What a crappy user interface to use is this bug tracker here!
For a willing and well-meaning user to have to deal with this is a total pain in the a*#.
1. Can't you at least use a mono-spaced font?!
2. And tell it not to eat up multiple spaces!
3. And give me a preview of what I've written before I finally submit?
4. And let me edit my posting after I discover a typo or an error?!
5. [... no, I'm not wasting my time any more...]
As it stands, this will be used by me again... ...only in extreme emergencies! |

Thank you for the report. We will investigate asap. Can you check against the latest 0.80.0 ? |

Luigi, I don't know how to check against 0.80.0.
I totally rely on the packages the "Tex Live Utility" gives me (which I update almost daily).
But if there isn't a *totally easy* and *easily revertible* way to update to 0.80.0 I'm not willing to jump through loops here. (I'm already handling other self-compiled software packages on my notebook. But these I *know* how to deal with in case of problems -- everything LaTeX/TeX related I have no clue. I only came to LaTeX/LuaLaTeX via `pandoc`...) |

exiftools 9.46 with your image says
:
Resolution Unit : inches
X Resolution : 1
Y Resolution : 1
:
Image Size : 482x642
The image size is hence 482in x 642in, and both are bigger than 2^16pt (1pt =1/72.27 in)
which is the max dimension accepted by the TeX engines pdftex, xetex, luatex.
In this case the image is not loaded (in luatex) even if the user specifies a transformation matrix that gives an acceptable final dimensions. Note that 1dpi is not wrong by itself
--- 20x20 at 1dpi is perfectly fine --- the limits are on the metric dimensions.
Anyway, from luatex 0.80.0 there is a warning for 1dpi:
LuaTeX warning: The image specifies an unusual resolution of 1dpi by 1dpi.
LuaTeX warning: arithmetic: number too big
LuaTeX warning: arithmetic: number too big |

@LuigiScarso: I know that the image size is 482x642 pixels, and a 1 DPI JFIF setting, if respected, will create an image of 482in x 642in.
That is exactly my argument: scaling the image based on a (most likely) very completely uncontrolled JFIF header setting is not a good idea.
The changed v0.80.0 warning does not help much, sorry. If the lualatex behavior does not change, it will still not create a visible image on the PDF page. |

The image is valid, and as I have said there are 1dpi images that are perfectly fine with luatex. To put the box with the image on the main vertical list, Luatex needs to know its metric dimensions and the only way, when the dpi is known, is to multiply the dpi for the width and the height.
In this case the dimensions are over 2^16pt, and the box cannot be built.
It is supposed that a user knows these features, checking if an image fits into this limit, and acting as consequence if this is not the case.
We agree that it's desirable that a transformation matrix could act before the calculation of the dimensions, but this doesn't solve the problem, as also
impose a scaling to 2^16pt .
This is not a bug, but a feature that could be improved in a next release. |

|
|
Ah, sorry, I meant 32768pt = 2^15pt not 2^16pt. |
|

Also the message
LuaTeX warning: arithmetic: number too big
comes from
scaled ext_xn_over_d(scaled x, scaled n, scaled d)
{
double r = (((double) x) * ((double) n)) / ((double) d);
if (r > DBL_EPSILON)
r += 0.5;
else
r -= 0.5;
if (r >= (double) max_integer || r <= -(double) max_integer)
luatex_warn("arithmetic: number too big");
return (scaled) r;
}
where
#define max_integer 0x7FFFFFFF
so it's related to a value that cannot fit into a scaled
(which is defined as int).
Even if the image fits into a scaled, it can
be still problematic because the \maxdimen is 16383.99998pt ~= 2^14pt . |
|
|
|
it's dangerous to change behaviour of the inclusion and interpretation of fields without much testing, we keep an eye on it but zero or one pixel images are ot common in tex related workflows |
|
|
|
we will not touch the inclusion code; this issue relates to the maximum dimension that tex can handle and 1 dpi is resulting in an overflow ... so be it
(LS/HH) |
