Which kind of quadratic curves does TrueType use? B-Spline or Bézier curve?

Hello,
I'm writing a TrueType Font parser and I have already gotten the outline data with the GetGlyphOutline function. But now I am not sure which kind of quadratic curves TrueType uses, B-Spline or Bézier curve?
The TrueType specification says "Contours are composed of straight lines and curves. Curves are defined by a series of points that describe second order Bezier-splines. "
However when I search the Internet, I find some documents says it is B-Spline.

Could somebody please tell which kind of quadratic curves Truetype uses?
Thanks in advance!

TrueType uses "Composite Bezier Curves" which are also called bezier splines or polybeziers, they are, as the spec says a second order (quadratic) curves. 
The term "bezier spline" is confusing and should be avoided, some documents will use the name to mean regular bezier curves, while others mean composite bezier curves.
Among others, Postscript, PDF, SVG, OpenType fonts, etc.  use Composite Bezier curves also.
P.S.  cubic B splines is a synonym for C2 continuous composite
cubic bezier curves.

    In users manuals on page 29 I found info that you need active 3D glasses with part number FPT-AG03.
    To be honest Im really wondering none of them was delivered with yor TV.
    Anyway, use this part number and you can order 3D glasses separately.
    Good luck and enjoy your 3D TV.

  • Which kind 3D format file can be used by LV

    I will try to make a 3D model and display it in labview, then make it can turn and mark.
    May I know which kind 3D format file can be used by LV, thanks.
    Solved!
    Go to Solution.

    I am not familiar with ASE, but can give you a little info on the other two file formats.
    STL is a simple, triangle based, file format used by many pieces of software.  All the major CAD programs can export it.  Examples are AutoCAD and SolidWorks.  Due to its simplicity, it is probably the best supported.  It is also the most commonly used file type for 3D modelling (e.g. stereolithography, selective laser sintering, 3D printing).  You can get instructions on how to convert from a .skp to a .stl here.  I have not tried them so cannot vouch for their accuracy.
    VRML format was invented for virtual reality simulations.  It has remained somewhat popular.
    A net search on any of these formats should get you a lot more information.

  • External harddrive (also, what kind of internal drive does iMac use)

    I was just wondering what kind of hard drive apple uses. I am getting an intel iMac soon and although I probably won't upgrade the harddrive now I may consider adding an external one later on.
    My question is this: How come it is $300 to add 250 gigs internally on the machine? That seems like a lot of money to me(amateur)considering you can get external drives for almost half that. Is the quality that good, or is it just a matter of engineering?
    Also, any recommendations of good external drives? Thanks!

    Dunebug38,
    Apple uses different manufacturers for their hard drives. I have a Western Digital hard drive in my iMac. I know that Apple uses Seagate hard drives also, and likely others, as well.
    I couldn't say why Apple charges so much to add the larger hard disk. Apple charges more for memory too, at least beyond 1GB.
    As for external drives, I have two Other World Computing external hard disks, both of which have an OWC case and Western Digital 300GB drives. I bought the case kit and hard drives separately, and installed the hard drive myself (which is quite easy to do). These work flawlessly with my iMac. When you look for an external drive, I suggest that you look for a FireWire drive (or combination FireWire/USB 2.0), and be sure that it has the Oxford 911 bridge, as this one is known to work well with Macs.
    I hope this helps.

  • Which  kind of FireWire Camera do you use with Podcast Capture software?

