BRAW API Alpha Channel

Hi all,

I would need to know if the Blackmagic RAW API is setting the alpha channel at 100% in those pixel formats in the returned frame ? Is there any guarantee that it is ?

Code: Select all

    blackmagicRawResourceFormatRGBAU8                            = /* 'rgba' */ 0x72676261,
    blackmagicRawResourceFormatBGRAU8                            = /* 'bgra' */ 0x62677261,
    blackmagicRawResourceFormatRGBAU16                           = /* '16al' */ 0x3136616C,
    blackmagicRawResourceFormatBGRAU16                           = /* '16la' */ 0x31366C61,
    blackmagicRawResourceFormatBGRAF32                           = /* 'f32a' */ 0x66333261


Thanks

Hi, yes it should be. If not, please let us know as it would be a bug/regression.
Also bear in mind some packages invert the alpha channel - either way, we set it to 255 for 8 bit, 65535 for 16 bit and 1.0 for F32.
Thanks.

Thanks for your answer Mr. Hook. By "package" you mean other softwares ? Yes sometimes people talk about "transparency" so 0% transparency is 100% opacity (: , "alpha" is not descriptive enough

PS : we haven't seen any bug in that regard ! just confirming what's not written in docs

Yes, I mean other applications.
