Scale a .P...ale effects(1)  General Commands Manual Scale a .P...ale effects(1)

NAME
     scalex  - Scale a .PNG image using the fast implementation of the Scale ef-
     fects

SYNOPSIS
     scalex [-k N] input.png output.png

DESCRIPTION
     Scale2x, Scale3x and Scale4x are real-time graphics  effects  able  to  in-
     crease  the size of small bitmaps guessing the missing pixels without blur-
     ring the images.

     They were originally developed for the AdvanceMAME project in the year 2001
     to improve the quality of old games running at low video resolutions.

     The specification of the algorithm and more details are at:

	 http://scale2x.sourceforge.net

     These command line tools read a .PNG file and write another image with  the
     effects applied.

     The fast implementation of the Scale effects is used. It imposes some limi-
     tations of the type of the image usable. Specifically :
     *	    Only the pixel sizes of 1, 2 and 4 bytes are supported. If the image
	    has another pixel size it's automatically converted.

OPTIONS
     -k N, --scale N
	    Select the scale factor. Available values are 2, 2x3, 2x4, 3, and 4.
