1. INTRODUCTION TO WATERMARKING

It has always been difficult to associate text with images. Most often an image editing software such as photoshop, Flash or 3dsmax etc are used to associate text with the image. This requires multimedia or DTP professionals to work on those images.
The application to be developed includes a GUI rich front end that would allow the users to choose a bitmap at runtime dynamically. The text to be embedded is also accepted at runtime. The concept of watermarking is performed to associate the text permanently on the image without having to edit it. The text is carefully placed in to the image not affecting the image during the process. The embossed text is then available for applying filters to determine its prominence over the placed image.

A facility to apply filters (opacity) on the text is provided. The brightness of the text can be adjusted as per the client requirement. The position of the text is adjusted to the top, bottom or any location of the images.

If the source image is not in index pixel format then it cannot be readily used the conversion module allows the image from a different format to be converted into the jpeg format. This enables the source image to be of any format.

1.2 Existing System
The present system involves making of watermarked images using multimedia software’s. This third party software has to be used to create these watermarked images. Other software’s such as Paint brush can be used but is not user friendly when it comes to edit text. Software’s such as PowerPoint allows good usage of text and images but the text and image exist as different layers and hence it is not in accordance with the principle of watermarking.

Few software’s in the above requires multimedia knowledge and hence not user friendly to every user.
Text editing when using paint brush is not customizable.
The time taken to watermark an image would depend upon the skill of the designer.
When large number of images have to be watermarked it is not permissible to use multimedia software’s for instant results.

1.3 Proposed System
The system proposes to create a user friendly graphic rich tool to perform watermarking.
The system identifies the source image (indexed pixel format) and text which is then embossed on the image. The brightness and contrast of the placed text can be controlled by the end user using opacity. The user can be any layman and still use the tool to impose the text on the image. It thoroughly isolates the requirement of any multimedia software’s or designers. Any number of images can be watermarked one by one without much of a delay as it would happen in the case of using multimedia software’s. The tool is fast and reliable. Additionally for images that do not match in format for being watermarked, conversion facility is provided to alter the image to the recognized format.

Does not require any multimedia software or designing knowledge.

The text can be altered or redrawn without using any tool.

When large number of images is available to watermark the process can be done sooner.
An easy to use graphical user friendly tool that has less maintenance or data loss.
