Question?Can graphics files be encrypted?

Obis sly  you can encrypt a graphics file. After all, most encryption 

algorithms don't care about the intellectual content of a file. All they 

chew on is a series of byte values. Therefore, most any encryption program 

that works on ordinary text files will work on graphics files as well.

Why would you want to encrypt a graphics file?

 Mostly to control who canview its contents. You can invent a proprietary file format and that mightslow a file format hack down for, say, five or ten minutes. You could add a proprietary data compression scheme, possibly a twisted variation of a already public algorithm. 

Realize that an encrypted graphics file still might not be very secure. 

For every data encryption algorithm there exists at least one method of 

getting around it, although it may take hundreds of computers and many

years to fully employ and execute that method! 

XOR is very simple and fast, which is a must for a graphics file 

translators/viewers that must decrypt a file on the fly.  A short key might be very easily discovered in this way.

The SMPTE DPX file format supports such an encryption feature.If you wish to use a public key/private key encryption method, then 

storing the public key in the file format header (usually as a 4-byte 

field) and only encrypting the image data would be the way to go. 

If you really need to make the contents of a graphics file secure, then 

I'd suggest not only using some form of data encryption, but also create

an unconventional and proprietary file format and do not publish its 

format specification.

Can graphics files be infected with a virus?

Most graphics files, however, contain only static

data and no executable code. The code that reads, writes, and displays

graphics data is found in translation and display programs and not in the

graphics files themselves. If reading or writing a graphics file caused a

system malfunction is it most likely the fault of the program reading the

file and not of the graphics file data itself.

With the introduction of multimedia we have seen new formats appear, and

modifications to older formats made, that allow executable instructions to

be stored within a file format. These instructions are used to direct

multimedia applications to play sounds or music, prompt the user for

information, or display other graphics and video information. And such

multimedia display programs may perform these functions by interfacing

with their environment via an API, or by direct interaction with the

operating system. One might also imagine a truly object-oriented graphics

file as containing the code required to read, write, and display itself.

Once again, any catastrophes that result from using these multimedia

application is most like the result of unfound bugs in the software and

not some sinister instructions in the graphics file data. Such "logic

bombs" are typically exorcised through the use of testing using a wide

variety of different image files for test cases.

If you have a virus scanning program that indicates a specific graphics

file is infected by virus, then it is very possible that the file

coincidentally contains a byte pattern that the scanning programming

recognizes as a key byte signature identifying a virus. Contact the author

(or even read the documentation!) of the virus scanning program to discuss

the probability of the mis-identification of a clean file as being

infected by a virus. Save the graphics file, as the author will most

likely wish to examine it as well.

If you suspect a graphics file to be at the heart of a virus problem you

are experiencing, then also consider the possibility that the graphics

file's transport mechanism (floppy disk, tape or shell archive file,

compressed archive file, and so forth) might be the original source of the

virus and not the graphics file itself.

What do Graphic Designers do?

What do Graphic Designers do?
Graphic designers use a sophisticated level of design to create advertising, illustration, logos, websites, and other visual materials for their clients. These trained professionals work alone or in teams, under the supervision of art directors and alongside copywriters, to generate interesting, unique images for their client base.

The most successful graphic designers pair their creative ability with technical knowledge and a professional level of communication. Because about 25 percent of graphic designers are self-employed, business skills as well as creativity are important. So, thinking is good factor in Graphics designing world.

Spend some time of a Graphic Designer
The individual duties of graphic designers depend highly on their job descriptions. For those who are self-employed, the job can change on a week-by-week basis or time to time, with a number of projects requiring daily attention one week, and a lack of work the next and get ready for tomorrow. Wage-and-salary graphic designers generally have a more stable work week, although deadlines and other requirements can lead to a work week that exceeds 40 hours or depending on the situation.

I can do that without a graphic design school or program! Is there anything else that I’d be missing?

