Renovate Images from Bitmap to Vector Format

Crisp images tell a good story. This is because they are traced back to the right path of construction. This can be done with an auto tracing software also. And professional editors doing daily photo editing often do it.

The magic of a clean image often lies in its scalable form. This happens when an image is transformed from bitmap to vector. Just like an embroider uses tracing material to draw out the basics and prepare a crisp tapestry, that is exactly what a professional editor does when he gets an image to be drawn to its finale. Sharp and cutting edge images break the blurs and presents clear-cut visuals.   The vectorization of bitmap images display better and are soothing to the naked eye. Most raster images of logos, products and several e-services undergo this process. Raster images are basically bitmap or in form of pixels in the square grid. It is a basic 2D format that needs an upgrade. When converted they represent an illusion of the real thing online. Logos used on websites, online studio professionals for this result often edit products sold on e-stores. Artworks of logos are the commonest that reach the editing table. 

How does the raster bitmap to vector work? 

The tracing can be done manually or by Auto-CAD. It can be a lengthy and a tedious process. But there are quicker ways to accomplish the feat.  But there are some pictures that cannot be converted for scaling in vector method. If they were made on paper or they are printed pictures then the process will not give crisp results. Even if the bitmap is done in Photoshop it will not be possible to make it sharp. Barring these limitations, the bitmap to vector can be processed easily. Only bitmap that has been produced from the digital raster of a vector original artwork can be edited in this method. This gives the scope for re-vectorization of the image.  The image is loaded from the clipboard and then it is transferred to the application required for the edit. Please make sure which format is being used PNG, Jpeg or GIF. This will also determine how the edited material will be converted after the process. A bitmap always will be dependent on the resolution.  When it is being re-formatted the quality drops. So the purpose of the final use of the image is also essential. For example, if this bitmap will be used as a data on the PC monitor it works will with less resolution. But even here the image will not be too sharp. If it is for the print media then it will need more dpi. Clarity in print is determined with the dense pixels only. 

Each time resizing and resampling makes a difference. Daily photo editors have encountered issues when they are asked to do this job of bitmap to vector conversions. There is a process of interpolation that makes the difference too. In the editing software the values of the color tones (of added pixels) are determined keeping in mind the existing ones. When the bitmap when enlarged is distorted- and is not good for printing. But if it is reduced the ppi is lesser and the picture clarity is better. Scaling does not impact on the finale layout of the image.
