PictView Multi-format image viewer and converter in a small package.
* * * * *
[added 1997, updated 2000-07-20]
Relatively small (147K), fast, versatile, and configurable. This program packs both image viewing and format conversion functions into an efficiently coded program.From the docs:
PictureViewer is a mouse-driven viewer and converter of images. It runs on all EGA, VGA, SuperVGA and Extended-VGA video adapters. PictureViewer is able to read images stored in approximately 40 graphics file formats (140 versions) and convert them into another format. All functions are extremely fast, up to 10 times faster than other programs.
Other features: Optional command-line loading of images; fit image to screen, hi and low quality JPEG decompression (including progressive JPEGs); animated GIFs, display adapter and screen resolution options; configuration.
Notes: No slideshow or image preview options. Requires 80386+, EGA+, 300+ KB RAM. XMS recommended.Supported formats (see formats.doc for format-specific read / write capabilities and restrictions):

LxPic Tiny, portable JPG, BMP, GIF viewer with big features.
* * * * *
[added 1997, updated 2003-01-20]
LxPic was not designed for PCs equipped with the latest quantum warp accelerated 3D graphics cards. Instead, LxPic is suitable for nearly any PC running DOS from the lowliest 8088, B/W laptops and palmtops, to the latest desktops. It is the most "portable" graphics viewer listed here. With a 19.5K (!) binary and 64K mem requirement, disk and memory needs shouldn't be issues for users. CGA and DOS 2.11 or better are required. The program and its author get five stars just for this feat of programming.Quick feature list...

ShowJPG Fast and small command line JPEG viewer.
* * * * *
[updated 2003-02-13]This small app fills a big void...
Usage: ShowJPG File_name [Width] [-q] [-l] [-c] [-dTime] [-tTime] [-e] [-k] File_name may be memory address in the form :SSSSOOOO where SSSS is the segment and OOOO is the offset part, both hexadecimal. Width is a number specifying the width in pixels of the graphics mode that ShowJPG will use to display the image. Any graphics mode with this width must be supported by the video adapter and must be HiColor or TrueColor for color images and must be 256-color for black-and-white images. -Q or -q commands ShowJPG to read the image by a slower method, but preserving high quality of the image. -L or -l enables exiting ShowJPG with left mouse button. -C or -c clears the screen under Windows95. -D or -d delays Time milliseconds under Windows95. -T or -t ShowJPG exits after Time milliseconds. -E or -e ShowJPG exits immediately without clearing screen. -K or -k keeps the screen unchanged before decompressing. Use + and - keys to zoom-in and zoom-out the image. Use arrow keys and a mouse to scroll.

PixView JPG, GIF, and BMP image viewer with slideshow.
* * * * (v2.2).
PixView is a good 32-bit JPG, GIF, and BMP image viewer and is comparable to the popular shareware product QPV in speed, navigation and display capabilities. The directory listing screen is easy to navigate with a mouse. PixView requires 80386+ PC and a VESA driver to display images at resolutions other than 320X220X256 color/gray (no driver support for graphics cards). Includes zoom and slideshow features but no image preview. Built-in configuration, but PixView doesn't save some settings (e.g., default file masks). One shortcoming of the freeware version is the inability to load files on the command line (the shareware version allows this, has true color support, load-while-display feature for slide show, and optimized compilation). Although the docs say there is no GIF89 support, I've successfully loaded GIF87, 89, and 89-interlaced images. Supports progressive JPGs. 32-bit DJGPP build, requires 80386+ and a DOS Protected Mode Interface (CWSDPMI, [included] or other). Supports LFNs under Win9x.
Bugs (?): I haven't used the v2.3 extensively, but it has locked my system a couple times and not all mouse functions seem to work in viewing mode (e.g., r-button exit). Never a problem with previous versions. Still doesn't seem to save file masks.

LWhiz Command line image viewer for JPEG, GIF and other formats.
* * * *
This is a good helper app for file managers. Coded in assembly language: fast and small (exe is 33K).
Supported formats: JPEG, GIF, TIF, PCX, TGA, PNM, WPG, LBM, ICO, BMP and PhotoCD ( 768x512 ). Analyzes signatures of files when loading (not file extensions): format detection is more reliable. Allows viewing images up to a resolution of 1280x1024 in TrueColor. "Screen Magnifying-Glass" magnifies a large square area around mouse pointer a smart idea for systems that lack the memory to show zoomed full images. Can magnify this area by several powers using the "
+" key. No directory browser load files from the command line. Slideshow capable.
Requires: 80386+, 2MB RAM; VESA compatibility; 1MB+ video memory.

