In SVG equally spaced characters including spaces

SVG doesn�t seem to honor equal spacing in equally spaced
fonts like Courier. What is the key to making text equally
spaced including space characters?
I need to convert an old program output that needs an equally
spaced font in text including embedded and leading
space characters (leading spaces might be more difficult).
How do I do this when SVG seems to do its own thing with
spaces even on monospaced fonts?
I must be unaware of some attribute.

I believe I have it resolved.
The following in the .svg file with the "xml:" inserted works:
<text x="3.0" y="211.0">
<tspan xml:space="preserve"> here is what I want </tspan>
</text>
The following WITHOUT the "xml:" inserted does not preserve spaces:
<text x="3.0" y="211.0">
<tspan space="preserve"> here is what I want </tspan>
</text>
The (first) correct(believably) version is produced in Java-JDOM by:
tspanNode.setAttribute("space","preserve",Namespace.XML_NAMESPACE);
and the latter incorrect version is produced in Java-JDOM by:
tspanNode.setAttribute("space","preserve");
where tspanNode is a JDOM Element producing <tspan></tspan>.

  • How do I find the number of characters including spaces in Pages '13?

    Hi,
    I need the number of characters including spaces on the new pages for an online document I have to fill in. I've found the character count excluding spaces but this is of no use to me.

  • How to read a whole file as a set of characters (including spaces)

    Hi,
    I'mt trying to read a file, and i want to save each character in the file including the space character. Is there a new line char as well?
    I'm using this at the moment because buffer reader loses my trailing spaces, but it's only taking the first word of my file:
    Scanner scan = new Scanner(System.in);
                System.out.print("Enter a filename: ");
                String fileToRead = scan.nextLine();
                Scanner sc = new Scanner(new File(fileToRead));
                String file = sc.next(); //this only takes the first wordIs there any way of saving this whole file as a string so that it also remembers spaces and new lines?

    That isn't my experience with BufferedReader. If you use the readLine method it will read lines, throwing away the crlf, but if you use the read(buffer,ofs,len) methods it happily reads everything and puts it in a character array. You can then convert that to a string using the new String(buffer, ofs, len) method.
    Here's a simple test case:
    import java.io.*;
    public class ReadTest {
         public static void main(String [] args) {
              for (String arg : args) {
                   char [] buffer = new char[256]; ;
                   try {
                        BufferedReader reader = new BufferedReader(new FileReader(arg));
                        int len = 0;
                        System.out.println("reading from file="+arg);
                        while (true) {
                             len = reader.read(buffer,0, 256);
                             if (len == -1) {
                                  break;
                             System.out.println("read "+len+" chars="+new String(buffer,0,len)+"||");
                             System.out.println("");
                        reader.close();
                   } catch (IOException e) {
                        System.out.println(e.getMessage());
    }

  • How can I calculate the characters with spaces in a document on pages

    I'm currently using pages to write my personal statement up on, although i need to keep my characters including spaces under 4000 characters and also have no more than 47 lines. I've found how to do a word count and find how many charcaters I've used, but i can't see anywhere the information that I actually need to find! Someone please help, thankyou

    How can you calculate the number of lines if you don't know how many characters there are to a line?
    This is 2013. We are using word processors with real fonts, not terminals or teletypers or typewriters.
    If you must have 47 lines then shrink the point size of the font until it fits.

  • How to distribute equal spacing with anchor points?

    I am working in Lesson 5 of Adobe Illustrator CS5 Classroom in a Book, and am having a problem selecting the 2 anchor points to distribute equal space based on the bottom center anchor point of the violin.  The note said to reference chapter 2, which I have already been through, but even after reading the Illustrator Help dialog on pg 75, I am still at a loss.  Can anyone explain how to distribute this equal spacing of 2 anchors relative to one anchor point?

