Vexel Art

Vexel art is a digital art that is an entirely pixel-based form of raster art that imitates the vector graphics technique, but is distinguished from normal vector graphics or raster images. “Vexel” itself is a mixture of two words ‘Vector’ and ‘Pixel’. Vexel designs are composed by using multiple layered shapes. It can be done in Photoshop, but vexel designs are not limited to only Photoshop; essentially, it can be done with any image editing software that has a good Pen Tool.

Vexel art 是一個數位藝術，這是一個完全基於像素的光柵藝術，它模仿的向量圖形技術，但有別於一般的向量圖形或光柵圖形。 “ Vexel ”此字本身是混合兩個詞彙"向量"與"像素"而成 。 Vexel設計都使用多個層次的形狀。這是可以在Photoshop做到的 ，但vexel設計不僅只限於使用Photoshop ;從本質上來說，這是可以用任何具有良好的鋼筆工具圖形的編輯軟體來做到的。
