Complete Revision Notes, Accurate Board Exam Facts & Important Practice Questions
1. Introduction & Image Fundamentals
Exam Definition: A Digital Image is a computer picture formed by a grid of tiny colored dots called Pixels (Picture Elements). A pixel is the smallest individual dot of an image on a screen.
Common Image Formats (Class 10 Syllabus)
| Format | Full Form | Features / Where to Use |
|---|---|---|
| JPG / JPEG | Joint Photographic Experts Group | Best for photographs and realistic graphics with natural colors. |
| PNG | Portable Network Graphics | Supports transparent backgrounds. Best for logos, icons, and diagrams. |
| GIF | Graphics Interchange Format | Supports simple, short animations and up to 256 colors. |
| BMP | Bitmap Image File | Uncompressed raw image file. Gives great quality but takes large file storage. |
2. Methods to Insert Images in LibreOffice Writer
LibreOffice Writer provides four common ways to insert images into your document:
1. Insert Image Menu Dialog
Click your mouse on the document where you want the picture. Go to the top menu: Insert > Image..., browse your computer folder, select the picture file, and click Open.
2. Drag and Drop Method
Open your computer's folder window next to LibreOffice Writer. Click and hold the picture file with the mouse, drag it into the Writer document, and release the mouse button.
3. Copy and Paste Method
Select any image from another file, webpage, or folder, press Ctrl + C to copy it, click inside your Writer document, and press Ctrl + V to paste it.
4. Linking an Image File
When using Insert > Image, check the Link checkbox before clicking Open. Writer saves only the folder path (address) of the image instead of embedding the image file inside.
Important Advantage: Keeps your Writer file size very small.
Risk: If you move, rename, or delete the original picture file from your computer, the picture will stop showing in the document.
Risk: If you move, rename, or delete the original picture file from your computer, the picture will stop showing in the document.
3. Embedded Image vs. Linked Image
| Feature | Embedded Image | Linked Image |
|---|---|---|
| Where is it saved? | A copy of the picture is saved directly inside the document. | Only the address link (file path) is saved inside the document. |
| Document File Size | Large (document size increases with each image). | Very small (size remains light). |
| Sharing / Portability | Safe and portable. You can email the document and pictures will always show. | Requires care. If original image is deleted or not sent together, images break. |
| Original File Safety | Deleting the original picture from your PC does not affect your document. | Deleting or moving the original picture breaks the image in Writer. |
Memory Tip for Board Exams:
• Embed: Image lives inside the document file.
• Link: Document only remembers where the image is kept on your computer drive.

4. Modifying Images & Image Toolbar
Resizing
Changes the width and height of an image.
Rule: Always drag from the corner handle so the photo does not stretch or get distorted.
Rule: Always drag from the corner handle so the photo does not stretch or get distorted.
Cropping
Cuts off and removes unwanted outer background areas of an image without changing the size of the important middle part.
Rotating
Spins the picture around its center to change its angle (e.g., 90° or 180°).
Deleting
Click once on the image and press the Delete or Backspace key on your keyboard.
Image Toolbar Options
When you click on any image, the Image Toolbar opens automatically with these tools:
Graphics Mode
Changes visual look: Default (normal colors), Grayscale (black & white shades), Black/White (pure high-contrast), and Watermark (faded, faint image for background text).
Image Filters
Applies artistic visual effects: Invert (reverses color values), Smooth (softens edges), Sharpen (crisp details), Remove Noise, and Charcoal Sketch.
Color & Transparency
Fine-tunes Red, Green, Blue color channels, changes Brightness and Contrast, and adjusts Transparency (0% to 100%) so background text can show through.
Important Board Difference: Resizing vs. Cropping
• Resizing: Makes the whole image smaller or bigger (all contents stay visible).
• Cropping: Cuts off and throws away unwanted edges or backgrounds.
• Resizing: Makes the whole image smaller or bigger (all contents stay visible).
• Cropping: Cuts off and throws away unwanted edges or backgrounds.
5. Drawing Objects & Grouping
Exam Definition: Drawing Objects are shapes, lines, arrows, callouts, and flowchart banners drawn directly in Writer using the Drawing Toolbar.
Modifying Drawing Properties
You can customize drawn shapes using the Drawing Object Properties toolbar:
- Line Style & Width: Make borders thick, thin, dotted, or colored.
- Area Fill: Fill shapes with solid colors, color gradients, shading patterns, or textures.
- Shadow & Transparency: Add drop shadows and set transparency levels.
Grouping Drawing Objects
Grouping joins multiple small shapes into one single object so they stay perfectly combined.
1
Click the first shape, then hold down the Shift key and click each remaining shape you want to include.
2
Right-click on the shapes and choose Group > Group (or go to top menu Format > Group > Group, or shortcut Ctrl + Shift + G).
Why should we group objects?
1. Move all combined shapes together without disturbing their layout.
2. Resize the whole diagram uniformly in one step.

