Hi,
I have a question regarding tiling rectangular areas
of a drawable.
In the course of writing a widget I have been considering the question of
tiling a rectangular area of a drawable. I have tried the obvious way of
doing this, i.e., setting the tile attribute of a gc, the ts_x_origin,
ts_y_origin, and the fill style to FillTiled, and the not-so-obvious way,
i.e., doing it yourself.
In both cases I was using a Pixmap to tile a drawable. I found (much to my
surprise) that the not-so-obvious way was MUCH faster (one my Sparcstation
1) with an area about twelve times the area of the tile. This seems bizzare
to me, after all the obvious way requires one trip to the server, while the
not-so-obvious way requires many trips.
Has anyone else noticed such behaviour, or have I most likely overlooked
something?
The code is in a widget I am writing, so I do not include it here, however,
I will go off now and try and reproduce this in straight Xlib calls. In the
meantime, if anyone has advice, flames (:-), etc., I'll be happy to receive
them, and will post a summary to the net if there is interest

(later....)
I've written two raw Xlib programs to demonstrate the problem. (Compile
with -lX11).

Subject: XFillRectangle with Tile Vs Manual Tiling
Reply-To: afzal@cuisun.unige.ch
(not sure if this got posted)
Hi,
I have a question regarding tiling rectangular areas
of a drawable.
In the course of writing a widget I have been considering the question of
tiling a rectangular area of a drawable. I have tried the obvious way of
doing this, i.e., setting the tile attribute of a gc, the ts_x_origin,
ts_y_origin, and the fill style to FillTiled, and the not-so-obvious way,
i.e., doing it yourself.
In both cases I was using a Pixmap to tile a drawable. I found (much to my
surprise) that the not-so-obvious way was MUCH faster (one my Sparcstation
1) with an area about twelve times the area of the tile. This seems bizzare
to me, after all the obvious way requires one trip to the server, while the
not-so-obvious way requires many trips.
Has anyone else noticed such behaviour, or have I most likely overlooked
something?
The code is in a widget I am writing, so I do not include it here, however,
I will go off now and try and reproduce this in straight Xlib calls. In the
meantime, if anyone has advice, flames (:-), etc., I'll be happy to receive
them, and will post a summary to the net if there is interest
-Afzal Ballim
(later....)
I've written two raw Xlib programs to demonstrate the problem. (Compile
with -lX11).

Hi,
I have a question regarding tiling rectangular areas
of a drawable.
In the course of writing a widget I have been considering the question of
tiling a rectangular area of a drawable. I have tried the obvious way of
doing this, i.e., setting the tile attribute of a gc, the ts_x_origin,
ts_y_origin, and the fill style to FillTiled, and the not-so-obvious way,
i.e., doing it yourself.
In both cases I was using a Pixmap to tile a drawable. I found (much to my
surprise) that the not-so-obvious way was MUCH faster (one my Sparcstation
1) with an area about twelve times the area of the tile. This seems bizzare
to me, after all the obvious way requires one trip to the server, while the
not-so-obvious way requires many trips.
Has anyone else noticed such behaviour, or have I most likely overlooked
something?
The code is in a widget I am writing, so I do not include it here, however,
I will go off now and try and reproduce this in straight Xlib calls. In the
meantime, if anyone has advice, flames (:-), etc., I'll be happy to receive
them, and will post a summary to the net if there is interest

(later....)
I've written two raw Xlib programs to demonstrate the problem. (Compile
with -lX11).

My environment is the MIT sample server on a Sun-3/60 with a "hi-res" (1600x1280) display. You don't say whether your SS1 is color or not, but I would guess not, because you're missing the last argument to XCopyPlane. (You also don't say whose server you're using, but I suspect it doesn't make much difference.) Also note that the semantics of FillTiled are such that you should always be using XCopyArea in the second program, to be fair. However, on a one-bit display, you are, and the speed difference is still present. In the interests of fairness, I also tried copying the XChangeGC call into the outer loop in the second program. It made no visible difference. Out of curiousity, I did delete the if and try it on a color machine, a color SPARCstation 1+. The speed difference is essentially gone. However, the XFillRectangle code doesn't even work! (It looks as though something is getting confused with negative values somewhere. I shall be submitting a bug report....) Aside from that, the XFillRectangle code is aesthetically much nicer; the fills proceed in a visually more even fashion. I'd say the FillTiled code in the server needs work. It really should never be slower than doing many individual copies.... der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu

Tiling operations are very complicated and cover a wide range of potential usages. The most common tiling operations use small tiles (< 32x32) to fill areas on the screen. The R4 server optimizes this case, and leaves the other cases to wither with pretty horrible code. The problem with other tile sizes is that the server needs to choose to either emulate bitblt code, and plop down repeated blocks of the tile, or to attempt something different. For smaller tiles, emulating bitblt is painfully slow; the frame buffer is repeatedly modified at the same addresses to lay down those bits. Larger tiles could make effective use of the bitblt code without the performance penalty So, while it may seem like the server should always choose the 'fastest' way of doing something, it is also the case that the time spent optimizing various of these algorithms is better spent doing something else. You could spend an arbitrary amount of time optimizing various potential combinations of client requests; this one has never reached the top of the heap. Yes, the R5 server will do the tiling case faster than the bitblt case on color frame buffers. I fixed your example which uses CopyArea to work correctly on CFB (removing the CopyPlane call and disabling GraphicsExpose events) and measured: 24 seconds Tiling code 34 seconds Bitblt code I sped this up several months ago so that xphoon would run reasonably fast on my display. Besides, if everything went as fast as it could, I'd be out of work, wouldn't I.
