Hello,

I am currently evaluating the ImageEn library to process Canon .HIF generated pictures.
I have compiled the Magnify demo and when I try to open a sample image, the below Exception is raised:



I have noted this behavior on several other demo project.

I have attached a sample picture here to help reproducing the issue:

Hi Thomas

For HEIF files you are better to use the ImageMagick plug-in. This images loaded for me with ImageMagick (though the .HIF extension is not supported by default, so you are better to use .HEIF):

Hi Nigel,

thanks for your swift reply.

I have installed ImageMagick addon and compiled the provided demo.
Unfortunately the same expection is raised on my sample file.

I have tried to open the same .HIF file directly in ImageMagick and it opens properly.



I have then added the following code to prevent using WIC:
IEGlobalSettings().WICFileTypes:= '-';

Exception is not raised anymore but image still not loaded.

thank you for your support
regards

Thomas

Hi Thomas

Does it work if you call:
IEGlobalSettings().WICFileTypes:= '-';
ImageEnView1.IO.LoadFromFile( 'D:\IMG_0369.HIF' );

Or
ImageEnView1.IO.LoadFromFile( 'D:\IMG_0369.HIF', iomscHEIF );

How about if you change the extension to .heif?

Hi Nigel,

Same results trying your suggestions.
I have individually tested the following 4 cases, WIN10 64bits compiled with delphi 10.1 and 10.4.2:

in this case below => image is not loaded and WIC exception is raised:
IEGlobalSettings().WICFileTypes:= '-';
ImageEnView1.IO.LoadFromFile( 'C:\IMG_0369.HEIF' );


in the 3 cases below => image is not loaded and no exception raised:

IEGlobalSettings().WICFileTypes:= '-';
ImageEnView1.IO.LoadFromFile( 'C:\IMG_0369.HIF' );
----
ImageEnView1.IO.LoadFromFile( 'C:\IMG_0369.HIF', 8197 );  // iomscHEIF = 8197
----
ImageEnView1.IO.LoadFromFile( 'C:\IMG_0369.HEIF', 8197 );  // iomscHEIF = 8197

Thanks & regards

Thomas

Hmm, I'm not seeing that. What version of ImageEn is this?

HEIF support via ImageMagick was added in v10.3.5 and there have been a lot of other ImageMagick enhancements in 11.3.0.

I have finally succeed in loading my picure using (works also with .HEIF extension)

ImageEnView1.IO.LoadFromFile( 'C:\IMG_0369.HIF', 8197 )


It seems few ImageMagick's dlls were missing even if demo indicates "plugin registered".

I have also noticed that HEIF is not displayed in available format as seen below



Anyway thank you very much for your support

Best regards

Thomas
