Size of segments in X-axis: L
partX
= L
totalX
/[x-(b/100)*(x-1)]
L
partX
=1024/ [3-(10/100)*(3-1)]
the size of overlapping edges was selected 10% (b=10)
L
partX
= 366 pixels
Since the size of the segments in Y-axis is the same as at the source picture, each of the 3 fixtures will project
picture with resolution of 366x768 pixels.
___________________________________________________________________________________________
Note.
On the other way round, if you need to calculate the resolution of the source picture to ensure that every
fixture will use the resolution of 1024x768 pixels, use the formula:
L
totalX
= L
partX
*[x-(b/100)*(x-1)]
for this case:
L
totalX
= 1024 *[ 3-(10/100)*(3-1
)
]
L
partX
=1024pixels
L
totalX
=2867 pixels
The source picture should have min. resolution of 2867x768 pixels.

Positions in X-axis at which single picture segments start:
L
posX
= (N
x
-1)* L
partX
*[1.0-(b/100)]
For the segment 1:
L
0X
= (1-1)* 366 *[1.0-(10/100)] = 0 pixels
N
x
= 1
For the segment 2:
L
1X
= (2-1)* 366 *[1.0-(10/100)] = 329 pixels
N
x
= 2
For the segment 3:
L
2X
= (3-1)* 366 *[1.0-(10/100)] = 659 pixels
N
x
= 3
Result: The first picture segment starts at point 0 pixels and has resolution of 366x768 pixels.
The second picture segment starts at point 329 pixels and has resolution of 366x768 pixels.
The third picture segment starts at point 659 pixels and has resolution of 366x768 pixels.
Using a suitable software you have to prepare these three pictures and copy them to the individual fixtures in
order to use them in the picture merging procedure. On the channel
Global Effect 1
select a DMX value from the
range of 11-17 DMX according as large overlapping edges you have calculated.
All other settings are the same as for standard picture merging operation.
Note.
For correct video files synchronization you have to ensure that all cutted video segments must have the
same times of video lasting.
