This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will design graphics using vector graphic editing software. They will apply their skills by creating an illustration, a logo, and icons. Pupils will recognise that objects and be grouped and combined to create new elements and that vector drawings are made up of paths.
Lesson Summary
You will learn to compare vector and bitmap images and consider which image type best suits which situation.
Key Notes
- Vector images are made from shapes and paths so they stay sharp when resized.
- This makes them good for logos or icons which need to be presented in different sizes.
- Bitmap images are made from pixels. They can lose quality when resized and are better for photos and detailed pictures.
Vocabulary To Learn
- bitmap: images that are made from pixels
- pixel: a single element of an image on a computer screen
Common Mistakes To Avoid
- Vector images are better than bitmap images in every situation.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Vector images are made from shapes and paths so they stay sharp when resized. This makes them good for logos or icons which need to be presented in different sizes.
2. Define this computing term and give one practical example. 'bitmap'
images that are made from pixels. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Vector images are better than bitmap images in every situation. Correction: Vector and bitmap images are suited to different tasks. Vectors are best for simple, scalable designs like logos, while bitmaps are better for detailed images like photos.
