PF_Pixel16

[_Ingchelio_Ingchelio_]

Hi,

Can anybody please tell me how I can obtain PF_Pixel16 data from PF_World (wP) ?

Thanks,
Ingchelio

PF_Pixel16 *p = NULL;
PF_GET_PIXEL_DATA16(&world, NULL, &p);

That's right, IF the world contains 16bpc pixels. Check for PF_WorldFlag_DEEP in the world, first.

Also, shouldn't we all be processing 32bpc pixels now? ;)

Alrite !!!
Thanks very much :)

I checked PF_WorldFlag_DEEP using the macro PF_WORLD_IS_DEEP
but everytime I checked, it always says that world is 8 bit,
even though I have set project settings to be 16 bit and
in the color pallete, it seems that the values of R, G, and B are already beyond 255.

Is there anything wrong ?

[Bruce Bullis]

How are you telling AE you want deep pixels? (i.e., are you setting appropriate outflags and outflags2 in the PiPL and during PF_Cmd_GLOBAL_SETUP?

[_Ingchelio_Ingchelio_]

I set the outflags only during PF_Cmd_GLOBAL_SETUP like this :

DllExport PF_Err main ( PF_Cmd cmd,
PF_InData *in_data,
PF_OutData *out_data,
PF_ParamDef *params[],
PF_LayerDef *output )
{
PF_Err err = PF_Err_NONE;

switch (cmd)
{
case PF_Cmd_GLOBAL_SETUP:
out_data->out_flags = out_data->out_flags | PF_OutFlag_DEEP_COLOR_AWARE; //supporting 16 bit color channel
break;

}
return err;
}

Is it not enough or is there anything wrong ?
Sorry about the tabbing but there is nothing I can do about it.

I have also added

/* [6] */
AE_Effect_Global_OutFlags {
33554432
},

to IO_PiPL.r but still the macro PF_WORLD_IS_DEEP returns 0.

> out_data->out_flags = out_data->out_flags | PF_OutFlag_DEEP_COLOR_AWARE;

The above is a logical statement, but doesn't set the flag. You need

|=

not

|

Thanks, Brooce.

But I have changed that to

out_data->out_flags |= PF_OutFlag_DEEP_COLOR_AWARE;

and still it does not work.
Wonder if something else cause it not to work.

[_Ingchelio_Ingchelio_]

Sorry, but I have made a mistake.
This plug-in is actually a AEIO plugin, not AEGP plugin.
So I cannot specify any AE_Effect_Global_OutFlags.

I have somehow managed to get AE to draw 16 bit by specifying
AEIO_MFlag_CAN_DRAW_DEEP to AEIO_ModuleInfo's flags.

Now the only problem is
when rendering, AE somehow claims that the world is 8 bit again,
even though the colors are actually 16 bit.

So I could import 16 bit contents and draw 16 bit contents,
but cannot export 16 bit contents.

Do I have to specify more flags to be able to render 16 bits ?
I have searched in the sample codes and headers but could not find any.

[_Ingchelio_Ingchelio_]

Finally able to render 16 bits.
Did not know I had to set AEIO_OptionsFlags in My_GetDepths
and set bit depth with AEGP_SetOutSpecDepth.

Anyway, thanks for all the help :D
