Disappearing points can simplify the process of perspective correction editing in an image that contains a perspective plane (such as a building's side, wall, ground, or any rectangular object. In the disappear point, you can specify a plane in the image, and then apply the painting, imitation, copy or paste, transform, and other editing operations. All editing operations use the perspective of the plane you are processing. When you modify, add, or remove content from an image, the results are m

When designing Web pages and program interfaces, most designers are worn out to ensure that each pixel's color, texture, and position are accurately presented. Accidentally, some of the most commonly used operations such as moving, rotating and pasting will make your hard work to naught. However, if you can make some small changes to your workflow, you can always keep the quality of the work in the project.
