TTree is slow in design with Teechart2013

Post by mivtee » Thu Jan 23, 2014 5:19 pm

Hi,
I have Delphi 2007 on windows 7, when I put some pictures in design in TTree it's very slow.
I tried this:

Code: Select all

(Tree2.Canvas as TGDIPlusCanvas).AntiAlias:=False;
: it doesn't change any thing.
I tried with

Code: Select all

 Tree.Canvas:=TTeeCanvas3D.Create;
: it's very better but the transparency doesn't work.

Why it's so slow with TGDIPlusCanvas?
Why I don't have transparency with TTeeCanvas3D?

The source and binary of a sample project is joined.

Hello,

I'm not sure about what exact TeeChart version are you using but I see the transparencies with GDI (TTeeCanvas3D) here with TeeChart v2013.09:

If I clic on the button, it switch in GDI,after this, the picture has not a background transparent

Is there a solution to have image(png) with transparent background with GDI?

Hi,

In GDI+, TeeTree is very slow only when I active the tranparency of the picture.
TeeChart is very slow too if I put a picture and active BackImageTransp.

Actualy I use Delphi 2007, do you have the same problem with other versions of Delphi?

It seems to depend on the image format too. Take a look at the project attached

I reproduce this with Delphi 7. I don't think it's IDE dependant.
