How to create CS5 arrow

[kokutenho]

Please teach me the creation method of the arrow added newly by CS5.

It is two that I do not understand.

How should AIPatternHandle of an arrow be acquired? I found AIBeautifulStrokesSuite::SetArrowheadOptions. However, there is no telling where beginSymbol and endSymbol should be acquired from.

Another is the creation method with an arrow of PathArt. I tried AIBeautifulStrokesSuite::GenerateArt. However, the divided arrow has been created in this API.

Well, the first part is easy to explain: beginSymbol & endSymbol are symbols You can acquire them using the AISymbolSuite (AISymbol.h), either by name or by index (from the master symbol list).

The second part I don't fully understand. Can you elaborate? I can't what you're trying to create exactly.

Thank you for your reply.

I misunderstood the 2nd problem.

A setup of the arrow was completed by the following methods.

    AIDictionaryRef paramDict = NULL;

    AIStrokeStyle strokeStyle;

    AIBoolean hasBrush;

    AIReal scaleFactor;

    AIBoolean canAccept;

    err = sAIBeautifulStrokes->GetArtStrokeParams(hArt, paramDict, &strokeStyle, &hasBrush, &scaleFactor, &canAccept);

          AIPatternHandle beginSymbol= NULL, endSymbol= NULL;

    AIReal beginScale = 1.0, endScale = 1.0;

    ArrowTipAlignment alignment;

    AIBoolean mixedBeginArrows = FALSE, mixedEndArrows = FALSE;

    err = sAIBeautifulStrokes->GetArrowheadOptions(

        paramDict, &beginSymbol, &endSymbol,

                    &beginScale, &endScale, &alignment,

        &mixedBeginArrows, &mixedEndArrows);

    if (beginSymbol && !endSymbol) {

        err = sAIBeautifulStrokes->SetArrowheadOptions(

            paramDict, &beginSymbol, &beginSymbol,

                        beginScale, beginScale, alignment);

    } else if (!beginSymbol && endSymbol) {

        err = sAIBeautifulStrokes->SetArrowheadOptions(

            paramDict, &endSymbol, &endSymbol,

                        endScale, endScale, alignment);

    }

    err = sAIDictionary->Release(paramDict);

However, the 1st problem is not solved.

I tried the following ways.

    ai::int32 count;

    ASBoolean includeUnlisted;

    ai::UnicodeString name;

    AIPatternHandle symbolPattern;

    //includeUnlisted = true

    includeUnlisted = true;

    err = sAISymbol->CountSymbolPatterns(&count, includeUnlisted);

    TRACE(L"includeUnlisted = true:%d\n", count);

    for (ai::int32 i = 0; i < count; ++i) {

        AIPatternHandle symbolPattern;

        err = sAISymbol->GetNthSymbolPattern(i, &symbolPattern, includeUnlisted);

        err = sAIPattern->GetPatternName(symbolPattern, name);

        TRACE("%s\n", name.as_Platform().c_str());

    }

    //includeUnlisted = false

    includeUnlisted = false;

    err = sAISymbol->CountSymbolPatterns(&count, includeUnlisted);

    TRACE(L"includeUnlisted = false:%d\n", count);

    for (ai::int32 i = 0; i < count; ++i) {

              err = sAISymbol->GetNthSymbolPattern(i, &symbolPattern, includeUnlisted);

        err = sAIPattern->GetPatternName(symbolPattern, name);

        TRACE("%s\n", name.as_Platform().c_str());

    }

    //document

    AIDocumentHandle document = NULL;

    sAIDocument->GetDocument(&document);

    err = sAISymbol->CountSymbolPatternsFromDocument(&count, document);

    TRACE(L"document:%d\n", count);

    for (ai::int32 i = 0; i < count; ++i) {

        err = sAISymbol->GetNthSymbolPatternFromDocument(i, &symbolPattern, document);

        err = sAIPattern->GetPatternName(symbolPattern, name);

        TRACE("%s\n", name.as_Platform().c_str());

    }

The value of "count" is always 6.

And the six are in a symbol palette.

How can I get a symbol from the master symbol list?

[A. Patterson]

I'm not sure why the problem is, so bear with me. There are six symbols -- if there are six symbols in the master symbol list, that's correct. You look like you have the correct code to retrieve a handle, so you're good.

Actually, maybe I do get it. Are you asking where the arrowhead symbols are? Because they're not actually in the document -- that takes a bit of effort to get (something I only recently learned out to do) so if that's the problem I can help there.
