This is the announcement of the english version. So ... welcome to the LUG Library v1.0 !!!. What is LUG ? LUG is "Libreria de Utilidades Graficas" or, in english, "Graphic Utilities Library", and it's what is: a library of subroutines for image manipulation. What you get ? i . interfaces with file formats: - compuserve's gif - zsoft's pcx - truevision's targa - sgi's rgb - aldus' tiff - aldus' postscript - alias' pix - wavefront's rla - urt's rle - pbm/pgm/ppm - rgb - raw - rayshade's heightfield - jpeg ii . image editing functions: - resampling - blur - sharpening - cut - paste - median filter - masks - histogram equalization - ... and so on ... iii . image viewers: - for Silicon Graphics and IBM RISC 6000 ( GL Library ) - for HP9000 series ( Starbase Library ) - for any kind of X11 plattforms ( Xlib Library ) - for PC386/486 with DJGPP compiler ( GRX Library ) - for Linux ( VGA and VGAGL libraries, text mode ) ... and it's a LIBRARY!!!, not a program. YOU! will be the person who write the programs, not others. Excitant, isn't it?. And example?. You have a wonderful 735 (hp9000) which calculates the fast fourier transform in nano-seconds, but what if you have to display all these images on a PC ?: #include #include main( int argc, char **argv ) { bitmap_hdr in; read_8bitmap_file( argv[1], &in, 512, 512 ); write_gif_file( argv[2], &in ); } Too easy, isn't it ?. A more complex example ?. We wanna add a signature to a lot of images, display it in our SGI and write it in 256 colors TIFF format: #include #include #define SIGNATURE "/usr/people/rivero/.signature.tga" main( int argc, char **argv ) { bitmap_hdr in, super, out; bitmap_hdr aux; /* Read the input file ( any format ) */ read_lug_file( argv[1], &in ); /* We'll need a true color image */ if ( in.depth < 24 ) { copy_bitmap( &in, &aux ); freebitmap( &in ); to24( &aux, &in ); freebitmap( &aux ); } /* Read the super image */ read_tga_file( SIGNATURE, &super ); /* Fade them */ chroma_bitmaps( &in, &super, &aux ); /* But we wanna a 256 colors image */ quantize( &aux, &out, 256 ); /* Show it (the true color image) */ show_bitmap( argv[2], &aux, 0 ); /* And write it */ write_tiff_file( argv[2], &out ); } I hope you get it :-). LUG have been tested on SGI, HP9000 (s300/400/800), INTERGRAPH, DEC, IBM R6000 and PC (Linux/MSDOS) machines, and it appears work fine. If your machine is a PC with MSDOS, you'll need the DJGPP compiler ( or an equivalent ). The original site distributor of this package is telva.ccu.uniovi.es (156.35.31.31): /uniovi/mathdept/src/liblug-1.0.1.tar.gz.
