# What does it do?:
# ##############

Multifunction Image Handler PHP Script
This script is a very easy to use multifunction image handler script
for your weather web site. The caching feature makes it the perfect
solution to gracefully "hot link" an image from another web site.

Some of the many features include:
    * Supports .jpg .gif and .png, download an image, cache the image,
    display the image
    * Supports remote images or local images on your web server
    * Convert the image type(optional)
    * Crop the image(optional)
    * Resize the image(optional)
    * Resize the image preserving aspect ratio(optional)
    * Jpeg compression(optional)
    * Annotate text on the image, add up to 3 text overlays(optional)
    * Multi line text support(optional)
    * Text alignment options(optional)
    * Text margin options(optional)
    * Text color options(optional)
    * Auto archive/rotate images with or without thumbs,
    this feature can be utilized for web cam image archiving(optional)
    * Outputs most errors as an image with error code.

################
# Why use it:
# ##############

Reduces bandwidth consumption that can annoy webmasters:
Even when you have permission to "hot link" to another site's image,
if your site generates too many requests for the image, they may get
annoyed and tell you to stop.
This script will considerably lighten the bandwidth consumption load.
Make thumbnail size images from larger ones: I use this script to make
a thumbnail image of of my web cam image for a link on my main page,
it even puts the words "Live Cam" on it.
See sample here:
http://www.642weather.com/weather/image-webcam-thumb.php
.. and it offers many other optional desirable features mentioned
in the "What does it do" section above.
Can also be used to output an image with web cam text overlay with up to 3
different overlay areas
Live Demo: http://www.642weather.com/weather/scripts-image-handler.php#IHdemo

################
# How to use it:
# ##############

1) Note: Please use common courtesy...
get permission to use the image you will download and display.
It is also nice to give credit on your page as to the source of the image
and provide a link to the source if possible.

2) Set your settings in the section below

3) Upload the contents of this file as a .php file in the same directory
your image will display.
Example: you want a radar image ...  name it image-radar.php

4) Call the file in the html where you want the image displayed
<img src="image-radar.php" alt="Radar Image" width="200" height="200" />

5) If you use this script ... please let me know ..
http://www.642weather.com/weather/contact_us.php
I would also appreciate a link to my weather site on your links page ...

Tip: If you are loading more than one image with this script,
be sure to uniquely name this script for each image.
and be sure to uniquely name each image file name in the setting below

Tip: This script can also be manually run from the web browser
for diagnostic purposes. No parameters are required for the script.

Tip: If you change a setting like image size,
the change may not show up instantly because the image may be cached.
You can force a download reload of the image with ?reload=1
like this: http://www.yoursite.com/image-radar.php?reload=1

Tip: If you get a PHP error about file permissions,
try changing the folder permissions to 755, or on some servers 777

#####
# where is the image you are downloading?
#####
$ImageURL = 'http://www.642weather.com/weather/webcamimage.jpg';
# note: both samples are correct as long as they are actual image files
# $ImageURL = 'http://www.somesite.com/radar_latest.php?site=kdmx&prod=reflectivity1';
# $ImageURL = 'http://www.642weather.com/weather/webcamimage.jpg';
# Must start with http

# Note: This program will always save 2 image files to your web server
# $localimgName is a raw (temp image) file of the image downloaded
# $outputimgName is the (output image) for the web browser
# the following 2 settings will determine the file names.

#####
# The (temp image) - file name the image will be saved as on your server
#####
$localimgName = 'webcamimage-temp.jpg';
# note: use a unique name that is not a file on your server already
# or it will be OVERWRITTEN!
# note: only letters, numbers, dash, underscore, and dots allowed
# note: if the url being downloaded and the url of the file saved matches ..
# there will be an error so (use a different name for $localimgName)
# note: this script only supports .jpg .gif and .png
# note: this will convert png to jpg, png to gif, etc ..
# the extension you name it here is what it will be saved as
# note: If you are loading more than one image with this script,
# be sure to uniquely name this script for each image.
# Example: image-radar.php image-satellite.php
# ..and be sure to uniquely name each local image file
# Example:
# in image-radar.php,     name  $localimgName = 'image-radar-temp.jpg';
# in image-satellite.php, name  $localimgName = 'image-satellite-temp.jpg';

