Vector Graphics: Unit Exam A
Bitmap and vector images, fills, strokes, nodes and groups, what makes a good logo, and mood boards.
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.
- LB A grid of pixels
A bitmap stores the colour of every pixel in a grid.
Tick one box.
- LA Shapes, lines and curves stored as instructions
A vector image stores shapes as paths and points, not pixels.
| Bitmap | Vector | |
|---|---|---|
| A photograph taken on a phone | ||
| A logo that must print on a pen and on the side of a bus | ||
| Goes blocky when it is enlarged a lot | ||
| Can be resized without losing quality |
Tick one box in each row.
- LA photograph taken on a phone: Bitmap
- LA logo that must print on a pen and on the side of a bus: Vector
- LGoes blocky when it is enlarged a lot: Bitmap
- LCan be resized without losing quality: Vector
Photos are bitmaps and go blocky when enlarged. Logos are vectors because they scale to any size without losing quality.
Tick one box.
- LD It can be made bigger or smaller without losing quality
Vector graphics are scalable: they are redrawn sharply at any size.
- Lstroke
The outline is the stroke. Its colour and width can be changed.
- Lfill
The colour inside is the fill.
Tick one box.
- LC A point on a path that can be moved to change the shape
Moving a node, or its curve handles, reshapes the path.
Tick one box.
- LB So they can be moved and resized as one object
A group behaves like one object.
- LSimple and clear, so it is recognisable and memorable
- LWorks at any size and in one colour, and its colours or images suit the business
A good logo is simple, so it is recognisable at a glance and easy to remember, and it works at any size and in one colour. Its colours and images should suit a bakery, such as warm colours and a loaf or a whisk.
Tick one box.
- LD A collection of images, colours and fonts that plans the look and feel of a design
A mood board gathers ideas for the style before designing starts.
Tick one box.
- LC SVG
SVG stands for scalable vector graphics.
- LA vector stores shapes as instructions or coordinates, not every pixel
- LA bitmap stores data for every pixel, and a large image has a great many pixels
A vector file only stores the instructions for each shape, such as a circle's centre, radius and colours. A bitmap stores a colour for every pixel, and a large image has millions of them, so its file is far bigger.
| Fill | Stroke | Group | |
|---|---|---|---|
| Make the inside of a circle red | |||
| Give a square a thick blue outline | |||
| Keep a house's walls and roof together when moving it |
Tick one box in each row.
- LMake the inside of a circle red: Fill
- LGive a square a thick blue outline: Stroke
- LKeep a house's walls and roof together when moving it: Group
Fill colours the inside, stroke sets the outline, and group joins shapes into one object.
Tick one box.
- LA You can see the individual square pixels
Enlarged pixels show as blocks: the image is pixelated.
Tick one box.
- LC Bring the circle forward in the layer order
The order of objects decides which appears in front.
- L200
20 x 10 = 200 pixels.
- LTo collect ideas and inspiration for colours, fonts and images
- LTo agree the look with the client before work starts, which saves time redesigning
A mood board collects ideas for colours, fonts and images in one place, so the designer and the client can agree the look and feel before any real work starts, which saves time redesigning later.
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.