OMBRA Fast GIF, TGA, PCX, BMP, RAW image viewer, more.
* * * *
Ombra is a fast 32-bit viewer that stands out among the crowd because it supports real time zooming with a mouse as well as real time cycling of brightness, contrast, hue, saturation, rgb, and other effects. Although Pentium-optimized this program is quick even on an old 386. Effects, image resolution, and other commands are accessed from semi-transparent drop-down menus. Files are loaded from the command line: OMBRA makes a good helper app for file managers. Requires 80386+, VESA compatibility highly recommended.
The current release supports the following image formats:
Reads GIF (87a, 89a +interlaced), TGA (8 to 32 bit, uncompressed), PCX (2-color up to true-color), BMP (1-, 4-, 8-, 24-bit; raw, rle4 and rle8); Read and writes to HSI RAW format (note: Display can convert RAW to other formats).

Display Image viewing and conversion package.
* * * *
Display is a robust 32-bit image viewing and conversion package. Display is not small a full installation chews up about one MB of disk space (but some files can be deleted see the FAQ). Supported image and movie formats include
BMP, RLE, TIF, GIF, JPG, TGA, ICO, PCX, AVI, MPEG, MOV, GL, DL, FLI, and, uniquely, several less common image formats. Progressive JPEGs are supported. In addition, text file viewing is supported (ANSI files) as is UUE and MIME en/decoding, and
WAV, AU playing. The interface is generally clean and is mouse compatible (under DOS only).
The principle drawback of Display is its slow dithering of true color images compared to other viewing packages here, although even this can be tweaked by adjusting dithering settings. The latest AVI movie standards (interlaced) and some MOV formats are not supported in v.189. Setup may be a challenge for some.

QPNG/386 PNG and TGA image viewer.
* * * * *
QPNG/386, which is a special freeware version of the famous shareware QPV/386, reads only the PiNG (PNG) and Targa (TGA) formats. Preview Image, Zoom and Slideshow options are available as are basic file management commands. The smartly designed interface is identical to QPV's. For PNG files, QPNG supports all bit depths (1 to 16 bits/sample), background transparency, interlacing, and gamma correction. Driver support for some video cards, but VESA recommended (use the VESA2CFG utility to create a VESA CFG file).

JPEG Command-line image format conversion utilities.
* * * *
JPEG is a speedy command-line conversion utility, designed to process and output full color, 24-bit images. Lower resolution images can be smoothed, but might not look very good. Each package contains two main executables, CJPEG for converting images to JPEG format, and DJPEG for converting JPEG files to GIF, BMP, TGA, or PBM format. Also included are a tool that converts between JPEG types, and text processors. Progressive JPEG format is supported. Many options are included: compression quality, smoothing, dithering, scaling, and advanced options like quantization and color mapping. This is a great utility for performing batch conversions and is optimized for 80386 or better machines (but a 16-bit, 80286 version is available). The JPEG bundle does not include an image viewer. Runs under DOS3.0+, and in a Windows or OS/2 DOS box.
80386 versions are 32-bit DJGPP builds that require a DOS Protected Mode Interface (provided by CWSDPMI or an OS). They run 25-50% faster than the 16-bit 80286 versions.
Author: Independent JPEG Group (1998).
Legal issues. Notable in v6b is the removal or modification of GIF related features because of GIF patent considerations. From the docs:
The IJG distribution formerly included code to read and write GIF files. To avoid entanglement with the Unisys LZW patent, GIF reading support has been removed altogether, and the GIF writer has been simplified to produce "uncompressed GIFs". This technique does not use the LZW algorithm; the resulting GIF files are larger than usual, but are readable by all standard GIF decoders.However, Unisys has issued this statement (2005):
Unisys U.S. LZW Patent No. 4,558,302 expired on June 20, 2003, the counterpart patents in the United Kingdom, France, Germany and Italy expired on June 18, 2004, the Japanese counterpart patents expired on June 20, 2004 and the counterpart Canadian patent expired on July 7, 2004.
So if you want to create compressed GIFs, it appears that use of v6a is legal. Or if you already have v6a, there is no need to replace it with v6b. We offer links to v6b because its download package (80386 version) is smaller than v6a's, source is available, and for formats other than GIF it's the same as v6a.

