    <scribe> scribe: bbezaire

roll call

    lofton: looks like we have everyone we expected.

    <tmichel> agenda is fine

    lofton: can we get a WebEx for tomorrow?

    Stuart: I will forward the information

Closure of technical issues

    <lofton>
    [11]http://lists.w3.org/Archives/Public/public-webcgm-wg/2009Apr/001
    9.html

      [11] 
http://lists.w3.org/Archives/Public/public-webcgm-wg/2009Apr/0019.html

    lofton: any items missing?

    list seems complete for now

    1.) editorial issue with 'scale()' method:
    [12]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00051
    .html

      [12] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00051.html

    <tmichel> I have lost you on zakim. I am dialing back.

    lofton: proposing Result: newMatrix = thisMatrix x scale(sx,sy) x
    rotate(angle) x translate(-rx,-ry).

    sorry: Result: newMatrix = thisMatrix x translate(rx,ry) x
    scale(sx,sy) x translate(-rx,-ry).

    lofton: no, I want to remove that. keep it simple.
    ... Result: newMatrix = thisMatrix x scaleMatrix.

    Resolution: simplify it... Result: newMatrix = thisMatrix x
    scaleMatrix.

    2.) QUESTION: 'maplist' or 'mapList'?
    [13]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00066
    .html

      [13] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00066.html

    <lofton> Resolution: convert 'maplist' and 'dashlength' to
    camel-case in the DTD.

    3.) ACI substitution of non-existent font:
    [14]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00037
    .html

      [14] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00037.html

    Don: I think text is clear on that, but a side issue was raised from
    this.

    <lofton> reference:
    [15]http://www.w3.org/Graphics/WebCGM/drafts/current-editor-21/WebCG
    M21-Config.html#ACI-deffont

      [15] 
http://www.w3.org/Graphics/WebCGM/drafts/current-editor-21/WebCGM21-Config.html#ACI-deffont

    Don: can defaultFont be used by itself, without a maplist in the ACI

    Dave: you can have zero maplist in the file

    Don: ok, good.

    <lofton> Resolution: no changes needed.

    we will get back getObjectExtent a bit later, skip it for now

    5.) ACI DTD and conformance:
    [16]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00100
    .html (Proposed: Dave's new wording.)

      [16] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00100.html

    Rob: I think the biggest thing missing right now is that it doesn't
    say it has to be a valid document, but only a well-formed document.

    <lofton>
    [17]http://lists.w3.org/Archives/Public/public-webcgm-wg/2009Apr/001
    8.html

      [17] 
http://lists.w3.org/Archives/Public/public-webcgm-wg/2009Apr/0018.html

    <lofton> Resolution: fix Ch.9 conformance bits per Dave's proposal.

    6.) upgrade XML 1.0 references to 5th Edition:
    [18]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00104
    .html

      [18] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00104.html

    Rob: we reference more than one edition for XML 1.0

    lofton: would it change any conformance criteria for WebCGM 2.1?
    ... I've also seen a thread on erratum processing against the 5th
    edition

    <scribe> ACTION: Rob to investigate if XML 1.0 5th edition has
    implication on WebCGM. [recorded in
    [19]http://www.w3.org/2009/04/27-webcgm-minutes.html#action01]

      [19] http://www.w3.org/2009/04/27-webcgm-minutes.html#action01

    <trackbot> Sorry, couldn't find user - Rob

    4.) getObjectExtent and text (thread splits):

    [20]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00077
    .html

      [20] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00077.html

    [21]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00078
    .html

      [21] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00078.html

    [22]http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00116
    .html

      [22] 
http://lists.oasis-open.org/archives/cgmo-webcgm/200904/msg00116.html

    <Stuart> Sorry, I need to run. I will be back as soon as I can.

