Dear Friend,

       How to Rasterize the ai Files in  Grayscale Using the function sAIRasterize->Rasterize().

If anybody knows the Rasterize the ai file. please guide me.

You can use Rasterize Suite. You should call AIRasterizeSuite::Rasterize() with AIRasterizeSettings provided, where you can set type (AIRasterizeType) to kRasterizeGrayscale.

Quick example:

group should bee existing AIArtHandle - with type kGroupArt

AIErr error;
AIRasterizeSettings settings;
AIColorConvertOptions colorConvertOptions;
AIArtHandle art;

settings.type = kRasterizeGrayscale;
settings.resolution = <desired resolution>; // here enter resolution
settings.antialiasing = 5;
settings.options = kRasterizeOptionsDoLayers;
settings.ccoptions = colorConvertOptions;
settings.preserveSpotColors = true;

error = sAIRasterize->Rasterize(
  artSet,
  &settings,
  &rect,
  kPlaceInsideOnTop,
  group,
  &art,
  NULL,
);

You will then get art with type kRasterArt. You can write it to file with compression (JPEG, PNG) using Data Filter Suite.

Thanks for your reply..!

I tried these code but Error is occur

Please clarify the below code has any mistake.

AppContext appContext(g_SPPluginRef);
AIErr result = kNoErr;
ArtMatcher artMatcher(1);
artMatcher.SetSpec(0, kAnyArt, 0, 0);
artMatcher.GetMatchingArt();
AIArtSet artset;
sAIArtSet->NewArtSet(&artset);
AIRealRect artBounds;
for (int nIndex = 0; nIndex < artMatcher.GetNumMatches(); ++nIndex)
{
short type;
ai::FilePath fPath;
AIArtHandle art = artMatcher.GetMatchedArt(nIndex);
sAIArt->GetArtType(art,&type);

sAIArtset->AddArtToArtSet(artset, art);
}
AIArtHandle artHandle, rasterHandle;
sAIArt->GetFirstArtOfLayer(NULL, &artHandle);
AIRasterizeSettings settings;
AIColorConvertOptions colorConvertOptions;
AIArtHandle art;

settings.type = kRasterizeGrayscale;
settings.resolution = 72; // here enter resolution
settings.antialiasing = 5;
settings.options = kRasterizeOptionsDoLayers;
settings.ccoptions = colorConvertOptions;
settings.preserveSpotColors = true;

result = sAIRasterize->Rasterize(
artset,
&settings,
&artBounds,
kPlaceInsideOnTop,
artHandle,
&art,
NULL
);

I forgot to mention you about ArtSet, but I see you find it out. You didn't set artBounds, call AIRasterizeSuite::ComputeArtBounds to calculate art bounds. Which error code you get?
