermark.aspx.cs page
how do i watermark image, example: when a user registers on the website before the user uploads his or her photo there is a default image and when the user brings mouse close to the image it will show "Update profile picture".
I need to create a database in SQL2005 on a webserver (manually (not in code)), have registered users upload an image to a webserver not overwriting if the filename already exists but to append if required Weekly, I wish to review the uploaded images in the uploaded folder, create a user & add the image(s) into the database programmatically for all users to be able to search / When the image(s) are in the database & are searched or shown (ex: profile shown with all those details/pics displayed but before displaying the pics on the form to watermark them. However, a profile could have 1 pick or it could have 20. I would like to have for example 4 pics being shown then the user to click next till the end of the recordset. Then do the same for another profile. Uploading the file is fine but not to append if exists then maybe I should have an upload date as the filename (haven't decided)
There is an image for the surface, and a text is written on the image for 184 rows of date.. Thus, it is expected to see 184 different text written image files are generated with all the same background images. (The code is declared below...)
The problem is that the first text is written for all 184 different data.. I think I have to remove something in the loop. But what is that ??
Is there any way in order to remove a watermark from an image? What has to be done is to lose the existing watermark as much as possible and place a new watermark text instead. As the existing watermark is placed diagonally, cutting the image in two equal parts (triangles), I am thinking of possibility to detect the diagonal and then determine the watermark text height (size / dimensions), and after that apply the Gaussian method of blurring (or anything similar) on the determined part. After it's edited, the image would be exposed to a code that would generate the new watermark.Is this possible to do, after all?
I want to save water marked image to database.i have done watermarking,but save the image it does not save to database.
Following are my code:
Bitmap original_image = new Bitmap(FileUpload1.FileContent); string sWaterMark = "reshu";//String to be watermarked int fontsize = ((original_image.Width * 2) / (sWaterMark.Length * 3)); int x = original_image.Width / 2; int y = original_image.Height * 9 / 20;
How to add watermark to uploaded doc (pdf or image files).The workflow will be-User register at portal -> user upload some required document (like financial proof or some kind) -> When saving them to database -> a watermark (predefined by admin at backend in admin panel as - Logo or Text) will be added to those uploaded document on top and bottom or wherever possible on the uploaded document.
So in future when admin views the document uploaded by him in his account, it will be displayed with stamp or the watermark. It will prove that the document is uploaded to server by user or whatever. Now, this we have found way to do in jpg, but in case of pdf its quite tough..
I am doing a project on digital watermarking. This is the process. The user will choose his image file to upload, chooses his image key(either from the visual studio gallery-folder name is Image Key, or he chooses his own from the directory).
He enters a password, and this password will be embedded into the image uploaded.
Next, there is an option to digitally watermark the image (This is where I am having problems - stuck with the codes)
Here is the work so far, and I couldn't get any further.
I have a page that display like a print pre-view. It shows the watermark in the background. But when I print it, it doesn't include the watermark. I know in IE7 you can change your IE settings to make it print the water mark but in IE8 you can't do that. Is there another way to print my water mark out? Here's that part of the code:
I have a simple page with 4 thumbs. All I want to do is when the mouse is hovering over a link, the thumb to move up like it's hovering. When the mouse leaves the link, then the the thumb moves down to it's original spot.
I can't seam to find any tutorials on how to create that effect. I tried bing and google but none of them are what I'm trying to do.
