Thumbnail info line - displaying shapes in v2

Post by David Grundy » 31 Jan 14 16:33

In v2, the display of shapes in the thumbnail info seems to have changed from v1. Specifically, shapes which were previously displayed in full now have the bottom chopped off.

For example
Missing bottom.JPG
Missing bottom.JPG (13.18 KiB) Viewed 2002 times
These shapes displayed in v1 as partially filled octagons, but now the bottom is missing. The clearest example is that the 3rd image (rated as 2 stars) should be symmetrical top-to-bottom

Does this code need an update to display correctly in v2?

Code: Select all

%code
// 2014-01-05 v7e Take out VUTs
// 2013-08-03 v7d Add the version count to the start of the line
// 2013-07-31 v7c Change colour of Version triangles to agree with the Main version VUT colour
// 2013-07-29 v7b Show VUTs (add Camera, HDR, BW, XNoFunction)
// 2013-07-27 v7 Show VUTs (implemented using the Custom Input Fields)
// 2013-07-27 v6d Replace stars with a part-filled square
// 2013-07-13 v5b, modified colours
// 2013-06-30 v5a, split version indicator from rating stars
// 2013-06 early versions based on code by Hert

// Note to self: Colours seem to be specified as ARGB Hex

V2 has improved precision when painting custom thumb lines.

You're using vertical (y) indenting. Just remove that

Code: Select all

%code
// 2014-01-05 v7e Take out VUTs
// 2013-08-03 v7d Add the version count to the start of the line
// 2013-07-31 v7c Change colour of Version triangles to agree with the Main version VUT colour
// 2013-07-29 v7b Show VUTs (add Camera, HDR, BW, XNoFunction)
// 2013-07-27 v7 Show VUTs (implemented using the Custom Input Fields)
// 2013-07-27 v6d Replace stars with a part-filled square
// 2013-07-13 v5b, modified colours
// 2013-06-30 v5a, split version indicator from rating stars
// 2013-06 early versions based on code by Hert

// Note to self: Colours seem to be specified as ARGB Hex

var
  ACatItem: TCatalogItem;

  result := '';

  ASetRatingColor := '" pathfillcolor="' + ARatingColor + '" pathstrokestyle="solid" pathstrokecolor="' + ARatingColor + '">';

  ARatingShape1 := 'M 0,0 '; //#### First part of rating shape
  ARatingShape2 := ' L 5,5 L 0,5 L 0,0 Z'; //#### Second part of rating shape

  AVersionShape := 'M 0,0 L 1,1 L 0,1 L 0,0 Z'; //#### Triangle shape for the version indicator

  ACatItem := TCatalogItem.Create(nil);
  if Catalog.FindImageCombined (ImageItem, ACatItem, False, vptNone) then
  begin

// Number of versions

    ANumVersions := ACatItem.VersionCount+1;
    if ANumVersions = 1 then
      result := result + '<font color="#FF0000FF">';

    Case ACatItem.Rating of

    end;
    result := result + ASetRatingColor;
    result := result + ' '; //This line adds extra space
    result := result + '</font>';

  end;
  ACatItem.Free;
end;

Thanks Hert, that works.
(Easy when you know how.) :)