    Hi,
    i have a little question to ask you.
    Could you tell me what kind (product/model) of FW camera you use in order to record video with
    Podcast Capture 2 ?
    we had verified that some FW cameras give problems during acquisition, in the details Podcast Podcature stops automatically the recording giving this error "QTErrorMediaChanged
    The recording has been automatically stopped because the format of the input media changed or the media samples were invalid."
    Thanks

    I've found that PC capture is a bit buggy. For me, sometimes it won't recognize the camera that's attached to the computer. I know that it's not the camera, cause if I quit PC Capture and launch quicktime, then do a video capture, it sees the camera fine. Also, it seems to be 100% reliable.
    So I use it. When you're done recording, you hit stop, then click the pulldown menu ->share->Podcast Capture
    It's an extra step or two, but it's not too complicated for the teachers at my school who have difficulty identifying when their network cables been pulled from the wall when the clue is "My Internet Doesn't Work."
    As to your question, Sony.
    Get a cheapy DV camera. One that takes a tape. If you get one that uses a hard drive or DVD media, I've found that you're asking for trouble even if you can get it to work.
    You can defeat the auto off feature on all Sony Camera's by removing the tape. For whatever reason, if you have a tape in the camera and just leave it on, it'll power off after a bit. I guess it wears down the drum or something. Take the tape out and it'll stay on indefinitely.
    Hope it helps!

  • Which kind of case (brand) i can use for iphone 5s, to take picture inside water ?

    I Would like to take picture inside water, with my iPhone 5s, I see some water proof case on the web, but I don't know which brand apple suggest ?

    Apple do not suggest any. You use them at your own risk. Try Google
    waterproof case for iPhone 5
    Personally for the price of a replacement iPhone if something goes wrong, I would simply buy a waterproof digital camera which are extremely cheap at the moment.

  • Which kind of cache group is suitable for the intensive insertion operation

    Hi Chris,sorry for call you directly. Because you give me many good answers about my many newbile questions these days:)
    You told me that the dynamic cache group is not suitable for the intensive insertion operation
    because each INSERT to a child table has to perform an existence check against Oracle even if load the cache group into RAM manually(Please correct me if wrong).
    Here I have many log tables that they only have a primary key and no foreign references and they are basically used to reflect changes from the related main tables.
    Every insert/update/delete on the main table will insert a log record in the related logging table(No direct foreign references).
    In order to cache these log tables, I have to create a independent cache group for each one, right?
    I do not want load these logs data into RAM because my application do not use them or these logs will waste my RAM clearly.
    so here comes my question.Which kind of cache group should I use to gain the best performance with no loading them into RAM?
    As my understand,the dynamic cache group load data on demand while the regular cache group need load all the data into RAM firstly and it won't load data from oracle anymore?
    Thanks in advance
    SuoNayi

    Let me be more specific. Consider this cache group:
    CREATE DYNAMIC ASYNCHRONOUS WRITETHROUGH CACHE GROUP CG_SWT
    FROM
    TPARENT
    PPK NUMBER(8,0) NOT NULL PRIMARY KEY,
    PCOL1 VARCHAR2(100)
    TCHILD
    CPK NUMBER(6,0) NOT NULL PRIMARY KEY,
    CFK NUMBER(8,0) NOT NULL,
    CCOL1 VARCHAR2(20),
    FOREIGN KEY ( CFK ) REFERENCES TPARENT ( PPK )
    INSERTS into TPARENT will not do any existence check in Oracle. An INSERT INTO TCHILD has to verify that the corresponding parent row exists. If the parent row exists in TimesTen then no check is doen in Oracle. If the parent row does not exist in TimesTen then we have to check if it exists in Oracle and if it does we will load it into TimesTen from Oracle (along with any other child rows) before completing the INSERT in TimesTen. So in the case where the parent always exists already in TimesTen there is no overhead but on the other case there is a lot of overhead.
    If your log table is truly not related to the main table (not in TT and not in Oracle either) then they should go into separate cache groups. If each insert into the log table has a unique key and there is no possibility of duplicates then you do not need to load anything into RAM. You can start with an empty table and just insert into it (since each insert is unique). Of course, if you just keep inserting you will eventually fuill up the memory in TimesTen. So, you need a mechanism to 'purge' no longer needed rows from TimesTen (they will still exist in Oracle of course). There are really two options; investigate TimesTen auotmatic aging (see documentation) - thsi may be adeuate of the insert rate is not too high - or implement a custom purge mechanism using UNLOAD CACHE GROUP (see documentation).

