High RAM-Usage when exporting to PNG (resulting in [IMer]-ImageOptimizationError)

[Guest]

Hello,

first of all the example of my source code:

     if(myParams){       
 
          error = sAIActionManager->AIActionSetStringUS(myParams, kAIExportDocumentNameKey, ai::UnicodeString("C:\\test\\test2.png") );
      
          error = sAIActionManager->AIActionSetString(myParams, kAIExportDocumentFormatKey, "Adobe PNG Format");     
          error = sAIActionManager->AIActionSetString(myParams, kAIExportDocumentExtensionKey, "png");     
          error = sAIActionManager->AIActionSetBoolean(myParams, kAIExportDocumentSaveAllKey, false);     
          error = sAIActionManager->AIActionSetBoolean(myParams, kAIExportDocumentSaveMultipleArtboardsKey, true);    
          error = sAIActionManager->AIActionSetString(myParams, kAIExportDocumentSaveRangeKey, "5");
          error = sAIActionManager->RecordActionEvent(kAIExportDocumentAction, kDialogOff, myParams);
 
   
          if (sAIActionManager->InRecordMode){
                sAIActionManager->PlayActionEvent(kAIExportDocumentAction, kDialogOff, myParams);
          }

 
     }
    
     return kNoErr;

When calling PlayActionEvent it takes a long time and the RAM-Usage increases to more than 1 GB. Although the Illustrator-File is only 1,5 MB. The Destination-File (test2-05.png) doesn't exist, after the process is finished there is only a test2-05.png.tmp$$ File (0 bytes) an i get a Message with the Error Code: IMer.

How I can pass the sAIActionManager the ImageOptimization for a File? It is required to export exactly one Artboard!

Can anyone help me?

I have a similar Problem. My PNG-Files are empty and I doesn't get an error message. I translated the error number it describe an IMer-Error too. It is an error in the ImageOpt.

Has anyone an idea please?

Have you tried using AIImageOptSuite  (MakePNG24) instead to complete this?

Take a look at this suite, you will find what you are looking for.

I used both solutions, but finally I chose the last one.

Hi,

thank you for yout answer. Yes now it is so, that I use the method MakePNG24 fro the AIImageOptSuite. The problem I have now is, when the quality of the image is too high (eg. antialias = true and resolution 300).

Then the AIImageOptSuie creates PNG-Files with 0 Bytes. The AIImageOptSuite givs an errorcode. It is IMer. It's an error in the Image Optimization. And when I try it with the normal export function in the menubar, it export not all files, sometimes I get the same Exception from the Adobe Illustrator (native).

Some pictures are working fine and some not. Only if I take a low quality, It runs everytimes, but this is not the way I want go.

Do you have any ideas? Is it a bug in AI?

Thank you for request, and a happy new year from Germany - Dortmund!!

You can set AIImageOptPNGParams2 properties to set those parameters:

ex:

params.versionOneSuiteParams.resolution = ......;

params.antialias = ......;

Just take a look at AIImageOptPNGParams2, there is a lot to be configured.

Is the AIDataFilter used by the MakePNG24 method set correctly?

Have you set the crop property of AIImageOptPNGParams2 ? correctly set?

I used not to have such bugs for any art I wanted to export as PNG.

Regards,

Thomas.

this shoud be helpful:

  AIErr result =kNoErr;

  AIDataFilter* dstFilter = 0;

  AIDataFilter* filter = 0;

  ai::UnicodeString file(filepath);   //file path c

  ai::FilePath fileP(file);

  try

          { 

                      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;

                      // still to be configured, with your own values!!

                      AIImageOptPNGParams2 params;

                      params.versionOneSuiteParams.interlaced = ;

                      params.versionOneSuiteParams.numberOfColors = ;

                      params.versionOneSuiteParams.transparentIndex = ;

                      params.versionOneSuiteParams.resolution = ;

                      params.versionOneSuiteParams.outAlpha = ;

                      params.versionOneSuiteParams.outWidth = ;

                      params.versionOneSuiteParams.outHeight = ;  

                      params.antialias = ;

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

                      params.cropBox = ;

                      params.backgroundIsTransparent = ;

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

                      aisdk::check_ai_error(result);

                      if (dstFilter)

                      {

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

                                     aisdk::check_ai_error(result);

                      }

          }

          catch(ai::Error& ex)

          {

                  //Handle error

          }

  return result;

I didn't understand any of your coding, so that solution was out for me.

However, I was able to open the AI file directly into Photoshop as a Photoshop PDF and save it out as the PNG needed.

Thank you for having the question out there to be searched.
