Q:
|
||||
Hi,
|
||||
I am using the MultiGen API to read .flt files. Today I received a
|
||||
.flt file with Packed color for polygons. Going through the MGAPI
|
||||
documentation I didn't find anything about Packed colors in polygons
|
||||
except fltPolyFlagRgbMode, which is set to "1" in that file.
|
||||
Could you please answer the following questions:
|
||||
1) Name of the parameter used for Packed
|
||||
primary color in the fltPolygon structure;
|
||||
2) The function to read the values.
|
||||
Regards, Zoia.
|
||||
|
||||
|
||||
A:
|
||||
The short answer is:
|
||||
There is no fltPolygon attribute that defines the packed color.
|
||||
You need to use mgGetPolyColorRGB and mgGetPolyAltColorRGB to
|
||||
get the primary and alternate rgb values for a polygon.
|
||||
|
||||
The long answer, including a bit of explanation is:
|
||||
|
||||
OpenFlight databases can define color values in RGB space (packed
|
||||
color as you called it) or color index space. The fltHdrRgbMode
|
||||
field of the fltHeader record specifies which color space is used
|
||||
by the database.
|
||||
|
||||
If the database is in color index mode, you can get the RGB
|
||||
colors applied to a polygon by first getting the fltPolyPrimeColor
|
||||
and fltPolyPrimeIntensity attributes of the polygon and then
|
||||
converting those values to RGB by calling mgRGB2Index.
|
||||
|
||||
Note: The attributes fltPolyAltColor and fltPolyAltIntensity can
|
||||
be used to get the alternate color index and intensity.
|
||||
|
||||
If the database is in RGB mode, you can get the RGB colors applied
|
||||
to a polygon by calling the function mgGetPolyColorRGB. But if you
|
||||
take a closer look at this function you will discover that it
|
||||
returns the RGB colors for a polygon regardless of whether the
|
||||
database is in color index or RGB mode.
|
||||
If the database is in color index mode, mgGetPolyColorRGB acquires
|
||||
the color index applied to the polygon and looks up the
|
||||
corresponding RGB values for you.
|
||||
|
||||
So, if you are only after the RGB color values applied to a
|
||||
polygon, the function mgGetPolyColorRGB is always your best bet.
|
||||
Note: mgGetPolyAltColorRGB is the equivalent function to use to
|
||||
get the alternate RGB color values applied to a polygon.
|
||||
|
||||
Hope this helps.
