Basic Skills in Photoshop CS6 – Part 2

Using Drawing Tools to Create Lines

You can create straight lines in Photoshop in several ways.

Solution

Vertical and Horizontal Lines

Using the Brush or Pencil Tool (B), move the cursor to the position from which you’d like the line to start on your document. Click and hold down the mouse button.

Hold down the Shift key to constrain mouse movement to straight lines, then drag the cursor to draw your line. Release the mouse button to complete the line.

Diagonal Lines

Using the Brush or Pencil Tool (B), position the cursor at the point from which you’d like the line to start and click once (releasing the mouse button this time). Hold down Shift and click on the spot where you’d like your line to end. Photoshop will connect the dots with a straight line.

Vector Lines

If you want to make vector lines, use the Line Tool (U), position your cursor , then click and drag. Hold down the Shift key if you want to constrain mouse movement to vertical, horizontal, or 45-degree lines. You can modify the color , stroke, and weight of the line in the options bar.

Basic Skills in Photoshop CS6-Part2Vector Shapes Preferable

In today’ s environment of devices with different resolutions, you’re better off using vector shapes whenever possible. Vector shapes, unlike raster layers, can be resized bigger or smaller without losing graphic information. If you need to make a version of a graphic at 96ppi and another version at 72ppi, a vector graphic will allow you to make that change without any problem, whereas you’re likely to face more loss of quality with a raster-based image.

Resizing a Document

Sometimes, you need to use images that were created by another person, or perhaps designed with another project in mind. In such cases, you may have to resize an an existing document.

Solution

Bring up the Image Size dialog box by selecting Image > Image Size or pressing Command-Option-I (Ctrl-Alt-I on Windows). You can resize the document by altering either the Pixel Dimensions or the Document Size. Use the former when resizing images that will be used on screen (such as on a web page), and the latter for resizing images that will be printed. You can maintain the original document proportions as you resize the image by checking the Constrain Proportions checkbox. T o scale layer styles (drop shadows, strokes, and so on), check the Scale Styles checkbox.

Resizing a Layer or Selection

Photoshop lets you resize layers or portions without affecting the overall size of a document.

Solution

From the Layers panel, select the layer that contains the element you wish to resize. If it contains other elements that you wish to exclude, select your element using one of the selection tools.

After making your selection, use Edit > Free Transform or press Command-T (Ctrl-T on Windows). A bounding box with handles will appear around your selection. Click and drag these handles to resize the element, as shown in Figure 2.7. T o keep the transformation in proportion so that the image avoids appearing squashed or stretched, hold down the Shift key and resize it using the corner handles.

3D Faces

3DFACE creates a three or four sided surface anywhere in 3D space. You can specify different Z coordinates for each corner point of a 3D face. 3DFACE differs from SOLID, which creates a three- or four-sided surface that is parallel to the current UCS and can be extruded.

1.    Begin     a new drawing.

2.  Set    the visual style to Conceptual.

Finding, inserting, and storing drawing content

The Scrapbookdocker lets you use clipart, photo images, and sounds stored on the Corel content CDs or that are available online. The digital content manual contains pictures of the graphics available on the CD and lists their folder locations.

You can browse for clipart, photo images, and sound files on your system, or browse online on Corel on the Web; or you can search for content by using keywords. You can also create your own scrapbook to store content from the drawing window that you want to reuse.

To browse for clipart, photos, and sound files

1   Click Window ` Dockers ` Scrapbook.

2   Insert a Corel content CD into the CD drive.

3   Double-click an icon in the CD list and navigate to a folder.

About vector graphics and bitmaps

The two main types of computer graphics are vector graphics and bitmaps. Vector graphics are made of lines and curves, and they are generated from mathematical descriptions that determine the position, length, and direction in which lines are drawn. Bitmaps, also known as raster images, are composed of tiny squares called pixels; each pixel is mapped  to a location in an image and has numerical color values.

 Vector graphics are ideal for logos and illustrations because they are resolution- independent and can be scaled to any size, or printed and displayed at any resolution, without losing detail and quality. In addition, you can produce sharp and crisp outlines with vector graphics.

 Bitmaps are excellent for photographs and digital paintings because they reproduce color gradations well. Bitmaps are resolution-dependent — that is, they represent a fixed number of pixels. While they look good at their actual size, they can appear jagged or lose image quality when scaled, or when displayed or printed at a resolution higher than their original resolution.

You can create vector graphics in CorelDRAW. You can also import bitmaps (such as JPEG and TIFF files) in CorelDRAW and integrate them into your drawings. For information about working with bitmaps, see “Working with bitmaps” on page 207.
