This article originates from the Py2.7.9-docs faq.pdf "3.23 Why can ' t raw strings (r-strings) end with a backslash?"More precisely, the original string is an R-decorated string, and cannot end with an odd number of backslashes;The original string is designed to be used as input to some processors (primarily the regular expression engine). Such a processor would consider this unmatched end backslash to be an error, so the original string would not be

are required to output data in YUV format for processing it?1 YUV a pixel accounted for 2B, if the pixel is too high in the high clock baseband chip processing, JPEG data volume will be much smaller, so it is not YUV to baseband chip requirements but baseband chip to the output data rate requirements.2 RGB565 generally used on the very low-end baseband chip, directly to the screen brush. YUV output brightness signal does not have any loss, and color bias signal human eye is not particularly sen

Raw is a digital camera special format, can be called "electronic film", is the original image encoding data. Raw format photos record the digital camera sensor raw information and some of the data generated by the camera, including the image of sharpness, saturation, contra

Panorama Synthetic Distortion control is more excellent than PS Camera Raw is the most familiar with the raw file processing tools, with recent updates, Camera raw function more and more rich, in addition to the original regulation of content, Camera raw adjustment independence is also more and more strong, some

Before creating a virtual machine, first add a virtual machine disk, use image in KVM to represent the virtual disk, and before adding the virtual machine diskFirst you need to know how to make an imageQEMU-IMG is a Disk management tool for QEMUOne, image creation in RAW format1. Create an image in

Camera Raw Basic Use method Taking photos in RAW format is a big advantage for digital SLR cameras. Raw format contains a large number of image information, compared to the JPEG format adjustment is more powerful, while the resulting loss of the screen is correspondingly lower, we will introduce Photoshop camera

Raw file as a kind of image storage data format, only record the original information of the digital camera sensor, provide more flexibility for the post-processing of the digital image, which is favored by many photographers. In general, we can use the official software to buy the camera to open and process raw format

Selection of Virtual Machine hard disk formats: qcow2, raw, etc.There was a time when I was confused about the format of Virtual Machine hard disk. In 2009, I finally came to some conclusions (the following ideas are basically applicable to other virtual machines)After searching, we found that qcow2 is used as the virtual hard disk by default for most qemu or KVM instances, but qemu uses raw by default.The

I recently studied the image format of virtual machines and wrote a note to record these things. In linux, there are many ways to choose virtual machines, such as vmware for linux, virtual box, And qemu. In the past, there were not many people using qemu, mainly because it was a little troublesome to use, however, with the rise of Openstack, qemu has also been greatly developed. Currently, the performance of qemu + kvm in Fedora is still very good. It

Oracle used raw via lvm to handle raw usage issues for a production database of another company in the morning. On-site staff said they would use the new lvm space for oracle, and lv had already been made, the ing is also bound, but raw is not visible all the time. After checking the relevant binding rule parameters and binding the rules in use, the new rules are

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 JPEG file 两、三倍, it is not difficult to imagine,

Oracle RAC 10.2.0.5 Install For redhat 5.8 (use raw device) Because the customer's database needs to be patched, similar test environments are installed. You must first install Oracle RAC 10.2.0.1 and then upgrade it to 10.2.0.5. Because I have many articles about installation, this article only describes the key steps and the bug installation errors. Note: I have tested it in RedHat 6.3 and cannot install it. It is mainly because it fails to pass the

The data output format of the camera is generally divided into ccir601, ccir656, raw RGB and other formats. Here, the RGB format should be ccir601 or ccir656. The raw RGB format is different from the normal RGB format. We know that the sensor's photosensitive principle is to sample and quantify the light by one photosensitive point. However, in the sensor, each photosensitive point can only be a color in

Restore, select a available disk to save your recovered files on the line;7, the final format of the problem of the disk to restore the file back OK everything is intact. 5. Use Norton PartitionMagic 8.0 for recovery.
