What formats are there?

The exchangeable image file format (EXIF for short) and the digital camera image file format advocated by Fuji Company in 1994 are actually the same as JPEG format, but the difference is that in addition to image data, exposure data such as shooting date, aperture, shutter and flash data, additional information and small-size images can also be stored.

2.FPX format

Flash photo (fpx for short, full name Kodak Flash PiX) is an extension of the image file format, which was jointly developed by Kodak, Microsoft, Hewlett-Packard and Live PictureInc, and officially released in June 1996.

FPX is an image format with multiple resolutions, that is, images are stored in a series of different resolutions. The advantage of this format is that the image quality can still be maintained when the image is enlarged.

In addition, when the FPX image is modified, only the modified part will be processed, and the whole image will not be processed at the same time, thus reducing the burden on the processor and memory and reducing the image processing time. Its multi-resolution storage mode is favored by many people.

3.SVG format

Scalable vector graphics (SVG for short). It is based on XML (a subset of standard generalized markup language) and developed by World Wide Web Consortium.

An open standard vector graphics language, which can enlarge the graphics display at will, has extremely clear edges, keeps the text editable and searchable in SVG images, has no font restrictions, generates small files and has fast download speed, and is very suitable for designing high-resolution Web graphics pages.

4.PSD format

PhotoShopDocument(PSD) 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. Scanners cannot directly generate files in this 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.

5.CDR format

CDR format is a special graphic file format of CorelDRAW, a famous drawing software. Because CorelDRAW is a vector graphics drawing software, CDR can record the attributes, location and paging of files. However, it has poor compatibility and can be used in all CorelDraw applications, but other image editing software cannot open such files.

6.PCD format

Photo CD (foreign abbreviation: PCD, foreign full name: kodak PhotoCD), with file extension. PCD, a photo CD file format developed by Kodak, can only be read by other software systems.

This format uses YCC color mode to define colors in images. YCC and CIE color spaces contain much more colors than RGB and CMYK colors of displays and printing devices. Most of the PhotoCD images are of very high quality.

7.UFO format

It is a special image format of the famous image editing software Ulead Photolmapct, which can completely record all the image attributes processed by PhotoMapCT. It is worth mentioning that UFO files use objects instead of layers to record image information.
