Description
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
These four pixel formats are packed raw sRGB / Bayer formats with 10
|
2016-06-20 22:53:55 +07:00
|
|
|
bits per sample. Every four consecutive samples are packed into 5
|
|
|
|
|
bytes. Each of the first 4 bytes contain the 8 high order bits
|
|
|
|
|
of the pixels, and the 5th byte contains the 2 least significants
|
|
|
|
|
bits of each pixel, in the same order.
|
2016-06-30 20:18:56 +07:00
|
|
|
|
|
|
|
|
Each n-pixel row contains n/2 green samples and n/2 blue or red samples,
|
|
|
|
|
with alternating green-red and green-blue rows. They are conventionally
|
|
|
|
|
described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example

|
|
of a small V4L2_PIX_FMT_SBGGR10P image:

Each cell is one byte.

[media] docs-rst: add tabularcolumns to all tables
LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.
As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:
my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
if (!$table_header) {
$has_cols = 1 if (m/..\s+tabularcolumns::/);
if (m/..\s+flat-table::/) {
$table_header = 1;
$header = $_;
next;
}
$out .= $_;
next;
}
$header .= $_;
@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
if (m/^\n$/) {
if (!$has_cols && @widths) {
my ($tot, $t, $i) = (0, 0, 0);
foreach my $v(@widths) { $tot += $v; };
$out .= ".. tabularcolumns:: |";
for ($i = 0; $i < scalar @widths - 1; $i++) {
my $v = $widths[$i];
my $w = round(10 * ($v * $line_size) / $tot) / 10;
$out .= sprintf "p{%.1fcm}|", $w;
$t += $w;
}
my $w = $line_size - $t;
$out .= sprintf "p{%.1fcm}|\n\n", $w;
}
$out .= $header;
$table_header = 0;
$has_cols = 0;
$header = "";
@widths = ();
}
}
print $out;

[media] v4l: doc: Remove row numbers from tables
Shorten the tables by removing row numbers in comments, allowing for
later insertion of rows with minimal diffs.
All changes have been generated by the following script.

if fname.endswith('hist-v4l2.rst'):
