The analysis of GPX Format

Hello. If someone managed to analyze the gpx XML data. The XML looks like this:

< gpx version = "1.1" creator = "Explorer of Trail Mobile" >
< trk >
< trkseg >
< trkpt lat = lon "51.539498" = "-0.488798" >
< model > 31.5 < / ele >
< time > 2007-11-30T 13: 07:03Z < / time >
< / trkpt >
< / trk >
< / gpx >

so far, my analysis function looks like this:

public static void parseGPS(journey:FileStream):ArrayCollection {}
var gpe:GPSEntry = new GPSEntry();
var ac:ArrayCollection = new ArrayCollection();
var str:String = journey.readUTFBytes (journey.bytesAvailable);
var XML = XML (str);
var trkptLength:Number = xml.childNodes [0] Sublst.ChildNodes(1).ChildNodes(0) [0].childNodes.length;
var gpsTagCnt:Number = 3;
var trackpointArr:Array = new Array (gpsTagCnt);

for (var i: uint = 0; i < trkptLength; i ++) {}
trackpointArr = new Array (gpsTagCnt);
var now_trkpt:XML = xml.childNodes [0] Sublst.ChildNodes(1).ChildNodes(0) [0] Sublst.ChildNodes(1).ChildNodes(0)
;
trackpointArr [0] = now_trkpt.attributes.lat;
trackpointArr
[1] = now_trkpt.attributes.lon;
trackpointArr [2] = now_trkpt.childNodes [0] .firstChild;
trackpointArr
[3] = now_trkpt.childNodes [1] .firstChild;

GPE. ELE = trackpointArr [2];
GPE.lat trackpointArr =
[0];
GPE.long = trackpointArr [1];
GPE. Time = trackpointArr
[3];

ac.addItem (gpe);
}

return ac;

}


The file stream is passed from the mxml application. It returns a collection of table to display in a datagrid

I managed to do it. Here is the answer.

public static void parseGPS(journey:FileStream):ArrayCollection {}

var ac:ArrayCollection = new ArrayCollection();
var str:String = journey.readUTFBytes (journey.bytesAvailable);
var XML = XML (str);
xml.ignoreWhite = true;
var node: XMLList = xml.children ();
var trkptLength:Number = nodes.children () [0] .children () .length ();

for (var i: Number = 0; i
var gpe:GPSEntry = new GPSEntry();
GPE.lat = nodes.children () [0] .children () .@lat;
GPE.long = nodes.children () [0] .children ()
.@lon;
GPE. ELE = nodes.children () [0] ( ) .children. children() [0];
GPE. Time = nodes.children () [0] .children ()
. children() [1];

ac.addItem (gpe);
}

return ac;

}

  • Save the analysis in PDF format

    I want to scan and save a document in pdf format. However, the Windows settings, Scan & Fax appear only to allow me to save in files such as JPEG picture, etc. I can't find a way to change the settings. Help please!

    As Malke said... also, if your scanning software does not support scanning to PDF you may be interested in Scan to PDF software ofhttp://www.softi.co.uk/ (I recently evaluated this software for use of clients).   It works well but costs $29.99, there is a free 30-day trial.  I have not found a free or shareware equivalent that works reliably.

    Hello.  I'm currently editing digital music pdf using Adobe Acrobat DC on a Lenovo tablet with Windows 7 operating system.  Adobe Acrobat rejects the analysis as unchangeable.  I export the scanned pdf to MS Word and re-export to AADC in pdf format.  This can be cropped, but the edit function does not allow the movement of the measures (or 'skin measures text') within a team.  I am producing pages with 3 litters per page and 3 measures by staff who can be sufficiently enlarged to a blind musician.  My failure to change the measures so far means there is too much information by page and the page can be expanded properly. Advice please.  Thank you.  Charles.

    This is well beyond what Acrobat is intended - not just a little far, but a lot. PDF is therefore completely inappropriate for this.

    I couldn't find the box uncheck the box to 'Save as individual file' to the Mac.