#####
# The (output image) - file name the image will be saved as on your server
#####
$outputimgName = 'webcamimage-cached.jpg';
# $localimgName and $outputimgName MUST HAVE SAME EXTENSION!
# note: use a unique name that is not a file on your server already
# or it will be OVERWRITTEN!
# note: If you are loading more than one image with this script,
# be sure to uniquely name this script for each image.
# Example: image-radar.php image-satellite.php
# ..and be sure to uniquely name each local image file
# Example:
# in image-radar.php,     name  $outputimgName = 'image-radar-cached.jpg';
# in image-satellite.php, name  $outputimgName = 'image-satellite-cached.jpg';

#####
# Local Directory - directory the images will be saved as on your server
#####
$localDirectory = './';
# use $localDirectory = './'; for same folder
# the folder must exist, you must make the folder yourself
# must end with a slash
# full path is recommended for cron scheduler use
# $localDirectory = '/var/www/html/weather/';

#####
# cache only option (to preserve animated GIFs when you do not need to resize, crop, or text overlay)
#####
$cache_only = 0; # just download and cache the file (ONLY!!), NO resize, NO crop, and NO text overlay
# Default set to 0 for no cache-only.
# note: setting this option $cache_only = 1;
# WILL BYPASS all other settings for resize, crop, and text overlay!!

#####
# resize options (uncomment only one of the settings below)
#####
// $resize_setting = 1; # use $new_width and $new_height
// $resize_setting = 2; # use $new_width
// $resize_setting = 3; # use $new_height
// $resize_setting = 4; # use $percent only to calculate $new_width $new_height
 $resize_setting = 5; # no resize
# 1) manual: use $new_width and $new_height settings below
# 2) use $new_width,  auto adjust height based on aspect ratio
# 3) use $new_height, auto adjust width  based on aspect ratio
# 4) use $percent only, image is resized by it's value in percent (i.e. 50 to downsize by 50 percent)
# 5) no resize

#####
# new image size for graphic display
#####
$new_width  = 400; # ignored with   $resize_setting 3 or 4
$new_height = 200; # ignored with   $resize_setting 2 or 4
$percent    =  50; # only used for  $resize_setting 4

#####
# jpeg compression percentage
#####
$jpegcompress = 95; # (range of 50 - 95 recommended)
# Example: 50 will make a smaller file but with less detail quality
#          95 will make a larger file but with very good detail quality
# used with $localimgName as a .jpg only, ignored for .gif or .png

#####
# Basic crop square from center - crops the image from calculated center in a square of $cropSize pixels
#####
$cropSize = 0;
# Default set to 0 for no basic crop.
# Example: $cropSize = 300; crops the image from calculated center to be a 300 pixel square.
# crop functions are performed on the original image BEFORE resize functions.
# resultant image can still be resized based on image resize options settings above.
# do not use basic and advance crop settings at the same time.

#####
# Advanced crop - crops an image using $cropStartX and $cropStartY as the upper-left hand corner.
#####
$cropStartX = 0; # crop from X pixels from upper-left hand corner.
$cropStartY = 0; # crop from Y pixels from upper-left hand corner.
$cropWidth  = 0; # crop area width  in pixels
$cropHeight = 0; # crop area height in pixels
# Default set to 0 for no advanced crop.
# crop functions are performed on the original image BEFORE resize functions.
# resultant image can still be resized based on image resize options settings above.
# do not use basic and advance crop settings at the same time.
# tip: a photo editor program will give you pixel X,Y locations to determine your crop settings

#####
# When to download a new image? (uncomment only one of the settings below)
#####
$download_setting = 1; # by last-modified
//$download_setting = 2; # by time interval
//$download_setting = 3; # always
# 1) only when the image last-modified timestamp changes at the source,
# 2) at a preset time interval like every 5 minutes,
# 3) always: (download and resize every hit)(less recommended, but good for testing)

