  • 说明JPEG – is a popular graphic format, which is characterized by a high degree of compression, which leads to a decrease in image quality. It uses the technology of encoding of smooth color renditions, providing the ability to reduce the amount of data frequently during the recording of the image. Because of the small size it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPEG algorithm is optimally suitable for compressing photographs and pictures, in which realistic scenes with little contrast of colors are present. It is not recommended to use this format for compression of drawings and various kinds of graphics, since a strong contrast between a number of closely located pixels provokes the appearance of visible artifacts.
  • 技术细节The procedure for compressing the digital images in JPEG format is carried out in several stages. First, the photo is transformed into a color space YCbCr, then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial.

  • 文件扩展名.psd
  • 文件类别images
  • 程序Adobe Illustrator CS6Adobe InDesign CS6GIMP
  • 主程序Adobe Photoshop
  • 说明PSD - 是由Adobe Photoshop最受欢迎的图形编辑器之一创建的图像。 与这种格式一起,来自“Photoshop”的各种数据也可以与“Photoshop”相结合。 可用,包括文本,图形图层或注释。 扩展可以支持多种灰度,单色图像,以及CMYK和RGB颜色模型。 这些文件可以转换成各种格式(JEPG,PNG等),以便后续传输或存储。 更改格式后,所有图层都会转换为一个图层,这在使用PSD扩展程序保存时不会发生。 在这种情况下,它们可供查看和编辑,这使得它们对于处理各种文档的草稿特别有用。 保存中间结果时,格式是不可替代的。 大多数版本的Photoshop以及其他Adobe程序都支持它。
  • 技术细节PSD扩展的特点是能够支持各种可视化选项,包括蒙版,专色,双色设置,剪裁。 在某些情况下,有一些扩展名为.psb的文件,它支持宽度和高度分辨率限制为3万像素。 PSD文件使用RLE压缩算法,该算法允许以最小的损失进行压缩。 但是,它们仍然很大,因此最好使用存档器将它们存储在磁盘上。
  • MIME类型application/psdapplication/octet-stream
