What is pdf rasterization?

The process of converting the codes contained in the portable document format (PDF) to a two -dimensional (2D) image is called pdf rasterization. The information stored in the PDF file can provide instructions to the program or device to display the document, but when displaying the screen, the results must be drawn in 2D space. Depending on the type of objects used in the PDF document, the PDF rasterization process may sometimes be accelerated by graphical hardware, which is much in the same way as the three -dimensional (3D) graphics are calculated. PDF rasterization is associated with a number of complex problems, especially if the document contains dynamic interactive elements or programming scripts that rely on external objects that are not easily converted to a static 2D figure.

The PDF document is stored as a number of instructions and numbers that can communicate the HOW program to draw not only the text on the page, but also any graphics that KTErá is required, whether they are compressed pictures or vector line art. PDF file information is stored in this way, so it can be completely independent of the use of devices to render, display or print without losing quality. Although there are PostScript® printers or vector-based displays that can natively display a PDF document, most practical systems need to be converted to 2D image instructions, so they can be used by hardware such as monitors and home printers.

pdf rasterization includes the use of mathematical formulas and some other techniques to translate objects such as Bezier curves, lines and fonts on flat areas, pixel from pixel. The PDF file stores how to draw information, so the racor image processor (RIP) can make a PDF document as large or small as required without any quality loss. One case in which this may not be real indoor -rast files of Lves photographic style thatThey are inserted or coded in the PDF document and the number of pixels is already set and cannot be adjusted without interpolation that could reduce quality.

Many computers perform pdf rasterization daily. The PDF reader, such as those used in web browsers, can quickly portray PDF files, so they can be read, although the display speed is sometimes allowed to reduce quality because the program receives shortcuts. Whenever a PDF document is printed, it must also be rasterized before sending to the hardware. Mobile devices often have the functionality of PDF rasterization directly into their operating systems to allow accurate accelerated hardware rendering, regardless of the size of the output field.
