Hello,

When should we use IEGlobalSettings().UseGDIPlus and when not to use it?

What advantages do we get by using GDIPlus?

TIA

UseGDIPlus is used to use GDIPlus canvas drawing. The GDIPlus canvas supports transparency along with antialiasing that GDI does not. So for the highest quality canvas drawing use GDIPlus. One disadvantage of GDIPlus is that the drawing methods are slower than GDI.

Bill,
Thanks for the feedback.

I thought using GDI+ would increase performance of ImageEn in handling large images.

Finally I know that it is not useful for me at this point of time.

As far as I know, the only thing that increases the ability to quickly handle large images is by using the IELib dll's. The dll's increase loading speed by about 25%. Generally when speed and increased memory is needed by my projects, I use the dll's and compile as Win64.
