When I try to read a file and the path of that file contains a folder which contains a french letter (for instance 'é' in its name) I get this exception :
No such file or directory @ error/blob.c/OpenBlob/2589

Magick++ seems to not support french letters in the path or file name.
Is there any ...

OK. Thanks.
BTW, have you added support of shadow to Magick++ ?
because I'm using MagicWand just for the shadow function. For everything else I use Magick++.

We got it wrong. You want Magick::Image::endian().

Well this is for magick++. I have used the following code :

Image p;
p.endian(LSBEndian);
p.read(filename);


And it works great, but now I'm looking for the equivalent when using magickwand...

I have the following code :

MagickWand * pic ...

I suspect the following error...

Compiler Error C2079

C2079 can also occur if you attempt to declare an object on the stack of a type whose forward declaration ...

In options.h there is the following comment...
Is it the reason I can't use it ???

hum... I get a message "use of non defined type "Magick::Options"
I see the class Options in Options.h but seems like it is not defined ???

In magick++ there is a method to specify the endian.
Is there an equivalent with MagickWand ?

Thanks a lot !

You were right. It works with version 6.7.5.0. Thanks.

However, I have noticed an important change in comparison with version 6.7.3.8.

I'm using 16 bits depth quantum and PixelPacket to have acces to pixel colors.
When working with jpeg or 8 bits tif, the color is stored in the low order byte of ...

OK. Thanks. I will try and let you know if it was indeed a version problem.
I'm using 6.7.3.8.

No idea ?
Can someone please try with the tif file and tell me if it crashes too ?
Thanks.

This is just a code to show the problem (normalyt it's 3 different files...)


Image p1("C:\\image.tif");
::AfxMessageBox("p1 ok");

Image p2("C:\\image.tif");
::AfxMessageBox("p2 ok");

Image p3("C:\\image.tif");
::AfxMessageBox("p3 ok");


"p1 ok" is displayed always
"p2 ok" is sometimes ...

Thanks for the answer. Do you know any library I can use for this ?

I have a tif file which I access and modify through a PixelPacket * pointer.
When I save the file after modification, the exif data contained inside the tif file are lost.
Is there any way to keep the exif data ?

I have a jpeg file which I access and modify through a PixelPacket * pointer.
When I save the file after modification, the thumbnail contained inside the file is not updated.
Is there any method which allows to update the internal thumbnail of a jpg file ?

The same program with a tif file, works ...
