Image Editing (CIE IGCSE ICT)

Placing an image with precision: This refers to positioning an image accurately within a document or other media

• You can usually do this by selecting the image and dragging it to the desired location
• Some software allows for more precision through the use of coordinates or alignment tools
  
  

Resizing an image: This means changing the dimensions of an image

• You can often do this by selecting the image and dragging its corners or edges
• Maintaining the aspect ratio means the image's width and height change at the same rate, preventing distortion
• Adjusting the aspect ratio can change the shape and proportions of the image
  
  

Cropping an image: This involves cutting out and discarding parts of an image

• Cropping tools usually allow you to select a portion of the image to keep and discard the rest
  
  

Rotating an image: This means turning the image around a central point

• Most software allows rotation to any angle, and common rotations such as 90 degrees or 180 degrees are often provided as options
  
  

Reflecting (flipping) an image: This means creating a mirror image of the original

• An image can be flipped horizontally (left to right) or vertically (top to bottom)
  
  

Adjusting brightness and contrast: These tools change the light and dark values in an image

• Brightness affects all pixels in the image equally, making the image lighter or darker
• Contrast adjusts the difference between light and dark values, which can make the image appear more or less detailed
  
  

Grouping and layering images: These techniques help to organise multiple images

• Grouping combines images so they can be moved or transformed as a single unit
• Layering involves placing images on top of each other
• You can change the order of layered images, moving them to the front or back
