Compatibility with older source code is not fully respected!!

If your actual code contain View3DOptions.ZoomText = true or false , in one pas source code there is no direct problem: the compiler will tell you that the property is not accepted. In the actual version this property have to be setted to ztno/ztyes.

But if View3DOptions.ZoomText = true or false is located in one dfm then the compiler ( at least Delphi 2010) kill the dfm writing things like
View3DOptions.ZoomText =
,!BEraseBackground





!B

Self
P,B
Rect


afterward, thelinker lead to an error such as

RLINK32: Unsupported 16bit resource in file ---.dfm

It took me a couple of days before I found why my previous source code wasn't useable.
I have had to remove the line View3DOptions.ZoomText = true or false from all the dfm backuped files outside of Delphi's SW with an editor supporting hexa format in order to avoid to modify the remaining part of the dfm file (opening dfm with notepad if most of the time impossible!).

Hi jpm,

As you probably know we always try to keep backwards compatibility. However, sometimes the implementation of a new feature forces us to break something or add some dirty code to ensure it. In this case, the giving more customization to the text zoom without changing the ZoomText property would imply adding a new property and several redundant conditions to the sources. We decided to change the ZoomText property from boolean to TCanvasZoomText (ztManual, ztNo, ztAuto).
Apologizes for the inconveniences. We'll try to document the future changes better.
