v201514_Error.png

1.
If building Tee9new.dpr in Delphi XE2 and later versions and running it, an error that says "invalid pointer operation" occurs.

To reproduce it, please follow the steps below:

(1)
Selects All features --> Chart styles --> Standard --> Line(Strip)
--> ImagePatterns and moves to another item, the error occurs.

(2)
Selects All features --> Chart styles --> Standard --> Bar
--> Brush Image and moves to another item, the error occurs. Please see the 
v201514_Error.png.

2.
Selects What's New ? --> Welcome!  --> New in Series --> Org Series with HTML Format.

With v2013.08, names used to be displayed under the faces, but not with v2015.14 (see v201308_Features_OrgHtmlFormat.png and 
v201514_Features_OrgHtmlFormat.png).

We uses the same Org_HtmlFormat.pas, so do you have any clues?

Thank you in advance for your help.

Kindest Regards,

1) and 2) resolved. 
From XE2 and up, the optional VCL TBrush.Bitmap should not be manually destroyed, as it was necessary in previous IDE versions.

3) One of the problems is the nodes are created with Transparency=100, and so the text is not visible. Investigating.

3) Fixed. The demo is setting Font.Color := clBtnFace, this is not allowed with TGDIPlusCanvas because in GDI+, "clBtnFace" is a full transparent color.

So, the demo must be changed to:

Font.Color := ColorToRGB(clBtnFace)

or, for example:

Font.Color := clWhite
