disp i have posted disp zip to alt binaries pictures utilities you may distribute this program freely for non commercial use if no fee is gained there is no warranty the author is not responsible for any damage caused by this program important changes since version fix bugs in file management system file displaying improve file management system more user friendly fix bug in xpm version reading fix bugs in targa reading writng fix bug in gem img reading add support for pcx and gem img writing auto skip macbinary header introduction this program can let you read write and display images with different formats it also let you do some special effects rotation dithering on image its main purpose is to let you convert image among different formts include simple file management system support slide show there is no limit on image size currently this program supports bits display if you want to use hicolor or truecolor you must have vesa driver if you want to modify video driver please read section hardware requirement pc or better msdos or higher min amount of ram is m bytes maybe less memory will also work i recommend min m bytes for better performance hard disk for swapping virtual memory the following description is borrowed from djgpp supported wares up to m of extended memory expanded under vcpi up to m of disk space used for swapping supervga color mode up to x xms vdisk memory allocation strategies vcpi programs such as qemm desqview and max unsupported dpmi microsoft windows features emulator bit unix ish environment flat memory model svga graphics installation video drivers emu and go exe are borrowed from djgpp if you use western digital vga chips read readme wd this go exe is a modified version for vesa and is completely compatible with original version but some people report that this go exe is not compatible with other djgpp programs in their system if you encounter this problem don t put go exe within search path please read runme bat for how to run this program if you choose xxxxx grn as video driver add nc to environment go for example go driver x xxxxx xxxxx grn nc if you don t have x add emu x xxxxx emu to environment go for example go driver x xxxxx xxxxx grd emu x xxxxx emu notes i only test tr grn et grn and vesa grn other drivers are not tested i have modified et grn to support bits display you don t need to use vesa driver if et grn doesn t work please try vesa grn for those who want to use hicolor or truecolor display please use vesa grn except et users you can find vesa bios driver from wuarchive wustl edu mirrors msdos

only when you run this program you will enter read menu whthin this menu you can press any function key except f if you move or copy files you will enter write menu the write menu is much like read menu but only allow you to change directory the header line in read menu includes d xx f xx t xx d display type f number of files t number of tagged files pressing space in read menu will let you select which format to use for reading current file pressing return in read menu will let you reading current file this program will automatically determine which format this file is the procedure is first check magic number if fail check standard extension still fail report error pressing s or s in read menu will do slide show if delay time is program will wait until you hit a key except escape if any error occurs program will make a beep escape to terminate pressing ins in read menu will change display type pressing alt x in read menu will quit program without prompting once image file is successfully read you will enter screen menu within this menu f is turn on you can do special effect on image pressing return show image in graphic mode press return space or escape to return to text mode pressing tab change processing target this program allows you to do special effects on bit or bit image pressing left right arrow change display type bits pressing space save current image to file b w dither save as black white image bit grey scale save as grey image bits full color save as color image bits true color save as bit image this program will ask you some questions if you want to write image to file some questions are format dependent finally this program will prompt you a filename if you want to save file under another directory other than current directory please press space after pressing space you will enter write menu you can change directory to what you want then pressing space this program will prompt you original filename pressing return this program will prompt you selected filename filename under bar this program supports bits display this program is memory greedy if you don t have enough memory the performance is poor if you want to save bits image try gif then tiff lzw then targa then sun raster then bmp then if you want to save bits image lossless try tiff lzw or targa or ilbm or sun raster no one is better for true bits image i recommend jpeg for storing bits images even bits images not all subroutines are fully tested this document is not well written if you have any problem suggestion comment about this program please send to u bicmos ee nctu edu tw i need your suggestion to improve this program there is no anonymous ftp on this site tech information program user interface and some subroutines written by jih shin ho some subroutines are borrowed from xv and pbmplus dec tiff v and jpeg v reading writing are through public domain libraries compiled with djgpp you can get whole djgpp package from simtel or mirror sites for example wuarchive wustl edu mirrors msdos djgpp for thoese who want to modify video driver get grx source code from simtel or mirror sites for hicolor and truecolor bits of colors is set to bits of colors is set to xc bits of colors is set to xc acknowledgment i would like to thank the authors of xv and pbmplus for their permission to let me use their subroutines also i will thank the authors who write tiff and jpeg libraries thank dj without djgpp i can t do any thing on pc jih shin ho u bicmos ee nctu edu tw
