Wallpaper Cycle

Recommended Posts

mexykanu

Hi,

This is my first published script so here goes.

WallpaperCycle - changes your wallpaper once every X minutes with pictures in a specific folder.

It is controllable only by the Tray icon (click or right-click) and reads its startup settings from a .ini file.

Credits (some includes were found on this forum) :

1. _ReduceMemory by wOuter

2. _ChangeDestopWallpaper by FlyingBoz

Current features:

- You can choose any folder which contains at least one .JPG / .BMP / .PNG file.

- You can set the time each wallpaper is displayed (a maximum of 99 minutes)

- You can set how the wallpaper are displayed (centered, stretched or tiled)

- The program has a "autostart" feature - it can start every time Windows starts.

- Memory usage optimization

Total time spent: about 20-24 hours.

Compiled size: 401 KB (including .ini file)

RAM used at startup: 900 KB

Maximum used RAM: 2000 KB

I'm open for suggestions/improvements/bugs so please don't hesitate to post.

Thanks,

mexykanu.

edit: Removed source since it's not mandatory

Works fine on Vista x32!

One suggestion: wallpaper change duration in seconds instead of minutes.

Good job! :)

Thanks,

I don't really understand what you mean :) Could you provide a video or something like a sample ?

How do you do to refresh the desktop ?

I think you call a dll... But why ?

The program doesn't refresh the Desktop. The flickering icons are somewhat of a bug which resulted from changing the wallpaper. If it helps i can give you the respective code.

Cheers

mexykanu,

I have been using your script recently and have a few comments:

- when the computer starts I get a dialog box requesting me to choose the init.ini file. Am I doing something wrong? It would be good if it would automatically choose the init.ini file.

- the windows xp options are limited for sizing the pictures i.e. tile, centered, stretched. However, none of those is real useful when the pictures are bigger than your desktop ... stretched distorts the picture, centered doesn't help and neither does tiled. It would be good to have the option to have the program resize the image before setting it as the desktop.

Below is an edit of a script originally written by n3nE that I edited for my digital photo frame. You would need to find out the resolution of screen first then pass that as the width and height.

The centered / tiled / stretched is probably the biggest killer for me since all my photos are high res and my laptop screens are not.

Other than that the script runs well, uses minimal resources and looks good in the taskbar...good work.

; #FUNCTION# ====================================================================================================================
; Name...........: _ImageResize
; Description ...: Resizes image to values as given and saves to $sOutImage
; Syntax.........: _ImageResize($sInImage, $sOutImage, $iW = -1, $iH = -1, $bPreserveAR = True, $bStretch = False, $bUseExtensions = False)
; Parameters ....: $sInImage - Full path and filename of the image to be resized
;                  $sOutImage - Full path and filename of the file to save to
;                  $iW - Width in pixels (optional - Will default to $sInImage width)
;                  $iH - Height in pixels (optional - Will default to $sInImage height)
;                  $bPreserveAR - Boolean, True to preserve aspect ratio, False to not (optional - Default True)
;                  $bStretch - Boolean, True increases small images to fit, False does not (optional - Default False)
;                  $bUseExtensions - Boolean, Indicates whether to use the extensions list or not (optional - Default False)
; Return values .: Success - Returns a 1
;                  Failure - Returns a 0
;                  @Error  - 0 = No error.
;                  |1 = Input file does not exist
;                  |2 = Not a recognized image format
;                  |3 = No resize performed
; Author ........: Original from n3nE
;                  Edited by JasonLA
; Modified.......: 04/06/2009
; Remarks .......: This function assumes that if a H and W are inputted then the user does not want an image bigger than either of
;                   those numbers. Aspect Ratio and Stretch are taken into account if required however the image will never be bigger
;                   in either dimension than what was requested.
; Related .......:
; Link ..........;
; Enhancements ..; add option to use a specify a ratio based resize eg. 0.5 would be half original size, 2.0 would be twice original etc.
;                  add more file extensions
;                  add ability to pass file extension array to function
;                  add check that $sOutImage can be written to
