Unit 1 Selby High School Fireworks

Vector imagesWhat are vector images? How are

they different from bitmap images?


Objectives• To understand what a vector image is• To understand how to create vector

images using fireworks


Vector images• Are made up of lines and curves. • When you make them bigger or

smaller they don’t lose their quality• They are not as detailed as bitmap

images, but they take up less computer memory


Fireworks IntroductionDraw a Vector Bike


Create New document & Find your picture…

Go to www.google.co.uk and find a picture

and use the settings as below.


Main Frame…

Ctrl Z pressed at the same time will

undo the last step – TRY IT NOW.

Click on the centre of the rear wheel, move your

mouse then click where you want the line to be drawn. Use this method to draw

the main bike frame. Double click to complete

the drawing.


Front Forks…Draw the front

forks of your bike. The pen tool is really useful for drawing straight

lines.


Saddle StemDraw another line from the saddle to the chain sprocket.


Handle bars… Add the handlebars, again with only straight

lines.


Wheels… Click on the ellipse tool. Hold shift and

drag to draw a circle roughly the

shape of your front wheel.


Finish the front wheel…Change the size of

your front wheel so that it fits nicely over your base

picture. Remember to keep the width

and height the same to keep it a

circle. Then nudge it into position.


Rear wheel…Copy and paste

your front wheel and position it on

the rear wheel


Chain Sprocket…Reduce the size of the pen tool and draw a smaller

circle and nudge it into place on the chain sprocket.


Pedals…Draw in the pedals

and the pedal spindle.


Saddle…Zoom in and go to the saddle part of your bike. Use the rectangle tool and draw a rectangle over the top of

your saddle.


Distort…1. Use the distort

tool and drag the bottom left corner upwards

to create a wedge shape.


SAVE your work then delete your internet picture…

Now that your bike is complete, you can delete your original picture.

Find the original on the layers tab on

the right and click the trash can to

delete it.


Errors… If there are any errors or gaps

between your lines, you can see them

now. You can modify your bike

now so that it looks complete. You’re

done!

changing some colours