2. Resize the whole diagram uniformly in one step.
6. Positioning Objects in Text (A-A-A-W Framework)
Positioning controls how an image sits with the surrounding text and pages. Remember the A-A-A-W rule:
1. Arrangement (Layer Order)
Decides which object stays on top or behind when multiple pictures or shapes overlap.
Options: Bring to Front (puts on top of everything), Send to Back (puts behind everything), Bring Forward, Send Backward, and To Background (sits behind the page text).
2. Anchoring (Attachment Point)
Specifies what part of the document the picture is attached or tied to.
Options:
• To Page: Image stays at that exact page location forever.
• To Paragraph: Image is attached to a paragraph; if text above pushes the paragraph down, the picture moves down with it.
• To Character: Image is linked to a single letter or character.
• As Character: Image acts like a text character right inside the line of text.
• To Page: Image stays at that exact page location forever.
• To Paragraph: Image is attached to a paragraph; if text above pushes the paragraph down, the picture moves down with it.
• To Character: Image is linked to a single letter or character.
• As Character: Image acts like a text character right inside the line of text.
3. Alignment (Placement)
Controls the exact position of the image relative to its anchor point.
Options: Horizontal (Left, Centered, Right) and Vertical (Top, Center, Bottom).
4. Text Wrapping (Text Flow)
Decides how paragraph text flows around the boundaries of the image.
Options:
• Wrap Off: Text stops above the image and continues below it (no text on sides).
• Page Wrap: Text flows neatly on all four sides of the image.
• Optimal Page Wrap: Writer automatically flows text on whichever side has more room.
• Wrap Left / Wrap Right: Text flows only on the left or only on the right side.
• Wrap Through: Picture sits right on top of or behind text, allowing text to write across it.
• Wrap Off: Text stops above the image and continues below it (no text on sides).
• Page Wrap: Text flows neatly on all four sides of the image.
• Optimal Page Wrap: Writer automatically flows text on whichever side has more room.
• Wrap Left / Wrap Right: Text flows only on the left or only on the right side.
• Wrap Through: Picture sits right on top of or behind text, allowing text to write across it.
Board Exam Formula (A-A-A-W):
Arrangement (Front/Back) ➔ Anchoring (Attachment) ➔ Alignment (Left/Center/Right) ➔ Text Wrapping (Flow around photo)
Arrangement (Front/Back) ➔ Anchoring (Attachment) ➔ Alignment (Left/Center/Right) ➔ Text Wrapping (Flow around photo)
7. Step-by-Step Image Formatting Workflow
Follow this standard sequence when working with images in LibreOffice Writer:
1
Insert Image: Use Insert > Image..., Drag and Drop, or Copy-Paste (Ctrl + C / Ctrl + V).
2
Resize Carefully: Click and drag a corner handle to keep the original proportions intact.
3
Crop Background: Use the Crop tool from the Image Toolbar to trim unwanted borders.
4
Apply Anchoring: Set Anchor to To Paragraph so the photo moves naturally with your writing.
5
Apply Alignment & Wrapping: Choose alignment (Center or Right) and set Page Wrap so text flows cleanly around the picture.
6
Arrange & Group: Use Arrangement if shapes overlap, and Group (Ctrl + Shift + G) multiple shapes together.
Workflow Sequence:
Insert Image
➔
Resize Corner
➔
Crop Edges
➔
Anchor to Paragraph
➔
Page Wrap
➔
Group Shapes

Q4. What is the difference between an Embedded Image and a Linked Image?
Answer:
• Embedded Image: A copy of the picture is saved inside the document. It increases file size, but the file can be safely emailed to anyone.
• Linked Image: Only the computer path (address) of the image is saved. It keeps the document lightweight, but needs the source image file in the same location to display.
• Embedded Image: A copy of the picture is saved inside the document. It increases file size, but the file can be safely emailed to anyone.
• Linked Image: Only the computer path (address) of the image is saved. It keeps the document lightweight, but needs the source image file in the same location to display.

Q7. What are drawing objects in LibreOffice Writer? Give two benefits of grouping them.
Answer:
Drawing Objects: Visual vector shapes created directly inside Writer using the Drawing Toolbar (rectangles, arrows, stars, flowcharts).
Two Benefits of Grouping:
1. Multiple shapes turn into one unit, so you can move the entire drawing together without ruining its arrangement.
2. You can resize or scale the complete diagram uniformly in one single step.