NConvert Multi-format image converter / viewer package.
* * * * 1/2
[added 1999-01-08, updated 2005-04-20]
This suite of 32-bit DOS image viewing and conversion programs may be too large and tedious for the casual user, but it possesses several unique and favorable characteristics:
NConvert is the command line converter which includes several advanced image manipulation options. The included viewers (NView, View2) read the same formats as NConvert and while adequate for basic viewing, are comparatively large (550K+) for their lack of features. NVIEW is the command line viewer while VIEW2 incorporates a directory browser with slideshow capability. Neither includes mouse support.
Special requirements: 80386+, math coprocessor (80387 FPU, or 80486+ CPU), DOS/4GW extender (included). VESA compatible video recommended. The View2 interface language is French; the docs and companion programs are available in English although some program output is in French. Special Notes: You may need to manually execute the DOS extender DOS/4GW on the command line (using the program name, options, and file as parameters).

[added 2001-11-11, updated 2004-06-13]From the docs:
Pngcrush is an optimizer for PNG (Portable Network Graphics) files. It can be run from a commandline in an MSDOS window, or from a UNIX or LINUX commandline. Its main purpose is to reduce the size of the PNG IDAT datastream by trying various compression levels an PNG filter methods. It also can be used to remove unwanted ancillary chunks, or to add certain chunks including gAMA, tRNS, iCCP, and textual chunks.usage: pngcrush [options] infile.png outfile.png pngcrush -e ext [other options] files.png ... pngcrush -d dir [other options] files.png ... options: -already already_crushed_size [e.g., 8192] -bit_depth depth (bit_depth to use in output file) -brute (Use brute-force, try 114 different methods [11-124]) -c color_type of output file [0, 2, 4, or 6] -d directory_name (where output files will go) -double_gamma (used for fixing gamma in PhotoShop 5.0/5.02 files) -e extension (used for creating output filename) -f user_filter [0-5] -fix (fix otherwise fatal conditions such as bad CRCs) -force (Write a new output file even if larger than input) -g gamma (float or fixed*100000, e.g., 0.45455 or 45455) -iccp length "Profile Name" iccp_file -itxt b[efore_IDAT]|a[fter_IDAT] "keyword" "text" -l zlib_compression_level [0-9] -loco ("loco crush" truecolor PNGs) -m method [0 through 200] -max maximum_IDAT_size [default 8192] -nofilecheck (do not check for infile.png == outfile.png) -n (no save; does not do compression or write output PNG) -plte_len n (truncate PLTE) -q (quiet) -reduce (do lossless color type or bit depth reduction) -rem chunkname (or "alla" or "allb") -replace_gamma gamma (float or fixed*100000) even if gAMA is present. -res dpi -save (keep all copy-unsafe chunks) -srgb [0, 1, 2, or 3] -text b[efore_IDAT]|a[fter_IDAT] "keyword" "text" -trns_array n trns trns .. trns[n-1] -trns index red green blue gray -v (display more detailed information) -version (display the pngcrush version) -w compression_window_size [32, 16, 8, 4, 2, 1, 512] -z zlib_strategy [0, 1, or 2] -zmem zlib_compression_mem_level [1-9, default 9] -zitxt b[efore_IDAT]|a[fter_IDAT] "keyword" "text" -ztxt b[efore_IDAT]|a[fter_IDAT] "keyword" "text" -h (help and legal notices) -p (pause)

[added 1997-11, updated 2005-04-20]
Good freeware paint programs for DOS are rare. GrafX2 is a nice 256-color painter supporting 60 resolutions that underwent several cycles of beta development before the original authors ended their effort. If you rely on Windows Paintbrush for drawing, you should try this much superior alternative. GrafX2 is missing some important features (no add text tool). Docs in French & English.

IMPROCES 256-color image processor / bitmap paint program.
[added 1999-06-19, updated 2005-06-05]
While this image processor and bitmap painter hasn't been updated in years, it remains an excellent choice as a DOS paint program, especially if you own an older PC (runs great on my 386/20 laptop).
Requirements: DOS 3.0+, MS-compatible mouse, 512K RAM (XMS/EMS can be used), 80286+ CPU. An FPU will also be utilized if it is found. Most users will need VESA video compatibility and 64K-1MB video memory; there is some dedicated video card support (c. 1993).
Formerly shareware, now freeware. Registered and unregistered program operation are the same, except for "nag" screens that pop up until the program is registered. To register: Place IMREG.KEY in the program directory. Thanks to Greg Head for providing the key file.

