default resolution when exporting as png

[christianbrugeron]

Hi

We are using cc2014 and cc2015 and both have not a way for setting PNG export resolution. We must rely on a previous export by the user. If not set, it takes a long time to export ununusable 112bytes PNG files!

Any way to avoid that?

Thanks

Hi,

Which method of which suite are you actually using for making your export?

There is definitely a way to set resolution parameter depending on how you do that.

Best regards,

Thomas.

Hi

Here is my code:

err = sAIActionManager->AINewActionParamValue(&fActionParamValueRef);

//ne doit pas être null,

https://forums.adobe.com/thread/915571?start=0&tstart=0

err =

sAIActionManager->AIActionSetStringUS(fActionParamValueRef,

kAIExportDocumentNameKey, ai::UnicodeString(exportPath));

err =

sAIActionManager->AIActionSetStringUS(fActionParamValueRef,

kAIExportDocumentFormatKey, ai::UnicodeString("Adobe PNG Format"));

err = sAIActionManager->AIActionSetString(fActionParamValueRef,

kAIExportDocumentExtensionKey, "png");

err =

sAIActionManager->AIActionSetBoolean(fActionParamValueRef,

kAIExportDocumentSaveAllKey, false);

err =

sAIActionManager->AIActionSetBoolean(fActionParamValueRef,

kAIExportDocumentSaveMultipleArtboardsKey, true);

err = sAIActionManager->AIActionSetString(fActionParamValueRef,

kAIExportDocumentSaveRangeKey, range);

err =

sAIActionManager->AIActionSetBoolean(fActionParamValueRef,

kAIPDFRoundTripKey, false);

err =

sAIActionManager->PlayActionEvent(kAIExportDocumentAction, kDialogOff,

fActionParamValueRef);

Without a proper manual initialisation by exporting a PNG (and

correcting default values), exporting fails.

The same is true with a fresh installation of Illustrator.

Thank you for your help

Have you had a look at AIImageOptimization.h, which includes AIImageOptSuite::AsPNG and AIImageOptSuite::MakePNG24. I haven't used them myself, but they include arguments for setting parameters like resolution.

[christianbrugeron]

I have heard of this suite but I think it is note related to the export actions.

Do I have to rewrite the export code?

As leoTaro said, you should definitely take a look at AIImageOptimization.h and use MakePNG24 method.

Take a look at AIImageOptPNGParams2 and AIImageOptPNGParams structs, which are used by MakePNG24.

This way you could set the image resolution

AIErr result = kNoErr;

AIDataFilter* dstFilter = 0;

AIDataFilter* filter = 0;

......

result = sAIDataFilter->NewFileDataFilter(fileP, "write", 'prw', 'PNGf', &filter);

aisdk::check_ai_error(result);

result = sAIDataFilter->LinkDataFilter(dstFilter, filter);

aisdk::check_ai_error(result);

dstFilter = filter;

AIImageOptPNGParams2 params;

params.versionOneSuiteParams.interlaced = ...;

params.versionOneSuiteParams.numberOfColors = ....;

params.versionOneSuiteParams.transparentIndex = ...;

params.versionOneSuiteParams.resolution = 300;

params.versionOneSuiteParams.outAlpha = ...;

params.antialias = ConfigurationManager::GetAntialias();

/* A cropping box for the art. If empty or degenerate, do not crop. */

params.cropBox = bounds;

params.backgroundIsTransparent = ConfigurationManager::GetBackgroundIsTransparentProperty();

result = sAIImageOpt->MakePNG24 (art, dstFilter, params, MyRasterizeProgressProc);

aisdk::check_ai_error(result);

....

if (dstFilter)

{

  result = sAIDataFilter->UnlinkDataFilter (dstFilter, &dstFilter);

  aisdk::check_ai_error(result);

}

I hope this will be helpful.

Thomas.

So, is it working?

Did you use MakePNG24 ?

[christianbrugeron]

I was on another project, i'll try this afternoon (Paris time).

Thanks
