Vector Graphics: Unit Exam B
Choosing bitmap or vector, paths and nodes, tools for duplicating, aligning and grouping, and planning a design.
Instructions
- Time allowed
- 25 minutes
- Total marks
- 25
- Calculator
- No calculator is permitted.
- Answer all the questions.
- The number of marks for each question is shown in brackets. Use it as a guide to how much to write.
- The clock at the top counts down from the real time allowed. When it reaches zero the paper is locked and marked, as it would be collected in the exam hall.
- Read every question to the end before answering. Where a question says tick two boxes, tick exactly two: ticking more than asked scores nothing. Type one word and number answers carefully, because they are marked exactly.
Questions
Answer every question, then finish the paper to have it marked. Marking as you go teaches you far less.
Tick one box.
- LA Vector
A vector stays sharp at any size.
| Bitmap | Vector | |
|---|---|---|
| Stored as a grid of coloured dots | ||
| Stores shapes as paths with nodes | ||
| Best for a detailed photograph | ||
| Edges stay sharp at any size |
Tick one box in each row.
- LStored as a grid of coloured dots: Bitmap
- LStores shapes as paths with nodes: Vector
- LBest for a detailed photograph: Bitmap
- LEdges stay sharp at any size: Vector
Bitmaps are grids of pixels and suit photographs. Vectors are paths and stay sharp when scaled.
- Lpixelated
It is pixelated: each pixel has become a visible square.
Tick one box.
- LC A line made of nodes joined by straight lines or curves
A path runs through nodes, joined by straight or curved segments.
Tick one box.
- LD Changing the fill colour
The fill colour changes how it looks, not its shape.
| Group | Duplicate | Align | |
|---|---|---|---|
| Make an exact copy of a star | |||
| Line up three shapes along their top edges | |||
| Join shapes so they move together |
Tick one box in each row.
- LMake an exact copy of a star: Duplicate
- LLine up three shapes along their top edges: Align
- LJoin shapes so they move together: Group
Duplicate copies, align lines objects up, and group joins them into one object.
- LIt can be scaled to any size, from a business card to a billboard, without losing quality
- LThe file is small, and the shapes and colours are easy to edit
A vector logo can be scaled to any size, from a business card to a billboard, and stays sharp. The file is also small, and its colours and shapes can easily be edited later.
Tick one box.
- LB How thick the outline of a shape is
Stroke width sets the thickness of the outline.
Tick one box.
- LD Ellipse or circle tool
The ellipse tool draws circles and ovals.
- L5000
100 x 50 = 5000 pixels.
| True | False | |
|---|---|---|
| Enlarging a vector image makes it blurry | ||
| A vector image stores the colour of every pixel | ||
| SVG is a vector file format | ||
| Bitmaps are good for photographs |
Tick one box in each row.
- LEnlarging a vector image makes it blurry: False
- LA vector image stores the colour of every pixel: False
- LSVG is a vector file format: True
- LBitmaps are good for photographs: True
Vectors stay sharp and do not store pixels. SVG is a vector format, and bitmaps suit photographs.
- LDraw a rectangle for the walls with the rectangle tool
- LDraw a triangle for the roof, with the polygon or pen tool
- LSet the fills and strokes, then align and group the shapes
Draw a rectangle for the walls with the rectangle tool and a triangle for the roof with the polygon or pen tool. Give each a fill and a stroke, add smaller rectangles for the door and windows, then align the shapes and group them so the house moves as one.
- LA collection of images, colours, fonts and textures showing the intended look and feel
- LIt gives ideas and lets the designer agree the style with the client before starting
A mood board is a collection of images, colours, fonts and textures that shows the look and feel a design is aiming for. It gives the designer ideas and lets them agree the style with the client before they start, so less work is wasted.
This is an original Key Stage 3 assessment. Most questions are closed, so the marking is exact, and the written answers are marked against a mark scheme in the same style as a GCSE paper, so the format is familiar long before it counts.
