'identify -list format' output

[eldiener]

To find out about formats which ImageMagick supports and the corresponding possible format strings of the image.magick() ( Magick++ ) member function as well as the appropriate IM_MOD needed, I use the 'identify list format' command. I have one question about the output. What does an asterisk ( * ) mean after the name of a particular format ? Most formats have the asterisk after them but some do not.

At the bottom of the

• identify -list format

output you see

• * native blob support

The asterisk means the format can be read and written directly in memory without first reading/writing the file on disk. Native blob support is more efficient/faster.

Thanks, I do see the * native blob support comment on the bottom of the listing.
