Free image based software for linux

Image Cluster copies and renames images based on Exif data and file number names. Image Cluster also clusters those images into directories based on a variable sliding window (with a default of 36 hours), which makes it easy to group images based on events without manual intervention.

The inspiration for this program came from recently getting a new Canon SD500 camera to replace my Canon S30 that Id had for years. The upside, the Canon SD500 rocks! The downside, I now have 2 cameras that are burning through the same sequence numbers, so my previous solution of just putting all the files in to directories by the first 2 digits of the sequence numbers was no longer going to work.

Imagecluster solves this problem, plus another grouping problem that Id been thinking about, by extracting the CreateDate and FileNumber exif tags from the images, and using that as the basis of a new filename (typically YYYY:mm:dd_HH:MM:SS_FileNumber.jpg). This ensures that 2 images taken at the same second have an even smaller chance of colliding, as their camera sequence numbers would have to also be the same at that second.

But that is just the first step. I have noticed that I am an occational photographer, so take pictures in bursts, often for a weekend of hanging out with folks, though sometimes for a vacation as well. This got me thinking. What I really needed is a tool that also creates directories that allows for some minimum tollerance between CreateDate, that is used to cluster images. For me, the optimum value seems to be 36 hours, though this is configurable via the command line.

This took me an afternoon to pull together, Im sure it could be smarter, but it is useful enough to post for others to use.

Options:

-d directory
Set the target directory for images. Defaults to /tmp/photos, which is probably not what you want.

-D
Dryrun. Tells you what the program would have done.

-h
Print out help message

-s
Seperator character. It defaults to : (i.e. 2005:10:09...), but is user configurable because my friend Clemens wants to use - (i.e. 2005-10-09) instead.

-t
Set the tollerance for image clustering. This is the maximum time between any 2 pictures in a cluster, which will cause a new cluster to be created. The name of the cluster will be YYYY:MM:DD of the first image in the cluster, even if it spans multiple days. Because this tollerance is the maximum time between any two images in the cluster, it is possible that all images you have ever taken could be in 1 cluster, if you took a picture every day of your life. Hence, this feature isnt useful to everyone. If you are that kind of person, set tollerance to 16 hours or something, and youll tend to get 1 day sized buckets.

-v
Prints verbose output

Image Assistant is a Firefox extension that launches an image in an external viewer, when user selects the context menu item provided, which is titled "Open Image..." and is located under View Image right-click menu item.

This allows for zooming, printing, and other rich functionality not available in the browser.

Resize Image is a service menu which adds the ability to resize an image to a new size.

Requires ImageMagick, KDialog and bash.

Image::Xpm is a Perl module that can load, create, manipulate and save xpm image files.

SYNOPSIS

use Image::Xpm;

my $j = Image::Xpm->new(-file, Camel.xpm);

my $i = Image::Xpm->new(-width => 10, -height => 16);

my $h = $i->new; # Copy of $i

$i->xy(5, 8, red); # Set a colour (& add to palette if necessary)
print $i->xy(9, 3); # Get a colour

$i->xy(120, 130, #1256DD);
$i->xy(120, 130, $i->rgb2colour(66, 0x4D, 31));

$i->vec(24, #808080); # Set a colour using a vector offset
print $i->vec(24); # Get a colour using a vector offset

print $i->get(-width); # Get and set object attributes
$i->set(-height, 15);

$i->load(test.xpm);
$i->save;

# Changing just the palette
$i->add_colours(qw(red green blue #123456 #C0C0C0));
$i->del_colour(blue);

This class module provides basic load, manipulate and save functionality for the xpm file format. It inherits from Image::Base which provides additional manipulation functionality, e.g. new_from_image(). See the Image::Base pod for information on adding your own functionality to all the Image::Base derived classes.

new()
my $i = Image::Xpm->new(-file => test.xpm);
my $j = Image::Xpm->new(-width => 12, -height => 18);
my $k = $i->new;

We can create a new xpm image by reading in a file, or by creating an image from scratch (all the pixels are white by default), or by copying an image object that we created earlier.

