XpPutDocumentData ( display, drawable, data, data_len, doc_fmt, options )
Display *display;

Drawable drawable;

unsigned char *data;

int data_len;

char *doc_fmt;

char *options;


Specifies a pointer to the Display structure; returned from XOpenDisplay.
Specifies the destination drawable for rendering.
Specifies the device-specific data sent.
Specifies the number of bytes in data.
Specifies the type of data sent. See below for valid values. String limited to XPCS characters.
Specifies DDX driver dependent options. String limited to XPCS characters.


Depending on type for XpStartDoc, XpPutDocumentData has two modes of operation.

In XPDocRaw mode, XpPutDocumentData sends data directly to the output, and drawable must be None, else a BadDrawable error is generated. The X Print Server does not emit document or page control codes into the output, and data is passed through unmodified. This is useful for sending previously constructed and completed documents using the X Print Server job control and submission capabilities. The printer attribute xp-raw-formats-supported defines the valid values for doc_fmt in this mode. Unsupported values for doc_fmt cause a BadMatch error to be generated.

In XPDocNormal mode, XpPutDocumentData sends data to the X Print Server , and depending on the DDX driver implementation, integrates data into the output. The parameters doc_fmt and options describe the format of data which guides the DDX driver in interpreting data. The printer attribute xp-embedded-formats-supported defines the valid values for doc_fmt in this mode, with unsupported values for doc_fmt causing a BadMatch error to be generated.

If doc_fmt is not in either xp-raw-formats-supported or xp-embedded-formats-supported a BadValue error is generated.

Depending on the DDX driver implementation in use, XpPutDocumentData might be used, for example, to send a simple text file to a Postscript DDX driver that is capable of wrapping the appropriate document and page control constructs around the text so that it can be printed on a Postscript printer. Likewise, Encapsulated Postscript Files might be handled. Another use could be to send a TIFF file to a PCL DDX driver that can convert the image from TIFF into PCL and then integrate it into the current PCL output.

There is no limit to the value of data_len. XpPutDocumentData automatically decomposes the call into multiple protocol requests to make sure that the maximum request size of the server is not exceeded.


The value specified for drawable is not valid.
The value specified for doc_fmt is not valid for the current document type or the value specified for is not valid for the print context and print screen.
The value specified for doc_fmt is not supported.
A valid print context-id has not been set prior to making this call.
The function was not called in the proper order with respect to the other X Print Service Extension calls (for example, XpPutDocumentData prior to XpStartDoc).
