GD::Image::Orientation 0.05

GD::Image::Orientation is a Perl extension for managing a GD::Images vertical or horizontal orientation (shapewise). SYNOPSIS use GD::Image::Orientation; for(@images) { my $img = GD::Image->new($_) or die $!; $dbh->do("INSERT INTO photogallery.metainfo (Id,Orientation,File) VALUES (NULL,$img->isvertical,$dbh->quote($_))") or die $dbh->errstr; } Adds functionality to GD by adding class methods to determine orientation in boolean terms or in a string. Also included methods to set an images orientation; isvertical() $img->isvertical() Returns true if an images height is greater than its width. Call it with a true argument: $img->isvertical(1) and it returns true if an images height is greater than its width or it is square. ishorizontal() $img->ishorizontal() Returns true if an images width is greater than its height. Call it with a true argument: $img->ishorizontal(1) and it returns true if an images width is greater than its height or it is square. issquare() Returns true if an images width and height are the same. orientation() Returns a string describing its orientation in English. It returns horizontal, vertical, or square print The image you uploaded is . $img->orientation . " n"; vertical() If the image is horizontal it is rotated 90 degrees clockwise to become vertical. Call it with a true argument and its rotated 90 degrees counter clockwise to become vertical. It returns a new GD::Image object if modified or the original object if its already vertical or square. my $vert_img = $img->vertical; # rotate $img clockwise 90 degrees if its horizontal my $vert_img = $img->vertical(1); # rotate $img counter clockwise 90 degrees if its horizontal $img = $img->vertical; # rotate $img clockwise 90 degrees if its horizontal, modifying the original object If the second argument is true it will rotate it even if its sqare: my $vert_img = $img->vertical(0,1); # rotate $img clockwise if its horizontal or square my $vert_img = $img->vertical(1,1); # rotate $img counter clockwise if its horizontal or square horizontal() If the image is vertical it is rotated 90 degrees clockwise to become horizontal. Call it with a true argument and its rotated 90 degrees counter clockwise to become horizontal. It returns a new GD::Image object if modified or the original object if its already horizontal or square. my $hori_img = $img->horizontal; # rotate $img clockwise 90 degrees if its vertical my $hori_img = $img->horizontal(1); # rotate $img counter clockwise 90 degrees if its vertical $img = $img->horizontal; # rotate $img clockwise 90 degrees if its vertical, modifying the original object If the second argument is true it will rotate it even if its square: my $vert_img = $img->horizontal(0,1); # rotate $img clockwise if its vertical or square my $vert_img = $img->horizontal(1,1); # rotate $img counter clockwise if its vertical or square.
