How do you calculate the space occupied by an image in memory?
Understand the Problem
The question is asking how to calculate the space occupied by an image in memory, which involves understanding the relationship between resolution and pixel space.
Answer
Multiply the image's width, height, and bit depth, then divide by 8.
To calculate the space occupied by an image in memory, multiply the image's width, height, and bit depth (e.g., 24 for a 24-bit color image) and divide by 8 to convert bits to bytes.
Answer for screen readers
To calculate the space occupied by an image in memory, multiply the image's width, height, and bit depth (e.g., 24 for a 24-bit color image) and divide by 8 to convert bits to bytes.
More Information
Image file sizes can vary if the images are compressed. This calculation assumes uncompressed images.
Tips
A common mistake is forgetting to convert bits to bytes by dividing the result by 8.