If we set -file then all the other arguments are ignored (since theyre taken from the file). If we dont specify a file, -width and -height are mandatory and -cpp will default to 1 unless specified otherwise.

-file

The name of the file to read when creating the image. May contain a full path. This is also the default name used for loading and saveing, though it can be overridden when you load or save.

-width

The width of the image; taken from the file or set when the object is created; read-only.

-height

The height of the image; taken from the file or set when the object is created; read-only.

-cpp

Characters per pixel. Commonly 1 or 2, default is 1 for images created by the module; read-only.

See the example for how to change an images cpp.

-hotx

The x-coord of the images hotspot; taken from the file or set when the object is created. Set to -1 if there is no hotspot.

-hoty

The y-coord of the images hotspot; taken from the file or set when the object is created. Set to -1 if there is no hotspot.

-ncolours

The number of unique colours in the palette. The image may not be using all of them; read-only.

-cindex

An hash whose keys are colour names, e.g. #123456 or blue and whose values are the palette names, e.g. , #, etc; read-only. If you want to add more colours to the image itself simply write pixels with the new colours using xy; if you want to add more colours to the palette without necessarily using them in the image use add_colours.

-palette

A hash whose keys are the palette names, e.g. , #, etc. and whose values are hashes of colour type x colour name pairs, e.g. c => red, etc; read-only. If you want to add more colours to the image itself simply write pixels with the new colours using xy; if you want to add more colours to the palette without necessarily using them in the image use add_colours.

-pixels

A string of palette names which constitutes the data for the image itself; read-only.

-extname

The name of the extension text if any; commonly XPMEXT; read-only.

-extlines

The lines of text of any extensions; read-only.

-comments

An array (possibly empty) of comment lines that were in a file that was read in; they will be written out although we make no guarantee regarding their placement; read-only.
get()

my $width = $i->get(-width);
my ($hotx, $hoty) = $i->get(-hotx, -hoty);

Get any of the objects attributes. Multiple attributes may be requested in a single call.

See xy and vec to get/set colours of the image itself.

set()
$i->set(-hotx => 120, -hoty => 32);

Set any of the objects attributes. Multiple attributes may be set in a single call; some attributes are read-only.

See xy and vec to get/set colours of the image itself.

xy()
$i->xy(4, 11, #123454); # Set the colour at point 4,11
my $v = $i->xy(9, 17); # Get the colour at point 9,17

Get/set colours using x, y coordinates; coordinates start at 0. If the colour does not exist in the palette it will be added automatically.

When called to set the colour the value returned is characters used for that colour in the palette; when called to get the colour the value returned is the colour name, e.g. blue or #f0f0f0, etc, e.g.

$colour = xy($x, $y); # e.g. #123456
$cc = xy($x, $y, $colour); # e.g. !

We dont normally pick up the return value when setting the colour.

vec()
$i->vec(43, 0); # Unset the bit at offset 43
my $v = $i->vec(87); # Get the bit at offset 87

Get/set bits using vector offsets; offsets start at 0. The offset of a pixel is ((y * width * cpp) + (x * cpp)).

The sort of return value depends on whether we are reading (getting) or writing (setting) the colour - see xy for an explanation.

rgb2colour() and rgb2color()
$i->rgb2colour(0xff, 0x40, 0x80); # Returns #ff4080
Image::Xpm->rgb2colour(10, 20, 30); # Returns #0a141e

Convenience class or object methods which accept three integers and return a colour name string.

load()
$i->load;
$i->load(test.xpm);

Load the image whose name is given, or if none is given load the image whose name is in the -file attribute.

save()
$i->save;
$i->save(test.xpm);

Save the image using the name given, or if none is given save the image using the name in the -file attribute. The image is saved in xpm format.

add_colours() and add_colors()
$i->add_colours(qw(#C0C0DD red blue #123456));

These are for adding colours to the palette; you dont need to use them to set a pixels colour - use xy for that.

