StretchImage

StretchImage is a common term used in computer graphics and image processing to describe the process of resizing an image without maintaining its original aspect ratio. This means the width and height of the image are scaled independently, often resulting in distortion if the new dimensions do not perfectly match the original proportions. When an image is stretched, pixels are either duplicated or discarded to fill the new dimensions. This can lead to a visually unappealing result where objects appear wider or taller than they should. StretchImage is often contrasted with scaling an image proportionally, where the aspect ratio is preserved to avoid distortion. While stretching can be used intentionally for artistic effect, it is more commonly an unintended consequence of improper resizing. Developers and users typically aim for proportional scaling when resizing images for display or further processing to maintain visual integrity. Many image editing software programs offer options to either stretch an image or resize it proportionally, allowing the user to choose the desired outcome. The primary disadvantage of stretching is the loss of the original visual representation, which can be problematic in applications where accuracy is important.
