Free image viewers software for linux

image-viewer is a very simple Kommander script. But written following one of the 2-3 tutorials you can find on the net. Included in tarball you can find this guide to introduce in Kommander GUI. The site is: http://applications.linux.com/article.pl?sid=04/12/17/2033227&tid=49 and was written in 2004 by Michał Kosmulski

I know people want to use this great program..but documentations are very poor...this example helps people who wants to learn something about simple array, combobox, label and connections between signals and slots..very very important.

So, i hope the guide and the example will be usefull.

QVV is image viewer based on TrollTechs Qt Toolkit! QVV is small, simple, handy ( last one is IMO ). However the sources are there -- you can come up with your own opinion.

NOTE: QVV 0.16 AND LATER VERSIONS REQUIRE QT 3.x!

QVV allows you to browse directories with lynx-like interface, view images browse next/prev image while showing image window or in the directory list, multiple image windows and directory browsers can be opened/closed with a single key, panning easy with arrow keys or mouse and few other things as well.

QVV is only few hundred lines of source code and handles as much file formats as Qt does -- JPEG (all sorts of jpegs that jpeglib supports), PNG, GIF, XPM and more..

Quick Image Viewer (qiv) is a very small and fast GDK/Imlib image viewer designed to replace the classic image viewers like xv or xloadimage. Quick Image Viewer program runs on FreeBSD, Linux (libc5/glibc), Solaris (SunOS) and HP-UX.
Main features:
- moving & zooming image in fullscreen mode.
- setting image as x11 background (centered,tiled,stretched..) with user settable background color
- fullscreen viewing with a great statusbar
- external "qiv-command" program support
- screensaver mode
- brightness/contrast/gamma correction
- real transparency
- maxpect (zoom to screen size while preserving aspect ratio)
- scale_down (scale down to big images to fit screen size)
- slideshow (with random order if you want)
- filename filer
- flip horizontal/vertical, rotate left/right
- delete function (move to .qiv-trash/)
- jump to image number x, jump forward/backward x images
Enhancements:
- This release has some bugfixes and new options.

Image Magazine provides a content type which acts both as a folder and as an image.
You populate it with 2 to 4 images, and optionnaly select a layout.
Options include width, background color, padding and margin, and layout mode.
ImageMag then merges the images into a layout while keeping the aspect ratios.
You can then use and call your ImageMag as a standard ploneImage, this mean you can :
.use instance/image_thumbnail, instance/image_large, and so on suffixes to call its different sizes
.call it directly from kupu to illustrate your articles (see readme.txt)
Works with:
- Plone 2.5.2
- Plone 2.5.1
- Plone 2.5

While Digikam is a great app for managing your images, it lacks a good and fast image viewer in my opinion. Unfortunately, the fastest image viewer for KDE, Kuickshow, is not available as KIPI plugin. Therefore I wrote this plugin to fill that gap
Main features:
- works as KIPI plugin
- fast image loading (about as fast as kuickshow)
- fast zooming/panning (faster than kuickshow)

PyQGLViewer is a set of Python bindings for the libQGLViewer C++ library. PyQGLViewer extends the Qt framework with widgets and tools that eases the creation of OpenGL 3D viewers.

Gwenview is a fast and easy to use image viewer and browser for KDE.
All common image formats are supported, such as PNG (including transparency), JPEG (including EXIF tags and lossless transformations), GIF (images as well as animations), XCF (Gimp image format), BMP, XPM and others.
Standard features include slideshow, fullscreen view, image thumbnails, dragndrop, image zoom, full network transparency using the KIO framework, including basic file operations and browsing in compressed archives, non-blocking GUI with adjustable views.
Gwenview also provides image and directory KParts components for use e.g. in Konqueror.
Additional features, such as image renaming, comparing, converting, batch processing, HTML gallery and others are provided by the KIPI image framework.
Main features:
Image viewing
- Gwenview can load and save all image formats supported by KDE, but Gwenview can also browse GIMP files (*.xcf) thanks to the included QXCFI component developed by
- Lignum Computing.
- It correctly displays images with alpha channel, using the traditionnal checker board as a background to reveal transparency.
- Gwenview let you accurately control the way images are scaled: you can zoom in and out or automatically scale the image to fit the window. You can also lock the zoom factor to keep the same zoom between images.
- When browsing JPEG images with EXIF information, Gwenview automatically rotates them according to the EXIF Orientation tag.
- It can show image properties and image specific meta-information like Konqueror does.
- Since version 1.1.8, Gwenview knows how to show animated images like MNG or GIF.
Image manipulations
- Gwenview does not try to replace your favorite image editor, so it only features the most simple image manipulations: rotation and mirroring. If JPEGTran is installed, Gwenview will perform lossless manipulations. For more complex image manipulations, you can start any external tools from Gwenview. You can define your very own selection of tools to fit your needs.
Browsing your collections of images
- Gwenview features the necessary file management operations: copy, move, delete, rename and dragn drop images. It has full support for KIO slaves: you can browse FTP/Windows shares, go into tar balls or zip files.
- Depending on your needs and on the type of images you are browsing, you can choose to use a detailed file view or the thumbnail view, which features three easily accessible thumbnail sizes.
- The keyboard browsing allow you to go from one image to another without loading all the images between them.
- Reach your collection folders fast with the folder bookmarks. The bookmarks are shared with Konsole and KDE file dialogs.
Presenting your images
- The fullscreen with optional overlayed image file and the simple built-in slide show allows you to present images the way you want them to show.
The interface
- Gwenview features a folder tree window and a file list window to provide easy navigation among your thousand images.
- It uses docked windows, so you can alter the layout in any way you want. You can also browse your images in full screen.

Image::BMP is a bitmap parser/viewer.
SYNOPSIS
use Image::BMP;
# Example one:
my $img = new Image::BMP(
file => some.bmp,
debug => 1,
);
$img->view_ascii;
# Example two:
my $img2 = new Image::BMP;
$img2->open_file(another.bmp);
my $color = $img2->xy(100,100); # Get pixel at 100,100
my ($r,$g,$b) = $img2->xy_rgb(100,200);
Image::BMP objects can parse and even ascii view bitmaps of the .BMP format. It can read most of the common forms of this format.
It can be used to:
Just get image info, dont read the whole image:
my $img = new Image::BMP(file => some.bmp);
print "Resolution: $img->{Width} x $img->{Height}n";
View images
(See C< SYNOPSIS > example one)
Read images and poke at pixels
(See C< SYNOPSIS > example two)
Parse through all pixel data
(See C< ADD_PIXEL > below)
It does not currently write bmap data, simply because I didnt have a use for that yet. Convince me and Ill add it.
Version restrictions:
4-bit RLE compression
- I havent seen an image like this yet, it wouldnt be hard to add.
bitfields compression
- I dont even know what that is..
RLE delta compression
- This isnt tested yet - I havent seen an image that uses this portion of RLE compression, so it currently does what I think is right and then prints a message asking you to send me the image/results.
