A. Multiple Choice Questions
1________ tool helps you to add a new layer to the image which is identical copy of the active layer.
(a) Smudge Tool
(b) Dodge Tool
(c) Perspective Tool
(d) Duplicate LayerShow solution
The Duplicate Layer option in GIMP creates a new layer that is an exact (identical) copy of the currently active layer. It is found in the Layers menu and is used when you want to work on a copy of a layer without disturbing the original.
2By default the mask is shown in ________, but you can change this if another mask colour is more convenient.
(a) Red
(b) Blue
(c) Green
(d) No colourShow solution
In GIMP, by default, the Quick Mask (layer mask) is displayed in red colour over the image. This red overlay indicates the masked (unselected) areas. The colour can be changed by double-clicking the Quick Mask button if another colour is more convenient for the user.
3In ________ mode, the selection is shown as a translucent screen overlying the image, whose transparency at each pixel indicates the degree to which that pixel is selected.
(a) Default
(b) Quickmask
(c) Marching ants
(d) NormalShow solution
In QuickMask mode, the selection is displayed as a translucent (semi-transparent) coloured overlay on the image. The transparency level at each pixel represents how much that pixel is selected — fully transparent means fully selected, and fully opaque (red) means not selected at all.
4________ are the transparent sheets one on top of the other.
(a) Masking
(b) Tools
(c) Layers
(d) None of the aboveShow solution
Layers in GIMP are like transparent sheets (similar to transparent acetate sheets) stacked one on top of another. Each layer can contain different parts of the image, and together they form the complete composite image.
5By default the extension of Gimp file is ________.
(a) .XCf
(b) .BMP
(c) .TIFF
(d) .PNGShow solution
The default native file format of GIMP is .XCF (eXperimental Computing Facility). This format preserves all GIMP-specific information such as layers, channels, paths, and guides. Other formats like .BMP, .TIFF, and .PNG are export formats.
6GPL stands for
(a) General Private license
(b) Great Pioneer License
(c) General Public Limited
(d) General Public LicenseShow solution
GPL stands for General Public License. It is a widely used free software license that guarantees end users the freedom to run, study, share, and modify the software. GIMP is distributed under the GNU General Public License.
7The image loses some of its quality by being ________.
(a) Scaled
(b) Merging
(c) Renaming
(d) MaskingShow solution
When an image is scaled (resized), especially when enlarged beyond its original dimensions, it loses some of its quality because GIMP has to interpolate (estimate) pixel values. This results in a loss of sharpness and detail, commonly known as pixelation or blurring.
8________ is a free and open-source image editing software.
(a) Adobe
(b) Gimp
(c) After Effects
(d) Paint Shop Pro X5Show solution
GIMP (GNU Image Manipulation Program) is a free and open-source raster graphics editor. It is available under the GNU General Public License. Adobe, After Effects, and Paint Shop Pro X5 are proprietary (paid) software.
9In ________ mode, over-application of the tool will produce noise.
(a) Sharpen
(b) Blur
(c) Dodge
(d) SmudgingShow solution
In Sharpen mode, the tool increases the contrast between adjacent pixels to make the image appear sharper. However, over-application of the Sharpen tool produces noise (unwanted random pixel variations) in the image, degrading its quality.
10________ takes colour in passing and uses it to mix it to the next colours it meets.
(a) Sharpen
(b) Blur
(c) Dodge
(d) SmudgingShow solution
The Smudge tool simulates the effect of dragging a finger through wet paint. It picks up (takes) the colour it encounters and mixes it with the colours it passes through next, creating a smeared or blended effect similar to smudging paint on a canvas.

In simple terms, GPL guarantees that the software will always remain free and open-source for everyone.
4Which tool is used to align the objects placed on different layers? Explain all its options.Show solution
The Align Tool in GIMP is used to align objects placed on different layers.
