problems wich need your help:
1] i don't need to show the actual video stream.. i just need to show slide

[pix_writer] will do exactly what you want: take a pix (as produced by
[pix_video]) and write it to disk.
- can i make the second gemwin for the slideshow ?
current Gem only has single window support.
- ok, i can let there be two pictures rendered together: left - the live ;
right - the slideshow... so i tried to capture only half of the window - and
the [pix_write] has the [Xpos Ypos( and the same parameteres for Size ... but
nowhere told in what numeration it is ? .. it is not the same as size and
position of geometries such are [rectangle] - so i can't easily match the area
to capture.. How can i do it ???
[translate] takes 3d-coordinates, whereas [pix_write] takes screen
coordinates (pixels). the relation between the two depends on a number
of things.
but with [pix_writer] you do not have this problem.
2] i need to make my own names for the files stored - simple like : 1.jpg ;
2.jpg ... [pix_write] doesn't allow that. it makes some difficult names.
it makes difficult names so that when you have a lot of images they are
still sorted correctly. (instead of: 1.jpg 10.jpg 100.jpg ... 199.jpg
2.jpg 20.jpg ...)
since [pix_writer] is essentially an abstraction (based on [pix_buffer]
of size 1), you can modify the naming algorithm to your liking.
- how could i then recall that files with [pix_image] ? how can i form a message with the filename
like "gem00001.tif" , where the only part will be changing the "1" .. i tryied
[makefilename], but it makes [symbols], which can't be put into [message( - it means useless for
the changing filenames on the fly ... ?
???
you seem to get something wrong here, as [makefilename]'s main purpose
it to create filenames that can be used in [messages( on the fly:
[loadbang]
|
[metro 1000]
|
[random 100]
|
[makefilename gem%5d.tif]
|
[open $1(
|
[pix_image]
