INTRODUCTION

Image Converter Software is made in Java Environment which can run on

any operating system.

At a time, it can convert large amount of BMP/PNG/GIF images to

JPG/JPEG image format with same dimension and resolution.

When bmp images are converted to JPG images, its size extensively

reduced but dimension and resolution remains unchanged.

You can convert image to Byte Array & store in Database and whenever

require, it can be retrieved.

SYSTEM AND SOFTWARE REQUIRED

Operating System :

• Windows XP.

• Windows 7.

Java Platform :

• Version 6

Database :

• Microsoft SQL Server 2005 or MySQL.

IDE :

• Eclipse IDE for Java

Creating Table In Database (MS SQL Server)

To Create a Table :create table s_pht(

pht_kid int primary key not null identity(10,1),

pht_name varchar(50) not null,

pht_file image not null)

Table Name : s_pht

3 Columns : pht_kid, pht_name & pht_file

To See Content of Table :select *from s_pht

pht_kid pht_name pht_file

In order to write a java program in Eclipse IDE, steps may be as follows :

Selecting File/Directory For Old Path

By clicking on Browse Button which is in front of Old Path, File/Directory

chooser will open.

Path of selected file/directory will automatically copy to the corresponding

Text Field.

Selecting Directory For New Path

By clicking on Browse Button which is in front of New Path, Directory

chooser will open.

Path of selected directory will automatically copy to the corresponding

Text Field.

Conversion of Images to jpg/jpeg format

When Button “Convert” is clicked/pressed, all images from source

directory(Old Path) is converted to JPG/JPEG format and stored at

destination directory(New Path).

Disruption of Obstruction During

Image Conversion

If old path and/or new path are not provided then an error message will be

generated.

BMP Image Vs. JPEG Image

A bitmap(BMP) file is one that is made up of pixels in a grid. It is a

resolution dependent image, so it’s very difficult to increase the size of a

bitmap graphic without a noticeable decrease in quality.

Joint Photographic Experts Group (JPEG) or JPG files are a type of

compressed bitmap file. This lossy compression technique reduces the size

of an image by discarding details that are typically too insignificant for the

human eye to detect.

JPEG file format supports 16 million colours, it does a very good job of

analysing what data is the most important to a particular image.

Save Image To Database

When Button “Save To DataBase” is clicked/pressed then all JPG/JPEG

images at “New Path” is save to the database in byte array format.

Images Stored In Database

JPG images are stored in database in Byte Array format.

Each images stored in database with unique id.

Images in Byte Array FormatUnique ID

Disruption of Obstruction During

Saving of Images in Database

If New Path is not provided then an error message will be generated.

Continued……. If program is not successfully connected to database due to invalid user,

password, driver, etc. then an error message will be generated.

Retrieve Images From Database

When Button “Upload” is clicked/pressed, images from database which is

stored in Byte Array format is uploaded at Old Path location in JPG

format.

Disruption of Obstruction During

Upload of Images From Database

If Old Path is not provided then an error message will be generated.

Continued……. During upload, if program is not successfully connected to database due to

invalid user, password, driver, etc. then an error message will be generated.

ADVANTAGES

Java based program which is platform independent.

Portable

Image takes less memory space.

Takes very less amount of time in conversion.

No effect on image quality and dimension.

Data stored in database is more secure.

Each images stored in database with unique ID.

If you need to convert one or thousands of images of varying types, this is the

tool.

A BMP image having size 5MB is converted to JPG image then it’s size reduced

up to 700 KB but image quality is unaffected.

Instead of storing the image, you can store the byte array of that image in DB. You

can convert that image to byte array & store in DB. Byte Array (Base 64 string)

which is more secure.

It can be used in various places like Banks, UIDAI (Aadhaar), photography etc.