Options of the Align Tool:
1. Align Left Edge — Aligns the left edges of the selected layers/objects to the left edge of the reference (target).
2. Align Right Edge — Aligns the right edges of the selected layers/objects to the right edge of the reference.
3. Align Top Edge — Aligns the top edges of the selected layers/objects to the top edge of the reference.
4. Align Bottom Edge — Aligns the bottom edges of the selected layers/objects to the bottom edge of the reference.
5. Centre on Vertical Axis — Centres the selected layers/objects along the vertical axis of the reference.
6. Centre on Horizontal Axis — Centres the selected layers/objects along the horizontal axis of the reference.
7. Distribute Left Edges — Distributes the selected layers so that their left edges are equally spaced.
8. Distribute Right Edges — Distributes the selected layers so that their right edges are equally spaced.
9. Distribute Top Edges — Distributes the selected layers so that their top edges are equally spaced.
10. Distribute Bottom Edges — Distributes the selected layers so that their bottom edges are equally spaced.
11. Distribute Centres Evenly (Horizontal/Vertical) — Distributes the centres of selected layers evenly in horizontal or vertical direction.
Relative To: The alignment can be done relative to the First Item, Last Item, Largest Item, Smallest Item, Image, or Selection.
5Name the properties that need to be changed while scaling the image.Show solution
While scaling an image in GIMP, the following properties need to be changed:
1. Width — The horizontal dimension of the image in pixels (or other units like inches, cm).
2. Height — The vertical dimension of the image in pixels (or other units).
3. X Resolution — The horizontal resolution of the image (pixels per inch or pixels per cm).
4. Y Resolution — The vertical resolution of the image.
5. Interpolation Method — The method used to calculate new pixel values when the image is resized (e.g., None, Linear, Cubic, Sinc/Lanczos).
Note: When scaling, it is important to maintain the aspect ratio (the chain link icon between width and height) to avoid distorting the image.
6Which tool is used to lighten the pixels in an image?Show solution
The Dodge Tool is used to lighten the colour pixels in an image.
The Dodge tool selectively lightens the areas of the image where it is applied. It works by increasing the brightness of the pixels it is painted over. It is useful for highlighting specific areas of a photograph, such as brightening a face that appears too dark due to poor lighting.
Path to access: Toolbox → Dodge/Burn Tool (or press Shift+D)
7Which tool is used to darken the colour pixels in an image?Show solution
The Burn Tool is used to darken the colour pixels in an image.
The Burn tool selectively darkens the areas of the image where it is applied. It works by decreasing the brightness of the pixels it is painted over. It is useful for adding shadows or darkening overexposed areas of a photograph.
Note: In GIMP, the Dodge and Burn tools are combined into a single Dodge/Burn Tool. The mode can be switched between Dodge (lighten) and Burn (darken) in the Tool Options.
8Differentiate between Shear and Perspective tool.Show solution
| Shear Tool | Perspective Tool |
|---|---|
| The Shear tool shifts one part of an image, a layer, a selection, or a path to a particular direction while the other part is shifted in the opposite direction. | The Perspective tool allows you to change the perspective of the image by moving the four corner handles independently. |
| It creates a slanting/skewing effect in the image. | It creates a 3D depth effect, making the image appear as if viewed from a different angle. |
| Only horizontal or vertical shearing is possible. | All four corners can be moved freely to create any perspective. |
| It is used to create italic-like effects on text or objects. | It is used to correct perspective distortion in photographs or to create artistic effects. |
| The transformation matrix has one off-diagonal element changed. | The transformation involves a full projective (homographic) transformation. |
9What is the default background and foreground colour of image window?Show solution
In GIMP, the default colours in the image window are:
- Foreground Colour: Black — This is the colour used for drawing, painting, and filling operations.
- Background Colour: White — This is the colour used as the canvas background and for erasing (when the background layer is active).
These two colour boxes are visible at the bottom of the Toolbox. The foreground colour is shown in the upper-left box and the background colour in the lower-right box. You can reset them to the default black and white by pressing the D key.