#####
# Download new image every nnn seconds: like 600 for 5 minutes
#####
# note: only used with $download_setting = 2;
$refetchSeconds = 600;

#####
# Annotate text on image (optional, useful for text overlay on your image)
#####
$text1 = ''; # leave empty for no text1
$text2 = ''; # leave empty for no text2
$text3 = ''; # leave empty for no text3
# Note: $text1 = ''; no text will apear on the image
# See sample here: http://www.642weather.com/weather/image-webcam-thumb.php
# Example: $text1 = 'Live Cam';
# Multiline text also supported ...
# $text1 = 'Live
# Cam';
# See sample here: http://www.642weather.com/weather/scripts-image-handler.php#IHdemo

# Text alignment
$textalign1 = 'upperleft';
$textalign2 = 'lowerleft';
$textalign3 = 'centerbottom';
# your textalign options are ...
# upperright upperleft lowerleft lowerright center centertop centerbottom
$xmargin1 = 5; # side margin in pixels
$xmargin2 = 5; # side margin in pixels
$xmargin3 = 5; # side margin in pixels
$ymargin1 = 5; # top or bottom margin in pixels
$ymargin2 = 5; # top or bottom margin in pixels
$ymargin3 = 5; # top or bottom margin in pixels

# Font style
$fontstyle1 = 5; # There are 5 built in GD fonts: 1 2 3 4 5 ONLY!
$fontstyle2 = 5; # There are 5 built in GD fonts: 1 2 3 4 5 ONLY!

# Example: $ttfont1 = 'arial.ttf'
# Note: for $ttfont1 = ''; $fontstyle1 above is used
# DO NOT USE UNLESS YOU HAVE arial.ttf file in the same directory as this script!
# Any .ttf font files are supported,
# get free fonts: http://www.google.com/search?hl=en&q=free+ttf+fonts
# full path is recommended for cron scheduler use
# $ttfont1 = '/var/www/html/mosaic/htdocs/weather/arial.ttf';

#####
# Auto archive images feature (great for web cam images)
#####
$archive = 0;
# $archive = 0; # Disabled
# $archive = 1; # Enabled
# Live example: http://www.642weather.com/weather/cam-history.php
# Thanks Jim McMurry at http://www.jcweather.us/ for the archive feature code idea/suggestion

# How many archived images will be stored
$archivecount = 12;
# example setting: $archivecount = 12;
# only this many will be saved at a time, new ones are placed at webcamimage0.jpg
# newest image will be webcamimage0.jpg ... oldest image will be webcamimage12.jpg

# Where will the archived images be saved
$archivedir = './webcam/';
# use $archivedir = './'; for same folder, or something like this: $archivedir = './webcam/';
# best to put them in their own folder though
# the folder must exist, you must make the folder yourself
# must end with a slash
# full path is recommended for cron scheduler use
# $archivedir = '/var/www/html/mosaic/htdocs/weather/webcam/';

# prefix of the archived file name
$archivefilepre = 'webcamimage'; # no extension!! the 0.jpg part will be autogenerated
# example setting: $archivefilepre = 'webcamimage';
# newest image will be webcamimage0.jpg

# autogenerate thumb images of the archived?
$archivewiththumbs = 0;
# $archivewiththumbs = 0; # Disabled
# $archivewiththumbs = 1; # Enabled
# newest image will be webcamimage0.jpg and newest thumb will be webcamimage0-thm.jpg
$thumb_new_width  = 100; # thumb image width size (height will auto size)

#####
# memory_limit is a safety incase downloaded file is 1 gig or something
#####
# DO NOT CHANGE THIS unless you really know what you are doing
# if you get "out of memory error" on a normal size image,
# then you may want to increase the value slightly
# not all php installs have this setting enabled so it is commented out by default
# ini_set ("memory_limit", "10M");
