What's the difference between a page in word and a normal page? 2. What's the difference? bmp，。 psd，。 jpeg，。 Jpg suffix and other formats? Please give an example!

1. Normal view: it is the most basic view mode of Word and the default view mode of Word. It can display a complete text format, but it simplifies the page layout of the document (for example, it does not display the graphics embedded in the document, headers and footers), and its display speed is relatively fast, which is very suitable for the text entry stage. Users can enter and edit text in this view mode, and format the text.

Page view mode: display directly according to the page size set by the user. At this time, the display effect is completely consistent with the printing effect, and users can see the actual printing positions of various objects (including headers, footers, watermarks, graphics, etc. ) In a page, this is very useful for editing headers and footers, adjusting margins, and treating borders and graphic objects as columns.

2.PSD file format: It is a special file format of Photoshop image processing software. The file extension is. PSD can support various image features of layers, channels, masks and different color modes. It is an uncompressed original file storage format. PSD file sometimes has a large capacity, but because it can retain all the original information, it is the best choice to save the unfinished image in PSD format in image processing.

BMP image file format: BMP is an image file format that has nothing to do with hardware devices and is widely used. It uses bitmap storage format and does not use any other compression except image depth, so BMP files take up a lot of space.

BMP is a Windows bitmap, which can store a single raster image with any color depth (from black and white to 24-bit color). Windows bitmap file format is compatible with other Microsoft Windows programs. It does not support file compression, nor does it apply to web pages. Generally speaking, the disadvantages of Windows bitmap file format outweigh the advantages.

JPEG file format: JPEG is the abbreviation of Joint Photographic Experts Group, and the file name is ".. jpg" or ". Jpeg ",which is the most commonly used image file format. It is a lossy compression format organized by the Software Development Association, which can compress images in a small storage space, and duplicate or unimportant data in images will be lost, which will easily cause damage to image data. Especially, if the compression ratio is too high, the quality of the restored image after final decompression will obviously decrease. If you pursue high-quality images, you should not use too high compression ratio. But JPEG compression technology is very advanced. It uses lossy compression to remove redundant image data, and can display very rich and vivid images at the same time, in other words, it can obtain better image quality with the least disk space. JPEG format is the most popular image format on the Internet at present, which can compress files to a minimum.
