Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".
convert -background transparent -density 72 -fill black -font Arial-Bold -pointsize 60 label:"Marcel" -write mpr:text -delete 0 <do sth else here and use mpr:text >
Then all the settings i did like background, density, font etc.. is remembered after the -delete 0. Is there a command that from there i can start a clean convert again and use the mpr:text after that?
Use parenthesis and add at the beginning before the first parenthesis -regard-parenthesis
convert -regard-parenthesis \( ..... \) .....
This usually works, but for some things like -compose settings you may need to reset it again as -compose over. You can also try adding +geometry and +channel etc to reset individual setting.
Clear or reset all settings is something planned for IMv7, as is clear/reset all settings and images (sort of restart).
Otherwise you will need to use parenthesis with a -regard-parenthesis option.
IMv7 will also have a different set parenthesis to 'push/pop settings', with -regard-parenthesis merging the setting parenthesis with the image parenthesis.
