NAME¶
Apache::Gallery - mod_perl handler to create an image gallery
SYNOPSIS¶
See the INSTALL file in the distribution for installation instructions.
DESCRIPTION¶
Apache::Gallery creates an thumbnail index of each directory and allows viewing
pictures in different resolutions. Pictures are resized on the fly and cached.
The gallery can be configured and customized in many ways and a custom
copyright image can be added to all the images without modifying the original.
CONFIGURATION¶
In your httpd.conf you set the global options for the gallery. You can also
override each of the options in .htaccess files in your gallery directories.
The options are set in the httpd.conf/.htaccess file using the syntax:
PerlSetVar OptionName 'value'
Example:
PerlSetVar GalleryCacheDir '/var/cache/www/'
- GalleryAutoRotate
- Some cameras, like the Canon G3, can detect the orientation of a the
pictures you take and will save this information in the 'Orientation' EXIF
field. Apache::Gallery will then automatically rotate your images.
This behavior is default but can be disabled by setting GalleryAutoRotate to
0.
- GalleryCacheDir
- Directory where Apache::Gallery should create its cache with scaled
pictures. The default is /var/cache/www/ . Here, a directory for each
virtualhost or location will be created automatically. Make sure your
webserver has write access to the CacheDir.
- GalleryTemplateDir
- Full path to the directory where you placed the templates. This option can
be used both in your global configuration and in .htaccess files, this way
you can have different layouts in different parts of your gallery.
No default value, this option is required.
- GalleryInfo
- With this option you can define which EXIF information you would like to
present from the image. The format is: '<MyName => KeyInEXIF,
MyOtherName => OtherKeyInEXIF'
Examples of keys: ShutterSpeedValue, ApertureValue,
SubjectDistance, and Camera
You can view all the keys from the EXIF header using this perl-oneliner:
perl "-e" 'use Data::Dumper; use Image::Info qw(image_info); print
Dumper(image_info(shift));' filename.jpg
Default is: 'Picture Taken => DateTimeOriginal, Flash => Flash'
- GallerySizes
- Defines which widths images can be scaled to. Images cannot be scaled to
other widths than the ones you define with this option.
The default is '640 800 1024 1600'
- GalleryThumbnailSize
- Defines the width and height of the thumbnail images.
Defaults to '100x75'
- GalleryThumbnailSizeLS
- If set to '1', GalleryThumbnailSize is the long and the short side
of the thumbnail image instead of the width and height.
Defaults to '0'.
- GalleryCopyrightImage
- Image you want to blend into your images in the lower right corner. This
could be a transparent png saying "copyright my name 2001".
Optional.
- GalleryWrapNavigation
- Make the navigation in the picture view wrap around (So Next at the end
displays the first picture, etc.)
Set to 1 or 0, default is 0
- GalleryAllowOriginal
- Allow the user to download the Original picture without resizing or
putting the CopyrightImage on it.
Set to 1 or 0, default is 0
- GallerySlideshowIntervals
- With this option you can configure which intervals can be selected for a
slideshow. The default is '3 5 10 15 30'
- GallerySortBy
- Instead of the default filename ordering you can sort by any stat
attribute. For example size, atime, mtime, ctime.
- GalleryDirSortBy
- Set this variable to sort directories differently than other items, can be
set to size, atime, mtime and ctime; setting any other value will revert
to sorting by name.
- GalleryMemoize
- Cache EXIF data using Memoize - this will make Apache::Gallery faster when
many people access the same images, but it will also cache EXIF data until
the current Apache child dies.
- GalleryUseFileDate
- Set this option to 1 to make A::G show the files timestamp instead of the
EXIF value for "Picture taken".
- GallerySelectionMode
- Enable the selection mode. Select images with checkboxes and get a list of
filenames.
- GalleryEXIFMode
- You can choose how Apache::Gallery should display EXIF info from your
images.
The default setting is 'namevalue'. This setting will make Apache::Gallery
print out the names and values of the EXIF values you configure with
GalleryInfo. The information will be parsed into $INFO in pictureinfo.tpl.
You can also set it to 'values' which will make A::G parse the configured
values into the var $EXIFVALUES as 'value | value | value'
If you set this option to 'variables' the items you configure in GalleryInfo
will be available to your templates as $EXIF_<KEYNAME> (in all
uppercase). That means that with the default setting "Picture Taken
=> DateTimeOriginal, Flash => Flash" you will have the
variables $EXIF_DATETIMEORIGINAL and $EXIF_FLASH available to your
templates. You can place them anywhere you want.
- GalleryRootPath
- Change the location of gallery root. The default is ""
- GalleryRootText
- Change the name that appears as the root element in the menu. The default
is "root:"
- GalleryMaxThumbnailsPerPage
- This options controls how many thumbnails should be displayed in a page.
