[interprocess] patch for shared memory initialization exception
by Paul Poulin 14 Apr '07

14 Apr '07

Interprocess, shared memory, bug & patch. Bug: A race condition exists if a shared memory segment is being created/initialized for the first time. Another attempt to open the shared memory segment concurrently results in the second process waiting for the creator to complete the initialization. When the initialization is complete the second attempt will promptly throw an interprocess_exception (corrupted_error). Fix: The patch solution is to wait for the memory segment to not be in the InitializingSegment or UninitializedSegment states. At this point if the state is anything other than InitializedSegment then throw the interprocess_exception. A proposed patch is attached.

One question: can it render text rotated by 90, 180, 270 degrees? Although the way the gil iterators work ought to make this possible, I'm not sure how you could interface between FreeType and that aspect of gil. > Yes, it supports "cleartype" and "kerning" so it will produce fonts are > equivalent to Microsoft's and > Apples. I've also added extras such as "word-wrapping" and "clipping". I hope that by "clipping" you mean that I can say "render this ten-thousand-pixel-high glypth at (0,-9900) so only the last hundred pixels are visible", and have it do so efficiently. If so, great! > Heres a complete working example of its usage. It looks rather low-level, presumably close to the native FreeType API. I'd prefer something a little more compact, e.g. image i; Font f("times",35); draw_text(i,0,0,f,"Hello World"); Unless I need to deal with the glyphs or kerning in some non-default way, I'd prefer to not see them. Presumably this sort of thing could be added on top of what you've described. > //Step 1.

boost::freetype - extension for boost::gil

Disable it if you dont want it. If "cleartype" is disabled than "freetype" just renders the glyph as a normal anti-aliased glyph. >> Can it render text rotated by 90, 180, 270 degrees? I've also played around with this, but have never had a need for it. All you have to do is rotate the glyph image buffer that is returned by freetype. You can use the freetype api's to do this or calculate it yourself. boost::gil might even have a way to rotate the image buffer, but I've not run across it. >> I hope that by "clipping" you mean that I can say "render this >> ten-thousand-pixel-high glypth at (0,-9900) so only the last hundred >> pixels are visible", and have it do so efficiently. If so, great! Kind of. It just takes care of handeling strings that are longer than the available space and optionally adds "..." at the end; or, for numeric values, "######". >> It looks rather low-level, presumably close to the native FreeType >> API. I'd prefer something a little more compact, e.g. >> image i; >> Font f("times",35); >> draw_text(i,0,0,f,"Hello World"); Its been tried many times by many developers, and it never works. I've long since given up trying to write simple wrapper classes like these for "C" api's. The best we can do is make "freetype" more "stl/boost" friendly. I've done this by converting charactar string into to a freetype glyph vector. Once this is done, the vast array of stl algorithms and iterators are available to operate on it. Example: //Step 1: Create glyphs vector gil::rgba8_pixel_t black(0,0,0,255); std::string str = "abcdef"; std::vector<boost::freetype::glyph> glyphs; std::transform(str.begin(), str.end(), std::back_inserter(glyphs), boost::freetype::make_glyph<gil::rgba8_pixel_t>(face,black)); //Step 2: Create metrics vector std::vector<FT_Glyph_Metrics> metrics; std::transform(glyphs.begin(),glyphs.end(), std::back_inserter(metrics), boost::freetype::make_metric()); //Step 3: Create kerning vector std::vector<int> kerning; std::transform(glyphs.begin(),glyphs.end(), std::back_inserter(kerning), boost::freetype::make_kerning()); //Step 4: Find last fitted glyph std::vector<FT_Glyph_Metrics>::iterator it = std::find_if(metrics.begin(),metrics.end(),kerning.begin(), boost::freetype::find_last_fitted_glyph(view.width())); //Step 5: Get the Width, Height, and Glyph Height of the string int distance = (int)std::distance(it,metrics.end()); int width = std::for_each(metrics.begin(), metrics.end()-distance, kerning.begin(), boost::freetype::make_width()); int height = std::for_each(metrics.begin(), metrics.end()-distance, boost::freetype::make_height()); int gheight = std::for_each(metrics.begin(),metrics.end(), boost::freetype::make_glyph_height()); //Step 6: calculate the x and y position int x = 0; int y = -gheight; if (align & Middle) y = (view.height()-height-gheight)/2; else if (align & FMiddle) y = (view.height()-height)/2; else if (align & Bottom) y = view.height()-height; else if (align & FBottom) y = view.height()-height+gheight; //Step 7: draw the glyphs onto the boost::gil image std::for_each(glyphs.begin(), glyphs.end()-distance, kerning.begin(), boost::freetype::draw_glyphs<>(boost::gil::subimage_view(view,x,y, view.width(),height-gheight))); Of course, this example could be wrapped into a helper function such as: boost::freetype::draw_text("abcdefg", view, face, Left|Center);

Yeah, that's cool! I'm not sure it fits the criteria I outlined though. Seems to be too complex for the cookbook? Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net

Yes, I have been thinking along the same lines. In fact I thought about this earlier today after Janek Kozicki posted asking what the focus of the proposed SoC geometry library is. I would very much like to see some 2D containers, e.g. set<point2d> and map<point2d,T>, implemented using R-trees or similar. For Boost, I presume that any such code will be expected to be "standard library like", and I was wondering how similar a set<point2d> can be to a set<int>. In particular, when I want to iterate over all the points within a rectangle, I would love to be able to write: for(set<point2d>::const_iterator i = points.lower_bound(point2d(x0,y0)); i != points.upper_bound(point2d(x1,y1)); ++i) Unfortunately it can't be quite that similar to the 1D case. Currently I have some very crude code where I define what I call a "window" into the set of points: window w(points,point(x0,y0),point(x1,y1)); for(set<point2d>::const_iterator i = w.begin(); i != w.end(); ++i) Of course, having seen Neal's message, I realise that my "window" is just a 2D range. Clearly, it would be a good plan to get basics like this (and things like a point type) thought about before Huseyin Akcan starts on his SoC work. (Huseyin, I hope you're reading this! Do please let us know what exactly you intend to do.) I have been considering writing something to implement set<point> using space filling curves. I haven't thought about it much yet and would value any suggestions. My hope is that using this technique I can adapt the standard associative containers to work with 2D points, and thereby avoid having to implement any tree stuff. In my case I'm dealing with latitude/longitude values and I think that the first thing I need is a fixed-point type, so that I can do the bit interleaving that the space filling curves need. That could make a simple self-contained Boost library - is anyone interested? Phil.
