I'm dealing with DIBs.

I'm using 'SetDIBitsToDevice' API to display DIBs.

But It doesn't handle with transparent color...

Do I have to convert it to DDB before display?
I used to use that way to skip transparent color.
But, I think... Converting DDB looks not efficient. :(

How can I display DIBs with skipping transparent color (without converting DDB)? :(

Thank you for reading!
Have a nice day! :)

Use masks and BitBlt.

Thank you for your replying...

But, Can you display DIBs with 'BitBlt'?

As I mentioned, You should not convert DIB to DDB.

Select the DIB into a Dc, Blt the Dc. Do the selection once and resuse the Dc when needed.

Also take a look at MaskBlt.
