Bug in 7.3, can't export to TIF file

Jorge Garcia wrote on Fri, 04 December 2015 12:49

I have just now reported this to the devs.

I just installed version 7.6, and this is still broken.

What seems to be happening is that Eagle produces a TIFF file with CCITT

(fax) compression when monochrome is checked.  It produces a more normal

TIFF file when monochrome is unchecked, since CCITT is only for 1 bit per

pixel images.  Lots of software doesn't support the ancient CCITT

compression type of TIFF files, or interprets such files wrongly.  For

example, if I open such a file from Eagle with MS Paint on a Windows 7

system, it shows the values inverted.  The schematic lines are white and

the background is black.

Please just have Eagle produce TIFF files as it did in version 5.  I am

disappointed that this wasn't fixed in version 7.6.

Once again, DON'T MAKE GRATUITOUS CHANGES.  You will inevitably break

something that someone has relied on.

However, you broke something else in the process.  Now the TIF file gets

written using CCITT (old fax) compression when the monochrome box is

checked.  This was never the case before.  Lots of software doesn't handle

this compression scheme, including what I call from ULPs and scripts to do

various things.  LZW compression or LZW with forward differencing are fine

and pretty much universally supported.

 

PLEASE RETURN THE TIF FILE WRITING FEATURE TO THE WAY IT WAS IN VERSION 5.

Hi Olin,

Sorry for the delay, haven't been able to get to the forums the last few

days.

I have just now reported this to the devs.

Best Regards,

Jorge Garcia

This seems to be a problem that came with the newer Qt version

we are using since EAGLE 7.3.0. We will check this......

I just installed latest Eagle for 64-bit Linux with the Element 14 free trial key on an Xubuntu 14.04 LTS x64 stable system.  When I try to export the Arduino project to ANY graphics format, I get the same result i.e. "Out of memory while writing ...".  So, this is not just Windows.

In version 7.3 on Windows 7 64 bit, there seems to be a bug in exporting a

board to a TIF image file.  In the board editor, if I run "EXPORT IMAGE

\temp\a.tif" I always get a popup that says "Out of memory while writing

'/temp/a.tif'".  This happens regardless of resolution.  For example,

"EXPORT IMAGE \temp\a.tif 50" fails the same way, even though that would

have only required 320 x 552 pixels in my case.
