Re: ico decode from blob failed

magick wrote:The ICO format does not have a magic string to help identify it like JPEG or PNG does. Instead you must hint to ImageMagick the format the blob is in. Use magick("ICO") before you read the blob.
thank you so much.With your help,I have solved it successfully!

Re: ico decode from blob failed

I noticed that the difference between these two way lie in that Image constructor will call the 'void Magick::Image::read ( const std::string &imageSpec_ )'in Image.cpp while the other will call the 'void Magick::Image::read ( const Blob &blob_ )',is this the reason?some pic format can only ...

Re: problem when convert pic to webp format

I don't know much about webp format, but if it is a pixel format and not vector, then the -quality should come after reading the input image. But I am not sure that -quality is relevant to webp format -- that is I don't know if IM understands what quality means for that format. I believe that -qual...
