Halllo together!
I would like to effect the following quick, dirty and if possible with freeware:
One has a scanned text of a highly confidential document from which you would like to highlight a particular passage. This is usually achieved even with a light ruler which makes the interesting Textppassage hell, everything else appears about 50% dark covered.
Ifs then will be especially dramatic, with a sort of magnifying glass function is the relevant text excerpt or zoomed to full screen.
My question: What tools do I get the general point (highlight / zoom), and are there synonymous freeware alternatives?
Many thanks in advance
Markus

You can do this with
Avisynth (www.avisynth.org). A quick & dirty script might look like this:
[code: 1:5 aa87a9aac]
# Main video capture, here's a 1024x768 screenshot as a "document"
image = ImageSource ( "Image1.bmp", 1, 1, 25, true, false, "RGB24")
# Make Longer
clip = image
clip = clip + clip + clip + clip + clip
clip = clip + clip + clip + clip + clip
clip = clip + clip + clip + clip + clip
clip = clip + clip + clip + clip + clip
# Screen capture, screen is a 1024x768 SW-Picture with the light ruler
mask = ImageSource ( "Mask1.bmp", 1, 1, 25, true, false, "RGB24")
# Mask over the main video basket
mix = Overlay (clip, mask, mode = "multiply", opacity = 0.5)
# Zoom
Animate result = (mix, 0, 625, "BilinearResize" 1024,768,0,0,1024,768, 1024,768,300,400,160,120)
return result
[/ code: 1:5 aa87a9aac]
The two images you can make your own instead, or incorporate your video (look up function AviSource)
The script can be viewed or will be imported with an Avisynth-compatible video application (eg VirtualDub) and cut, changed and stored as compressed next video in Avisynth installed in Media Player.
Good luck
The thick Stefan

... ..... photoshop or similar program to take ... Picture-neck brighten or darken the text according to rest and do a simple pan across Stillimage (which is actually with) almost every single scnittprogramm.
