tiff2pdf fails with page of code - centos

Hi I am trying to use tiff2pdf to convert some tiff files captured by the fax application in asterisk to PDF
I have installed tiff2pdf by the following method:
sudo yum install ghostscript libtiff
When I execute the command to convert I get the following:
[root#cloud01 tmp]# tiff2pdf FAX-443439791001-2015-09-26_00-34-40.tiff

Am I missing a library or some other dependency?

From the man page:
tiff2pdf opens a TIFF image and writes a PDF document to standard output.
Perhaps if you tried:

Matlab: create band matrix with repeating and alternating values

Let us say that I have 7 values: a, b, c, d, e, f and g
I would like to construct an m by n matrix in this way:
[ a b c d 0 0 0 0 . . . .
[ b e f g 0 0 0 0 . . . .
[ c f a b c d 0 0 . . . .
[ d g b e f g 0 0 . . . .
[ 0 0 c f a b c d 0 0 . .
[ 0 0 d g b e f g 0 0 . .
[ . . 0 0 c f a b c d . .
[ . . 0 0 d g b e f g . .
And so forth...
Therefore, the desired matrix is symmetrical. Values a and e alternate on the main diagonal; values b and f alternate on the 1st upper diagonal; values c and g alternate on the 2nd upper diagonal; values d and 0 alternate on the 3rd upper diagonal. I would like to be able to specify the matrix size with m by n parameters.
I used to do this easily with the SparseArray and Band functions in Mathematica, but I cannot find equivalent functions in Matlab. Would there be an efficient way to construct this kind of matrix in Matlab?

You can use spdiags to specify the upper diagonals in a sparse matrix and then add the transpose of the strictly upper triangular part for exact symmetry:
>> n = 6;
>> a = 1;b = 2;c = 3;d = 4;e = 5;f = 6;g = 7;
>> n = 6;
>> A = spdiags(repmat([[a;e] , [f;b] , [c;g] , [0;d]],n/2,1),0:3,n,n);
>> A = A + triu(A,1).';
>> issymmetric(A)
ans =
1
>> full(A)
ans =
1 2 3 4 0 0
2 5 6 7 0 0
3 6 1 2 3 4
4 7 2 5 6 7
0 0 3 6 1 2
0 0 4 7 2 5
You might notice I flipped b/f and 0/d to adjust for the filling behavior; there may be a better way to do this.
For non-square matrices with potentially odd dimension number, I would build the minimum-sized square sparse matrix that has the actual one as a sub-matrix and mask out the unneeded portion at the end:
>> m = 13;
>> n = 6;
>> p = max([m,n]);
>> p = p + mod(p,2); % added to make p even.
>> A = spdiags(repmat([[a;e] , [f;b] , [c;g] , [0;d]],p/2,1),0:3,p,p);
>> A = A + triu(A,1).';
>> A = A(1:m,1:n);
>> full(A)
ans =
1 2 3 4 0 0
2 5 6 7 0 0
3 6 1 2 3 4
4 7 2 5 6 7
0 0 3 6 1 2
0 0 4 7 2 5
0 0 0 0 3 6
0 0 0 0 4 7
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
It's a tad inefficient to build, but easy and straight-forward.

You can use the spdiags function
Using numbers instead of letters (sparse does not support symbols) like this:
m = 10;
n = 10;
B = repmat([1:4;[5:7 0]],n/2,1);
B=[B(:,end:-1:2) B];
d=-3:3;
A = spdiags(B,d,m,n);
full(A)
which outputs:
1 6 3 0 0 0 0 0 0 0
2 5 2 7 4 0 0 0 0 0
3 6 1 6 3 0 0 0 0 0
4 7 2 5 2 7 4 0 0 0
0 0 3 6 1 6 3 0 0 0
0 0 4 7 2 5 2 7 4 0
0 0 0 0 3 6 1 6 3 0
...
Explanation:
The B matrix contains the values needed on the diagonals in its columns. It is first constructed using B = repmat([1:4;[5:7 0]],n/2,1); which makes the first two rows repeat n/2 times. At that point it looks like:
1 2 3 4
5 6 7 0
1 2 3 4
5 6 7 0
1 2 3 4
5 6 7 0
1 2 3 4
...
Then it is mirrored to give it the diagonals that are in the lower diagonal part using B=[B(:,end:-1:2) B]; which makes it look like:
4 3 2 1 2 3 4
0 7 6 5 6 7 0
4 3 2 1 2 3 4
0 7 6 5 6 7 0
4 3 2 1 2 3 4
0 7 6 5 6 7 0
4 3 2 1 2 3 4
...
These are the diagonals passed to the spdiags function.
The end is a MATLAB keyword which refers to the last column or row. That indexing line says, in words: "Take all the rows of B, and the columns starting from the end, going back 1 step at a time until the second column, and place that submatrix before B." That is how the mirroring is accomplished.

Convert a matrix of type char to type logical in matlab

Hello I have a char matrix that represents a binary numbers. For example:
0000
1010
0111
.
.
.
1010
How can I convert it to a logical matrix?

