Large illustrations frequently require reference counterparts that are shorter and more scalable. Therefore, scanning is required. However, to scan the drawings, they must first be electronically edited. High-resolution photographs are taken. The huge photos must then be resized to make scanning easier. If the photographs are in raster format, and aren’t scalable, the photo editor will typically treat them as blueprints.

The initial process before the editor takes control is to convert raster to vector. By altering the outlines of the drawings, he achieves this. If he obtains the drawings in their original format, he must first determine whether or not they are suitable for conversion from raster to vector.

What causes this to happen? The drawing may be very weak and thin, and the ink strokes may not be seen. They can't be scanned and converted to CAD. Hence, raster to vector conversion is required for a clear image.

The accuracy of the sketches is questioned if there’s too much text or repeated annotations. Apparently, messed-up patterns and multiple sketches might lead to a bad scan or even a failed raster-to-vector conversion. Unless the resolution is good, it’ll not result in clarity in this scenario.

Multiple factors are taken into account to avoid bad print quality. The original drawing should be forwarded to the editor for a review of what needs to be improved.

In the perspective of, the editor can begin by creating a clear background. This should also be able to erase creases often the original drawing is folded or rolled. Once the kinks are straightened out, a complete raster to vector conversion may be performed. When the editing process begins, the editor's ability to save the work is important. TIFF files are optimum for scanning if the photos will be digitized at some point. They provide the greatest amount of clarity.

For the conversion, the appropriate resolution is also necessary. The scan quality will be very bad if the resolution is lower. It'll be faded or blurred. The resolution is expressed in dots per inch (dpi). When converting raster to vector, a resolution of at least 300 dpi is recommended for clearly defined edges or lines. Vectorization is simple when the lines and curves are distinguishable. Commonly, images with a resolution of fewer than 300 dpi cannot be used to convert raster to vector. After re-scanning, there is a potential that the vector drawing will have a higher resolution for converting from raster to vector.
