#X text 50 12 Synopsis: [pix_share_write];
#X text 29 56 Description: write pixels to a shared memory region;
#X text 63 241 <i:ID> <i:width> <i:height> <colorspace>;
#X text 446 284 see also:;
#X text 15 181 [pix_share_write] needs to know the image-dimensions
(and color-space) in advance. The color-space can be given as a symbol
("RGBA" \, "YUV" \, "Grey") or as pixel-width (4 \, 2 \, 1);
#X text 18 72 [pix_share_write] will create (if needed) a portion of
shared memory - identified by a given ID - where it can write pix-data
into. This data can then be read via one or more [pix_share_read] objects
(referencing to the same ID).;
#X text 18 127 [pix_share_write] and [pix_share_read] need not be in
the same instance of Pd. However all objects need to have access to
the same memory (they probably need to run on the same computer);
#X text 446 347 in a different Pd instance on your;
#X text 447 361 machine to see the effect.;