OGE (Orfelyusuv Graficky Editor) 256-color bitmap painting program.
This program has an English interface but the docs are in Czech. Seems best suited to older PCs (80286+) with VGA support. OGE's simple interface belies a surprisingly rich program underneath. But with the absence of English documentation, OGE may require exploration by the user to discover many features lurking within the remarkably small (58K) binary. Source code available, under GNU General Public License.
A quick and incomplete summary of features discovered while testing the program:
Quick hints: OGE relies on mouse button 2 for finishing many tasks initiated with mouse button 1 (e.g., to complete object and selection drawing, pop-up menus...). Double clicking on certain toolbar icons allows setting of custom parameters (spray can speed, fill pattern, ...). Manipulate selected areas (flip, rotate, ...) using the mouse button 2 pop-up menu. ESC displays full screen picture.
Requirements: 80286+ PC, VGA, mouse. Has the Borland Pascal 7 CRT bug see TSR runtime fixes.

ANSI drawing programs are most commonly used for creating archive comments and FILE_ID.DIZ files destined for BBSes. The home user could use this program to make logos or more colorful batch files. This program implements a standard mouse and menu driven, text mode interface and is very easy to use. An undocumented (?) feature is multiple undo support. An included program can convert ANSI files to executables which offer faster display. Nice sample drawings included. EXE size = 190K.Features:

|RAY TRACING AND FRACTALS|
POV-Ray (Persistence of Vision Raytracer) Ray tracing application.
* * * * *
POV-Ray is a freeware ray tracing application and is the product of several years of continuous development by the POV-Ray team of independent programmers. POV-Ray represents a remarkable achievement in programming and is a professional application. With the release of Win 32s/Win9x versions of POV-Ray, the DOS version finally steps into the background because of the limitations of the DOS environment. If you're unfamiliar with ray tracing see POV-Ray: Documentation for a good introduction to ray tracing theory, sample images, and version histories. A whole industry of specialized supporting utilities has blossomed over the last few years many are freeware.

PhotoRec Recover lost images from digital camera memory.
[added 2006-08-21]From the docs:
PhotoRec is file data recovery software designed to recover lost pictures or lost files from digital camera memory (CompactFlash, Memory Stick, SecureDigital, SmartMedia, Microdrive, MMC, USB Memory Drives...), even Hard Disks and CDRom.
PhotoRec is safe to use, it will never attempt to write to the drive or memory support you are about to recover from. Recovered files are instead written in the directory from where you are running the PhotoRec program.
Photorec ignores the filesystem, this way it works even if the filesystem is severely damaged. It can recover lost files at least from FAT, NTFS, EXT2/EXT3 filesystem.
PhotoRec has been successfully tested with
- Canon EOS300D, 10D
- HP PhotoSmart 620, 850, 935
- Nikon CoolPix 775, 5700
- Olympus C350N, C860L, Mju 400 Digital, Stylus 300
- Sony DSC-P9
- Praktica DCZ-3.4
- Casio Exilim EX-Z 750
Other notes: Recognizes hundreds of archive, image, video and other file types. Runs under DOS 6.x, FreeDOS, Win9x box. 32-bit DJGPP build, requires 80386+ and a DOS Protected Mode Interface (provided by CWSDPMI [included] or the OS). Open Source under GNU Public License. Package also includes TestDisk.

CAMWORK Download images from digital cameras.
[added 1998-07-20]From the docs:
CamWork is a DOS program designed to extract pictures from the Agfa ePhoto and Olympus digital cameras. It has been tested successfully (as far as I know) with the Agfa 307, 1280, Epson 500, Epson 600, Olympus 200, Olympus 300 cameras...The program names images image01.jpg, image 02.jpg, etc. While the images are downloading the program displays session statistics, including elapsed time, time remaining, percent completed, images remaining, etc. Where possible, CamWork also displays the total number of pictures taken since the camera was created.
CamWork is now EMailWare -- If you like it, send me an E-Mail.
