Problem with LoadMultiFromFile

[danthorpe]

Hi there !

I´m a programmer here in Brazil, and I´m using Vampyre under Linux, with Lazarus. And I´m having some problems with it, since I can´t load any images with the function :

var
  FImage : ImagingClasses.TMultiImage;

...

FImage := TMultiImage.Create;
FImage.LoadMultiFromFile('/root/Test/bank.png');

I always get an acess violation at this point, with the following output :

TApplication.HandleException Access violation
Stack trace:

Can anyone help me ? I´m in a big hurry with this project

One more thing, the call to the function works perfectly on WinXP. I´m using SuSe 10, and Lazarus 0.9.22

Thanks in advance

Could you please send me that image so I could test it?

Stack trace says it fails in TTextureFileFormat.TestFormat so you can disable
this file format and see if it helps. You can do it by commenting out
line with {$DEFINE LINK_ELDER}
in Imaging\Extras\Extensions\ImagingExtras.pas unit.

I could, by after some more tests, I noticed it happens to every image, and every image type (jpeg, gif, png ...). Also, I noticed that if I use

var
  ImgData: TImageData;

InitImage(ImgData);
LoadImageFromFile('C:\Documents and Settings\temp\Meus documentos\Delphi\Teste GIF\10.jpg', ImgData);

instead, it loads the image, but I don´t know how to display it.

So it is crashing only in Suse and Windows work ok?
I'll install Suse somewhere and try it. Works ok in Mandrake and Fedora though.

How do you want your image displayed? On VCL form or do you use OpenGL/DirectX/..?
If VCL is you case you can use DisplayImage or DisplayImageData functions or
TImagingGraphic class (Delphi's TBitmap descendant).
