[comp.windows.x] XPutImage size limit?

mvh@cfa250.harvard.edu (Mike VanHilst) (05/22/89)

Is there a limit on the number of bytes of obdata that can be sent
with a single call to XPutImage?

Under X10, several calls to XPixmapBitsPutZ were needed to draw
images in large windows without choking (at least on our Sun's).
I need to know: Can I safely send an entire image with one call?
or Is there a fixed number of bytes permitted per call? or Can the
number of bytes that can be sent be determined at run-time?

I've looked in both the Digital Press and the O'Reilly set for
this info.  Thank you in advance.

No.  XPutImage knows what the maximum request size accepted by the server is,
and will decompose the image into multiple requests automatically.
