After upgrading to 3.8.3 Create ER Diagram is OK, but export as jpeg activates a pop up: “Error exporting image”.
Trying again: “Reason: No more handles”.

[Riyad Kalla]

“No more handles” is an SWT/OS system level error that can occur. Check your log file (workspace dir)\.metadata\.log for more details to help us figure out what happened.

[Greg]

Let us know about your system profile by using the “Insert” system profile button. Since the “No more handles” is a OS level error we need to know your OS, etc. The system profile will give us all that information.

[support-michael]

How large is your ER (tables & rels)? I believe “no more handles” in this case is an indication that the SWT is unable to handle the image conversion due to its size. We are researching this issue.

Sorry, I must still learn…

This problem alawys seems to be tied into a malfunction with the browser widget… very strange.

What is your system’s default browser? If you have mozilla installed, can you try reinstalling Mozilla 1.6 instead of 1.7+ and see if that fixes it? (it works under Linux)

[Brian Fernandes]

I’m not sure about the browser widget being a problem … but here is the scoop on the SWT no more handles.

The internal bitmaps that are used to store the image have a limit on size. ie. they can only be a maximum of 16 MB. This was supposed to be a limitation on only Windows 95 / 98 / ME – but I think a similar limitation might exist with 2000 and XP as well. I have an XP system myself and I have similar problems. If your image is going to occupy more than 16 MB – it won’t work this time around, sorry. Linux exports are obviously not affected by this issue and I’ve seen large diagrams being exported w/o problem.

You can calucate the bitmap memory requirement by using something like width x height x bpp / 8 (bpp = bits per pixel, usually 16, 24 or 32 – check your screen depth)

Sorry about the limitation atm – it will be removed in the next release.

Thanks,
Brian.

[lzechmei]

Browser: IE 5.50
Image size sounds plaisible, the picture is rather big (but it is a real project with real size).

As mentioned earlier, the matter is not urgent. I wanted simply to help you eliminating a bug.

[mstrong4867]

I’m having the same problem.

Did you ever resolve this one?

[Riyad Kalla]

This didn’t make it into 3.8.4 unfortunately.

[tibi]

yes i have the same problem. at the beginning i could get arround it when i moved al the object close together 😳 but now it does not fit any more . 🙁

when will it be fixed?

[tibi]

i would be happy with a work arround of getting two half images

[tibi]

one more thing when you get the error it seems to persist even when the image gets smaller. you will notic that the error message apears quite fast. when you restart eclipse and made your image small enough it could all work again. (in my case!)

[sm_vaid]

I experienced this problem also, and just to confirm that it was resolved by re-saving the image with a smaller color depth. I did this by reducing the color depth to 16 bit in the Windows display properties.

😯

[Brian Fernandes]

Your 16 bit trick is a good one 🙂
A 16 bit image would take half the space of a 32 bit image, so you can get away with larger images…

We hope to fix this problem soon – sorry for the inconvenience caused.
Brian.