Well, a load of potentially strong connections for one. Your classes would be filled with like-minded people that are interested in a lot of the same things as you. Most often, schools will have connections in one way or another with the industry. Some employers almost have a partnership with some of these graphic design schools.
You will most likely miss some of the teamwork aspects of things, which can be really important if you end up at a graphic design studio. Learning to work along side with others can be really important. This is most often a part of the graphic design program.
You can ask your educators or classmates questions about anything you are unsure about. You can get feedback and critiques, learn and grow a lot faster in a class environment. In a solo environment, you have no real way to measure how good or bad you are, and if you are on track or missing the mark.
Most good programs offer a work practicum, which is a great way to get your feet wet with some experience, and at the same time, potentially land you a job where you’ve been placed.

What is raster, vector, metafile, PDL, VRML, and so forth?

What is raster, vector, metafile, PDL, VRML, and so forth?

These terms are used to classify the type of data a graphics file contains.
Raster files
Raster files (also called bitmapped files) contain graphics information
described as pixels, such as photographic images.

Vector
Vector files containdata described as mathematical equations and are typically used to store line art and CAD information.

Metafiles
Metafiles are formats that may contain
either raster or vector graphics data.

Page Description Languages (PDL)
Page Description Languages (PDL)are used to describe the layout of a printed page of graphics and text.

Animation formats are usually collections of raster data that is displayed
in a sequence. Multi-dimensional object formats store graphics data as a
collection of objects (data and the code that manipulates it) that may be
rendered (displayed) in a variety of perspectives. Virtual Reality
Modeling Language (VRML) is a 3D, object-oriented language used for
describing "virtual worlds" networked via the Internet and hyperlinked
within the World Wide Web. Multimedia file formats are capable of storing
any of the previously mentioned types of data, including sound and video
information.

Do I really need to get a graphic design degree?

Many high school students that are interested in a graphic design career wonder if it is really necessary to attend a school and get a degree or certificate in graphic design. Do I really need one if I’m really artistic to begin with? They can be great at sketching, painting, and so on. Others might have some good experience working with software such as Photoshop, Illustrator, Flash, and so on. They think that since they understand software, and have gone through the tutorials, that they can do this graphic design thing. You might have a chance if you can piece some of these things together, and the employer isn’t at all picky. You might be able to fluke it.
But graphic design is not just about creativity and / or software. Graphic design is about visual problem solving, and meeting the needs of the client. It’s not about making something look cool, but rather to sell a product or an idea visually in a captivating way. A good graphic design school or program will mold and shape you so you can do just that.

The Scope of this Industry...

So what do graphic designers actually do? I'm sure most people can name at least a few things, but the graphic design spectrum is perhaps broader than you think.

Designs can include: brochures, posters, magazine covers, magazine layout, tickets, business cards, T-shirts, signs, logos, book layout (typesetting), importing advertisements into a newspaper, websites, cd covers, dvd interactivity elements, Internet banners, flash animation, web interfaces, Powerpoint presentations, and more.


So what can YOU expect? Some employers will have a very specific and narrow job description, and some will want you to do a whole load of stuff. Often an in-house graphic designer (meaning a non design company will hire someone to do their graphic design rather than work with a company) will be the jack of all trades. You might expect to create the website, brochures, a poster for an upcoming event, and prepare powerpoint presentations. And then there is the other end of the spectrum where your entry level job for the first 2 years is scanning photos for Auto Trader Magazine, and placing them into the layout. It all depends on who is hiring, and what they want.

Do you have an interest in art, computers and problem solving? If so, graphic design might be the career path for you.

But What is Graphic Design?

Graphic design basically is visual problem solving using text and/or graphical elements. Your aim is to create something that is pleasing to the eye, and gets the attention of the viewer. But things can't just look cool. They have to work as well.

How effective is a great looking restaurant menu if you can't for the life of you find beverages, or it's hard to tell which price is for what?

"Graphic design is the process and art of combining text and graphics and communicating an effective message in the design of logos, graphics, brochures, newsletters, posters, signs, and any other type of visual communication. Today's graphic designers often use desktop publishing software and techniques to achieve their goals."

"The practice or profession of designing print or electronic forms of visual information, as for an advertisement, publication, or website."

You should have good idea.

