/CropBox overflows /MediaBox
by Pablo Rodriguez 01 Mar '23

01 Mar '23

Dear list, I have the following source: \nopdfcompression \setupinteractionscreen [width=max] \setuplayout [standard] [backspace=.7\textwidth, cutspace=\cutspace, width=middle] \starttext \startmakeup[page] \null \stopmakeup \startmakeup[standard] \null \stopmakeup \stoptext Boxes are defined in the following objects: 3 0 obj [ 0 0 595.275590072 841.88975789 ] endobj 5 0 obj [ 0 0 595.27559 841.889758 ] endobj 8 0 obj [ 0 0 968.199847 841.889758 ] endobj Page 1 has /MediaBox redirected to object 3 and /CropBox redirected to object 5. Page 2 has /MediaBox redirected to object 3 and /CropBox redirected to object 8. I’m not sure whether the oversized /CropBox in the sample above is a bug triggered by the use of "\setupinteractionscreen[width=fit]". >From the PDF–1.7 specification (https://opensource.adobe.com/dc-acrobat-sdk-docs/standards/pdfstandards/pdf…) The crop, bleed, trim, and art boxes shall not ordinarily extend beyond the boundaries of the media box. If they do, they are effectively reduced to their intersection with the media box. https://wiki.contextgarden.net/PDF_Boxes displays an image of (what I guess) the ordinary case: /CropBox fits inside /MediaBox. Could anyone be so kind to confirm the issue or to explain the rationale behind the oversized /CropBox? Many thanks for your help, Pablo

\setupparagraphs - can they run over two pages?
by jbf 27 Feb '23

27 Feb '23

I have the following setup for side-by-side paras. \defineparagraphs[Two][n=2] \setupparagraphs[Two][1][width=.1\textwidth,style=\bfx,align=tolerant] \setupparagraphs[Two][2][width=.9\textwidth,style=normal,align=tolerant] My difficulty is that while there is only ever just a couple of numbers in the left-hand 'column', the right-hand 'column' may have several lengthy paragraphs. If I have one relatively short \startTwo followed by one that is much longer, it will be forced to start on the next page, leaving too much empty space on the previous page. It is probable that getting this environment to split across pages is not possible. I can try very different approaches (columns, tables) to solve my problem, but I thought I would at least ask first. Julian

Aaligned numbers in a matrix?
by Bruce Horrocks 26 Feb '23

26 Feb '23

I'm using the following MWE to produce a matrix: \definemathmatrix[bmatrix] [matrix:brackets] [simplecommand=bmatrix] \starttext $ a \rightarrow \bmatrix{1, 2, 3, 4; 2, 1, 4, 3; 3,-4, 1,-2; 4,-3, 2,-1} $ \stoptext The columns with negative numbers in are centred and I would rather have them right-aligned so that the digits stack up above each other and the negative signs stick out to the left, so to speak. Is there an easy way to achieve this? — Bruce Horrocks Hampshire, UK

How to add data from another PDF in index?
by Joel 26 Feb '23

26 Feb '23

I am making a textbook and workbook set. I have this custom index using this code, in both the textbook and workbook: % \defineregister[learnedshort][compress=yes] \setupregister[learnedshort][style=sansbold, textstyle=slanted, n=2, pagenumber=yes, indicator=no] % \defineregister[learnedlong][compress=yes] \setupregister[learnedlong][style=sansbold, textstyle=slanted, n=2, pagenumber=yes, indicator=no] % \define[1]\learnedis{% \txt{} \getvalue{#1} \learnedshort{#1} \learnedlong{#1} } \define[1]\learned{% \learnedshort{#1} \learnedlong{\getvalue{#1}} } \starttext \learnedis{blah blah} \input knuth \learnedis{some more} \startchapter[title=Standards] \placelearnedshort \stopchapter \stoptext My question is, can I have references to the Workbook page numbers in the textbook? And visa-versa? For instance, the Textbook index currently looks like this: ------------- Standards blah blah 1 some more 2 -------------- With the data in the Workbook it might look like this: Standards blah blah 1, WB: 1, 3-8 some more 2, WB: 8-9 yet more WB: 10, 12 -------------- Is this possible to merge index information like this? --Joel

Indenting next multi paragraph description
by Alex Leray 23 Feb '23

23 Feb '23

Hi, I'd like to indent next paragraphs in multi paragraph descriptions. For some reason, I can't figure out why this isn't working. Any idea? Here is my code: ### \setupwhitespace[none] \setupindenting[yes, 3em, next] \definedescription[question][ before={\vskip-\parskip}, after={\vskip-\parskip}, width=3em, hang=3, ] \definedescription[answer][ before={\vskip-\parskip}, after={\vskip-\parskip}, width=3em, hang=3, indenting={yes, 3em, next}, % Does nothing indentnext=yes, % Does nothing too ] \starttext \startcolumns[n=2] \startquestion{(T.C.)} \input ward \stopquestion \startanswer{(N.M.)} \input ward \input ward \stopanswer \stopcolumns \stoptext ### Thanks!
