5. What are Dockable Dialogues in GIMP? [CBSE Handbook]
Ans. A “dock” is a container window that enfold collection of the Tool Options dialog, Brushes dialog, Palette dialog, etc. GIMP
has only two default docks:
• The Layers, Channels and Paths dock.
• The Brushes, Patterns and Gradients dock.
Each window has its own tab in these docks.
6. What is the native graphic file format for Gimp?
Ans. GIMP’s “native” format is XCF. This will ensure that an image’s details, including its layers, are preserved.
B. Long answer type questions:
1. What is the purpose of Scale image in GIMP? [CBSE Handbook]
Ans. By altering the quantity of pixels in an image, the Scale Image command can physically increase or decrease the size of the
image. It resizes the canvas in accordance with the size change in the image’s contents.
It affects the entire picture. Since a layer cannot be less than one pixel width or height, if your image comprises layers that
are different sizes, shrinking the image smaller could cause some of them to disappear entirely. Before the procedure is
done, you will be informed if this occurs.
2. Explain the concept of layers in GIMP.
Ans. The image is split up into layers. Layers allow us to build an image with multiple conceptual components. The use of layers
allows for the manipulation of one aspect of the image without impacting the other. The background of the picture is on
the bottom layer. It can either be transparent or filled with the backdrop or foreground colour. It is surrounded by every
element of the image. A layer could be visible or concealed. All the layers can later be combined to create the image as
needed. The number of layers is not constrained.
3. What are filters? Give examples of filters in GIMP.
Ans. In the GIMP software, filters are pre-designed effects with customizable data that aid in image alteration and picture
editing tasks. You can use filters on an image, geometric shapes, or text. Gimp contains a number of filters that may be
used for a variety of tasks and have a variety of effects. For example: distort, lightening effects, etc.
4. What are channels in GIMP?
Ans. Although layers and channels are fairly similar, each layer in an image’s colour model corresponds to a different level
(RGB, HSV or CMYK). Channels can be chosen in any order, and when they are active, they are colored grey. The channels
can also be seen and edited separately, allowing you to alter a single colour while still viewing the full-color image in your
image window.
5. How can we draw in a different colour in GIMP?
Ans. In Gimp, you must navigate to the box with two smaller boxes and an arrow at the bottom of the toolbar in order to draw
a different colour. The current foreground colour is shown in the box at the top, while the current background colour is
shown in the box at the bottom. You may choose whatever colour you want for either of the colour boxes by double-
clicking on either of them to bring up a colour selection tool. The new foreground or background colour is then that colour.
Future drawing processes will now make use of these colours.
