|
vertical starting position, but clamps its at 0. Therefore vertical
|
|
offsets 0 through 146 (@300 dpi) get all mapped onto the same
|
|
physical starting position: line 0. Then, starting from 147, the
|
|
offsets get mapped onto successive physical lines:
|
|
y line
|
|
0 -> 0
|
|
1 -> 0
|
|
2 -> 0
|
|
...
|
|
146 -> 0
|
|
147 -> 1
|
|
148 -> 2
|
|
...
|
|
Since a preview scan is typically made starting from y = 0, but
|
|
partial image scans usually start at y >> 147, this results in a
|
|
discontinuity in the y to line mapping, resulting in wrong offsets.
|
|
To prevent this, we must always add (at least) 146 to the y
|
|
offset before it is sent to the scanner. The scanner will then
|
|
map y = 0 (146) to the first line, y = 1 (147) to the second line,
|
|
and so on. Any distance that is then measured on the preview scan,
|
|
can be translated without any discontinuity.
|
|
|
|
However, there is one complication: during a preview scan, which
|
|
normally covers the whole scan area of the scanner, we should _not_
|
|
add the offset because it will result in a reduced number of lines
|
|
being returned (the scan height is clamped in
|
|
pixma_check_scan_param()). Since the frontend has no way of telling
|
|
that the scan area has been reduced, it would derive an incorrect
|
|
effective scan resolution, and any position calculations based on
|
|
this would therefore be inaccurate.
|
|
|
|
To prevent this, we don't add the offset in case y = 0, which is
|
|
typically the case during a preview scan (the scanner effectively
|
|
adds the offset for us, see above). In that way we keep the
|
|
linearity and we don't affect the scan area during previews.
