Almost all the scanners save the scanned file in default JPG format. And the people generally expect that they can easily make the download of JPEG images online and then do the vectorization from it. But that is not the case. On the contrary it is seen that this image format is not at all suitable for effective Raster to Vector Conversion techniques. Reasons why jpg images are problematic for this conversion?
1. Whenever you try to save image in JPG format, some data will be lost so as to keep the file small.
2. It is to be noted that a scanned image with black and white color and also saved as a JPEG file will be larger than the same drawing being scanned in black and white but being saved as TIFF.
3. The image attributes that is essential for online display and those for raster to vector conversion are entirely different. For creating a smooth as well as crisp image for converting raster to vector image, the original drawing should be large or of higher resolution.
