NAME

       gmerlin_imgconvert - Image converter

SYNOPSIS

       gmerlin_imgconvert [-co options] input_image output_image

DESCRIPTION

       Image converter

OPTIONS

       -co <options>

	 Conversion options
	 q=<number> (1..5, default: 2)

	 Conversion Quality

	 Set the conversion quality for format conversions. Lower quality means more speed. Values above 3 enable slow high quality calculations.

	 sm=<string>

	 Supported strings: auto nearest bilinear quadratic cubic_bspline cubic_mitchell cubic_catmull sinc_lanczos

	 Default: auto

	 Scale mode

	 Choose scaling method. Auto means to choose based on the conversion quality.  Nearest is fastest, Sinc with Lanczos window is slowest.

	 so=<number> (4..1000, default: 4)

	 Scale order

	 Order for sinc scaling

	 dm=<string>

	 Supported strings: none copy scale

	 Default: none

	 Deinterlace mode

	 Specify interlace mode. Higher modes are better but slower.

	 ddm=<string>

	 Supported strings: top bottom

	 Default: top

	 Drop mode

	 Specifies which field the deinterlacer should drop.

	 fd=[1|0] (default: 0)

	 Force deinterlacing

	 Force deinterlacing if you want progressive output and the input format pretends to be progressive also.

GENERIC OPTIONS

       The following generic options are available for all gmerlin applications

       -help

NAME

       gifrsize - A program to resize image size by an integer factor, deleting bits when scaling down and duplicating bits when scaling up.

USAGE

       gifrsize [-q] [-S X Y] [-s Scale] [-x XScale] [-y YScale] [-h] gif-file

       If no gif-file is given, GifRSize will try to read a GIF file from stdin.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

	       Quiet mode.  Defaults off on MSDOS, on under UNIX.  Controls printout of running scan lines.  Use -q- to invert.

       [-S X Y]

	       specifies the exact screen dimension of the output GIF.

       [-s Scale]

	       Set scaling factor for both x & y direction to Scale.  Default is 0.5. Note this is a floating point number.

       [-x XScale]

	       Set scaling factor for x direction to Scale.  Default is 0.5.  Note: this is a floating point number.

       [-y YScale]

	       Set scaling factor for y direction to Scale. Default is 0.5.  Note: this is a floating point number.

       [-h]

	       Print one line of command line help, similar to Usage above.
