Using "convert -interlace ..." on files with no such support

Post by mattalexx »

I'm using the cli tool to create thumbnails. I want to add "-interlace none" to the convert command. For which image types is this command valid? Will I get an error if I execute it on a wrong image file type?

I don't know all the file types that support interlacing, but adding -interlace none to your command should not hurt. I tried it on jpg, png, tif, gif and bmp and no complaints.

For image formats that support interlacing (gif and png and others), see

http://en.wikipedia.org/wiki/Interlace_(bitmaps)

I don't know whether IM supports interlacing in each of them
