Are you familiar in 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.
In short the image is still rasterize or pixelated.
What about the VECTOR art?
Vector artwork is a term that describes any art made with vector illustration software like Adobe Illustrator. Vector artwork is built from vector graphics, which are images created with mathematical formulas. In comparison, raster art (also referred to as bitmaps or raster images) is created with colorized pixels. Enlarge pixel-based art in a raster file too much and it looks jaggy, whereas you can enlarge vector art to any size without negatively affecting its appearance. This resolution independence allows vector art to be used in a variety of forms, from small illustrations to massive billboards.
Even you enlarge the vector art using AI, it's still fine or sharp. But if you are going to save your vector art into a image like jpg, png, etc. the image will turn into raster image, even you save it into 300 ppi, it's still rasterize.
So even you use the Photoshop for VEXEL and Illustration for Vector, It will remain raster image.
