forcing output file format on stdout

[mobu]

Hello,

I am using the convert program to run image files through a pipe line:

Code: Select all

previous_stage_in_pipeline | convert -filteroptions | next_stage_in_pipline

convert makes this easy, just by specifying '-' as the input and output filenames.

However, in all the examples I can find, the file formats are implied by the filename, and in my case I am not handling any filenames, just the data. How can I force the output file format to something specific? For example, how do I force the output to be a JPG if there is something like a PNG on the input side of the pipeline?

Try jpeg:-.

Seems to work! Thanks for the tip!
