2075 |
* and FireFox 1.5 and later. Earlier versions of these browsers |
|
2076 |
* did not support plugin printing in the general sense (not just Java). |
|
2077 |
* A notable limitation of these browsers is that they handle plugins |
|
2078 |
* which would span page boundaries by scaling plugin content to fit on a |
|
2079 |
* single page. This means white space is left at the bottom of the |
|
2080 |
* previous page and its impossible to print these cases as they appear on |
|
2081 |
* the web page. This is contrast to how the same browsers behave on |
|
2082 |
* Windows where it renders as on-screen. |
|
2083 |
* Cases where the content fits on a single page do work fine, and they |
|
2084 |
* are the majority of cases. |
|
2085 |
* The scaling that the browser specifies to make the plugin content fit |
|
2086 |
* when it is larger than a single page can hold is non-uniform. It |
|
2087 |
* scales the axis in which the content is too large just enough to |
|
2088 |
* ensure it fits. For content which is extremely long this could lead |
|
2089 |
* to noticeable distortion. However that is probably rare enough that |
|
2090 |
* its not worth compensating for that here, but we can revisit that if |
|
2091 |
* needed, and compensate by making the scale for the other axis the |
|
2092 |
* same. |

2168 |
* This class can take an application-client supplied printable object |

2170 |
* The application does not need to send any postscript to this stream |
|
2171 |
* unless it needs to specify a translation etc. |
|
2172 |
* It assumes that its importing application obeys all the conventions |

|
2174 |
* Format - of the Adobe Postscript Language Reference Manual, 2nd edition. |

2175 |
* This class could be used as the basis for exposing the ability to |
|
2176 |
* generate EPSF from 2D graphics as a StreamPrintService. |
|
2177 |
* In that case a MediaPrintableArea attribute could be used to |
|
2178 |
