I had asked this mailing list yesterday about HSV->RGB conversion. Many of
you gave me very good suggestions and programs to do this. But I am
thinking that since I've mapscript I could do this dynamically. Scenario:
I've a MS Word file from the client which has about 40-50 shapefiles and
info. on how to plot them e.g.:
Data Layer Legend Type Values-Field Value Label Symbol Color-Hue Saturation Value Outline
Fed_land.shp Unique Value Name Desoto Desoto 4 128 47 192 0.1
. . . . . .
So rather than converting all these HSV values to RGB and making a big
.map file in which each layer would have from 4-15 classes, would it be
more efficient to read the file (x'lated to a text fmt. etc.), read each
column, create a class obj., set it's color properties etc.
Would this be very slow compared to putting this info. in a map file?
Another idea is creating a database (MySQL) and putting this info. there,
but I think reading from database so much info. would make my script very
