Web Forms :: Adding Watermark Or Text To Images On Uploading Or Displaying?
Oct 31, 2010
Is there a way to process images once uploaded to my asp.net site, to put a watermark or some text across the image to copyright the images? I would like to do this server-side if possible.The other option I have discovered here [URL] would be to store the images as they are on the server, but to manipulate the display so it appears the image is watermarked . However, this solution is in PHP. Does anyone know a good PHP to VB.NET translator?! Or does anyone have a good suggested link, idea or code? Or can I add PHP to my ASP.NET site?
post the C# source code for uploading images to a database, and then showing it to the user?? I have tried now for 3 weeks with no luck... Maybe we should recommend to Microsoft to add a file upload html helper method to MVC 3?
[Code]....I am seeing an empty text box watermark css is not applying and the text type first name here is also not getting displayed insde the text box.
I need to add Images in my Rich Text Box editor after a paragraph. I have gone through this article and it is very useful.
{URL] ....
But I have some question:
1. Can I add multiple images in this Rich Text Box.
2. After adding images and content in Rich Text Box, I want to save it in database. So where will I save images and content. I mean images in folder and content in database or both in database.
In my project i have a table named WATERMARKED_IMAGES where i have columns like WID,IMAGE_ID,LOGO_ID,POS,ALPHA,SECRET_KEY[IMAGE_ID and LOGO_ID here are the foreign keys]....i need to retreive IMAGE_CONTENT from another table IMAGE using IMAGE_ID ..the same way LOGO_ID also...after retreiveing i need to embed the logo in the image at the pos and with alpha value mentioned in the table WATERMARKED_IMAGES...
but the problem here is that as i am able to retrieve data IMAGE_CONTENT,LOGO,CONTENT,POS,ALPHA in a single query] from database but i dont know that how to use this detail and where to use these details in my WATERMARK class...
i am doin my final year project and in my project i want to watermark multiple images simultaneously where image,logo,position,alpha and key value is stored in a database table ....i need to retreive these details from db table and perform watermark on those images....
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.

My problem is that I want to display a watermark on password field i..e Enter Password. But it is appearing as **********. I have seen it on facebook that when i see it first time text is appearing 'Enter Password' and when i enter my password it appears as *****. I know that with some dirty workarounds I can fix it. Is there any good solution for this here is the code which I am using
I have 2 "Updatepanel" controls. Each contains a textbox linked to a "TextBoxWatermarkExtender", and a button. When I click on one of the buttons without to enter any text, all the watermark text disappear on BOTH updatepanel when they should remain visible.
[code]...
How can I avoid the waternmark text to disappear when I click on the button?
