One, JPEG is a compressed photo
The basic difference is that the RAW file will fully retain the image of each pixel message and information, but JPEG is a camera based on a compromise compression, so the size of the two files are significantly different, RAW files can be
Q: After I take a picture of JPEG format, is there any way to adjust the white balance of the photo? Or does a similar adjustment only apply to RAW format?
A: Strictly speaking, you'd better use raw format to shoot, so that in the later editing process, the balance of the dialogue in the lossless adjustment. Since the automatic white balance is not foolproof, th
advantage of this format is that when the network is slow, you can see the outline of the picture to know what the picture is loading. You'll notice this technique when you open a larger picture on some Web sites.
If your speed and the same as the snail, you should be able to see the effect, in fact, you in Qzone, Weibo and other large sites you will often see this effect.
The PHP code can also convert it into a progressive jpg.

CBR format Comics to convert to JPEG method
CBR is a popular and common electronic comic format in the Internet, which is often found in European and American comic books. CBR has a small size, suitable for circulation on the network characteristics. But many devices do not support CBR, so how to convert CBR to JPEG s
VC + + in JPEG and BMP image format should be often encountered, JPEG compared to BMP in the image size has a great advantage.This article focuses on using the existing CImage class to convert in memory, without saving as a file, or introducing a third-party library.The Libjpeg library also supports memory reading and conversion after 8, but it is cumbersome to u
VC ++ uses CImage to convert Jpeg images in the memory,
Previously, I wrote an article titled converting Bmp images from Jpeg to CImage in memory using VC ++, and converting Jpeg to Bmp in memory using CImage.
Since Jpeg can be converted to Bmp, CImage also supports converti

2. Convert TIFF images to PNG or JPEG format, because the tools do not support the direct conversion of TIFF to PDF. My conversion method is a batch conversion with the conversion format of the tool , Gthumb, for this software, because
support sparse files, images in this format only use the space actually used by the data recorded in them.The old format is bare, that is, naked. You can simulate an image in raw format by dd a file. The performance is good because it is bare and thorough. Currently, the default formats of KVM and xen seem to be the same. Because of its original nature, there are many native features, such as direct mounting is also a simple task.The advantage of Bar