You can compare it with character '1'
>> A=['0101';'1011']
A =
0101
1011
>> A=='1'
ans =
0 1 0 1
1 0 1 1

Is this what you want?
a = {'0000'; '1010'; '0111'};
b = logical(double(cell2mat(a)) - 48);
gives,
>> b
b =
0 0 0 0
1 0 1 0
0 1 1 1
>> class(b)
ans =
logical

Try
b_bin = logical(b(:)'-'0')
if b is the name of your matrix.

MATLAB: indexing a 3d matrix with another 3d matrix

Say I have two 3D matrices of same dimension (3x3x2):
A =
ans(:,:,1) =
0 0 0
0 0 0
0 0 0
ans(:,:,2) =
0 0 0
0 0 0
0 0 0
B =
ans(:,:,1) =
0 1 0
0 1 0
0 1 0
ans(:,:,2) =
1 0 0
1 0 0
0 0 1
I would like to index the last page (third dimension) of A where the corresponding page of B equals 1 and turn those values into 2, so that A becomes:
A =
ans(:,:,1) =
0 0 0
0 0 0
0 0 0
ans(:,:,2) =
2 0 0
2 0 0
0 0 2
How can I do it? Is there an easy way?

This could be one approach to set the elements in last page in the third dimension of A at places where the last page in the third dimension of B have 1's -
A(find(B(:,:,end)==1) + numel(B) - numel(B(:,:,1))) = 2
Sample run -
%// Starting input, A
A(:,:,1) =
0.2187 0.1097 0.4046 0.3658
0.1058 0.0636 0.4484 0.7635
A(:,:,2) =
0.6279 0.9329 0.1920 0.6963
0.7720 0.9727 0.1389 0.0938
A(:,:,3) =
0.5254 0.8611 0.3935 0.7413
0.5303 0.4849 0.6714 0.5201
%// Input, B
B(:,:,1) =
2 2 1 1
1 1 3 2
B(:,:,2) =
3 3 3 2
2 2 3 1
B(:,:,3) =
1 1 3 3
2 1 2 2
%// Output, A
A(:,:,1) =
0.2187 0.1097 0.4046 0.3658
0.1058 0.0636 0.4484 0.7635
A(:,:,2) =
0.6279 0.9329 0.1920 0.6963
0.7720 0.9727 0.1389 0.0938
A(:,:,3) =
2.0000 2.0000 0.3935 0.7413
0.5303 2.0000 0.6714 0.5201

Manipulating a PDF file with different rotations and scaling with Perl's PDF::API2

I'm using CAM::PDF to merge several PDF files. This works fine. Now I need to add a stamp on each page using PDF::API2. This works fine for some pages, but not for others.
PDF files created with wkhtmltopdf seem to have their coordination system flipped and the scaling is off as well.
When running through the pages I add a stamp like this:
my $pdf2 = PDF::API2->open_scalar($pdf_data);
my $page_count = $pdf2->pages;
for my $i ( 1 .. $page_count ) {
my $page = $pdf2->openpage($i);
my $content = $page->gfx();
my $text = $page->text();
$content->linewidth(2);
$content->rectxy( 5, 10, 140, 40 );
$content->stroke;
my $font = $pdf2->ttfont('calibri.ttf');
$text->scale( 1.0, 1.0 );
$text->font( $font, 12 );
$text->translate( 10, 14 );
$text->text( sprintf( 'PAGINA %d VAN %d', $i, $page_count ) );
$text->translate( 10, 26 );
$text->text('some ID');
}
my $pdf_data = $pdf2->stringify;
Now, the pages that are from the wkhtmltopdf have a tiny box with even tinier text in the top left corner (but inside the page margins) and it's mirrored. The non-wkhtmltopdf page has a properly sized box with properly sized text in the bottom left corner (ignoring page margins).
Using $content->scale and $content->rotate(180) I can properly display the stamp on the pages created by wkhtmltopdf. But then the other pages are messed up.
So, is there any way to make sure that each document has the same orientation, rotation and scale on all pages?

++Htbaa has already answered HOW to get around this problem.
I've had a chance to look at wkhtmltopdf. This answer describes WHY it's output is causing problems.
I wrote a trivial /tmp/hw.html
<html>
<body>hello world!</body>
</html>
Then created and uncompressed a pdf:
% wkhtmltopdf --version
Name:
wkhtmltopdf 0.9.9
...
% xvfb-run wkhtmltopdf /tmp/hw.html /tmp/hw.pdf
% pdftk /tmp/hw.pdf output /tmp/hw1.pdf uncompress
Here's what the page content (object 8) looks like.

endstream endobj
The answer is in the very first instruction on the page /GSa gs is setting the graphics state, occurs before the first q instruction (save graphics state).
So the page is being left in an untidy graphics state. When further content is then added to the PDF by PDF::API2, it is using the altered state.

The answer pointed out by #snoopy seems to fix the problem I'm experiencing. Text and image size of the stamp-pdf/overlay-pdf are the same size on all pages.

I searched the web but i haven't find a solution, so i tried to generate my files with Zend_PDF but i got the same message and not a pdf file.
Please help!
Thanks

Looks like you're not setting your headers correctly, I'm guessing you're using render() in Zend_PDF so try adding this in place on your current render()
$this->getResponse()->setHeader('Content-type', 'application/x-pdf', true);
$this->getResponse()->setHeader('Content-disposition', 'inline; filename=my-file.pdf', true);
$this->getResponse()->setBody($pdf->render());
