9) to meet the requirements of your supplier's machinery. Hand-drawn vector graphics can provide simpler object outlines (Fig. Vector Conversions specializes in manually drawn vector graphics such as the sample image below. 8) will work best for projects that require vectors-only.

Figure 7 shows a complex set of object outlines that may not be suitable for all processes.Ī simplified, manual vector drawing with fewer colors / objects (Fig.
#CONVERT RASTER TO VECTOR LINE DRAWING SOFTWARE#
While we see the image above as a bunch of colors that together form a flower, the processes that require vector graphics - such as software for plotters and cutters - see and are guided by the vector outline or "wireframe" of each object as shown below. *Processes that require vector OR high-resolution do not have the same limitations as those that require 100%, true, vector-only art. The more color objects that are created, the more realistic the vector image will look - BUT - those same processes that require vector-only* usually also require a limited amount of shapes/objects and/or a limited amount of colors. Because in vector graphics there are no tiny pixels of very similar color next to each other, there is no subtle gradation from one color to another but a distinct separation of color (Fig. Even the automated conversion software that knows the exact color and location of each pixel doesn't actually draw each pixel, instead it draws an object for each larger cluster of similarly colored pixels. To manually create an object for each different color pixel that exists in a photograph is improbable and for most purposes unwanted. A shape, also called an object, has to be created to enclose each different color. When the pixels are positioned with small incremental changes in color for each adjacent pixel, they form a nice and smooth color blend (Fig. The pixels are arranged to form recognizable imagery such as a photo. Raster formats support 16 million colors, and a 1k pixel square image has a million pixels. Photographs, like all raster images, are made up of hundreds of thousands of different colored pixels. Looking identical also defeats most purposes for creating a vector graphic. The easy answer is yes, to a discerning eye it is impossible especially if you are zoomed in excessively. So, is it impossible for a photograph to be reproduced in vector format and look identical to the photo? The material that the vector graphic will be on usually dictates how the vector graphic should be prepared. More options for single color vector drawings.
This style is usually required for engraving and etching. This style is usually required for specialty printing (cups, frisbees, certain cloth printing) and no-print signage.
See other samples with color gradients.įig. Not suitable for processes that require 100% true vector. If your supplier has requested vector or high resolution, then this style is acceptable. Color-blending effects within a vector program are actually raster effects. For some of these processes your image may need to be further modified to a black and white or single-color graphic.įig. We do not recommend Photo to Vector conversion unless what you expect is precisely that a drawing and not a more realistic representation such as a photograph.įortunately, vector graphics are usually only required for certain processes such as engraving and no-print signage made of carved-wood, metal, lighted materials, cut-vinyl, and sandblasted stone. Vector programs are drawing programs, so converting a photograph to vector format means making a drawing based on the photo. Vector conversion can be done either manually or with the aid of automated tools. Photo Vectorization is the process of converting a photograph - which is in raster format - to vector format by duplicating it with vector drawing software.