You should have good idea about what kind of designing software you need?
See, in current world there are thousand of designing software which everyone is not enough good for your tusk. So you need to know what kind of designing software you need. Ok I am explaining a little bit about it.
First you think what is your purpose? Is it about drawing or Editing or photo making or else what? For your specific tusk you should deicide what is your need and choose your software. Oh-ho you don’t have a good idea about software? No problem In a few days will discuss about it.

Basic of Graphics –MS Paint -2nd Class.

Hey body! Hop you are enjoying. Ok let start the class. You see there are limitation for drawing, right? But for starting graphics you must keep practicing on paint. However you must use all the tools you have in left side of you paint software.

Basically use the “Pencil Tool, Line tool, Curve tool and other’s” you must try. Now, color your shape or draw or else and save the image or your work. Now close it and open again from your specific location. Try to modify see there are a limitation, ok don’t upset causes in after some class we see how to omit that kind of limitation.

Start with/Very basic of Graphics design.

Welcome to my 1st beginning dig. Simply be courage you can draw! I think you can hold or can move a mouse. If not no problem. You must can. Believe me. Ok, Let start.
This operation for those who use Windows Operating System (like 2000, XP, Vista etc).

Click in your desktop start button. Ok , there is a list- go to the “All Programs” and select “Accessories” then there is a pop-up menu select “Paint”. Very fine!

Now you can see there is a working area and some tools in left side.



Hold your left side mouse in working are and look! There are a line which is following your mouse. Un press your mouse, now you can click to “Eraser” tools beside your left corner. Come on the working are where were you draw something. Now press and hold the mouse and follow the line you draw. See, it is very easy.
Try again, try again and try again with other tools. Thank you.

The study of computer graphics.

Today, computers and computer-generated images touch many aspects of our daily life. Computer imagery is found on television, in newspapers, for example in their weather reports, or for example in all kinds of medical investigation and surgical procedures. A well-constructed graph can present complex statistics in a form that is easier to understand and interpret. In the media "such graphs are used to illustrate papers, reports, theses", and other presentation material.
The study of computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.
As an academic discipline, computer graphics studies the manipulation of visual and geometric information using computational techniques. It focuses on the mathematical and computational foundations of image generation and processing rather than purely aesthetic issues. Computer graphics is often differentiated from the field of visualization, although the two fields have many similarities.

Motion Design & digital compositing software packages
Since motion design is created using images and video sequences, a great complementary tool is a 3d software package. Cinema 4D is widely used for its intuitive interface, layered export to Adobe After Effects, and the additional MoGraph module, but there are also several others. Such packages can generate images or video sequences with an alpha channel, which stores all the transparency information.
Motion Design applications include:
• Adobe After Effects
• Jahshaka
• Autodesk Combustion
• Apple Motion/Shake
• Max/MSP
• Apple Quartz Composer
• Various VJ Programs
• Smith Micro Software Anime Studio
• Adobe Flash
3D Programs used in Motion Graphics include:
• Maxon Cinema 4D
• Softimage XSI
• Autodesk 3d studio max
• Autodesk Maya
• NewTek Lightwave
• e-on Vue Infinite
• The Blender Foundation Blender software
• EI Technology Group Electric Image Animation System
Motion Graphics Plugins include:
• Magic bullet (software)

Basic cocept of Graphics.

Today, computers and computer-generated images touch many aspects of our daily life. Computer imagery is found on television, in newspapers, for example in their weather reports, or for example in all kinds of medical investigation and surgical procedures. A well-constructed graph can present complex statistics in a form that is easier to understand and interpret.

History.
The advance in computer graphics was to come from one MIT student, Ivan Sutherland. In 1961 Sutherland created another computer drawing program called Sketchpad. Using a light pen, Sketchpad allowed one to draw simple shapes on the computer screen, save them and even recall them later. The light pen itself had a small photoelectric cell in its tip. This cell emitted an electronic pulse whenever it was placed in front of a computer screen and the screen's electron gun fired directly at it. By simply timing the electronic pulse with the current location of the electron gun, it was easy to pinpoint exactly where the pen was on the screen at any given moment. Once that was determined, the computer could then draw a cursor at that location.
