Hello,

While developing a software, it came to my notice that files saved from ImageEn's routine: LayersSaveToFile gives data error while opening such files.

Let me try and explain.

I have developed the main software in XE6 and it is working fine. I am able to save files using LayersSaveToFile function and also load them using LayersLoadFromFile function.

I am maintaining the source of my software in two different version of Delphi.
1. D2007 and 2. XE6.

If I try to open files saved by the executable generated by XE6 in the executable generated by D2007. I get the Data Error message and the file in question that Delphi IDE shows is iezlib at line # 386 (raise EZDecompressionError.Create(z_errmsg[2 - code]);)

Here is the screen shot of the error message that I receive.




TIA

Hi Yogi

What is the version of ImageEn on both delphi versions? Can you please attach an example of the file saved by your XE6 executable.

ImageEn version is 6.2.1 on both Delphi.

The code fragment that I am using is in XE6 to save the file:
MainForm.ImageEnViewMain.LayersSaveToFile('c:\tmp\YogiTest001\0002.ams');

Here file extension is .ams

The code in Delphi 2007 for loading the file is:
ImageEnViewMain.LayersLoadFromFile('c:\tmp\YogiTest001\0002.ams');



TIA

Hi Yogi

Your file loads as corrupted in both D2007 and XE6, but I can't reproduce when I try to do the same.

So I suspect that is something odd is happening with your XE6 installation. Presumably you have an older version of iezlib.pas on your path.
