{{FormatInfo

'''Garmin vehicle images file''', or '''SRF''', is a raster graphics format associated with Garmin GPS devices. An SRF file contains images that comprise an avatar of a vehicle. An SRF file will often be distributed inside a [[ZIP]] file.

== Identification ==
An SRF file begins with ASCII "{{magic|GARMIN BITMAP 01}}".

'''IPLab''' (Image Processing Lab) is image software apparently used in scientific applications, producing image files with a .ipl extension that are apparently raster images and can have multiple images in a file. This is one of the formats that is spottily documented online, with a few scattered references (and one can never be sure that they're even all to the same software; "Image Processing Lab" is a pretty generic name).

The format was developed by Scanalytics for use with advanced digital microscopes.

The software from AForce.NET called IPLab is definitely unrelated. It is written in C# and relies on the built in system classes for loading images.

ANSI Art

2023-02-19T22:33:39Z

Fabel: The visual appearance corresponding to those code points are just a consequence of the PC graphics implementation. Also, the code pages only affects code points above 127, code points from 0 to 127 are covered by the ASCII standard (ANSI X3.4-1968).

{{FormatInfo
|formattype=electronic
|subcat=Graphics
|extensions={{ext|ans}}, others
}}
'''ANSI Art''' is a variant on [[ASCII Art]] which uses [[ANSI escape code|ANSI escape sequences]] in addition to ASCII characters in order to do things like changing colors. It also uses characters from the [[MS-DOS encodings|IBM PC code page]] which aren't part of ASCII, allowing a wider range of characters including various graphical symbols and box-drawing characters. This sort of art was popular on bulletin board systems in the late 1980s and early 1990s, and in other communities through the early 2000s. It is still being made in small quantities today.

== Disambiguation ==
The term "ANSI Art" sometimes refers to the file format (text with ANSI control sequences), and sometimes to the artwork itself. In the latter sense, "ANSI Art" graphics might be stored in a file format other than ANSI Art format, such as [[BIN (Binary Text)|BIN]] or [[iCEDraw]].

== Format details ==
As far as we know, there is no formal specification of ANSI Art format. It has many variants and extensions, and there is usually no easy way to tell what variant you are dealing with.

In general, it consists of plain text interspersed with [[ANSI escape code|ANSI escape sequences]]. There may be [[SAUCE]] data at the end of the file. The text is usually (at least for English language artwork) encoded in [[CP437]]. The characters in the PC BIOS font at code points 1 through 31 are allowed, with some exceptions that are treated as [[C0 controls]] instead: 9 (tab), 10 (LF), 13 (CR), 26 (end of data), 27 (ESC). In the DOS world the behavior implemented in ansi.sys became the de facto standard. This includes some oddities, such as that clear screen also moves the cursor to the upper left corner (most implementations leaves the cursor in place). This is probably also the reason that code points below 32 are considered valid, since they are typed that way in DOS with ansi.sys loaded.

Older ANSI Art files sometimes begin with a "preamble" consisting of Email/Usenet headers, or other plain text metadata or comments. The preamble will be immediately erased by the ANSI codes, so it is invisible when the file is viewed in a normal way.

'''NeoDesk icon''' is an icon format associated with the NeoDesk graphical environment for the Atari ST family of computers, developed by Gribnif Software.

As far as we know, the format has not been decoded. It is reported to be compressed, and "complicated". That said, some .NIC files are clearly uncompressed, so evidently there are multiple .NIC formats.

== Identification ==
There are 3 versions NeoDesk icon files. Version 1 and 2 are uncompressed and have no signature or header. (Since the first icon often depicts a floppy drive which is oblong in it's appearance the top row, consisting of 32 bits, is often empty and thus consisting of zeros.)

Version 1 always have 9 icon, 232 bytes each, a total file size of exactly 2088 bytes.

Version 2 can have any number of icons, 244 bytes each. Thus the file size is a multiple of 244.

Version 3 begin with the ASCII signature "{{magic|.NIC}}".

'''PhotoChrome''' (or PhotoChrome Screen) is a raster image file format used on Atari ST computers. It is associated with the ''PhotoChrome'' image viewer and converter software by Douglas Little. Later versions of PhotoChrome, from version 5, can only encode images and doesn't include a viewer.

== Format ==
Files have a 6-byte fixed header. It is followed by several segments containing the palette and pixel data, which are [[Run-length encoding|RLE-compressed]].

The image dimensions are always 320×200 pixels, but the first row is typically not used (apparently due to hardware limitations), making them effectively 320×199.

Some PhotoChrome files contain two separate images. On an actual Atari ST computer, the viewer would be expected to average them together using temporal dithering, to simulate more colors than the computer could actually display.

== Identification ==
Files start with bytes <code>01 40 00 c8</code> (representing the width and height).

'''Tobias Richter Fullscreen Slideshow''' is a format from the Atari ST.

It was a precursor to the more general purpose format [[PhotoChrome Screen]].
