Frequently asked questions from CBSE(NCERT) Grade 7 INFORMATION TECHNOLOGY — Chapter-5 Digital Image Editing & Graphics, with answers and explanations. These are sample questions; the exam has its own separate question set.

What is a layer in digital image editing?

A. A transparent sheet that holds image content and can be edited independently ✓
B. A permanent part of the image that cannot be moved
C. A filter applied to the entire image at once
D. A tool used only for drawing shapes

Answer: A. A transparent sheet that holds image content and can be edited independently
Layers are fundamental in image editing, allowing independent manipulation of different image elements while maintaining flexibility.

Which tool is used to select a specific area of an image for editing?

A. Gradient tool
B. Selection tool ✓
C. Filter tool
D. Canvas tool

Answer: B. Selection tool
Selection tools (like rectangle select, lasso select) allow users to isolate specific portions of an image for targeted editing.

In image editing software, what happens when you decrease the opacity of a layer to 50%?

A. The layer becomes half as large
B. The layer becomes half transparent, allowing layers below to show through ✓
C. The layer becomes twice as bright
D. The layer is permanently deleted

Answer: B. The layer becomes half transparent, allowing layers below to show through
Opacity at 50% makes the layer semi-transparent, blending it with whatever is beneath it in the layer stack.

What is the relationship between layers, opacity, and blending in image editing?

A. They are completely independent and unrelated concepts
B. Opacity and blending modes work together on layers to control how layers interact with content below ✓
C. Opacity only affects the canvas, not individual layers
D. Layers have no effect on how opacity works

Answer: B. Opacity and blending modes work together on layers to control how layers interact with content below
Opacity controls transparency level, while blending modes determine how a layer combines with layers beneath it, working together for layer composition.

A designer applies a blur filter to a text layer at 80% opacity. What might be an unexpected result and why?

A. The text becomes completely invisible due to the filter
B. The blur effect is applied before opacity, making the text slightly blurry but still readable
C. The text becomes more opaque instead of the intended transparency
D. The blur filter only works on image layers, not text layers ✓

Answer: D. The blur filter only works on image layers, not text layers
Most image editing software requires rasterizing (converting) text layers before applying filters, as filters work on pixel-based content, not vector text.