10How is blur tool different from smudge tool?Show solution
| Blur Tool | Smudge Tool |
|---|---|
| The Blur tool reduces the contrast between adjacent pixels, making the image appear softer and less sharp. | The Smudge tool picks up the colour it encounters and mixes it with the colours it passes through, simulating the effect of dragging a finger through wet paint. |
| It averages the colour values of neighbouring pixels. | It does not average pixels; instead, it drags and smears colours along the direction of the stroke. |
| It is used to soften harsh edges or reduce noise in an image. | It is used to create a wet paint or blending effect in an image. |
| Over-application makes the image look blurry and out of focus. | Over-application makes the image look smeared and distorted. |
| It does not move colour from one place to another. | It physically moves colour from one location to another along the stroke path. |
11Name any four tools used for changing the pixel arrangement in an image.Show solution
The following four tools are used for changing the pixel arrangement in an image:
1. Scale Tool — Changes the size of the image or layer by resizing (scaling up or down), which rearranges the pixels.
2. Rotate Tool — Rotates the image or layer by a specified angle, changing the arrangement of pixels.
3. Shear Tool — Shifts pixels in one direction on one side and in the opposite direction on the other side, creating a slanting effect.
4. Perspective Tool — Rearranges pixels to simulate a change in the viewing angle, creating a 3D perspective effect.
Other tools that also change pixel arrangement include: Flip Tool, Smudge Tool, and Clone Tool.
12What is the difference between Blur tool and Sharpen tool?Show solution
| Blur Tool | Sharpen Tool |
|---|---|
| The Blur tool reduces the contrast between adjacent pixels, making the image appear softer. | The Sharpen tool increases the contrast between adjacent pixels, making the image appear crisper and more defined. |
| It is used to soften edges, reduce noise, or create a depth-of-field effect. | It is used to bring out details and make blurry images appear sharper. |
| Over-application makes the image look out of focus. | Over-application produces noise (unwanted random pixel variations) in the image. |
| It works by averaging the colour values of neighbouring pixels. | It works by enhancing the difference in colour values between neighbouring pixels. |
| Both tools are combined in the same Blur/Sharpen tool in GIMP, and the mode can be switched in Tool Options. | Same as above — mode is switched in Tool Options. |
13How is flipping an image different from rotating an image?Show solution
| Flipping an Image | Rotating an Image |
|---|---|
| Flipping creates a mirror image of the original image. | Rotating turns the image by a specified angle around a centre point. |
| It can be done horizontally (left-right mirror) or vertically (top-bottom mirror). | It can be done at any angle — 90°, 180°, 270°, or a custom angle. |
| The image is reflected across an axis (horizontal or vertical). | The image is turned around a pivot point. |
| Flipping does not change the angle of the image; it only reverses its direction. | Rotating changes the orientation/angle of the image. |
| Example: A photograph of a person facing right will face left after a horizontal flip. | Example: A landscape photograph will become a portrait after a 90° rotation. |
| Tool used: Flip Tool (Shift+F) | Tool used: Rotate Tool (Shift+R) |
14Write the steps to apply blend effect on an image.Show solution
The Blend Tool (also called the Gradient Tool) in GIMP is used to apply a gradient (blend) effect on an image.
Steps to apply blend effect on an image:
1. Open GIMP and open the image on which you want to apply the blend effect (File → Open).
2. Select the layer or create a new layer on which you want to apply the blend.
3. Click on the Blend Tool in the Toolbox (or press L on the keyboard).
4. In the Tool Options, select the desired Gradient (e.g., Foreground to Background, Foreground to Transparent, etc.).
5. Choose the Shape of the gradient — Linear, Radial, Angular, Conical, or Shaped.
6. Set the Blend Mode and Opacity as required.
7. Click and drag on the image canvas from the starting point to the ending point of the gradient. The direction and length of the drag determine the direction and spread of the blend.
8. Release the mouse button to apply the gradient blend effect.
9. Save the file using File → Export As in the desired format.
15What are Layers? What is the purpose of using Layers?Show solution
Layers:
Layers in GIMP are like transparent sheets (similar to transparent acetate sheets) stacked one on top of another. Each layer can contain different elements of the image — such as text, shapes, or photographs — and together they form the complete composite image. Layers are visible and manageable through the Layers Dialog (Windows → Dockable Dialogs → Layers).
