Release Date | Version | Details
--------------------------------------------------------------------------------
06/05/93 | 1.00 | Initial release
| |
26/05/93 | 1.01 | Bug fixes:
| |
| | * Crashed on 386+ machine if EMM386.EXE or
| | equivalent loaded with NOEMS option. No VCPI
| | detected unless EMMXXXX0 device driver available.
| |
10/08/93 | 1.02 | Bug fixes:
| |
Internal | | * PCX format output incorrectly duplicated the
Release | | last pixel in a scan line.
Only | | * Included missing 'Activation Timed Out' message
| | for Last Error (caused by DOS in permanently
| | busy state).
| | * Corrected error in horizontal pixel pan handler
| | for 256-colour modes.
| | * Changed method of calculating 64K video RAM
| | segment wrap versus paged memory access.
| | This was not a reported bug, as yet. With luck no
| | further bugs have been introduced by this.
| |
| | Enhancements:
| |
| | * Added /CLICKS switch at user request.
| | * Added extra interrupt 21h trap to avoid excessive
| | DOS busy timeout delays during intensive disk use.
| | * Implemented split screen and pixel pan handler for
| | the non-standard 256-colour mode using 4-plane
| | non-chained (interleaved) memory mapping.
| | * Base VGA detection (regardless of SuperVGA tests)
| | now overruled by the /V:VGA switch. This allows
| | the user to load SCREEN Thief regardless of video
| | card type and should be used with due caution.
| | * Added 24-bit support for PCX and BMP formats.
| | * Added RLE compression for 16 and 256 colour BMPs.
| | * Improved BMP creation method. Faster, less noisy.
| | * Added /RGB switch for quick x3 Max Width setting.
| | * Added /STREAMSIZE switch.
| |
20/08/93 | 1.10 | Bug fixes:
| |
Internal | | * Non-blinking pixels in 16-colour graphics mode are
Release | | now correctly interpreted with an intense attribute.
Only | |
| | Enhancements:
| |
| | * Added support for CIRRUS LOGIC CL-GD5422 chip.
| | Fully tested including HiColor and TrueColor modes.
| | * Added TXT, ASC and SCR Output Formats.
| | * Expanded TIFF support for 2, 4, 16 and 256 colours.
| | * Implemented more exact emulation of the VGA CRT
| | Controller. Now even ridiculous settings such as
| | a non-zero Preset Row Scan value (vertical panning)
| | under graphics modes are simulated.
| | * Added /BLINKATTR switch.
| | * Added support for OAK 037C/057/067/077 chip sets.
| | * Improved command line syntax error reporting.
| | * ST now only clears screen when run if already in
| | colour text mode. before it always reset the mode,
| | causing the display to flash on some adapters.
| | * Added PgUp, PgDn and first character jump for
| | scrolling help window list.
| | * Status screen updated to include most options.
| | * Added /FULLFRAME switch.
| |
26/09/93 | 1.50 | Enhancements:
| |
| | * Implemented LZW compression within TIFF format.
| |
07/12/93 | 1.55 | Bug fixes:
| |
Limited | | * GIF, TXT, ASC and SCR outputs now correctly
Release | | ignore the /RGB switch setting as these do
Only | | do not support 24-bit output and the surplus
| | allocation is simply a waste of memory.
| |
| | Enhancements:
| |
| | * Substantial changes made to the GIF encoding
| | algorithm. Linked list code searches rather than
| | table searches provide for a greatly improved
| | performance when capturing screens with many,
| | varied colours. Tests have shown improvements
| | of up to 1000% with 256-colour photo images
| | (e.g. 7 seconds not 70!). The down side is an
| | up to 100% increase in capture time for images
| | with few colours or colour changes (e.g. from 3
| | seconds up to 6 seconds) and a 33% increase in
| | memory usage (GIF encoding table entries are now
| | 4-byte, not 3-byte). The advantages out-weigh the
| | disadvantages.
| |
01/03/94 | 1.56 | Bug fixes:
| |
| | * Cured significant bug in the video buffer control
| | logic which caused occasional image corruptions
| | when capturing games using scrolling effects.
| | * Removed nasty bug introduced with v1.50 where
| | CGA 2 colour mode caused immediate hang.
| | * PCX format now correctly sets palette type as 1
| | for 24-bit images.
| | * Modified BMP output so that palette information
| | length matches biClrUsed field in all cases.
| |
| | Enhancements:
| |
| | * Added support for Tseng ET4000 chip set. Fully
| | tested other than 32K/64K colour modes.
| | * Added support for S3 86c911 chip set. Fully
| | tested including 640x480x32K mode.
| | * Cosmetic changes. Trailing backslash removed from
| | the directory entry on the status screen. Setting
| | directory back to current using single dot name
| | is recognised and redisplays <current>.
| | * Added CONFIG.ST file support.
| | * Documented hidden diag/dev/service switches.
