Painting and Drawing

While we talk about graphics, we mean pictures can be either photographs or illustrations. If you want to acquire graphics into a Web page or multimedia representation, you either have to generate them in several kind of graphics application through drawing or painting them right there in the application or bringing them in the application through a digital scanner or camera and then editing and saving them in a form appropriate to your medium.

Several  software  applications  propose  a  variety  of  features  for  editing and  creating  pictures on the computer. Still multimedia authoring and word processing programs comprise several simple traits for drawing on the computer.

Consequently, painting and drawing application in computer graphics permits the user to pick and edit any type of object at any time. The basic dissimilarity is as follows:

Drawing in a software application, means utilizing tools which create "objects," as squares, circles, text or lines that the program treats as discrete units. If you sketch a square in PowerPoint, for illustration, you can click anywhere on the square and move this around or resize this. This is an object, as like typing the letter "e" in a word processor. That is a drawing program permits a user to position standard shape i.e. also termed as symbols, templates or objects that can be edited through rotations, translation and scaling operations on these shapes.

Painting functions, conversely, don't create objects. If you seem a computer screen, you will see that it's made up of millions of minute dots termed as pixels. You will see similar thing in an easier form if you seem the colour comics in the Sunday newspaper: many dots of various colour ink which form a picture. Not like a drawing function, a paint function changes the colour of particular pixels based upon the tools you selected. In a photograph of a person's face, for illustration, the colours change slowly due to light, shadow and complexion. You require a paint function to make this kind of consequence; there's nothing that you can choose or move the way you can along with the drawn square that is, a painting program permits the user to paint arbitrary swaths utilizing brushes of different sizes, shapes, colour and pattern. More painting program allows placement of such pre-explained shapes as rectangles, canvas and polygon. Any one part of the canvas can be edited at pixel level.

The motive why the dissimilarities are significant is that, as noted previous, lots of various kinds of programs offer various kinds of graphics features at various levels of sophistication, but they tend to specialize in one or another. For illustration:

1)   Many word processors, similar to Word, give a handful of easy drawing functions.

They are not powerful, although if all you require is a basic demonstration made up of simple shapes to clarify a point, they are fine.

2) Several programs specialize in graphics creation. Some of these are all-purpose programs, like KidPix, that offers both drawing and painting functions. KidPix is targeted particularly at children; this has a simplified interface and needs the sophisticated functions a professional artist may want.

The other programs, like Adobe PhotoShop, specialize in painting functions, even if they may comprise drawing functions also. Painter is a paint-oriented program which offers highly sophisticated, "natural media" functions that estimated the outcomes of water-colours or drawing along with charcoal on textured paper.

Another graphics programs, as Adobe Illustrator, specialize in drawing for professional designers and artists; AutoCAD is utilized mainly for engineering and technical drawing.

3) Page layout, representation, multimedia authoring and Web development programs generally include a variety of graphics functions ranging from the easy to the difficult, although their major reasons is composition, not image editing or creation.

It is, they permit you to import or create text and graphics and sound, perhaps, animation and video.

Mostly of the graphics characteristics in these categories of programs are restricted to drawing functions since they suppose that you will do more complicated work in a program dedicated to the other functions for instant: editing photos in a paint program and writing in a word processor, then import your work to arrange the various pieces in the composition program. Some multimedia authoring systems, conversely, also offer drawing and painting functions.

Through the way, the dissimilarities in composition programs are mostly in the form of their output: Page layout programs, like PageMaker and QuarkXPress, are for composing printed pages; multimedia authoring programs and presentation, as PowerPoint and HyperStudio, are for slide presentation and computer displays; and Web-development applications, as Netscape Composer all are for well Web-pages.

4) What  whether  you  are  going  to  create  a  magazine,  book  ,  newspaper or  maybe  a multipage list of options for a restaurant.   Then we require a page layout program. The well famous softwares in page layout are as:

a.      Quark Express

b.      Page Maker (Adobe)

c.       Indesign (Adobe)

d.      Publisher (Microsoft)

The Queen of Page Layout is Quark Express, owned through Quark Express and Indesign is the King owned through Adobe and at last there is Microsoft Publisher that is very simple to utilize.

5) To create posters, business cards, brochures, stationary, cereal boxes, coffee mug design, candy wrappers, half gallon jugs of orange juice, cups or something else you see in print, most designers are going to utilize vectorised programs to produce these things come to life. Vectors are wonderful since they print very well, and you can scale them up to create them large, or scale them down to create them tiny, without distortion. Adobe Illustrator is the King of Vector Programs, hands down.  Within Adobe Illustrator, you can make a 12 foot, through 12 foot document. If we are going to create anything i.e. going to be printed, we are doing it in Illustrator. Something that you make in Illustrator and the text you utilize will come out great. The thing is Illustrator is tough to learn. This is not an intuitive program at all. This is since vectors utilize control points termed as paths and anchor points. To anyone new, they are tough to understand, determine and control. That is the other story. If you are creating a poster, you would create your logo, artwork and text in Illustrator. You would manipulate your images even in Photoshop and after that, "place" them to the Illustrator.
