TIFF.PLT driver |
|
|
I have been reconfiguring a tiff driver for plotting Black and White
prints and medium resolution (150 DPI). The driver seems to work
great in TIFF mode but I noticed these lines in the driver:
; Format = 3 tells the lorip driver to generate a TIFF file.
; Quality identifies the type of compression
quality=1 ; Default compression
raster_compression/format=3/methods=(0)
I messed around with the "Format=" ranging from 1 to 7 and saw a
dramatic increase in file size in some cases, I am assuming that the
file being written is not a tiff and is infact and uncompressed format
such as BMP.
Ultimately I would like to control the method, format, and quality.
If one of the developers has a list of the numbers their corresponding
formats, methods, and quality settings it would be a great help.
Thank you,

This has been discussed a few times in the past. You need to look in a
header file in ..\mdl\include that does not install by default. I think it
is image.h, but can't remember for sure. deja.com is not working at the
moment. discussion.bentley.com should show this as well, but I can't find
it. You could try this post in one of Bentleys .plotting groups
(news.viecon.com).