    csnpreggers,
    If anyone has any further advice or comment, I'd still love to hear from all parties.
    Especially when working with a finished symmetrical shape, such as a violin, which may have been created using mirroring, in other words elaborating on a shape, possibly with something unforeseen in the first round, and especially when it is inconvenient to cut paths to work with one half, you may use the instructions in small print using invisible ink at the bottom of item 3 in lesson 5:
    2 tips, using the Line Tool and Smart Guides:
    To make sure the left Anchor Point has the same same distance from the bottom Anchor Point, first ShiftDrag horizontally with the Line Segment Tool from the right Anchor Point to cross the path, then select the violin path and click it with the Add Anchor Point Tool where Smart Guides say intersect.
    Or to place both Anchor Points at the same time instead, first create a sufficiently long horizontal path with the Line Segment Tool below the violin path, then ShiftDrag it upwards to cross the violin path at the desired distances, then select the violin path and click it with the Add Anchor Point Tool where Smart Guides say intersect, both right and left.

  • How to include spaces in javaplugin.jre.params

    G'day,
    I;m working with the Java Plug-In v1.3.1 with Windows 2000 and would like to define a property using the javaplugin.jre.params, namely
    javaplugin.jre.params=-Djava.ext.dirs\=D\:/Documents and Settings/cpudney/lib/ext
    so I can define my own standard extensions directory (actually it's a bit more complicated but the crux of the problem is given here). This is done in D:\Documents and Settings\cpudney\.java\properties131 (or via the Java Plug-in console).
    The problem is that the path name includes spaces, so when the plug-in runs java.ext.dirs=D:/Documents
    I've tried escaping the spaces with backslashes, enclosing in quotes, using %20 and \u0020 but nothing works.
    The obvious workaround is to use the DOS 8.3 name (D:/DOCUME~1/cpudney/lib/ext) but I want to avoid having to do this.
    Any help would be appreciated.
    Thanks,
    Chris.

    Hey Chris,
    The bad news, this is a known bug. See http://developer.java.sun.com/developer/bugParade/bugs/4795045.html
    The good news, this has been fixed in Tiger/1.5
    Although, if you are still using 1.3x, I'll bet you can't easily migrate to 1.5 when it is released.
    Is the DOS 8.1 naming that bad to use in the meantime? The more I toyed with possible workarounds, the more enticing the 8.1 naming seemed.

  • Converting control characters to spaces in a Unicode program?

    I want to take an ASCII character string and convert any
    ASCII Control Characters to Spaces.
    In a non-Unicode program, I define the following hex constant:
    CONSTANTS: c_control_to_space(64) TYPE x VALUE
      '00200120022003200420052006200720082009200A200B200C200D200E200F20' &
      '10201120122013201420012016201720182019201A201B201C201D201E201F20'.
    I then execute the following TRANSLATE statement:
          TRANSLATE w_transcript USING c_control_to_space.
    What would be the "approved" method of accomplishing the same effect
    in a Unicode program?

    Neil,
    First, thank you for pointing out my typo. You are correct that the "0120" in the second line of the literal was intended to be "1520".
    Second, thank you for your suggestion. Based on your idea, I tried something similar, but not exactly what you suggested. In particular, since I can't figure out how to construct the constant that I want, I used your idea to construct it as  a variable, as follows:
      DATA number TYPE i.
      DATA offset TYPE i.
      DATA hex(4) TYPE x.
      FIELD-SYMBOLS <char> TYPE c.
      ASSIGN hex TO <char> CASTING TYPE c.
      DATA w_control_to_space(64) TYPE c.
      DO 32 TIMES.
        hex = sy-index - 1.
        offset = 2 * ( sy-index - 1 ).
        number = STRLEN( <char> ).
        IF number GT 1.
          SUBTRACT 1 FROM number.
          SHIFT <char> LEFT BY number PLACES.
        ENDIF.
        w_control_to_space+offset(1) = <char>.
      ENDDO.
    After having constructed "w_control_to_space", I can now use the TRANSLATE statement:
      TRANSLATE w_transcript USING w_control_to_space.
    This code passes the Unicode syntax checks and works correctly on a non-Unicode system. I don't have access to a Unicode system on which to run it. I'd appreciate any feedback on this approach - especially if someone can actually test it on a Unicode system.

