Hi,

Any possibility of being able to view SVG files?

Thanks,

Hi Ken

SVG can be loaded (as a rasterized bitmap) using the ImageMagick plug-in:

Hi Nigel,

Thanks. Do the dll's just have to be in the exe folder and do I need all of them to view the svg in the MView or do I need to configure the MView in any way?

Thanks,

Ken R

Hi Ken

You just need to add all of the files in the ImageMagick zip to your EXE folder.

For completeness, you should also explicitly register the plug-in when your app starts:

Hi Nigel,

I have copied all dll's to the exe folder and have included:

IEGlobalSettings().RegisterPlugIns([iepiImageMagick]);
if not (iepiImageMagick in IEGlobalSettings().ActivePlugIns) then
ShowMessage('ImageMagick not found!');

and I do not get a message so must be registered but images are not appearing in the MView. I am using:

MView.LockUpdate;
MView.FillFromDirectory(MyFolder,TIEFolderFileTypes.iefAllImages);
MView.UnLockUpdate;

Regards,

Hi Nigel,

Are we talking cross-purposes here? The ImageMagick demo does not use a TImageEnMView!

Hi Ken

Can you confirm that SVG types display for you in that demo?

Thanks Ken,

Looks like TImageEnMView is not detecting SVG as a known load extension, unless DetectFileFormat is true.

We'll have a fix in the next update. Meanwhile you can just enable the DetectFileFormat parameter:

ImageEnMView1.FillFromDirectory( IEFolderTree1.Folder, -1, False, '', True, '', False );

Also note that SVG loading is now automatically supported on Delphi 12 and newer if you add Vcl.Skia to the uses clause of any unit in your project.