    My reccomendation is to use the Image Capture in your Applications folder.  Choose your scanner to the left, then click on "Show details" on the bottom.

    Choose the PDF format, then check the box for "combine several pages into single file" (or similar words).

  • The analysis of the non-numeric characters in a string

    Hello

    I am communicating a robot to LabVIEW (2013) via TCP/IP and sockets. The robot is the server, and LV is the customer.

    I start with the target data in this format (in a string):

    "[0 ~ 100 ~ 0] ~ [0.96593 ~-0.25882 ~ 0 ~ 0] ~ [1 ~ 0 ~ 0 ~ 0] ~ [150 ~ 50]."

    [X, Y, Z], [Q1, Q2, Q3, Q4], [C1, C4, C6, Cx], [TCPVel, OrientVel] except replacement ',' (comma) with a ' ~ ' (tilde) because I load the target data in a spreadsheet which is a comma-delimited file.

    In LV, I take this string, the analysis of the chain and split individual items. I then pulled the singular elements as unique, 32-bit of real numbers. I take each one and convert them individually to a string, concatenate them and send them to the robot. The robot decompresses these raw bytes individually and converts them to a target of robot (position in space).

    I train (BT) check if the user has sent a bad character (non-digital) in the target data. Example of this is:

    [- 50 ~-150 ~ 0] ~ [0.96593 ~-0 ] [B2has5D882 ~ 0 ~ 0] ~ [1 ~-1 ~ 0 ~ 0] ~ [150 ~ 50]

    Now in BT, when I'm scanning the chain, these bad character becomes the entire element to zero and everything else then to zero as well. See attachment for example screen similar.

    My question is, my VI, I can analyze all non-numeric characters (that are inside the parentheses and characters that are NOT a ' ~ ' (tilde))? In this way, I can always get this item numbers and do not have this element or other items turn to zero?

    Thanks in advance for any help!

  • Anyone who works with the CAF (Caltech intermediate Format) files in LabVIEW?

    Hey everybody,

    Anyone who works with the CAF (Caltech intermediate Format) files? These are files that are generated by IC layout programs, such as TannerEDA L-Edit, that define the layers and arrangement of the masks used in VLSI (Photolithography) of processing semiconductor device.

    I would like to analyse these CIF files to generate a map of wafer of devices for use in the-plate test. Currently, a plan of shooting is made and then I manually switch and define coordinates of line and column for the edge of a plate and various places of drop-in. I would like to automate this process, and I don't know if it is possible by playback of these files from the CAF. However, I don't really know how to read them, and I can get as much information from the Wikipedia page and the original article.

    So I ask: anyone has an easier set of screws that make reading CIF file? Or someone working with them can help me with my problem? I can describe it in much better detail once someone comes...

    Here is one of my notebooks CIF of Mathematica (remove the .txt extension obviously).  I used it to create a new CIF file with four instances of the object in a file.

    You can load a file with the following text:

    symName = loadCIF;

    You can see the layers:

    CIFlayers [symName]

    You can view layers:

    Show [{viewCIFlayer [symName, #, color of layer]}]

    (if you wish, add multiple layers to the list)

    If you have a file of type CIF I can also test to see that it recognizes the objects you use, I am generally to polygons and boxes.

  • The analysis of lists in PL/JSON

    I'm working on parsing a json string that is stored in a CLOB table in oracle 11g. This process belongs to a long analysis of routine which analyzes the data and stores the values in another table, and I just noticed that part of my data is not out. The json analysis and valid with JSONLint. So I simplified the analysis to try to find out where I'm wrong.

    So my json out of my table looks like this.

    {

    'JSON_data': {}

    "plant_id": "3006."

    "transmit_time": "2015-12-18 11:57:45."

    'messages': [{}

    'work_msg': {}

    "msg_time": "2015-06-23 04:54:17", ".

    "trigger_type':"interval. "

    'vert_correction': 358,3,

    'ch_latitude': 37.916302,

    'ch_longitude':-87.487365,

    'ch_heading': 212,3,.

