PNG inserted into Autocad

[tkinsley]

I'm having an issue with PNG files inserted into Autocad 2014.

I embed them via MS Paint, select all, copy...Then past into acad with paste special, Picture (Metafile);

When I try to print they sometimes print blank.  I've checked the setvar settings for OLEFAME, FRAME, IMAGEFRAME.  They are on a printable layer.  When they do print, the next time I open acad, I see blank frames.  I've also tried pasting them as Paintbrush Picture and image entity but to no avail.  

If I link them, they will print but when I open them later the images disappear.  But the xref manager shows them still linked.  Reloading does not work either.  

I tried recreating the PNG files.  Tried different machines.

I Tried embedding the files in Autocad 2017 with the same issue.

Hi @tkinsley,

Is there a reason you are using them as OLE objects and not straight images using IMAGEATTACH?

Can you attach some sample files so I can try to duplicate what you are seeing?

Sorry If I was not clear, I'm not using OLE (insertobj). 

I used insert raster image (imageattach) and then also tried paste special.  (imageattach) insert the file as a linked file whereas paste special embeds the file.  Embedding the image file is always preferred since one does not have to deal with external files.

You issue appears to be more of a pathing problem than anything else: when embedded images vanish it's because you unintentionally left an OLE link (or an imageattach reference) that after reopening died and went away.

That's 99.99% accurate. I doubt yours is that 0.01% "something else". If ylu think otherwise then prove it: embed an image in a new file and do what you want. QSAVE, CLOSE and quickly ZIP a copy of the file. Now open it and get it to disappear: if it does, QSAVE, CLOSE and ZIP a a new copy of this file. Post both ZIP files here. A dead link will appear here to us in both your files, a vanishing act 0.01% error will only appear in your second zip here to us.

Thanks you for your time and assistance.

Attached is an autocad file with 3 images embedded (2 subject png files and a random JPG fish pic as test).  The file was started new and at NO TIME was an OLE (insertobj) or insert raster image (imageattach) command ever used in this file.  The three images were all embed using the same process. From Paint, select all, copy and then in acad paste special.  As you can see the images that are PNG are blank and the JPG is not.

Also, your comments about "this percentage" and "that percent"  made no sense?  Not sure what you were trying to say.

Hi @tkinsley,

When you copy/paste to get the image into your drawing it becomes an OLE object as you can see in this:

You might try saving it as an WMF or enhanced WMF and then use WMFin to see if it behaves any differently.

thank you for your input,

Yes I'm aware of how it displays in properties window once you paste an image to embed in the drawings.  The test JPG image also similar but shows up?

By suggesting another image format are you telling me that there is some bug or limitations with using PNG images?

[john.vellek]

Hi @tkinsley,

Try this test for me:

Open your PNG file in MS Paint

Select ALL

Copy

In AutoCAD, Paste Special

Paste as Image Entity.

Does this behave better for you when you close and then reopen your file?

[pendean]

>>>... From Paint, select all, copy and then in acad paste special...<<<
Instead of PASTESPEC command, simply use PASTECLIP command (ctrl+V) and that should eliminate your OLE connections.

 
There is no user-unattended mechanism to turn a simply pasted image into an connected OLE in AutoCAD after the fact. BUT all inserted images list as OLE.

[tkinsley]

Thanks, Yes I previously tried all the different format during my test phase and that didn't resolve issue.

[tkinsley]

Thanks Dean,

I tried the crtl-v to paste the file in autocad but it disappeared completely, no frame.  I tried this and the other suggestion with different PNG files, created from a different source, but issues still exist.

Hi @tkinsley,

The obvious answer to me, since you indicated that JPG files work, is to use JPG files 🙂

But, let's see if we can nail this down. Try using this PIXLR software to save the PNG to see if it behaves differently. I have been reading that a 32-bit PNG might work better or at least differently.

[EDIT] Another solution that seems to work for some conditions is to insert the image into a dwg file. Then, insert that file into your drawing.

here you go. Copy the image and use the command "pastespec". The image will be imbeded.

If the image is PNG file you should fill it with white using photoshop. and save it to jpeg. and now you can insert the image to the Cad file with white background .and for removing the frame please refer to : https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoC...

1. Click Modify menu Object Image Frame.
2. To hide image boundaries, enter 0; to show and plot image boundaries, enter 1; to show image boundaries but not plot them, enter 2.
