Is there a utility to create blank images?

Question

I'm looking for an xpm icon to use as a placeholder until I make something better.

Are there any linux command line tools that create blank images of specified dimensions? Like people use touch to create blank text files.

Answer 1

The convert command from ImageMagick can be used:

To create a 32x32 image with a white background:

convert -size 32x32 xc:white empty.jpg

To create a 32x32 image with a transparent background:

convert -size 32x32 xc:transparent empty2.jpg

Answer 2

ImageMagick's convert can do this.

Here you go:

Imagemagick does it all for you. You can specify size, colour and filetype. Also you can put it through 'passthru' or 'exec' in your code or run the php module version.

Answer 4

You can use convert -size 123x456 xc:white x.png. convert is part of ImageMagick.
