Taking BGRABitmap to the next level

(1/1)

PeteS:
The more I use it the more I find BGRABitmap to be a superb addition to Lazarus.  Well done again to all concerned, especially Circular.  :D

For myself, trying to write a photo editing tool, two things would really help:

1.  Much faster jpeg loading than using BM.LoadFromFile(fn).  Maybe there is already another way that I don't know about?

2.  Multi-threaded resampling, especially for downsizing.  Many screens are not much more than 1.3 MP, while many of the newer digicams are 18 and 24 MP.

I have no idea where to start with the first, but if someone can point me in the right direction I might have a bash at the second.

circular:
Thanks.

Well for jpeg, you may use another algorithm from another library.

For 2, I think that you would need clipped resample functions.
