	PLACER - vector/bitmap converter and composer
	2003, Barkhatov Andrej Eduardovich, abarkhatov@yahoo.com

Fast, small program to convert and compose vector/bitmap graphic files in
the following formats:
	Bitmaps
	* GIF
	* BMP
	* JPEG
	* TIFF
	* G3-Fax

	Vector(or mixed)
	* AutoCAD DXF
	* Windows Enhanced EMF/WMF
	* ArcView SHP 
	* Gerber
	* HTML (output only)
	* Adobe PDF (output only) 

	The program can be used for
	* viewing common graphic formats 
	* mixed graphic composition 
	* image processing/vectorization

	File formats supported
	* Input DXF is ASCII mode 2D, used for vector data exchange
	(layers, True Type fonts, LW poly-lines are processed)
	* Input BMP is uncompressed, palette and rgb
	* Input TIFF is uncompressed, multi-page, palette and rgb
	* Input G3-Fax is CCITT - 1D compressed, black/white
	* Input GIF is standard, Output - is RLE compressed, interlaced
	* Input JPEG is standard, progressive 
	* Input EMF/WMF can contain bitmaps, Output - is the system standard
	* Input SHP is ESRI shape file associated with DBF attributes
	* Input GBR Gerber PCB is a subset of RS274X standart
	* Output HTML is Microsoft VML Web standard
	* Output PDF is ZLib compressed, version 1.2

	To make overlaid composition several bitmaps and vector files can be
	opened onto a page with optional position/scale parameters. 

	Position and scale factors can be adjusted using the keyboard or through
	point and pull of a border. 

	With ten buttons on the right side some image processing could be done.
	The functions are:
		* "Histogram" - 2d/1d image histogram 
		* "Pyramid" - Pyramid filtering
		* "FloodFill" - Flood filling (from image center)
		* "3->1" - 3 to 1 channel convertion
		* "CannyEdge" - Canny edge detection, vectorization
		* "Approximate" - Curve approximation, simplification
		* "Snake" - Active contours energy-minimization
		* "ErodeDilate" - Erode or Dilate
		* "Smooth" - Gaussian blur
		* "Threshold" - Fixed-level thresholding
	Each button has the parameter field for processing strength choosing.

	The program contains:
	* Ed Casas EFax 
	* Eddie Kohler GifSicle
	* FastIO System ClibPDF
	* Frank Warmerdam ShapeFile
	* Intel IJL
	* Intel OpenCV
