Raster image transparency

Hi all

I have a small raster image (png) xrefed to an Autocad 2012 dwg.  The image is on its own layer and the transparency of the layer is set to 60%.

When I select TPY the image displays correctly on the screen (i.e. semi-transparent).  When I tick Plot transparency in the Plot dialog box and send the plot to our HP Designjet 800 the raster image prints exactly as I want (semi-transparent).

However when  I use the Autodesk pdf writer (Dwg to pdf) the resulting pdf does not have the semi transparent appearance and the raster image appears in all its brilliant colour even though it displays correctly (i.e. semi-transparent) in Print Preview. And, yes, I have ticked the Plot transparency box before sening it to the pdf writer. Other autocad entities such as plines which are semi transparent are fine, its only the raster image that seems to lose its semi-transparent quality.

Any ideas?

Many thanks.

Jeff

Hi Jeff,

 

Do you mind uploading your DWG and PNG files?

 

Cheers,

Luciane

Does it do the same if you plot to a 3rd party PDF driver?

What about the DWG to DWF.PC3 file?

Both CutePdf & PDFCreator maintain the transparency into the pdf.

Hi Jeff,

 

Our developers are aware of the issue and it should be addressed in a future release of the product.

Thanks for letting us know.

 

Cheers,

I just had this same problem occur in AutoCAD 2013.  It is not fixed.

Sorry for the confusion, when I wrote the last reply AutoCAD 2013 had already been developed.

Thanks for your patience on this matter.

Cheers,

Luciane
