Title convert_syslinux_rev2.bat

REM updated 10.24.2014

REM Place this batch file anywhere and drag and drop the image files (bmp, 
REM jpg or png) to be converted on it (other image formats may not convert 
REM correctly). Converted files will be moved to the same directory as this file. 

REM Drag and drop single or multiple 640x480 (or with the same aspect ratio) 
REM .png or .bmp images into this batch file to convert them to Syslinux 
REM compatible splash images with ImageMagick. The converted file(s) will 
REM have "_splash" appended after the name and the extension(s) changed to png. 
REM This script works for files only (it will not work for folders). Tested on 
REM Vista and WinXP with ImageMagick portable installed to C:\Utilities folder.

REM CD "%~dp0" changes the working directory to the current directory 
REM (where this batch file is located)
REM "%~n1" is the filename minus the extension

CD "%~dp0"
set cdir=%~dp0%

echo.
echo Current directory is: "%~dp0"
