The 16 pages that link to Image resolution, each with the reason it gives.
Raster graphicsRelated: Pixel dimensions set the grid's capacity to represent spatial detail.
Digital imageRelated: Pixel dimensions constrain the spatial detail available in a raster image.
Scientific illustrationRelated: Resolution limits which structures can be shown faithfully.
Image editingRelated: Resolution constrains resizing, cropping, and the detail retained after edits.
SamplingRelated: Pixel spacing determines how finely an image samples spatial variation.
GIMPRelated: Resolution affects the detail available for GIMP edits and the image's output size.
Image scannerRelated: Resolution describes the detail in a scan’s pixel grid.
2D computer graphicsRelated: It determines how much spatial detail raster images can preserve.
