4 To open (with Windows open): Start Click on Start Point to Programs Point to Accessories Click on Paint Pictures are made up of many small dots ( pixels ) and are known as bitmaps Lines and letters are jagged especially if there are any enlargements You can t usually make changes to objects and text that you have included You can draw straight lines, but not change them once they re drawn (apart from rubbing them out and drawing them again) You can draw rectangles and ovals; their line width and colour must be set before drawing, but the fill can be changed later Can t be opened on its own (included within Microsoft Office programs eg Word) Click on the Drawing icon in the toolbar at the top Mathematical formulas ( vectors ) are used to draw lines between points Lines and letters are smooth even when enlarged It s usually very easy to make changesto objects and text that you have included You can draw straight lines, and change their length, direction, position, width, colour, and style later You can draw rectangles and ovals; their line width and colour, and fill colour, can be changed later

5 No further shapes are available Objects with a number of straight sides may be drawn; but points and lines can t be changed later Parts of drawings can be rubbed out with a rubber All parts of a drawing are at the same level, and are replaced by drawings made over them Parts of a drawing can be selected inside a frame Text can be edited when it is entered, but not later A large number of further shapes (Auto Shapes) is available Objects with a number of straight or curved sides may be drawn; points and lines may be changed later Objects can be deleted using the Delete key; (there is no rubber ) Each object which is drawn is at a different level; the order may be changed by sending back or bringing forward Objects can be selected, either separately (by clicking on them) or inside a frame Text (in Text Boxes) can be edited later as in a word processor (change font, size, attributes, justification, etc)

6 All the parts within the selection frame are included when a part of a drawing is selected Only objects which are completely within the selection frame are included when a part of a drawing is selected Selected parts (including text) may be enlarged, reduced, stretched, moved, rotated (90, 180, or 270 ), flipped (horizontally, vertically), and skewed All selected parts are a group Changes to a selected part apply only to that part A part of a drawing mov-ed or pasted into another part of the drawing covers the part where it is placed; the covered part is replaced and no longer exists Selected objects may be moved; all except text may be enlarged, reduced, rotated (any angle), stretched, and flipped (horizontally, vertically) Selected objects can be grouped Properties of all selected objects or a group can be changed at once Selected parts of a drawing can be deleted, or copied or cut then pasted, into another part of the drawing, or into the same or another file which is open A part moved or pasted into another part of the drawing covers the part where it is placed; however, the covered parts still exist and can be changed later

7 Changes can be undone by clicking on Undo (or pressing Ctrl+Z); can undo the last three changes Drawings can be saved as files (formats include BMP, JPEG, GIF, PNG, TIFF) Saving Bitmap drawings requires a large amount of memory the bitmap drawing of battery and bulb was saved as a *.jpg file (43KB), *gif (7KB), *.bmp (126KB), and *.tif (128KB) and the sizes of the files vary according to the size of the picture Changes can be undone by clicking on Undo (or pressing Ctrl+Z); can undo the previous 100 changes Drawings cannot be saved as files but can be copied and pasted into other programs Draw (vector) drawings require a much smaller amount of memory when saved; the vector drawing was saved as *.wmf (Windows Metafile) only 5KB, irrespective of the size of the drawing 1 Bulb 1 Piece of Wire 1 Battery

8 Bitmap drawing files have information about each of the very large number of small separate dots on the screen Bitmap drawings (especially JPEG and GIF) can be included in pages in the Internet Vector drawing files are largely mathematical formulas of the positions of points and lines on the screen Vector files cannot be placed directly in Internet pages; they can by: copying pasting into bitmap programs then saving as JPEG or GIF) or by saving in a PDF (Acrobat) file
