PeterPanino	Posted - Jul 02 2021 : 05:01:37 Does TImageEnView.IO have a built-in function CanLoadFile(AFile) or similar that returns True if the file can be loaded in ImageEnView?

xequte	Posted - Jul 06 2021 : 03:32:05 Hi Peter These should all return ioUnknown. attach/xequte/20217633114_UnknownImg.zip 239.89 KB Nigel Xequte Software www.imageen.com
PeterPanino	Posted - Jul 03 2021 : 04:06:51 Hi Nigel, do you have some of those "unloadable" example files (reported as ioUnknown), so I can experiment with them?
xequte	Posted - Jul 03 2021 : 00:46:57 Yes, though the risk with ffFallbackToExtension is that a file that has an invalid extension (such as a text file with a .JPEG extension) will be reported as loadable (ioJPEG). If you use ffContentOnly: Result := iexBitmaps.FindFileFormat(aFilePath, ffContentOnly) <> ioUnknown; Then the file is almost certainly loadable by ImageEn (though there will be a small number of file types like some DICOM that will be reported as ioUnknown, but are actually loadable).

PeterPanino	Posted - Jul 02 2021 : 05:49:18 Is this the most efficient simulation of such a function?: function TformMain.ImageFileCanBeLoaded(const aFilePath: string): Boolean; begin Result := iexBitmaps.FindFileFormat(aFilePath, ffFallbackToExtension) <> ioUnknown; end;