  • How to invoke a jsp page from java which does not use Servlets?

    Hello,
    I am working in Documentum. I am trying to invoke a jsp page from another java page which does not use Servlets.
    I tried doing this by just instantiating the java class related to the jsp page from my present java class.In my java class related to the jsp page, I have defined onInit() and onRender() methods.
    Now, I am trying to call the jsp page from my present java class by just instantiating the java class related to the jsp page. This throws a java.lang.NullPointerException.

  • My table of contents does not use the entry style I select for words in the paragraph that have character styles applied to them in the chapter, so some of the letters are showing up as green, which is fine in the chapter but not in the TOC.

    My table of contents does not use the entry style I select for words in the paragraph that have character styles applied to them in the chapter, so some of the letters, specifically parameters, are showing up green, which is fine in the chapter but not in the TOC. I can manually fix this in the TOC by changing the character style to none after the toc  has been generated, but I don't want to do this.

  • Set a colour to a row in a table view which does not use an iterator

    Hi ,
      I have an application , which displays data using a table view.
    How can i set colour to a row based on the value of one of its coloums.
    The table view does not use an itertator.
    Thanks
    Arun

    you can use the following code in the ONMANIPULATION event to modify the color of the row. but be aware that if SAP changes rendering ot htmlb:tableview it may not work.
    this code sample set the bgcolor of row 2 to blue.
    DATA: httpbody TYPE string .
    CALL METHOD response->if_http_entity~get_cdata
      RECEIVING
        data = httpbody.
    REPLACE ALL OCCURRENCES OF '<tr rr="2"' IN httpbody WITH '<tr rr="2" bgcolor="blue"' IGNORING CASE .
    CALL METHOD response->if_http_entity~set_cdata
      EXPORTING
        data = httpbody.

  • HT4059 Which format does ibooks use?

    Which format does ibooks use?

    if you follow iLife's intended workflow, I don't see any of the huzzle you mention (?)....:
    a) iM is for miniDV.. it copies (=lossless transfer) from miniDV... there's no conversion, as long as you use SD, not HiDef.. and it is NOT intended to import 'foreign' containers as avi...
    b) as long as the iM project is located in the 'Movies' folder, there's no export/conversion/whatever... needed. iDVD detects any content there automatically, with a snap of a click ...
    c) to create a standard videoDVD, there HAS to be a time consuming encoding process, 'cause these standards asks for muxxed mpeg2.. = computation... and, with your help (=maintain system, keep min. 20GB free on system disk, size of your wallet for purchasing überMac etc), this process is fast. plus, using the themes, or using a self-created theme gives your DVDs a professional touch ...
    Plan B)
    get any HDD/DVD standalone corder (I'm using one...); import from camera, the encoding & burning process is on such machines hardware accelerated.. it creates a DVD of a 90min movie in less than 5min .. (import, for sure, in realtime...); plus those devices offers rural editing options.. the DVD menus are ugly..

  • Which form does IDM use?

    For reconciliation, I put in a criteria within the form of the recon admin to check if the status is equal to Termination or not, if so then disable it. If not terminated then put the users in their appropriate organization.
    <Disable>
    <eq>
    <ref>global.status</ref>
    <s>T</s>
    </eq>
    </Disable>
    Everything is fine. All the non-terminated users were in their appropriate organization. The problem is for all the Terminated ones, they were still being created except that they were put outside of the organization.
    I wonder what form does IDM use to create these Terminated users because the form of the recon admin has been disabled already.

    How does weblogic determine which DDL to use when          > creating JMS persistent store?
              The DDL is stored in the weblogic.jar, and a particular DDL is chosen automically based on driver meta-data.
              Version 9.0 (out in beta), provides the option of administratively configuring the DDL file location.
              For unsupported drivers, versions prior to 9.0 require manually running a DDL file to create the JDBC store's backing tables (see JMS doc).