    <dave> me too, gotta run

    lofton: I think someone should take Forrest's information and draw a
    picture of it.
    ... and identify where the y-min and y-max should be

    <scribe> ACTION: Forrest to draw a picture of the y-min and y-max
    values of a few characters [recorded in
    [23]http://www.w3.org/2009/04/27-webcgm-minutes.html#action02]

      [23] http://www.w3.org/2009/04/27-webcgm-minutes.html#action02

    <trackbot> Sorry, couldn't find user - Forrest

Review of TC's Test Suite progress

    <tmichel> thanks i can access the FTP

    <tmichel> ftp://ftp.cgmlarson.com/

    <lofton> ftp://ftp.cgmlarson.com/test-matrix.htm

    <tmichel> and now ftp://ftp.cgmlarson.com/test-matrix.htm works also

    lofton: I think we should publish a snapshot of the test suite.

    Don: we should sync it with the next draft

    lofton: I think that's a good idea.

    tmichel: do we plan to advertise the test suite?

    lofton: no, not for the 2nd last call

    tmichel: ok, only for CR.

    <lofton> Resolution: the WG recommends that the TC should publish a
    snapshot of the Test Suite at the same time as the anticipated 2nd
    LCWD is published.

    issue on transformAPS test

    Ulrich: we agree with Forrest's findings
    ... we are looking into this.

    <lofton> (transformAnimation may be affected as well.)

    <lofton> next: setGetFillOffset issue

    Forrest: I think the CGM file I submitted should be modified

    Ulrich: what is the implication of setGetFillOffset on the picture
    level?

    lofton: do we have any other style properties that apply only to APS
    and not the picture?

    Ulrich: the test is fine if we want to apply this at the picture
    level

    lofton: should we test the set and get at the picture level for one
    or more SP?

    Don: yes, I think it would make the test suite more complete

    lofton: I think we should use one of the simpler SPs to test the
    picture level.

    <scribe> ACTION: Forrest to change fill-offset test to target APS
    level [recorded in
    [24]http://www.w3.org/2009/04/27-webcgm-minutes.html#action03]

      [24] http://www.w3.org/2009/04/27-webcgm-minutes.html#action03

    <trackbot> Sorry, couldn't find user - Forrest

    <scribe> ACTION: Forrest to create a new test targeting a SP at the
    Picture level [recorded in
    [25]http://www.w3.org/2009/04/27-webcgm-minutes.html#action04]

      [25] http://www.w3.org/2009/04/27-webcgm-minutes.html#action04

    <trackbot> Sorry, couldn't find user - Forrest

    <lofton> issue: aciFileSearch

    <trackbot> Created ISSUE-18 - AciFileSearch ; please complete
    additional details at
    [26]http://www.w3.org/Graphics/WebCGM/WG/track/issues/18/edit .

      [26] http://www.w3.org/Graphics/WebCGM/WG/track/issues/18/edit

    <lofton> next: aciFileSearch problem

    Don: we couldn't find a good way to test aciFileSearch, we couldn't
    see a way to do one with real value
    ... we should replace the example in 9.2.3 from /WebCGM to
    /WebCGM.aci

    <lofton> I will fix the example in 9.2.3 so that it is a complete
    path to the ACI *file*, not just a directory.

    <lofton> We will call this to Stuart and Dave's attention for any
    further feedback (and put on Tues agenda).

    <lofton> Resolution: aciFileSearch test should be removed from the
    test suite.

    next: getObjectExtent

    talking about Figure 11 in CGM:1999

    <stuart> I am dialing in

    lofton: lets talk about getObjectExtent after Forrest has completed
    his action item

Assignments for Tuesday

    all items: graph the font metric marks, look at XML 1.0 5e upgrade,
    transformAPS test, setGetFillOffset test have an action item

Review of proposed progression

    lofton: I will contact implementers to see if mid-July CR/test-fest
    F2F makes sense

    talking about last call publication

    tmichel: it is common practice to request feedback only on the
    latest changes.

    <tmichel> let me redial ...

    Thierry and Lofton will look into diffs of past draft documents.

    adjourn
