NAME

       matroxset - switch the output mode of Matrox video cards

SYNOPSIS

	  matroxset [OPTIONS] [VALUE]

OPTIONS

       -c  Get/set control value.

       -e  Edit controls interactively.

       -f DEVICE
	   Manipulate the frame buffer DEVICE (default is /dev/fb1).

       -l  List controls

       -m  Connect this frame buffer to the outputs specified in VALUE (0 is none, 1 is primary, 2 is secondary, 4 is digital flat panel; these
	   values may be summed for multiple outputs).

       -o OUTPUT
	   Set OUTPUT (0 is primary, 1 is secondary, default is 1) to the output mode VALUE (128 is monitor, 1 is PAL TV, 2 is NTSC TV).

       -p  Display information about blanking.

DESCRIPTION

       Output Matrox card video to television. PAL 50Hz and NTSC 59.94Hz are supported, Composite and S-Video output.

       Contains two demo programs, normal and swapped. First selects CRTC1 on first output and CRTC2 on second one. Swapped connects CRTC1 to
       secondary head and CRTC2 to primary head. You can use these programs if you need text mode or 8bpp mode on TV, as CRTC2 is incapable of
       these modes.

       In program call, If VALUE is specified, set the specified option to VALUE. If VALUE is not specified, retrieve the value of the specified
       option.

NAME

       pngcheck - Test PNG image files for corruption, display size, type, compression info

SYNOPSIS

	 pngcheck [-vqt7f] file.png [file.png [...]]
	 pngcheck [-vqt7f] file.mng [file.mng [...]]
	 pngcheck -{sx}[vqt7f] file-containing-PNGs...

	 ... | pngcheck [-sx][vqt7f]

OPTIONS

       -v  test verbosely (print most chunk data).

       -q  test quietly (only output errors).

       -t  print contents of tEXt chunks (can be used with -q).

       -7  print contents of tEXt chunks, escape chars >=128 (for 7-bit terminals).

       -p  Print contents of PLTE, tRNS, hIST, sPLT and PPLT (can be used with -q).

       -f  Force continuation even after major errors.

       -s  Search for PNGs within another file.

       -x  Search for PNGs and extract them when found.

DESCRIPTION

       pngcheck is the official PNG tester and debugger. Originally designed simply to test the CRCs within a PNG image file (e.g., to check for
       ASCII rather than binary transfer), it has been extended to check and optionally print almost all the information about a PNG image and to
       verify that it conforms to the PNG specification. It also includes partial support for MNG animations.

       It can dump the chunk-level information in the image in human-readable form. For example, it can be used to print the basic stats about an
       image (dimen sions, bit depth, etc.); to list the color and transparency info in its palette; or to extract the embedded text annotations.
       All PNG and JNG chunks are supported, plus almost all MNG chunks (everything but PAST, DISC, tERm, DROP, DBYK, and ORDR). This is a
       command-line program with batch capabilities (e.g., pngcheck *.png).

ENVIRONMENT

       None.

FILES

       None.
