Hi!

I am working with DM385 IPNC.

I want to make Date/Time stamp with transparent background.

By default transparency is disabled and background color is black.

I read other threads aobut SWOSD and transparency and found information about colorKey. So I made changes:

#define GLOBAL_ALPHA_VALUE (255)//(127)

createPrm.colorKey[0] = 0;//255; //Revisit
createPrm.colorKey[1] = 0;//255; //Revisit
createPrm.transparencyEnable = TRUE;//FALSE;

Now I have following result:

In place of completly black region I see grey block(It is transparent but it is grey, not original color). In place of symbols background only few pixels are "transparent", any way they are grey too..

IPNC RDK v3.5 includes swosd library in a binary format so I can't view source code.

What can I do with that?

Thank you.

Hi Dmitry,

For SWOSD reference please refer "SoftwareOSD_UserGuide.pdf" document, which can be found under "Collaterals/OSD" directory.

Thanks,
Prashant.

Thank you, Prashant.

After correct enabling, it works.

Hi Dmitry,
Can the Swosdlink connect with capturelink?

Hi Andani，
I'm working customized DM385 platform

My usecase is like that
