Bug in 7.3, can't export to TIF file

Jorge Garcia wrote on Wed, 01 June 2016 12:15

Here's a sample of what is produced by the fix. Let me know if this

works.

I already replied previously that this sample file works.

I can now report that version 7.7 produces usable TIF files both in

monochrome mode and not.  Thanks for fixing this.

I'm not using V7, but for what I can see

- They massively hardened the autorouter's usage for no reason.

- They broke some ULPs. They even decided to not give you a hint of why

it might not work, the ULPs just don't work.

- You can't switch assembly variants in the board editor any longer.

- They turned EAGLE into adware. (Hint: The guys assembling the

prototypes for me are using the freeware version)

Try V6.60, in my experience, it's the best version so far.

 

Too late now anyway,

Your V7 key will also work with V6.

Graphics speed, for example when dragging the layout with the middle mouse

button (wheel) but this depends

on the hardware. The Eagle team is aware of this.

Also, with V6, allmost all ulp's work. With V7, many ulp's are broken

because of the new hierarchy option.

The sad thing about Eagle is, that when you need a certain feature, they

(the Cadsoft team) point you to

an ulp.

But when you complain about bugs in an ulp, they act like it's not a part

of Eagle.

It looks they don't test the ulp's which are installed by default when they

release a new version.

Actual 6.6

because is has NO hierarchical structure (HS) that hardly works in

schematics and not at all in boards.

I'm not gonna pay for less than half of a new "feature" HS in  version 7

and  no one knows  when this will be working properly, perhaps in

version 8 or 9? Or will it ever?

I don't blame cadsoft for this kind of business because they are  not

the own boss anymore. If this business continues, in version 13 we might

have a new feature like "we have added another semicolon in the

description".

By the way, The FILE > EXPORT menu still won't accept "I" to go to

the

"image" entry, as it did in version 5.  A number of similar things

that

broke from version 5 to 7 (I never used 6) are still broken in

7.6.

 

I wasn't aware of this issue. I have reported it as well and will

follow

up once I hear something.

That's just one of several similar ones that I picked off the top of my

head.

Also off the top of my head, there's another like this in the library

editor.  Alt-L,D and Alt-L,S get you to devices and symbols respectively.

However, Alt-L,P doesn't get you to packages.  That's because someone had

the brilliant idea to use P as the shortcut key to two different menu

entries, even though the menu isn't that long and a little bit of thought

would have allowed for unique keys for each entry.  This has been broken

for a while, since version 5 at least.

C'mon guys.  This stuff isn't hard, it just takes someone to actually care

about keyboard usability.  There are quite a number of such things all thru

Eagle, and my impression is that the list gets bigger every release.  Don't

get me started on the keyboard (un)usability of the auto-router, especially

the new interface.

Yes, this works fine.  I enabled extra debug messages for TIFF files and

got the following:

C:\temp>image_info a.tif

TIFF image file directory 1, 12 entries:

  image_width = 1072

  image_length = 1567

  bits_per_sample = 1

  Compression: 5 (LZW)

  Photometric interpetation: 1 (black to white)

  strip_offsets = 8

  orientation = 1

  strip_byte_counts = 12021

  x_resolution = 150.00

  y_resolution = 150.00

  Planar configuration: 1 (whole pixels together)

  Resolution unit: 2 (inch)

Image file is C:\temp\a.tif.

X,Y image size = 1072,1567 pixels.  DX/DY aspect ratio = 0.684.  ALPHA,

RED,

GREEN, BLUE precision = 0,1,1,1 bits/pixel.  File type is "TIF".

Not only is this format much more standard, you will even get good

compression.  LZW on single bit pixels should do a really good job of

compressing the large background areas.  The file contains 1,679,824

pixels, but only contains a total of 97,568 bits, which comes out to 17:1

compression, and that ignores the TIFF file header that is never

compressed.  This is not to say that compression is really all that

important, but mostly to show you aren't giving up anything by doing this.

I doubt CCITT would get you that kind of compression ratio.

Thanks for getting this done.