It requires $BROWSELINKS to be in the index.tpl template file.
- GalleryImgFile
- Pattern matching the files you want Apache::Gallery to view in the index
as thumbnails.
The default is '\.(jpe?g|png|tiff?|ppm)$'
- GalleryDocFile
- Pattern matching the files you want Apache::Gallery to view in the index
as normal files. All other filetypes will still be served by
Apache::Gallery but are not visible in the index.
The default is
'\.(mpe?g|avi|mov|asf|wmv|doc|mp3|mp4
|ogg|pdf|rtf|wav|dlt|txt|html?|csv|eps)$'
- GalleryTTFDir
- To use the GalleryCopyrightText feature you must set this option to the
directory where your True Type fonts are stored. No default is set.
Example:
PerlSetVar GalleryTTFDir '/usr/share/fonts/'
- GalleryTTFFile
- To use the GalleryCopyrightText feature this option must be set to the
name of the True Type font you wish to use. Example:
PerlSetVar GalleryTTFFile 'verdanab.ttf'
- GalleryTTFSize
- Configure the size of the CopyrightText that will be inserted as copyright
notice in the corner of your pictures.
Example:
PerlSetVar GalleryTTFSize '10'
- GalleryCopyrightText
- The text that will be inserted as copyright notice.
Example:
PerlSetVar GalleryCopyrightText '(c) Michael Legart'
- GalleryCopyrightColor
- The text color of your copyright notice.
Examples:
White:
PerlSetVar GalleryCopyrightColor '255,255,255,255'
Black:
PerlSetVar GalleryCopyrightColor '0,0,0,255'
Red:
PerlSetVar GalleryCopyrightColor '255,0,0,255'
Green:
PerlSetVar GalleryCopyrightColor '0,255,0,255'
Blue:
PerlSetVar GalleryCopyrightColor '0,0,255,255'
Transparent orange:
PerlSetVar GalleryCopyrightColor '255,127,0,127'
- GalleryCopyrightBackgroundColor
- The background-color of a GalleryCopyrightText
r,g,b,a - for examples, see GalleryCopyrightColor
- GalleryQuality
- The quality (1-100) of scaled images
This setting affects the quality of the scaled images. Set this to a low
number to reduce the size of the scaled images. Remember to clear out your
cache if you change this setting. Quality seems to default to 75, at least
in the jpeg and png loader code in Imlib2 1.1.0.
Examples:
Quality at 50:
PerlSetVar GalleryQuality '50'
- GalleryUnderscoresToSpaces
- Set this option to 1 to convert underscores to spaces in the listing of
directory and file names, as well as in the alt attribute for HTML
<img> tags.
- GalleryCommentExifKey
- Set this option to e.g. ImageDescription to use this field as comments for
images.
- GalleryEnableMediaRss
- Set this option to 1 to enable generation of a media RSS feed. This can be
used e.g. together with the PicLens plugin from http://piclens.com
FEATURES¶
- Rotate images
- Some cameras, like the Canon G3, detects the orientation of a picture and
adds this info to the EXIF header. Apache::Gallery detects this and
automatically rotates images with this info.
If your camera does not support this, you can rotate the images manually,
This can also be used to override the rotate information from a camera
that supports that. You can also disable this behavior with the
GalleryAutoRotate option.
To use this functionality you have to create file with the name of the
picture you want rotated appended with ".rotate". The file
should include a number where these numbers are supported:
"1", rotates clockwise by 90 degree
"2", rotates clockwise by 180 degrees
"3", rotates clockwise by 270 degrees
So if we want to rotate "Picture1234.jpg" 90 degrees clockwise we
would create a file in the same directory called
"Picture1234.jpg.rotate" with the number 1 inside of it.
- Ignore directories/files
- To ignore a directory or a file (of any kind, not only images) you create
a <directory|file>.ignore file.
- Comments
- To include comments for a directory you create a <directory>.comment
file where the first line can contain "TITLE: New title" which
will be the title of the page, and a comment on the following lines. To
include comments for each picture you create files called
picture.jpg.comment where the first line can contain "TITLE: New
title" which will be the title of the page, and a comment on the
following lines.
Example:
TITLE: This is the new title of the page
And this is the comment.<br />
And this is line two of the comment.
The visible name of the folder is by default identical to the name of the
folder, but can be changed by creating a file <directory>.folder
with the visible name of the folder.
It is also possible to set GalleryCommentExifKey to the name of an EXIF
field containing the comment, e.g. ImageDescription. The EXIF comment is
overridden by the .comment file if it exists.
