several questions on GDI+

[stephd]

Hi all,

i've several questions on GDI+ features :

* Thumbnails : The method GetThumbnailImage is great and do what i want to do EXCEPT when the original image contains a thumbnail image. In this case, the returned image is always issued from the embedded thumbnail even if the requested size is bigger than the enbedded thumbnail size... So it create a bad quality image. I tried to do the same thing but using RemovePropertyItem before calling GetThumbnailImage in order to remove all PropertyItems about thumbnail but it gives the same result. The only method i found is to use RemovePropertyItem, then save the image, reload it end then create the thumbnail but it's a little bit complicated and not nice at all... does anybody have a solution ?

* Gif encoder : The recorded gif image are not good at all. Is this a feature of gdi+ gif encoder or is there any option to set to have a correct image ?...

* Gif again : how to retrieve transparent color if any and how to set transparent color in encoding process.

thanks in advance.