  • Special Characters and spaces in Tablenames and Column Names are allowed ?

    Hi
    I have created two tables in Oracle10g
    as follows
    SQL> create table test(columna number,columnb varchar2(20),primary key(columna));
    Table created.
    SQL> insert into test values(1,'test');
    1 row created.
    SQL> commit;
    COMMIT är utfört.
    SQL> create table "test quote"("#" number,abc number,primary key("#"));
    Table created.
    SQL> insert into "test quote" values(1,2);
    1 row created.
    SQL> commit;
    COMMIT är utfört.
    SQL> select * from "test quote";
    # ABC
    1 2
    SQL> select * from test;
    COLUMNA COLUMNB
    1 test
    Now I want to cache the tables and their data into TimesTen
    The cache group for table test which is not having any spaces and special characters in table name and column names is created perfectly.
    But when I create the cache group for table "test quote" which is having special characters and spaces it gives error :
    Command>create readonly cache group w2 from testuser.test(columna number,columnb varchar2(20),primary key(columna));
    Command>select * from test;
    <1,test>
    1 row found.
    Command>create readonly cache group w3 from testuser."test quote"("#" number,abc number,primary key("#"));
    5140: Could not find TESTUSER.TEST QUOTE in Oracle. May not have privileges.
    Command Failed.
    Now there is contradiction that why cache group for table test is created successfully and why it is not being created for table "test quote".
    What I think is if special characters and spaces in column names and table names are possible in Oracle then it sould be possible in TimesTen.
    Any possible solution.
    Looking forward for your reply.
    Please help I am stuck badly.

  • Align palette: equal spacing possible between stroke edges not just fill edges.

    right now with align palette, you can choose an equal spacing between edges of fills, as the bottom row shows, the top row shows alignment and spacing is only possible between the paths of strokes, not their outside edge. So I`m hoping we can also apply equal spacing between the outside edges of strokes, without having to convert them to fills for CS6

    I understand. You're right, but now it is not difficult to switch on the SmartGuides unnecessarily interfere and instead of helping.
    Maybe the idea would be smart guides to be involved only for the selected objects — kind "smart aligns"?
    In Illustrator, I miss these smart fix intervening only in specific situations. Introduced in Illustrator a lot of very good features but their use is still in the spirit of the 90s usebility. I know that it is easy to criticize but I just work on many different programs and when I toggle to Illustartors immediately feel a different world.

  • Sampling/T​riggering externally with DSA cards with even sample spacing in frequency space

    Hi there,
    Is it possible for the NI DSA cards to trigger on a signal to record at a desired time, at an un-even spacing in the time domain. For my application I need to have the samples evenly spaced in frequency space.
    I would set the first channel for acquisition from the source. Would use the external trigger port, or the second channel for the trigger signal? 
    This is for a optical coherence tomography system.
    Thanks! 

    Hi Anthony,
    You may have to excuse some of what I say since I am still a bit uncertain of what you need to accomplish due to my lack of understand of OCT. If you wanted to start your acquisitino at a given time by using an external trigger, most cards have a trigger input which will allow you to do so. However, using an external clock will be much more difficult. While it will be difficult to use an external clock signal with a DSA device, resampling may be a better option. Here is an article which shows some of the resampling functions which, by my understanding, may accomplish what you need to do. Let me know if this puts us in a better direction.

  • Equal spacing between the images of uniformed height but variable widths with AS3?

