Amaya allows you to include vector graphics in Web pages, following the Scalable Vector Graphics (SVG) specification. SVG elements are handled as structured components, in the same way as HTML elements. Therefore, you can manipulate SVG graphics in the same way you manipulate other parts of HTML documents. All editing commands provided by Amaya for handling text are also available for graphics. There are also some additional controls for entering SVG elements.
To create a new SVG element in a document, just move the insertion point
(the caret) to the position where you want to insert it, and then click the
Graphics button
.
The Graphics button displays a palette that stays on the screen until you
click the Done button. Just choose the element you want to
create. The available graphics elements are:
line in SVG,
rect in SVG with no rx or
ry attributes,
rect in SVG,
circle in SVG,
ellipse in SVG,
polyline in SVG,
polygon in SVG,
foreignObject in SVG,
text in SVG
When you select a shape in the palette and the selection is in the HTML structure of the document, Amaya creates a new SVG element just at the beginning of the current selection and the selected shape into this new SVG. Amaya generates SVG drawings as blocks, between paragraphs. If you wish to display a drawing inline, today you have let Amaya creates it between paragrahs then edit the source code to move it.
When the current selected element is a SVG element, the new shape is added to the current SVG drawing. The new created shape is added after and then can overlap previous ones.
The creation of a shape needs some direct interactions with the user:
You can insert an image within a SVG drawing. Choose Image
from the Types menu or click on the image
button from the button bar and proceed in the same way as in HTML.
For inserting a mathematical expression into a SVG drawing, you have just
to click in the Math palette when the selection in within a
SVG. Amaya will generate a SVG foreignObject to embed the MathML
markup.
With Amaya, you can paint (i.e., fill or stroke) SVG elements with a single
color. The default fill color is black and the
default stroke color is transparent. But you can
change these values:
fill and
stroke (example, fill=" #C8FF95"
stroke=" #000000"),style with CSS properties
fill and stroke (example, style="fill: #C8FF95; stroke:
#000000").The palette displayed by the menu entry Style/Colors
allows you to generate the SVG style attribute. In the Amaya
palette, a click with the left mouse button generates the stroke property and
a click with the middle or right mouse button generates the fill property.
A SVG text is considered as a graphic shape, so the
fill property paints the character contents and the
stroke property paints the character border. Amaya applies the
fill property to characters, but not the stroke property. That explains why a
click with the left mouse button has no immediate effect, and a click with the
middle or right mouse button paints the text element.
