lightness rescaling using sigmoidal =contrast enhancement -size geometry width and height of image -solarize =threshold negate all pixels above the threshold level -splice geometry =splice the background color into the image -spread amount displace image =pixels by a random amount -strip strip image of all profiles and =comments -stroke color graphic primitive stroke color -strokewidth value =graphic primitive stroke width -stretch type render text with this font =stretch -style type render text with this font style -support factor =resize support: > 1.0 is blurry, < 1.0 is sharp -swap indexes swap two =images in the image sequence -swirl degrees swirl image pixels about the =center -texture filename name of texture to tile onto the image =background -threshold value threshold the image -thumbnail geometry =create a thumbnail of the image -tile filename tile image when filling a =graphic primitive -tint value tint the image with the fill color =-transform affine transform

-white-threshold value force all pixels above =the threshold into white -write filename write images to this file By =default, the image format of `file' is determined by its magic number. =To specify a particular image format, precede the filename with an image =format name and a colon (i.e. ps:image) or specify the image type as the =filename suffix (i.e. image.ps). Specify 'file' as '-' for standard =input or output.>>>>> But using this: [shell scriptid=3DImageMagick_convert] =/usr/bin/convert images/[filename] -resize 816x612 =images/[newfilename] [/shell]>>>>> Dosen't give me any results.>>>>> Any ideas?>>>>> Thanks a bunch,>>>>> sfb>>>>> --------------------------------------------------------- This =message is sent to you because you are subscribed to the mailing list . =To unsubscribe, E-mail to: archives: =http://mail.webdna.us/list/talk@webdna.us Bug Reporting: =support@webdna.us>>>> --------------------------------------------------------- This =message is sent to you because you are subscribed to the mailing list . =To unsubscribe, E-mail to: archives: =http://mail.webdna.us/list/talk@webdna.us Bug Reporting: =support@webdna.us>>> --------------------------------------------------------- This =message is sent to you because you are subscribed to the mailing list . =To unsubscribe, E-mail to: archives: =http://mail.webdna.us/list/talk@webdna.us Bug Reporting: =support@webdna.us>> --------------------------------------------------------->> This message is sent to you because you are subscribed to>> the mailing list .>> To unsubscribe, E-mail to: >> archives: http://mail.webdna.us/list/talk@webdna.us>> Bug Reporting: support@webdna.us>=20> ---------------------------------------------------------> This message is sent to you because you are subscribed to> the mailing list .> To unsubscribe, E-mail to: > archives: http://mail.webdna.us/list/talk@webdna.us> Bug Reporting: support@webdna.us Stephen Braun
