I've created a JIRA here
http://jira.openlaszlo.org/jira/browse/LPP-10093 for the embedAsCFF
attribute handling. I have that working already locally for
<font name="LibertineRegular" src="LinBiolinum_r.otf" embedascff="true" />,
and I can use rotated text with a TextFlow component. Text quality
looks very good. But I have a few questions:
1) What should the name of the property be? I suppose embedascff would
be the best choice.
2) How should multiple fonts be treated? Should the embedascff be set
on the font tag, or the face tag (less optimal in my eyes)?
<font name="myfont" embedascff="true">
<face src="myfont.otf" style="plain" />
<face src="myfont-bold.otf" style="bold" />
<face src="myfont-ital.otf" style="italic" />
<face src="myfont-bita.otf" style="bold italic"/>
</font>
3) How is the usage of CFF fonts going to affect DHTML font embedding?
Haven't investigated, yet.
4) Compiler implementation question:
What is the org.openlaszlo.compiler.Canvas.mInfo element used for?
Does the new property 'embedascff' need to be added to the mInfo
element, e.g.
File: org.openlaszlo.compiler.FontCompiler#compileFont
private void compileFont(String name, Element element) {
String style = element.getAttributeValue("style");
try {
String path = mEnv.resolveReference(element).getAbsolutePath();
String embedAsCFF = null;
if (mEnv.isCanvas()) {
Element info = new Element("resolve");
info.setAttribute("src", element.getAttributeValue("src"));
info.setAttribute("pathname",
mEnv.resolveReference(element).toString());
embedAsCFF = element.getAttributeValue("embedascff");
if (embedAsCFF == null) {
// Default value should be false to support embedded
fonts in Flash TextField components.
// See http://jira.openlaszlo.org/jira/browse/LPP-9140
embedAsCFF = "false";
}
info.setAttribute("embedascff", embedAsCFF);
mEnv.getCanvas().addInfo(info);
}
Thanks,
Raju
