Before you begin
- Check whether your route is AS Level (Topics 1–11) or full A Level (Topics 1–21).
Work on paper. Try each question before revealing help, and explain why your method works.

Before Topic 19: graphics creation
What you will learn
- Apply shared graphics tools: selection, layers/order, alignment, grids/guides, colour picker, crop, RGB/HSL/CMYK/CMS, resolution, fills and export
- Create/edit vectors with shapes, Bezier curves, transforms, nodes, paths, trace and bitmap conversion
- Create/edit bitmaps with selection/masking, colour, brushes, clone/erase/blur/sharpen and canvas/resolution changes
- Compare vector/bitmap, file formats and lossy/lossless compression for screen and print
Choose the right representation and colour model
Vector graphics store shapes and paths, so they scale cleanly and suit logos, icons and diagrams. Bitmap graphics store pixels and suit photographs and textured images, but can pixelate when enlarged. RGB is additive light for screens; CMYK is subtractive ink for print. HSL represents hue, saturation and lightness; colour-management systems help keep colour consistent across devices. Resolution must match output size and viewing distance.
Use tools deliberately and preserve the source
Selection, layers/order, alignment and distribution help control layout; grids, guides and snapping support precision. Vector work uses shapes, Bezier curves, nodes, handles, transforms and paths. Bitmap work uses selections, masks, crop, retouch, colour and filters. Export formats serve different needs: SVG remains vector; PNG supports lossless images/transparency; JPEG is lossy for photos; GIF has limited colour/animation; BMP/TIF/PDF suit other workflows. Choose format, dimensions, resolution and compression together.

Pause and explain
Which approach best demonstrates secure, reliable IT practice in graphics creation?
Worked example
A logo must appear on a small website icon and a large printed banner. Recommend a source format and exports.
Show the worked solution
- Create the master as a vector with editable paths.
- Export an SVG for web and a print-ready PDF or suitable raster at final dimensions.
- Check colour conversion, resolution, transparency and legibility at each size.
Answer Keep an editable vector master so the logo scales without pixelation. Export SVG for supported web use and a print-ready PDF or high-resolution raster in the printer's required colour space. Check fine details at icon size, colour appearance in CMYK and output dimensions. A low-resolution bitmap enlarged for the banner may become visibly pixelated.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A printed photograph appears blocky. Explain what resolution change may help and what cannot be recovered.
Give me a hint
Differentiate resampling dimensions from missing source detail.
Compare my reasoning
- Check pixel dimensions at the intended physical print size.
- Return to a higher-resolution source if available.
- Avoid claiming interpolation recreates captured detail.
Use a higher-resolution original or reduce the physical print size so pixel density is adequate. Increasing pixel dimensions by interpolation may smooth edges but cannot restore detail that the original did not capture. Check the printer's required resolution and view at the intended distance.
Look for these in your work
- Relates pixels to output size
- Prefers a suitable source
- States interpolation limits
A designer needs a transparent product image for web and a photographic background. Which format is suitable and why?
Give me a hint
Consider transparency, photographic detail, file size and quality loss.
Compare my reasoning
- Use PNG when transparency and clean edges matter.
- Use JPEG for a photographic background without transparency.
- Check export quality and dimensions for the target display.
PNG is suitable for the product cut-out because it supports transparency and lossless edges. JPEG is suitable for a photographic background where smaller size is useful and transparency is not needed, but it uses lossy compression. Keep an editable source and compare the exports at the actual web size.
Look for these in your work
- Matches formats to properties
- Explains compression
- Checks actual-size output
A traced vector from a low-resolution logo has hundreds of jagged nodes. What editing steps could improve it?
Give me a hint
Simplify paths and rebuild important curves rather than preserving every pixel edge.
Compare my reasoning
- Remove redundant nodes while preserving key shape points.
- Use smooth/cusp nodes and Bezier handles appropriately.
- Compare the cleaned vector against the source at multiple sizes.
Simplify each path by removing redundant nodes, keep nodes at meaningful corners, and use smooth nodes with Bezier handles for curves while retaining cusp nodes for sharp corners. Rebuild small details if tracing created noise. Compare at icon and print sizes; an automatic trace may invent shapes from low-resolution pixels and still require manual correction.
Look for these in your work
- Uses node/path editing
- Distinguishes smooth and sharp points
- Validates at target sizes
Common mistakes
- Assuming changing pixel dimensions creates real detail
- Using RGB values as print-proof CMYK colour
- Converting a bitmap to vector without checking path quality
What can you explain now?
A printed photograph appears blocky. Explain what resolution change may help and what cannot be recovered.
Compare with the explanation
Use a higher-resolution original or reduce the physical print size so pixel density is adequate. Increasing pixel dimensions by interpolation may smooth edges but cannot restore detail that the original did not capture. Check the printer's required resolution and view at the intended distance.
Differentiate resampling dimensions from missing source detail.

Why is vector usually suitable for a logo but bitmap for a photograph?
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