    'ch_cable_port': 1029.79,

    'ch_cable_stbd': 348.63,.

    'ch_depth':-27.03,

    'slurry_velocity': 25.71,.

    'slurry_density': 1.02,.

    'ch_rpm': 205.49,.

    'ch_psi': 540.89.

    'prod_instantaneous': 0,

    'prod_cumulative': 1216.100000,

    'outfall_latitude': 37.915967,

    'outfall_longitude':-87.484369,

    'outfall_heading': 120,7,.

    "pump_entries": [{}

    'pump_name': 'main ',.

    'empty': 12.73.

    'outlet_psi': 22,88

    }],

    "spud_entries": [{}

    'position': 6

    }]

    },

    'pipe_length_event': {}

    "msg_time": "2015-06-23 04:54:17", ".

    "length_floating": 970

    }

    }]

    }

    }

    My analysis is properly find and do his thing with the data "work_msg". It's the data 'pipe_length_event' that I don't get to. Here is my pl/sql procedure.

    DECLARE

    vCONTENT CLOB.
    v_parent_json json;
    v_json_message_list json_list;
    v_json_message_list_value json_value;
    v_parent_json_value json_value;

    BEGIN

    SELECT CONTENT IN SJM_TEMP4 vCONTENT;

    v_parent_json: = json (vCONTENT);
    v_parent_json: = json (v_parent_json.get (1));

    v_json_message_list: = json_list (v_parent_json.get ('messages'));

    DBMS_OUTPUT. Put_line (v_json_message_list. (Count);

    for message_loop_counter in 1... loop v_json_message_list. Count
    v_parent_json_value: = json (v_json_message_list.get (message_loop_counter)) .get (1);

    If v_parent_json_value.mapname = "work_msg" then
    DBMS_OUTPUT. Put_line ('FOUND: work_msg');
    on the other
    DBMS_OUTPUT. Put_line (v_parent_json_value.mapname);
    end if;

    END LOOP;

    END;

    My dbms_output first gives me a sublist from 1 account. 2. not so my analysis does not yet recognize the 'pipe_length_event' as a sublist of "messages".

    How can I get data 'pipe_length_event' by using this procedure? I am almost sure that it worked in the past, so my first thought is that json is formatted differently. Is the json in the wrong format?

    Thanks in advance.

    They moved their forums to StackOverflow.  I had posted my question there before here.  In any case, I found my own answer.  JSON is not properly formatted.  The 'work_msg' was not closed correctly, and "pipe_length_event" has not been opened in a new list.  So once I had that all squared away he analysed very well.

    For reference, the correct formatting is below.

    {

    'JSON_data': {}

    "plant_id": "3006."

    "transmit_time": "2015-12-18 11:57:45."

  • Download the video in MPG format to iCloud photo library

    Is it possible to download a video file, MPG to a Mac to iCloud photo library?

    I stopped using iCloud photo library on the Mac due to low disk space, however I always use iCloud photo library on other devices and would like to have the video available here. I tried to use the web interface to iCloud by using Safari, but I get a message that the format is not supported

    I guess I could convert the file in another format, however, I do not want 3rd party applications on my Mac, and I worry about compromising video quality. Is the other way to do this? Could using Photos (1.5) on the Mac and the activation of my photo stream get the video to appear in the photo library of iCloud?

    As we told you MPG is not a format alternative for ICPL

    Types of files that you can use with iCloud photo library

    Your photos and videos are stored in iCloud, exactly as you took them. All your images are in their original format in full resolution, JPEG, RAW, PNG, GIF, TIFF, and MP4, as well as special formats capture you with your iPhone, like slo - mo, Time lapse video 4K and Live Photos.

    If your recovery CD contains the Vista operating system then the installation procedure is very easy.
    You need to boot from the Toshiba Recovery CD and follow the instructions on the screen. Installation would format the drive HARD integer (clear partitions too) and would install Vista, driver, tools, tools and software on the laptop.
