IJL vs. IPP

[macom2005]

Hi,

i am using IJL 2.0 from IPP 4.1 and have good results. The speed of jpeg encode / decode increase about 140% compared to delphi standard. I am thinking about using the IPP Jpeg functions instead of IJL. My questions :

- Is it worth to do the work. Can this speed up my program again ?

- Are there delphi headers available to use this ippi functions ?

Thx!

Hi,

I'm sorry for delay with answering, just was very busy last days. Of course, we have answer. In general, so-called IPP JPEG codec will be faster than IJL (even based on IPP), because of more efficient implementation. But regarding Delphi support - we do not have plan to provide such support in the nearest release, so if you are interested in it you can:

a) submit this feature request through premier.intel.com and we will consider if it fits our resources and plans

b) to implement Delphi interface by yourself

In any case, I recommend you to take a look on JPEGView sample, which contains new IPP JPEG codec implementation to estimate its performance and functionality. You can download JPEG samples through this link
