Anyway that's a different story but I'm sharing it with you all because this incident gave me an interesting idea. Since I was able to reach login screen but couldn't log into Desktop, I thought that wouldn't it be great if we could get access to Command Prompt at login screen so that we can restore files or run other commands in case we are unable to log into Windows. Actually it happens many times when Windows crashes at login screen due to corrupt or missing system files and the only way to fix this kind of problem is to restore system or repair or reinstall Windows. So it would be really great if we can launch Command Prompt at login screen and then we'll be able to restore default system files if our modified file doesn't work properly. I know it would be a security risk and other people can execute commands to reset password, create or remove user accounts, etc using Command Prompt at login screen but it would not be the case if you are the only user of your computer. Now the question comes how can we access Command Prompt at login screen? By changing . Windows login screen contains an . Open Windows Explorer and go to C: \Windows\System.

Portable Network Graphics - Wikipedia. Portable Network Graphics (PNG. PNG was created as an improved, non- patented replacement for Graphics Interchange Format (GIF), and is the most widely used lossless image compression format on the Internet. PNG was designed for transferring images on the Internet, not for professional- quality print graphics, and therefore does not support non- RGB color spaces such as CMYK. A PNG file contains a single image in an extensible structure of . PNG was approved for this use by the Internet Engineering Steering Group on 1. October 1. 99. 6. There were also other problems with the GIF format that made a replacement desirable, notably its limit of 2. A January 1. 99. 5 precursory discussion thread, on the usenet newsgroup . In this thread, Oliver Fromme, author of the popular DOSJPEG viewer QPEG, proposed the PING name, meaning PING is not GIF, and also the PNG extension. MNG achieved moderate application support, but not enough among mainstream web browsers and no usage among web site designers or publishers. In 2. 00. 8, certain Mozilla developers published the Animated Portable Network Graphics (APNG) format with similar goals. ![]()

Chunks declare themselves as critical or ancillary, and a program encountering an ancillary chunk that it does not understand can safely ignore it. This chunk- based storage layer structure, similar in concept to a container format or to Amiga's. IFF, is designed to allow the PNG format to be extended while maintaining compatibility with older versions—it provides forward compatibility, and this same file structure (with different signature and chunks) is used in the associated MNG, JNG, and APNG formats. ![]() A chunk consists of four parts: length (4 bytes, big- endian), chunk type/name (4 bytes), chunk data (length bytes) and CRC (cyclic redundancy code/checksum; 4 bytes). The CRC is a network- byte- order CRC- 3. Show Related Stories Under Each Post! LinkWithin is a blog widget that appears under each post, linking to related stories from your blog archive. Length. Chunk type. Chunk data. CRC4 bytes. Length bytes. 4 bytes. Chunk types are given a four- letter case sensitive ASCII type/name; compare Four. CC. The case of the different letters in the name (bit 5 of the numeric value of the character) is a bit field that provides the decoder with some information on the nature of chunks it does not recognize. The case of the first letter indicates whether the chunk is critical or not. If the first letter is uppercase, the chunk is critical; if not, the chunk is ancillary. Critical chunks contain information that is necessary to read the file. If a decoder encounters a critical chunk it does not recognize, it must abort reading the file or supply the user with an appropriate warning. The case of the second letter indicates whether the chunk is . Uppercase is public and lowercase is private. This ensures that public and private chunk names can never conflict with each other (although two private chunk names could conflict). The third letter must be uppercase to conform to the PNG specification. It is reserved for future expansion. Decoders should treat a chunk with a lower case third letter the same as any other unrecognised chunk. The case of the fourth letter indicates whether the chunk is safe to copy by editors that do not recognize it. If lowercase, the chunk may be safely copied regardless of the extent of modifications to the file. If uppercase, it may only be copied if the modifications have not touched any critical chunks. Critical chunks. Such splitting increases filesize slightly, but makes it possible to generate a PNG in a streaming manner. The IDAT chunk contains the actual image data, which is the output stream of the compression algorithm. It is optional for color types 2 and 6 (truecolor and truecolor with alpha) and it must not appear for color types 0 and 4 (grayscale and grayscale with alpha). Ancillary chunks. PNG also supports color management through the inclusion of ICCcolor space profiles. It is intended for use when