in reply to GD::Text Problems

You should pass an instance of GD in the constructor.
use GD; use GD::Text::Align; my $gd = GD::Image->new(800,600); # allocate colours, do other things. my $align = GD::Text::Align->new( $gd #instance of GD::Image valign => 'top', halign => 'right', ); $align->set_font('cetus.ttf', 12); $align->set_text('some string'); @bb = $align->bounding_box(200, 400, PI/3); # you can do things based on the bounding box here $align->draw(200, 400, PI/3); open(JPEG,">foo.jpg"); binmode(JPEG); print JPEG $gd->jpeg(75); close(JPEG);
I personally stick to plain GD or even worse, plain gdlib code ;) </code>

    Thank you very much - I am closer than ever because it actually generates an image .. but a blank one. I'm sure its just a case of needing to specify the foreground color but all I can find in the module documentation is to set the background and fill colors
    #!/usr/bin/perl use GD; use GD::Text::Align; my $gd = GD::Image->new(150,150); $white = $gd->colorAllocate(255,255,255); # $black = $gd->colorAllocate(0,0,0); # $red = $gd->colorAllocate(255,0,0); # $blue = $gd->colorAllocate(0,0,255); $gd->transparent($white); my $align = GD::Text::Align->new( $gd, valign => 'top', halign => 'right', ); $align->set_font('cetus.ttf', 12); $align->set_text('200 Files'); @bb = $align->bounding_box(100, 100, PI/3); # you can do things based on the bounding box here $align->draw(200, 400, PI/3); open(JPEG,">foo.jpg"); binmode(JPEG); print JPEG $gd->jpeg(75); close(JPEG);

[james28909]: it is not an absolute date like "27" or "31". sometimes it is like wednesday or friday
[james28909]: and i need to format those special instances into an absolute date instead of "yesterday"
[stevieb]: ask a question on SoPW, and include at least a half-dozen examples of the input, and at least one example of expected output
[davido]: Exactly: SoPW. This isn't going to be solved easily in the CB.
[james28909]: in need "yesterday" and so on, to be absolute like "1" or "31"
[stevieb]: ...and throw some of your existing code into the equation as well, just so readers know you've given a try at it ;)
[james28909]: ok
[stevieb]: davido thanks for the link ;) I was being the typical lazy
[davido]: date parsing is hard. The more examples you can provide of the input (within reason) and expected output, the better.
[stevieb]: agreed. That's why I said at least a half-dozen. If enough of the different formats are present, the date/time folk may not have to request more. If they do, then at least there was a decent base to start with
