How are hot spot coordinates related to the pixel size of an image?

Hot spot coordinates refer to specific locations on an image that trigger an action or function, such as in image maps used in web development. The relationship between hot spot coordinates and the pixel size of the image is that the coordinates are directly dependent on the dimensions and size of the image itself.

When you change the pixel size—either by resizing the image or altering its resolution—the positions of the hot spots relative to the image are affected. If the image is enlarged or reduced, the hot spots need to be recalibrated to maintain their intended positions because they are defined as specific pixel locations on that image. In essence, if the image's pixel dimensions change, the pixel locations of hot spots must be adjusted to ensure they still correspond correctly to the intended areas of interaction within that image.

This dependency on pixel size is crucial for ensuring that interactions are accurately detected in relation to the visual elements displayed on the screen. The need for recalibrating coordinates to match the altered image size makes it clear that the coordinates are not fixed but rather rely on the specific pixel dimensions of the image used.
