[GEM-dev] pix_write \ pix_image

[Фывапр Олджэвич]

Hi again..! 

1) the [pix_writer] seems to work, but it makes pictures like this only (in attach) - so it tripples them.. i found a help patch on github - nothing said about it.. 

do you know this bug ?  how can i fix it ?

2) IOhannes said, that it is an abstraction, but i can't open it... 

3) finally there's just one inlet and in the help patch nothing said about position and size (this is not the crutual for my case, but anyway)

thanks !

How can i do it ???
