The program is available in multiple languages, including English and Japanese and you can choose to install FireAlpaca in any of the available languages. The next step is to choose the folder to install FireAlpaca. You’ll need at least 91.3 MB of free space on your device to install it. When the installation is complete you can open the program and start using it. 3.1.15 Container formats of raster graphics editors.The size of raster image files is positively correlated with the number of pixels in the image and the color depth (bits per pixel). Images can be compressed in various ways, however. A compression algorithm stores either an exact representation or an approximation of the original image in a smaller number of bytes that can be expanded back to its uncompressed form with a corresponding decompression algorithm. Images with the same number of pixels and color depth can have very different compressed file size. Considering exactly the same compression, number of pixels, and color depth for two images, different graphical complexity of the original images may also result in very different file sizes after compression due to the nature of compression algorithms. With some compression formats, images that are less complex may result in smaller compressed file sizes. This characteristic sometimes results in a smaller file size for some lossless formats than lossy formats. images with large continuous regions like line art or animation sequences) may be losslessly compressed into a GIF or PNG format and result in a smaller file size than a lossy JPEG format.įor example, a 640 × 480 pixel image with 24-bit color would occupy almost a megabyte of space:Ħ40 × 480 × 24 = 7,372,800 bits = 921,600 bytes = 900 KiB For example, graphically simple images (i.e. With vector images the file size increases only with the addition of more vectors. There are two types of image file compression algorithms: lossless and lossy. Lossless compression algorithms reduce file size while preserving a perfect copy of the original uncompressed image. Lossless compression generally, but not always, results in larger files than lossy compression.
