Shapes and Layers
Shapes and layers are fundamental concepts in graphics
and image editing software. Shapes define visual objects,
while layers help organize and manage different elements
independently.
1. Introduction
Modern graphics tools use shapes and layers to create complex designs efficiently. Layers allow designers to work on individual components without affecting others.
- Core features of graphics editors
- Improve workflow and control
2. Shapes
Shapes are basic graphical objects created using geometric definitions. They can be filled with colors, gradients, or patterns.
- Vector-based objects
- Scalable without quality loss
3. Types of Shapes
- Rectangle and Square
- Circle and Ellipse
- Line and Polygon
- Custom shapes
4. Shape Properties
Each shape has editable properties that control its appearance and behavior.
- Fill color and stroke
- Stroke width and style
- Opacity and effects
5. Layers
Layers act like transparent sheets stacked on top of each other. Each layer can contain shapes, images, text, or effects.
- Independent editing
- Better project organization
6. Types of Layers
- Image layers
- Shape layers
- Text layers
- Adjustment layers
7. Layer Operations
- Create, delete, and duplicate layers
- Reorder layers (stacking order)
- Hide, lock, and merge layers
8. Layer Opacity and Blending
Opacity controls layer transparency, while blending modes define how layers interact visually.
- Opacity (0%–100%)
- Blending modes (Normal, Multiply, Overlay)
9. Advantages
- Non-destructive editing
- Easy design modification
- Efficient collaboration
10. Applications
- Graphic design and illustration
- Photo editing
- UI/UX design
- Digital artwork
