- Introduction to this Addendum
- -----------------------------------------------------------------
-
-
- Why an Addendum? This addendum covers changes in Image Alchemy
- that were made after the manual was printed.
- These changes consist of new file formats,
- changes to existing file formats, additions and
- changes in colouring options, and changes in the
- viewing options (for the MS-DOS version only).
-
- Where changes have been made, this manual covers
- the options in their entirety, saving you the
- trouble of having to look at both manuals for a
- single option.

- Image Alchemy for MS-DOS
- -----------------------------------------------------------------
-
-
- Use of extended If there is enough extended or expanded memory
- and expanded available, Alchemy will use it instead of the
- memory temporary file it would otherwise use during
- some conversions. To use extended memory you
- must have an XMS driver installed in the
- config.sys file (such as HIMEM.SYS or 386MAX).
- To use expanded memory you must have a LIM 3.2
- or LIM 4.0 expanded memory driver installed
- (such as EMM386, QEMM, or 386MAX).
-
- It is possible for there to be some
- incompatibility when using some older drivers
- and/or TSRs which also use extended memory.
- Therefore Alchemy's use of extended/expanded
- memory can be disabled. To disable use of
- extended and expanded memory, set an environment
- variable called 'alchemy' to 'x' (type "set
- alchemy=x" at the DOS prompt).
-
- Note that the availability of extended or
- expanded memory will not allow you to convert
- larger images, just speed up conversions. We
- also have a 386 version of Image Alchemy, which
- will allow 80386 and 80486 users to make use of
- the linear addressing space of those processors
- along with virtual memory to convert images of
- up to 32000 x 32000 (assuming you have enough
- disk space). Please contact us if you are
- running out of memory and are interested in
- upgrading to Alchemy/386.
-
- Checking for Alchemy will normally check to determine if
- 8514/A boards there is an 8514/A board installed in the
- computer when viewing images. However, this can
- cause problems with some network boards, as they
- use the same I/O addresses that 8514/A boards
- use. To disable 8514/A checking, set the
- environment variable called 'alchemy' to '8'
- (type "set alchemy=8" at the DOS prompt).
-
- Note that this can be combined with other
- options; for example, to disable both 8514/A
- checking and extended/expanded memory usage, use
- "set alchemy=8x".

-
- Limiting maximum Alchemy will automatically choose the lowest
- display resolution which will fit the entire image when
- resolution viewing images without specifying a display
- resolution with a VESA compatible VGA board.
- However, depending on the monitor and VGA board
- combination you have, this can be bad since the
- monitor may not support all t:Pçrÿ,j
