Red overlays for editing
Note that the top ordinate is the position of the top of the overlay from the top of the image and the left ordinate is the left of the overlay from the left of the image. The presentation will return to normal when the grid parameter is removed or set to a value other than yes. The coordinate grid is 900 x 900, so if the image is set to be smaller than this, the page content may be off scrolled, etc. To assist in determining the position of each overlay a coordinate grid showing from the left ordinates and from the top ordinates can be displayed by setting the grid parameter to yes: Either spelling can be used for any parameter value or any parameter name. This is a colour/color friendly template. The overlay tip for an overlay with double quotes in it should always be set explicitly when form = text or when form = colour are used. To include a double quote use its HTML coding, '.ĭouble quotes are always allowed in the overlay, but if the overlay tip for that overlay is not set separately, the tip, which defaults to the same text as the overlay, will probably not display correctly. However, overlapping ranges might result in unexpected behaviour, which might not be stable with any template updates.ĭouble quotes in pop up tips for overlays ĭouble quotes, ", cannot be placed in overlay tips when form = text or when form = colour are used. This is either a deficiency or a feature depending on how you look at it. Legend start and end ranges can be overlapped. If legend titles are provided without a corresponding start or end and the template cannot explicitly determine one from an adjacent legend then it will "guess" and unexpected results might be produced, which might not be stable with any template updates. While the template will handle missing set overlay values at the start, that is the first overlay item does not have to be overlay1, the template treats intermediate missing overlays as though they exist for column balancing, and it does not allow for any text wrapped new lines within an overlay item's text. If an end overlay item is specified for any explicit grouping and there is no following explicit grouping, then the remainder of the overlay items are displayed as an untitled grouping after the last explicit group.īy setting the start of the first explicit grouping after the first overlay item and the end of the sixth explicit grouping before the last overlay item, effectively 8 groupings can be configured, the first and eighth being untitled.ĭeficiences Automatic column balancing If the start overlay item for the first explicit grouping is after the first overlay item then the overlay text items from the first overlay up to but not including the first explicitly grouped overlay item are displayed as an untitled grouping before the first explicit group. The number of overlay legend text items in each column is automatically balanced by the template across the columns within each legend grouping. Each explicit legend grouping can optionally be given a title. The legend can be grouped into groups of overlays, explicitly up to 6 groups. The legend can be turned off by setting the number of columns to '0'. See Spider's main organs below for example.Ī legend of the text for each overlay is displayed by default, in 3 columns, under the image. This is particularly useful when the image itself already includes the overlays and-or colour tagging.
The overlays can be turned off by setting overlay to 'no', which will result in the only the image and legend being displayed. Each overlay inherits its colour from the previous overlay, so only the first of any colour grouped overlays needs to have its colour set.Įach overlay is configurably wikilinkable by the template. The colour of each overlay can be individually set. Typical colours of overlays are as follows: Any overlay can be placed over the image up to 3 times, to indicate multiple locations of the same feature in the image. Up to 30 overlays can be positioned over the image.
