With this program you can converte almost all pictures which are in IFF-ILBM
form to Amiga. Because the converting almost all means transporting pictures
from another machine to Amiga I had to decide which format I use. IFF-ILBM was
natural choice because all other machines got programs to chance their weird
pictureformats to IFF. However I must tell you that there is new IFF-PBM
format what new PC-Dpaint2 supports so if you use it and want to move pics to
Amiga, remember save pictures to ILBM form.





                             HARDWARE REQUIRMENTS
                            ŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻŻ

                                   MINIMUM:

                                    Amiga
                                  512 KB Ram
                                 1 DiskDrive

Note: With this hardware the use is only bad joke!


                                   ENOUGH:

                                    Amiga
                                 1024 KB Ram
                                 1 DiskDrive

Note: This is enough in most of the cases.


                                    BEST:

                            Amiga (68030 or 68040)
                         1024 KB CHIP Ram & 1024 RAM
                               300 MB HardDisk

Note: $$$ ($$$$$$ in Finland)





                                     USE
                                    ŻŻŻŻŻ

The gadgets should be self-explanatory but some words about DreamHAM.

Use this mode when you want only see picture but don't want to edit it later.
Mode is fully automatical and will halve x-size when there is more than 320
pixels in row. Maximum display size is 313*624 and if size is greater only
part of the picture is showed. However all data is saved to file. You can't
save picture to IFF. So why to use this mode?
- Better quality: picture is sharper and cleaner than HAM.
! You can make tool icon for DHAM picture and show it from WorkBench !

                                  ŻŻŻŻŻŻŻŻŻ

WHY?
About 6 months or so I wanted to converte some pics from PC (SuperVGA) to
AmigaHAM. For that task I started to search converte programs and I found
two: VirtGIF and GIF2HAM. Both programs were designed to converte GIF-pics to
HAM but when I started to test them I soon founded that the programs could not
satisfy my needs because they were very slow and conversion was bad.
After that I started to code my own converte program which I thought to be
the best and the fastest in the world... Did I succeed? You can be the judge!

LONG RUN...
At first I of course started to think algorithm for picture conversion and it
was quite hard to invente. I can tell you that the algorithm is very simple
and reasonable fast. When the algorithm was ready I got great idea to improve
the HAM-mode. Then I simply coded the program and named that new mode as
DreamHAM. Of course I was too lazy to code normal HAM conversion routine at
the same time. But now (26.03.1991) I get enough strenght to do it. It is also
possible that in the 'near' future I'll make bitmap-routines..
