Complete the statement: 'When you __________ an image, the number of pixels in the image changes.'

When you resize an image, the number of pixels in the image changes. Resizing involves altering the dimensions of the image, which directly affects the pixel count. Increasing the image size typically requires interpolation, which adds new pixels based on the existing data, while decreasing the size reduces the total number of pixels as the image is scaled down.

Cropping an image, on the other hand, involves removing parts of the image without necessarily altering the overall size of what remains, but it does reduce the pixel count. Transforming an image can involve scaling, rotating, or skewing it, which doesn't always mean the pixel count will change as scaling could be interpreted in multiple ways, including no actual increase or decrease in detail. Adjusting an image typically refers to changing properties like brightness, contrast, or color, which doesn’t involve changing the pixel dimensions.

Therefore, the option that correctly states that the number of pixels in the image changes is when you resize an image.
