Object Transformations
1. Introduction
In graphics and image editing software, object transformations are used to manipulate objects interactively. These transformations help in aligning, resizing, and adjusting objects in a design.
- Core feature of graphics software
- Works on shapes, images, and text
2. Types of Object Transformations
- Translation (Move)
- Scaling (Resize)
- Rotation
- Skew / Shear
- Reflection (Flip)
3. Translation
Translation moves an object from one position to another without changing its size or orientation.
- Horizontal and vertical movement
- Uses move or drag tool
4. Scaling
Scaling changes the size of an object by increasing or decreasing its width and height.
- Uniform scaling (proportional)
- Non-uniform scaling
5. Rotation
Rotation turns an object around a fixed point, usually its center, by a specified angle.
- Clockwise and anticlockwise rotation
- Angle measured in degrees
6. Skew / Shear
Skewing distorts an object by slanting it horizontally or vertically.
- Creates perspective-like effects
- Used in creative designs
7. Reflection
Reflection flips an object across a horizontal or vertical axis.
- Horizontal flip
- Vertical flip
8. Free Transform Tool
The free transform tool allows users to apply multiple transformations such as scaling, rotation, skewing, and flipping using a single tool.
- Common in Photoshop and similar tools
- Interactive handles
9. Advantages
- Flexible object manipulation
- Improves design accuracy
- Saves time and effort
10. Applications
- Graphic design and illustration
- Photo editing
- UI/UX layout design
- Animation and multimedia projects
