Pixelating vector line art

Abstract

a) Input vector line art (b) Pixelated outputFigure 1: Our algorithm converts vector line art into pixel drawings. It also allows users to draw and edit the vector components while providing real-time feedback on the pixelated result.

Evaluating and Validating Non-photorealistic and Illustrative Rendering

“…The question of which specific primitive to use to depict a given shape not only applies to line renderings of 3D shapes but even more so to pixel art, a unique form of expression arising from early computer depiction [14,28]. Recently, the question of how to generate such pixel representations from images or vector graphics was examined and evaluated [14,28].…”

“…Recently, the question of how to generate such pixel representations from images or vector graphics was examined and evaluated [14,28]. For example, Inglis and Kaplan [28] create pixel art from vector line drawings and evaluated these by comparing hand-created images with their automatic technique.…”

“…Recently, the question of how to generate such pixel representations from images or vector graphics was examined and evaluated [14,28]. For example, Inglis and Kaplan [28] create pixel art from vector line drawings and evaluated these by comparing hand-created images with their automatic technique. To achieve this comparison, they first asked their participants to create pixel images for given vector input using a Web tool, and in a second stage asked them to compare these images with each other as well as with synthetically generated ones.…”

Cartesian Resizing of Line Drawing Pictures for Pixel Line Arts

“…Approaches [1]- [3] of downscaling color photographs are useful, but they need color quantization and edge detection by image filters which are hard to work stably. Hence an approach simplifying the NPR problem by limiting input images to line drawings has been proposed [4]. We, in this letter, also consider the downsizing of line pictures.…”

“…We, in this letter, also consider the downsizing of line pictures. Inglis and Kaplan [4] assumed vector images to be inputted, hence their method cannot be applied to bitmap images made by paint software. They attempted to maintain the form of objects while the topological properties of images such as connectivity of lines and segments are not preserved in their method.…”
