Rotate command not currently available

[Orson_Bushnell]

I am creating an automation plug-in that needs to rotate the image. Here is the code to call the eventRotate command:

{

PIActionDescriptor rotation_desc;

sPSActionDescriptor->Make(&rotation_desc)

double degrees = 15;

SPErr rotate_error = sPSActionDescriptor->PutUnitFloat(rotation_desc, keyAngle, unitAngle, degrees); // No error here.

rotate_error = sPSActionControl->Play(&result, eventRotate, rotation_desc, plugInDialogSilent); // Returns error -25920.

if (rotate_error != 0)

display error message

}

The result of the Play call is a rotate_error of -25920, (The command "Rotate" is not currently available.)

Changing plugInDialogSilent to plugInDialogDisplay produces the same user interaction as choosing Image->Rotate Canvas->Arbitrary… from the menu, except that it then fails with error -25920.

How do I rotate an image from an automation plug-in?

Here is what Listener outputs for me and works on CS5. Your code failed for me so please check out this block of code.

SPErr PlayeventRotate(/*your parameters go here*/void)

{

PIActionDescriptor result = NULL;

DescriptorTypeID runtimeKeyID;

DescriptorTypeID runtimeTypeID;

DescriptorTypeID runtimeObjID;

DescriptorTypeID runtimeEnumID;

DescriptorTypeID runtimeClassID;

DescriptorTypeID runtimePropID;

DescriptorTypeID runtimeUnitID;

SPErr error = kSPNoError;

// Move this to the top of the routine!

PIActionDescriptor desc0000000000000120 = NULL;

error = sPSActionDescriptor->Make(&desc0000000000000120);

if (error) goto returnError;

// Move this to the top of the routine!

PIActionReference ref0000000000000038 = NULL;

error = sPSActionReference->Make(&ref0000000000000038);

if (error) goto returnError;

error = sPSActionReference->PutEnumerated(ref0000000000000038, classDocument, typeOrdinal, enumFirst);

if (error) goto returnError;

error = sPSActionDescriptor->PutReference(desc0000000000000120, keyNull, ref0000000000000038);

if (error) goto returnError;

error = sPSActionDescriptor->PutUnitFloat(desc0000000000000120, keyAngle, unitAngle, 33);

if (error) goto returnError;

error = sPSActionControl->Play(&result, eventRotate, desc0000000000000120, plugInDialogSilent);

if (error) goto returnError;

returnError:

if (result != NULL) sPSActionDescriptor->Free(result);

if (desc0000000000000120 != NULL) sPSActionDescriptor->Free(desc0000000000000120);

if (ref0000000000000038 != NULL) sPSActionReference->Free(ref0000000000000038);

return error;

}
