2020-12-14ImageSize: use exif width and height when available.John MacFarlane1-0/+13
After the move to JuicyPixels, we were getting incorrect width and heigh information for some images (see #6936, test-3.jpg). The correct information was encoded in Exif tags that JuicyPixels seemed to ignore. So we check these first before looking at the Width and Height identified by JuicyPixels. Closes #6936.
2020-12-13ImageSize: use JuicyPixels to extract size...John MacFarlane1-305/+8
...for png, jpeg, gif, instead of doing our own binary parsing. See #6936.

2020-11-23ImageSize: default to DPI 72 if the format specifies DPI of 0.John MacFarlane1-1/+7
This shouldn't happen, in general, but it can happen with JPEGs that don't conform to the spec. Having a DPI of 0 will blow up size calculations (division by 0). Closes #6880.
2020-03-15Use implicit Prelude (#6187)Albert Krewinkel1-2/+0
* Use implicit Prelude The previous behavior was introduced as a fix for #4464. It seems that this change alone did not fix the issue, and `stack ghci` and `cabal repl` only work with GHC 8.4.1 or newer, as no custom Prelude is loaded for these versions. Given this, it seems cleaner to revert to the implicit Prelude. * PandocMonad: remove outdated check for base version Only base versions 4.9 and later are supported, the check for `MIN_VERSION_base(4,8,0)` is therefore unnecessary. * Always use custom prelude Previously, the custom prelude was used only with older GHC versions, as a workaround for problems with ghci. The ghci problems are resolved by replacing package `base` with `base-noprelude`, allowing for consistent use of the custom prelude across all GHC versions.

2020-02-07More in-depth refactoring and cleanup (#6123)Joseph C. Sible1-3/+1
* Avoid duplicating the dash case * Pull common functions out of case branches * Make sure list lengths are only calculated once * Use unless * Simplify parseURIReference' and avoid an unnecessary call to length * Use <$> instead of reimplementing it * Use swap instead of reimplementing it * Remove eta-expansion that's been unnecessary since 90f5dd8 * Use tailDef instead of reimplementing it * Use second instead of fmap, per @tarleb
2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc1-37/+38
PR #5884. + Use pandoc-types 1.20 and texmath 0.12. + Text is now used instead of String, with a few exceptions. + In the MediaBag module, some of the types using Strings were switched to use FilePath instead (not Text). + In the Parsing module, new parsers `manyChar`, `many1Char`, `manyTillChar`, `many1TillChar`, `many1Till`, `manyUntil`, `mantyUntilChar` have been added: these are like their unsuffixed counterparts but pack some or all of their output. + `glob` in Text.Pandoc.Class still takes String since it seems to be intended as an interface to Glob, which uses strings. It seems to be used only once in the package, in the EPUB writer, so that is not hard to change.
2019-03-21Improve pdfSize in ImageSize by ignoring all whitespace in /MediaBox command ↵richarddavis1-1/+4
(#5383) This fix ignores all whitespace in the PDF /MediaBox line so that a wider range of PDF sizes can be read. This improves fix to #4322.

2019-03-01Remove license boilerplate.John MacFarlane1-18/+0
The haddock module header contains essentially the same information, so the boilerplate is redundant and just one more thing to get out of sync.
2019-02-04Add missing copyright notices and remove license boilerplate (#5112)Albert Krewinkel1-2/+2
Quite a few modules were missing copyright notices. This commit adds copyright notices everywhere via haddock module headers. The old license boilerplate comment is redundant with this and has been removed. Update copyright years to 2019. Closes #4592.

- Export `inEm` from ImageSize [API change]. - Change `showFl` and `show` instance for `Dimension` so extra decimal places are omitted. - Added `Em` as a constructor of `Dimension` [API change]. - Allow `em`, `cm`, `in` to pass through without conversion in HTML, LaTeX. Closes #3450.

2015-11-09Revert "Use -XNoImplicitPrelude and 'import Prelude' explicitly."John MacFarlane1-1/+0
This reverts commit c423dbb5a34c2d1195020e0f0ca3aae883d0749b.
2015-11-08Use -XNoImplicitPrelude and 'import Prelude' explicitly.John MacFarlane1-0/+1
This is needed for ghci to work with pandoc, given that we now use a custom prelude. Closes #2503.
2015-10-14Use custom Prelude to avoid compiler warnings.John MacFarlane1-1/+0
- The (non-exported) prelude is in prelude/Prelude.hs. - It exports Monoid and Applicative, like base 4.8 prelude, but works with older base versions. - It exports (<>) for mappend. - It hides 'catch' on older base versions. This allows us to remove many imports of Data.Monoid and Control.Applicative, and remove Text.Pandoc.Compat.Monoid. It should allow us to use -Wall again for ghc 7.10.