Add one or more colour names either as hex strings or as literal colour names. These are always added as type c colours; duplicates are ignored.

NB If you just want to set some pixels in colours that may not be in the palette, simply do so using xy since new colours are added automatically.

del_colour() and del_color()
$i->del_colour(green);

Delete a colour from the palette; returns undef if the colour isnt in the palette, false (0) if the colour is in the palette but also in the image, or true (1) if the colour has been deleted (i.e. it was in the palette but not in use in the image).

Imagero Reader is a Java library for reading image files. Supported file types include BMP, GIF, TIFF, PNG, JNG, MNG, JPEG (including 12-bit grey), PSD, PBM, PGM, PPM, TGA, EPS, EPSI, and EPSF.
The following RAW file types are also supported, at least partially: MRW, CRW, NEF, DCR, and DNG. It can read thumbnails, read metadata (IPTC, EXIF, and XMP), edit metadata, get image width and height, get the number of images contained in a file, define an area to read, add a ProgressListener, choose an image channel to read, set a scale factor, set subsampling (JPEG only), and read an image (or channel) directly into an array.
Supported file types are:
- BMP 1, 4, 8, 16, 24 and 32 bit uncompressed; 4 and 8 bit compressed
- GIF
- TIFF 1, 4, 8, 16, 32, 48 and 64 bit per pixel; bilevel, grayscale, palette, RGB, CMYC, Cie Lab, YCrCb color spaces; CCIT1D, G3, G4, ZIP, JPEG, LZW and PackBits compression
- PNG, JNG, MNG
- JPEG inclusive CMYC and 12-bit grey
- PSD
- PBM, PGM, PPM
- TGA
- read embedded images from EPS, EPSI, EPSF
Supported RAW files:
- MRW
- CRW*, CR2*, THM
- NEF*
- DCR*
- DNG*
- Full resolution image cant be yet read, but thumbnail, preview and metadata can be read.
Main features:
- read thumbnails
- read/edit metadata
- any metadata contained in ImageResourceBlock ( PSD, JPEG, TIFF) and ImageFileDirectrory entry ( TIFF, NEF, DNG, DCR) can be edited full control over JPEG metadata
- get image width and height
- get number of images, contained in file
- define an area to read
- add a ProgressListener
- estimate JPEG compression/quality
- read an image channel
- set a scale factor
- set subsampling (JPEG only)
- read an image (or channel) directly into an array
- easy IPTC handling with IPTCParser and IPTCEditor
Whats New in 1.9.6 Stable Release:
- The EPS parser was partially rewritten and made more generic and easy to use.
- It may be used now to parse nearly every kind of data (as a programmable parser).
- Thumbnails are read from AI (Illustrator) files.
- Disc based image caching was implemented (but is beta).
- New methods were added to TiffUtils: insert IFDEntry, remove IFDEntry, and create and insert IFDEntry with IPTC data.
- Two utility classes were added for creating and adding EXIF and GPS data to TIFF images.
- An important bug in XMPApp1 concerning wrong field length was fixed.
Whats New in 2.0.0 RC3 Development Release:
- It is possible to write TIFF images now. TiffWriter can currently write RGB, ARGB, CMYK, and grayscale (8 bit) images.
- Supported compression schemes are uncompressed, PackBits, and ZIP.
- Bugfixes were made.

Prima::image-load is a Perl module using image subsystem.

Simple loading

Simplest case, loading a single image would look like:

my $x = Prima::Image-> load( filename.duf);
die "$@" unless $x;

Image functions can work being either invoked from package, or from existing Prima::Image object, in latter case the caller object itself is changing. The code above could be also written as

my $x = Prima::Image-> create;
die "$@" unless $x-> load( filename.duf);

In both cases $x contains image data upon success. Error is returned into $@ variable ( see perldoc perlvar for more info).
