I havent actually tried it in * combination with the gz plugin, but it works with all other file * types. I will eventually get around to making sure it works with * gz. * * To use: 1) image->File->mail image * 2) when the mail dialog popups up, fill it out. Only to: * and filename are required note: the filename needs to a * type that the image can be saved as. otherwise you will * just send an empty message. * 3) click ok and it should be on its way * * * NOTE: You probabaly need sendmail installed. If your sendmail is in * an odd spot you can change the #define below. If you use * qmail or other MTA's, and this works after changing the * MAILER, let me know how well or what changes were needed. * * NOTE: Uuencode is needed. If it is in the path, it should work fine * as is. Other- wise just change the UUENCODE. * * * TODO: 1) the aforementioned abilty to specify the * uuencode filename *done* * 2) someway to do this without tmp files * * wont happen anytime soon* * 3) MIME? *done* * 4) a pointlessly snazzier dialog * 5) make sure it works with gz * * works for .xcfgz but not .xcf.gz * * 6) add an option to choose if mail get * uuencode or not (or MIME'ed for that matter) * 7) realtime preview * 8) better entry for comments *done* * 9) list of frequently used addreses * 10) openGL compliance * 11) better handling of filesave errors * * * As always: The utility of this plugin is left as an exercise for the reader * */ #include "config.h" #include #include #include #include #include #include #include #include #include #include #include #include #include "libgimp/stdplugins-intl.h" /* GdkPixbuf RGBA C-Source image dump 1-byte-run-length-encoded */ #ifdef __SUNPRO_C #pragma align 4 (mail_icon) #endif #ifdef __GNUC__ static const guint8 mail_icon[] __attribute__ ((__aligned__ (4))) = #else static const guint8 mail_icon[] = #endif { "" /* Pixbuf magic (0x47646b50) */ "GdkP" /* length: header (24) + pixel_data (473) */ "\0\0\1\361" /* pixdata_type (0x2010002) */ "\2\1\0\2" /* rowstride (64) */ "\0\0\0@" /* width (16) */ "\0\0\0\20" /* height (16) */ "\0\0\0\20" /* pixel_data: */ "\261\0\0\0\0\3\0\0\0e\0\0\0\377\40\40\40\377\211\0\0\0\377\1\0\0\0e\203" "\0\0\0\0\2\0\0\0\377ttt\377\211\365\365\365\377\2DDD\377\0\0\0\377\203" "\0\0\0\0\15\0\0\0\377\365\365\365\377ggg\377\361\361\361\377\343\343" "\343\377\365\365\365\377\343\343\343\377\363\363\363\377\343\343\343" "\377\330\330\330\377VVV\377\270\270\270\377\0\0\0\377\203\0\0\0\0\15" "\0\0\0\377\365\365\365\377\343\343\343\377hhh\377\363\363\363\377\345" "\345\345\377\362\362\362\377\343\343\343\377\326\326\326\377YYY\377\326" "\326\326\377\260\260\260\377\0\0\0\377\203\0\0\0\0\2\0\0\0\377\365\365" "\365\377\202\343\343\343\377\11eee\377\363\363\363\377\343\343\343\377" "\333\333\333\377YYY\377\343\343\343\377\323\323\323\377\260\260\260\377" "\0\0\0\377\203\0\0\0\0\15\0\0\0\377\365\365\365\377\343\343\343\377\336" "\336\336\377\177\177\177\377YYY\377\365\365\365\377YYY\377nnn\377\330" "\330\330\377\306\306\306\377\257\257\257\377\0\0\0\377\203\0\0\0\0\4" "\0\0\0\377\365\365\365\377\340\340\340\377yyy\377\202\343\343\343\377" "\1YYY\377\202\333\333\333\377\4eee\377\266\266\266\377\257\257\257\377" "\0\0\0\377\203\0\0\0\0\15\0\0\0\377\365\365\365\377{{{\377\343\343\343" "\377\323\323\323\377\334\334\334\377\325\325\325\377\333\333\333\377" "\324\324\324\377\270\270\270\377JJJ\377\265\265\265\377\0\0\0\377\203" "\0\0\0\0\3\0\0\0\377ZZZ\377\252\252\252\377\203\253\253\253\377\1\252" "\252\252\377\202\254\254\254\377\4\255\255\255\377\262\262\262\377DD" "D\377\0\0\0\377\203\0\0\0\0\1\0\0\0e\213\0\0\0\377\1\0\0\0e\262\0\0\0" "\0"};
