Re: [Guidolib-devel] iOS Guido Lib

[Michael C. <win...@gm...>]

Hello again.

I compiled guido for iOS. Note that, in the resulting Xcode Project, the
"arm64" must also be included, otherwise the library is not usable in newer
projects.

Now I 'm trying to draw a sample score to a CGContextRef, using the
following code. All the functions succeed, but nothing is shown. I'm not
sure if it loads the guido2 font, but in any case the text is not displayed
as well.

I 'm calling this from drawRect: from an UIScrollView:

void g(CGContextRef d1,int wi,int he)
{
    GSystemOSX sys(d1, d1);
    GDeviceOSX dev(wi,he,&sys);
    GuidoInitDesc gd = { &dev, 0, "guido2", "Optima" }; // Is this correct
? I 've included guido2.ttf in the project and in plist
    GuidoOnDrawDesc desc;
    GuidoInit (&gd);
    ARHandler arh = 0;
    const char* a1 = "{ [   \\meter<\"4/4\"> \\tempo<\"This is a sample
line\"> c ] }";
    GuidoParseString(a1, &arh);

    GuidoLayoutSettings gls = {0};
    GuidoGetDefaultLayoutSettings(&gls);
    GuidoAR2GR (arh, &gls, &desc.handle);

    desc.hdc = &dev;                    // we'll draw on the postscript
device
    desc.page = 1;                      // page to draw
    desc.updateRegion.erase = true;     // and draw everything
    desc.scrollx = desc.scrolly = 0;    // from the upper left page corner
    desc.sizex = wi;
    desc.sizey = he;      // size of the drawing region
  //  desc.isprint = true;

    GuidoOnDraw (&desc);
    GuidoFreeGR(desc.handle);
    GuidoFreeAR(arh);
    GuidoShutdown();
}

Best Regards.
