Adobe Photoshop is a software editor specialized in image processing in terms of the multiplicity of its potential ... And it contains many tools that make photo editing fast and easy with precision ..

The main purpose of the work on this program is a modification, change and liberalization in the pictures, whether it be through changes in color, correct or add some effects that serve up your images so that the best results of the image that the amendment to it.

There are two different types of graphics, and Understanding the basic principles of these two types is necessary to deal with both of them, because the difference between the object is not just a qualitative difference, as the special skills of each program, Vahdahma works his tools to create the drawing .. And the other is working on adding some effects and coloring the pictures, for example, if we need to redraw the logo (logo), the programs coloring Bitmap graphics here do not do the job perfectly, but drawing programs Vector graphics perform that task smoothly and easily ..

If we had a picture, and we want to change some colors, or modify some of its parts, or change the background, or give some aesthetic effects are not met by drawing programs Vector graphics for this purpose in the same coloring efficiency programs Bitmap graphics.





The former examples: clear to us the importance of these two types of graphics programs, and how they relate together, we can not be working in the field of designs without the need for programs to coloring and drawing Bitmap graphics Vector graphics together, and participate in these types of programs being the two-dimensional ..

Bitmap graphics programs coloring



Is technically called a rectangular image, and used a range of colors, known as points of television pixels, and each point is the TV pixels designed for a particular site, and the value of a color.

As these programs allow us to make some changes in the image example: the elements of any image, for example, is a formal vocabulary to add to associating different colors, add lighting to it, Alazlam, the shade varying degrees and different angles.

When using programs coloring Bitmap graphics and the realization of its vocabulary to add some special effects, whether in some detail, or in general, because they show grades acceptable to the colors and shadows and is a restricted, because they contain a fixed number of points television, and as a result may miss these data the degree of If clarity appeared on the screen or when printed, and have low visibility from the level set for it.





Vector graphics drawing programs
And form vector graphics Vector graphics of lines and curves defined in a way forms computational e are called vectors, and describe the vector image and according to the figures of engineering, graphics and vector with the independence of clarity, it can be shown to any size and printed in any degree of purity without loss of data and clarity.



As a result, is a vector graphics Vector graphics the best choice for graphics that retain good in zigzag lines when viewed in different sizes such as used in the application of the logo. In all cases can be printed or displayed with any degree of clarity, without loss of detail.

It also allows us to these programs are free to determine the size of the drawing or decreased after the completion of it without affecting the general form or on the degree of precision, but we can not do this in the programs of coloring Bitmap graphics because in the case of full size image grows with the size of points pixels and become features of the image is not clear.
