- While tinkering with a HP9000/710 and Clarity Rapport we have on loan,
- I noticed a minor annoyance in the 10.4's X server.
-
- I mailed a document to a friend on an Apollo from Clarity Rapport
- using FrameMaker's MIF format for all the artsy bits (actually the
- _only_ graphical object in the test document was a rectangle with
- rounded corners). The friend got it and opened it in Frame.
-
- The texts in the document survived the transferral unscathed, but the
- rectangle with the rounded corner (it was filled, too) lost a corner.
-
- Actually the rectangle's outline was unbroken, but the filling inside
- lacked the upper right hand corner. How odd, we thought and started
- experimenting. No, the reason was not in Clarity, the document looked
- all right when it left Clarity. No, the problem was not with the Frame
- either, as we run Frame from the same Apollo to the HP9000/710's
- screen and the document was all right.
-
- But when we tried to draw similar rectangles with rounded corners on
- the Apollo we invariably lost the upper right hand corner's color.
-
- Something similar happened with the filled arcs. Here is a crude
- reconstruction of a pair of malformed arcs:
-
-
- XXXXXXX* X#########*########
- ###XXXXX X##################
- #######XXX X#################
- * #########XX * * XX###########*###
- ###########X XXX#############
- ############X XXXXX#########
- #####*######X X*XXXXX
-
- Ummh... the # is the fill color, X is the edge of the arc and *'s are
- the resize handles.
-
- Then we took out the Sniffer and took a little peek at the traffic going
- around in the net. As one drew a rounded rectangle, Frame sent all the
- necessary bits and pieces as it should to the X server which dutifully
- managed to lose the last piece of information, the upper right hand
- corner's filling.
-
- Anyone else managed to get surprised with this?
-
- Oh, by the way, we tried it out with both the borrowed mode X server
- (about R2+) and the native R4 server, and the Apollo we experimented
- with is DN3000 with 8 Megs of memory and 1280x1024 black and white
- display.