Purpose of using Layers:
1. Non-destructive Editing — Each element is on a separate layer, so editing one layer does not affect the others. The original image remains safe.
2. Easy Compositing — Multiple images or elements can be combined on separate layers to create a composite image (e.g., collages).
3. Flexibility — Individual layers can be moved, resized, hidden, or deleted independently without affecting other layers.
4. Applying Effects Selectively — Filters and effects can be applied to individual layers without affecting the rest of the image.
5. Layer Blending — Different blend modes and opacity settings can be applied to layers to create artistic effects.
6. Text Handling — Text is placed on its own layer, making it easy to edit or reposition later.
7. Undo Capability — Working with layers makes it easier to undo changes to specific parts of the image.
16What is the need of merging the Layers?Show solution
Need of Merging Layers:
When working with multiple layers in GIMP, there are several reasons why merging layers becomes necessary:
1. Reduce File Size — A file with many layers is very large. Merging layers reduces the file size significantly.
2. Finalising the Image — Once the editing is complete and no further changes are needed to individual layers, merging them creates a single flat image ready for export.
3. Exporting to Other Formats — Many image formats (such as JPEG, PNG, BMP) do not support multiple layers. Merging layers is necessary before exporting to these formats.
4. Applying Global Effects — Some filters and effects need to be applied to the entire image as a whole. Merging layers first allows these effects to be applied uniformly.
5. Improving Performance — Working with too many layers can slow down GIMP. Merging layers that no longer need to be edited separately improves performance.
Types of Merging in GIMP:
- Merge Down — Merges the active layer with the layer directly below it.
- Flatten Image — Merges all layers into a single background layer.
- Merge Visible Layers — Merges only the visible layers.
C. Identify the Tools Used for the Following Purpose
1To resize the layer/imageShow solution
The Scale Tool is used to resize (scale up or scale down) a layer or the entire image. It changes the width and height of the image or layer while optionally maintaining the aspect ratio.
2To move layersShow solution
The Move Tool is used to move layers, selections, or paths within the GIMP canvas. It allows you to reposition a layer by clicking and dragging it to the desired location.
3To align the layers with various objectsShow solution
The Align Tool is used to align layers and objects with respect to each other or to the image canvas. It provides options to align left, right, top, bottom edges, and to centre objects horizontally or vertically.
4To create the mirror imageShow solution
The Flip Tool is used to create a mirror image of a layer or the entire image. It can flip the image horizontally (left-right mirror) or vertically (top-bottom mirror).
5To draw free hand drawingsShow solution
For freehand drawings, the Pencil Tool or Paintbrush Tool is used to draw freely on the canvas. The Free Select Tool (Lasso Tool) (Shortcut: F) is used to make freehand selections by drawing an irregular outline around an area.
6To lighten the colour pixels of an imageShow solution
The Dodge Tool is used to selectively lighten the colour pixels of an image. When applied to an area, it increases the brightness of the pixels in that region.
7To give wet paint effect in an imageShow solution
The Smudge Tool is used to give a wet paint effect in an image. It simulates the effect of dragging a finger through wet paint by picking up colour and mixing it with the colours it passes through.
8To shift one part of an image/a layer to a particular directionShow solution
The Shear Tool is used to shift one part of an image or a layer in a particular direction while the opposite part shifts in the opposite direction, creating a slanting/skewing effect.
9To apply different colours without affecting the original imageShow solution
The Quick Mask or Layer Mask is used to apply colours and effects to specific areas without affecting the original image. Alternatively, working on a New Layer above the original allows colour changes without modifying the original layer.
10To remove objects from the canvasShow solution
The Eraser Tool is used to remove (erase) objects or parts of a layer from the canvas. On a layer with transparency, it erases pixels to make them transparent. On the background layer, it replaces pixels with the background colour.
