Re: Graphics Conversion (was Re: NetScape 5)



Hello - Happy New Year - Best Wishes for '99 - EURO is here

How Convert 3200 could be faster and better than before?

1/ MEMORY
-> Changing our internal memory management for uncompressing pictures
   -> Load picture as is :
      - A 4 color file would become a 4 color handle in memory instead
        of becoming a 8 bit color picture. Twice the size in memory!

2/ I/O
-> Removing our 64kb buffer for loading
   -> Working on file in memory instead of loading chunk per chunk
-> Removing our 64kb buffer for writing
   -> Directly saving data from uncompressed picture instead of buffer

3/ PICTURE UNCOMPRESSION
-> Removing our 1-7 bit to 8-bit automatic pixel unpacking routine.
   -> Less job on pixel means faster handling

4/ PICTURE SIZE
-> Removing the 1280*800 size limitation of the pictures
-> Removing the 256 color limitation. Happy TrueColor

5/ GIF
-> Removing data checking. Please have fun with Prism, try to load a
buggy picture! SuperConvert & Convert 3200 both check for buggy pictures.
This means a loss of time in uncompressing the picture and prevents the
computer from crashing ! Happy stack coding
-> So slow for 4 bit color pictures is weird. Please send some pictures!

The tool is not perfect, I agree. We just do the best we can, maybe an
update...
...when time will be with us!
