Download images when Download=1 won't work for you...

This is a little helper app you can put in your skin folder (or anywhere really) which allows you do download images retrieved by WebParser.dll without some of the limitations of "Download=1". I have included a sample skin .ini file to demonstrate its use.

Here is the Image.ini file so you can check the documentation and use before you download it and give it a try:

Code: Select all

;===========================================================================
; Rainmeter configuration file
; Updated June 26, 2009
;
; This sample skin demonstrates the use of 
; GetWebImage.exe by Jeffrey Morley
;
; The format for GetWebImage.exe is:
; "FullPath\GetWebImage.exe" "http://URL/ImageToGet" "NameToSaveAs.ext"
;
; "URL" is the full URL and path to the image: "http://pics.com/images/"
;
; Using this program has the following advantages over "Download=1" on
; a WebParser "Measure"
; 
; 1) The image is stored wherever you specify, not as a "temporary"
;    file, so it can be used repeatedly in a skin on multiple meters.
; 2) If you have a website or RSS feed (like News.Google) which
;    displays different images, with a different location but the same
;    image name, this will allow you to download those multiple images
;    without the same name causing the second image to overwrite the first.
; 3) The image you download is stored where you specify, and can be
;    used for other purposes, rather than being deleted as is the 
;    case with WebParser's "Download=1".
; 
; Using this program has ONE disadvantage however, and this should
; be considered when deciding to use this or just "Download=1".
; 
; 1) The "FinishAction" command in Rainmeter ONLY fires on a WebParser
;    measure which has a "RegExp=" statement.  So if you need to 
;    download multiple images in one skin, you will have to "go back"
;    to the website to retrieve each image. You cannot use this 
;    program with a WebParser measure which "references" another
;    WebParser measure and just uses "StringIndex=x" to get the result.
;    I have an example of what WON'T work at the bottom of this skin.
;===========================================================================

;[BEGIN CONFIG FILE]========================================================

[Variables]
RootURL="http://www.rainmeter.net/forum/"
GetWebImageExe="C:\Program Files\Rainmeter\Skins\GetImage\GetWebImage.exe"

[MeasureDL]
Measure=Plugin
Plugin=Plugins\WebParser.dll
UpdateRate=1800
Url=#RootURL#
RegExp="(?siU)id="logo"><img src="(.*)"/>.*"
StringIndex=1
FinishAction=!execute ["#GetWebImage#" "#RootURL#[MeasureDL]" "DownloadedImage.png"]

;
; NOTE - If the HTML dispays the image with the full URL/image.png instead of 
; a "relative" path like this example, you can return the whole thing in 
; StringIndex 1, and just leave off the #RootURL# in the command as it will 
; already be in the result returned in StringIndex 1.
;

[MeterImage]
Meter=IMAGE
ImageName="DownloadedImage.png"
X=0
Y=0

;[END CONFIG FILE]===================================================================


;[WHAT WE JUST DID]==================================================================
;
; The full URL, path and name of the image we wanted to retrieve is:
;
; http://www.rainmeter.net/forum/styles/saphic/imageset/site_logo.png
;
; So the #RootUrL" is "http://www.rainmeter.net/forum/"
;
; And it is found in the source HTML as:
;
; <a href="./index.php" title="Board index" id="logo"><img src="./styles/saphic/imageset/site_logo.png"/></a>
; 
; So we used our RegExp to retrieve ./styles/saphic/imageset/site_logo.png
;
; If you put the #RootURL# together with the information retrieved into StringIndex 1, you have:
; 
; http://www.rainmeter.net/forum/./styles/saphic/imageset/site_logo.png
; 
; This is passed to GetWebImage.exe with "#RootURL#[MeasureDL]" in the "FinishAction" statement
; 
; GetWebImage.exe downloads the image, and stores it as "DownloadedImage.png".  It will be 
; stored in the current directory in this example, but you can specify a full path if desired.


;[WHAT WON'T WORK]==============================================================================
;
; [MeasureDL]
; Measure=Plugin
; Plugin=Plugins\WebParser.dll
; UpdateRate=1800
; Url=#RootURL#
; RegExp="(?siU)id="Image1"><img src="(.*)"/>.*id="Image2"><img src="(.*)"/>"
;
; [MeasureImage1]
; Measure=Plugin
; Plugin=Plugins\WebParser.dll
; UpdateRate=1800
; Url=[MeasureDL]
; StringIndex=1
; FinishAction=!execute ["#GetWebImage#" "#RootURL#[MeasureImage1]" "DownloadedImage1.png"]
;
; [MeasureImage2]
; Measure=Plugin
; Plugin=Plugins\WebParser.dll
; UpdateRate=1800
; Url=[MeasureDL]
; StringIndex=2
; FinishAction=!execute ["#GetWebImage#" "#RootURL#[MeasureImage2]" "DownloadedImage2.png"]
;
; Unfortunately Rainmeteter will NOT fire the "FinishAction" commands on a measure without
; a "RegExp=" statement so you would need two separate measures which go to the web site
; and get one image each in StringIndex=1. There may be a way around this with having
; the measures "MeasureImage1" and "MeasureImage2" use a RegExp= statement to "search"
; the results of StringIndex "0" of "MeasureDL" instead of using StringIndex=1, StringIndex=2.
; Feel free to give that a try and let me know if it works!
;
GetWebImage.exe was written by me in AutoIt3, and will work on XP/Vista/Seven. You will need to set it to run as "Administrator" on Vista/Seven if you have UAC turned on and are saving the image anywhere in "C:\Program Files".

Here is the full AutoIt3 source code for GetWebImage.exe

Code: Select all

#include <array.au3>

If $CmdLine[0] = 0 Then
	Exit
EndIf

InetGet($CmdLine[1],$CmdLIne[2],1)

Exit
Not a lot of code for a lot of functionality! ;-)