there is no better choice available, such as in standalone image viewers (but not web browsers; see below for more details). HRM gives the chromaticity coordinates of the display primaries and white point. AMA specifies gamma. IST can store the histogram, or total amount of each color in the image. CCP is an ICC color profile. TXt contains a keyword and UTF- 8 text, with encodings for possible compression and translations marked with language tag. The Extensible Metadata Platform (XMP) uses this chunk with a keyword 'XML: com. HYs holds the intended pixel size and/or aspect ratio of the image. BIT (significant bits) indicates the color- accuracy of the source data. PLT suggests a palette to use if the full range of colors is unavailable. RGB indicates that the standard s. RGB color space is used. TER stereo- image indicator chunk for stereoscopic images. Separator is a null character. Leading or trailing spaces are also disallowed. IME stores the time that the image was last changed. PNGOUTWin - batch mode png optimizer for Windows. See how optimized image compression can reduce bandwidth costs, improve website download times. RNS contains transparency information. For indexed images, it stores alpha channel values for one or more palette entries. For truecolor and grayscale images, it stores a single pixel value that is to be regarded as fully transparent. TXt contains compressed text (and a compression method marker) with the same limits as t. EXt. The lowercase first letter in these chunks indicates that they are not needed for the PNG specification. The lowercase last letter in some chunks indicates that they are safe to copy, even if the application concerned does not understand them. Pixel format. The palette is a separate table contained in the PLTE chunk. ![]() Sample data for a single pixel consists of a tuple of between one and four numbers. Whether the pixel data represents palette indices or explicit sample values, the numbers are referred to as channels and every number in the image is encoded with an identical format. The permitted formats encode each number as an unsigned integral value using a fixed number of bits, referred to in the PNG specification as the bit depth. ![]() ![]() Notice that this is not the same as color depth, which is commonly used to refer to the total number of bits in each pixel, not each channel. The permitted bit depths are summarized in the table along with the total number of bits used for each pixel. The number of channels will depend on whether the image is grayscale or color and whether it has an alpha channel. PNG allows the following combinations of channels, called the color type. The color type is specified as an 8- bit value however only the low 3 bits are used and, even then, only the five combinations listed above are permitted. So long as the color type is valid it can be considered as a bit field as summarized in the adjacent table: PNG color types. Colortype. Name. Binary. Masks ACP0. Grayscale. Truecolor. 00. 10color. Indexed. 00. 11color, palette. Grayscale and alpha. Truecolor and alpha. This is only valid in combination with bit value 2; bit value 2: the image samples contain three channels of data encoding trichromaticcolors, otherwise the image samples contain one channel of data encoding relative luminance,bit value 4: the image samples also contain an alpha channel expressed as a linear measure of the opacity of the pixel. This is not valid in combination with bit value 1. With indexed color images, the palette always stores trichromatic colors at a depth of 8 bits per channel (2. Additionally, an optional list of 8- bit alpha values for the palette entries may be included; if not included, or if shorter than the palette, the remaining palette entries are assumed to be opaque. The palette must not have more entries than the image bit depth allows for, but it may have fewer (for example, if an image with 8- bit pixels only uses 9. The palette must contain entries for all the pixel values present in the image. The standard allows indexed color PNGs to have 1, 2, 4 or 8 bits per pixel; grayscale images with no alpha channel may have 1, 2, 4, 8 or 1. Everything else uses a bit depth per channel of either 8 or 1. The combinations this allows are given in the table above. The standard requires that decoders can read all supported color formats, but many image editors can only produce a small subset of them. Transparency of image. With true- color and grayscale images either a single pixel value can be declared as transparent or an alpha channel can be added (enabling any percentage of partial transparency to be used). For paletted images, alpha values can be added to palette entries. The number of such values stored may be less than the total number of palette entries, in which case the remaining entries are considered fully opaque. The scanning of pixel values for binary transparency is supposed to be performed before any color reduction to avoid pixels' becoming unintentionally transparent. This is most likely to pose an issue for systems that can decode 1. Alpha storage can be . The same image as a GIF would be more than thirteen times larger. ![]() Download Start Menu Reviver - Major.