    I have to figure out how to insert images with variable width with equal spacing intervals.
    Here is where I got so far:
    function buildScroller(imageList:XMLList):void{
              trace("build Scroller");
              for (var item:uint = 0; item<imageList.length();item++) {
                        var thisOne:MovieClip = new MovieClip();
      var currentX = 90;
                        var spaceBetween = 20;
      var currentImageWidth = Number(imageList[item].attribute("width"));
    thisOne.x = currentX;
    thisOne.x = (currentImageWidth+spaceBetween)*item;
    I can see that my images are being spread out on the page and if I change the number in var spaceBetween it affects the spacing. However the spacing is not uniformed. I can not figure why. Perhaps because I can not properly retrieve the image widths from the xml file. I assigned a width in xml file in the following manner:
    <images>
    <image src="appThmb_imgs/A-illuminatorUpLit_xsm.jpg" title="UpDownGlowingVase" url="http://www.888acolyte.com" width="132"/>
    <image src="appThmb_imgs/ATI-1-bgpA_xsm.jpg" title="CoolingReflections" url="http://www.888acolyte.com" width="117"/>
    <image src="appThmb_imgs/ATI-2-zenC_xsm.jpg" title="OrchidsUnderGlass" url="http://www.888acolyte.com" width="263"/>
    <image src="appThmb_imgs/SilverBloom_RGB_xsm.jpg" title="SilverBloom" url="http://www.888acolyte.com" width="148"/>
    </images>
    they correspond to actual image width. I do however want them to be scaled at 50% of their actual width.
    Any ideas if I am missing a line of code or don't call out images properly?

    Thank You for your reply.
    I tried to implement it but images are still jambled together.
    Perhaps it has something to do with the fact that I specify the actual width of the image in the XML file but then define it as a scaled value in the code later on (11th line at the bottom of the code):
        mc.height = 110;
    This height definition will just give the width proportional to the height. Does it mean that I can not specify the height as it is?
    Also can be there a mistake in the XML file? I just assigned the width number as it is in pixels for each image. Here is an example:
    <images>
    <image src="appThmb_imgs/RosesGallasGalore_RGB_xsm.jpg" title="RosesGallasGalore" url="http://www.888acolyte.com" width="131"/>
    <image src="appThmb_imgs/SangriaBling_RGB_xsm.jpg" title="SangriaBling" url="http://www.888acolyte.com" width="233"/>
    <image src="appThmb_imgs/SilverBloom_RGB_xsm.jpg" title="SilverBloom" url="http://www.888acolyte.com" width="148"/>

  • How to specify sourcepath including spaces?

    Hi, I am new here.
    I trled to generale a javadoc from my package under D:\Apache Group\Tomcat 4.1\webapps\<myapp>\WEB-INF\classes\<my package> some times (The tree is argument of -sourcepath). However an error occurred.
    javadoc (command) says...
    javadoc: Illegal package name: "Group\Tomcat"
    javadoc: Illegal package name: "4.1\webapps\<myapp>\WEB-INF\classes\<my package>"
    the command makes it separated.
    Can't specify sourcepath including spaces? or Is there substitute way to specify? I can move the package to another directory not including spaces though, but it is inefficient for development...
    I will appreciate helps.

    Try enclosing the argument for the sourcepath option in quotation marks:-sourcepath "D:\Apache Group\Tomcat 4.1\..."

  • Limit rows per page, include spacer and format last row on page break

    Hello,
    I am new to BI and would like some help with an issue I don't seem to be able to resolve?
    I have a table that uses two xml group elements (2nd nested inside first) to produce my detail lines.
    Example:-
    First for-each loop runs over shipto details and within this another for-each loop runs over items related to that shipto, all of which results in multiple detail lines.
    I need to limit the number of rows per page and should the data roll over to the next page I need to place a horizontal closing border on the first page's table (only using column borders).
    Also when the data does not fill the page I need to add spacer rows to the page limit?
    I have tried using examples found in these forums, position(), counters etc… but due to having the second detail loop I’m unable to get these working or I’m doing something wrong?
    Your help would be greatly appreciated.

    Hi BIPuser, thanks for the links.
    I have tried some of the examples which I can get working with a single level of detail lines. However when I add the second level of detail lines the position() function seems to fail as my rowlimit appears to be ignored.
    I am also unable to get the $lpp example working because the outer detail loop may only have one xml element and therefore BI assumes only one line is to be printed when in fact the inner xml element detail loop may have further multiple lines. I need to effectively count the outer & inner loops as one to determine the number of lines being processed.
    Example of xml - My table for detail lines needs to include both ShipTo & item number lines grouped as shown, thereby counting & outputting 7 lines in this instance.
