Image Editing

Positioning an image precisely involves accurately placing it within a document or media:

• Typically achieved by selecting and dragging the image to the desired location.
• Some software offers more precise placement options, such as using coordinates or alignment tools.

Resizing an image entails altering its dimensions:

• Resizing an image is typically accomplished by selecting it and adjusting its corners or edges.
• Keeping the aspect ratio intact ensures that changes to the image's width and height occur proportionally, preventing distortion.
• Altering the aspect ratio can modify the image's shape and proportions.

Cropping an image involves removing unwanted parts:

• Crop tools allow users to select the area to retain while discarding the rest.

Rotating an image means turning it around a central point:

• Most software allows rotation to any angle, with common options like 90 or 180 degrees readily available.

Flipping an image creates a mirror image of the original:

• It can be done horizontally (left to right) or vertically (top to bottom).

Adjusting brightness and contrast modifies light and dark values:

• Brightness uniformly impacts all pixels, resulting in either a lighter or darker image overall.
• Contrast modifies the distinction between light and dark values, influencing the image's level of detail.

Grouping and layering images aid in organizing multiple images:

• Grouping combines images for unified movement or transformation.
• Layering involves stacking images, with options to reorder them or adjust their visibility.
