GIFCON version 2 SIOU This program allows to view GIF files on your favorite CPC computer. You can also save the screen in .scr format compatible with CPC memory and modes once the GIF file has been viewed. The program needs the CPC full memory capacity and runs only on CPC 6128, as it requires 128 Ko. Loading and running the program will erase any data up to &A000 in central memory and all the 2nd bank. ________________________________ This program is SHAREWARE ! It has been given kindly by me or a friend, but remember I spent time to implement GIF decoding. It is not as easy as you could believe ! If you use this software, send me something to encourage my work ! I will be happy with 15 FF. It should pay the mail, disks... ________________________________ - Here follows the main features of the version 2: * Illimited GIF source file size. The only limitation is your disk capacity and the associated driver. Typically 187 Ko for a 3' drive and 253 Ko for a 3'1/2 drive (AMSDOS). * 80 Ko free memory for the conversion process * 2 color conversion processes available ________________________________ You can access any time to the main menu by pressing <space>. If a file was in process, the program will automatically stop it. - Menu option description: A: Select drive A for operation (load or save) B: Select drive B for operation. Caution may be observed using this option. This option assumes you have a 'modern' 3'1/2 or 5'1/4 PC drive connected. Therefore selecting B: will change disk parameters to allow fast disk operations. Test if your drive does meet the B: conditions. If not, there will be a read fail. If you are in this case (unlucky guy !), ask me. You can anyway use the program but: - You do not use drive b: - or you must switch your drive selector to A: (If you don't have it, it is time for you to upgrade your CPC configuration...) C: Catalogue. Is it necessary to describ this option ? S: Save the displayed image in .SCR and .PAL format (conpatible with IFFCON and HIPER). The name will be the same as the original GIF file. Once the image is displayed completely, just press 'S'. Do not press any other key: a message could be displayed OVER the image. V: Load, decod and view a GIF file on selected disk. Input the file name WITHOUT the .GIF extension. The color conversion uses the 1st method converting the maximum of the GIF original colors into the palette. The border becomes blue when the conversion is over. If you get another color, a problem occured and the conversion is aborted. W: As V but uses the 2nd method for color conversion. Some colors are always put into the palette before filling it with the GIF converted colors. ?: Help. This option is not active. It will clear the screen and display the main menu. Q: Quit... You may resume by typing 'call &2000' but you MUST put the original disk in the current drive. _________________________ - What is not implemented yet: * Interlaced line decoding * 2 colors GIF conversion * Other useful functions coming with next versions. _________________________ ................................... . . . - GIFCON version 3 will feature:. . . . * Choice of displayed format . . * Interlaced line decoding . . * Information on GIF format . . * Special display mode . . using more than 27 colors... . . * Surprises... . . . ................................... _________________________ Note: - During loading or after a call &2000 from BASIC you may hear a strange noise from your disc drive. This noise is NORMAL. - Please report any bug to SIOU: CNX SIOU MASSICOT LAURENT 23 RUE BOUQUIERES 31000 TOULOUSE (FRANCE)
