Is there a 'Grayscale' function within the php version of ImageMagick which does the same as the command line function:

exec("convert $image -type Grayscale $outimage ")

I have been using '$im1->imagefilter(100,0,100);' but this just desaturates the image and produces a low contrast result.

thanks alan dunn

Checkout colorspace

Out of interest I have examples of operator usage with php on my website: Operators

thanks, I'll give it a go.

Do you mean in MagickWand for PHP? IMagick for PHP? or Shell ImageMagick from PHP?
