. i'm working on my second interactive video piece called 'collage'

. it lets the user move still frames of a video comprised of images/webding fonts and 'place' them on in the composition. when they're ready to go to the next image, i want to grab a screen capture, then load that into the next clip layer and let them choose another image.

. is there a way to get the file location and file name of the image that i just captured with direct_snapshot_previewWindow ?

. i know i can hardcode the directory that i set in preferences then import the os libraries in a module and grab the file name, then use direct_media_change to pull them image in and reset the media on the clip layer, but i'm looking for a slightly more elegant way of doing this.

. or is that the elegant way to do it?

. ok, for the curious, this is my solution

. in Init()
import os

. then i have a button that grabs the current preview and runs saveLiteToImage()

. variable previously set:
capturePath = '/Users/anomad/Desktop/collage' -- this mirrors the save preview files location in preferences
workMedia = 2 -- the media id i'm going to load this into (bank 1, top row, 3rd from left)
currentWork = 4 -- the clip layer i want the image to show up in. the user is manipulating layer 3. (layers 1 and 2 will have how to and other prompts being displayed)

Code: Select all

def saveLiveToImage() :
   modul8.setValue('direct_snapshot_mainOutput',1,0)
   if os.path.isdir(capturePath) :
      for fn in os.listdir(capturePath):
         myFN = capturePath+"/"+fn
      print myFN
      loadVal = workMedia,myFN
      modul8.setValue('direct_media_change',loadVal,currentWork)
      modul8.setValue('ctrl_layer_media',workMedia,currentWork)

. so, i loop through the directory to get the last item (sorted by name, i'm guessing) - then i load that into the media set and reset currentWork layer to the new media

. it works. sort of... to make the program interesting, i'm allowing the user to rotate, scale and move the pieces.

. to scale the pieces - i first set 'ctrl_layer_scale_factorUniform' to 4. then, the module changes 'ctrl_layer_scale_uniform' to change the size

. and this causes some interesting behaviour

. here is a screen cap of before i capture the preview and save it as a .png



. looks good, so i call my routine above, it saves it into the next layer and shows me the exact same image, in the same location.



. this is video image on layer 3 (scale_uniformFactor=4), still image i just captured on layer4 (scale_uniformFacor=2)

. the capture appears to be smaller....

. and continual saving of the image w/o moving the top layer produces a getting smaller effect



. is this expected behaviour ? or is modul8 not taking into account a layer might be zoomed when it captures the preview?

. hmmm. if i set the ctrl_layer_scale_factorUniform equal to 2 on both layers, set the preview to 4:3, limit screen cape size to 1024x768 and go full screen @ 1024x768 and do the screen caps, they only shrink by a couple pixels each time.
