[NTG-context] 'overprint' swallows leading number
Hi,
title says it all.
(ConTeXt 2016.12.28 17:55)
minimal example:
\starttext
\startluacode
local bCI,eCI = context.startcolorintent, context.stopcolorintent
bCI({"overprint"})context("1.2345\\crlf")eCI() -- also no 'overprint'
for that text part in the PDF
bCI({"overprint"})context("First number is missing.\\crlf")eCI()
\stopluacode
\stoptext
-
I also get an overflow exception with one of my tables, but I could
'fix' that with '\setupalign[nothyphenated]'. The table is complex (lua
generated), so no minimal example at hand. Anyhow, here the error
message (space-ali.mkiv).

Maybe related to the prior bug (also overprinting numbers in the TABLE),

IM will apply a default interpretation of 72dpi unless you override it (e.g. -density 300x300 -units pixelsperinch)." Testing: convert original.tif -rotate 45 rotated.png keeps the original density. 1) original.tif was 6000x6000; rotated.png is 8488x8488 (2400dpi) 2) converting to rotated.tif fails convert: TIFF: negative image positions unsupported rotated.tif @ error/tiff.c/WriteTIFFImage/3609. 3) converting to rotated.pdf does produce a much reduced resolution image. Indeed, PDF is container, not the best format for manipulating bitmap images. I take two approaches to this: 1) I manipulate/modify the images explicitly "upstream" before including them in ConTeXt, using any of my favorite tools; or 2) I manipulate/modify the images using MetaPost, within ConTeXt. This gives very satisfactory results and does not rely on ImageMagik.

Thanks, that fixed it. The overflow still occurs, will look deeper into it.
