4. Figure 4. General Outline of the crane self-balancing 2.1 Mechanical Design of the crane. To achieve the mechanical design of the tower crane, initially technical specifications are required, both the mechanical and the electrical and electronic components, such as motors, sensors, circuit cards, etc.
When to Use PNG. Use PNG when you need smaller file sizes with no loss in quality. PNG files are usually smaller than TIFFs, in my experience. PNG also supports alpha transparency (soft edges) and was developed to be a Web graphics replacement for GIF. Note that if you want to retain full transparency, you will need to save your PNG file as PNG-24 and not PNG-8. PNG-8 is useful for reducing the file size of PNG files when you don't need transparency, but it has the same color palette limitations as GIF files.
PNG format is a lossless compression file format, which makes it a common choice for use on the Web. PNG is a good choice for storing line drawings, text, and iconic graphics at a small file size. JPG format is a lossy compressed file format. This makes it useful for storing photographs at a smaller size than a BMP. JPG is a common choice for use on the Web because it is compressed. For storing line drawings, text, and iconic graphics at a smaller file size, GIF or PNG are better choices because they are lossless. JPEGs are for photographs and realistic images. PNGs are for line art, text-heavy images, and images with few colors.
