2016-06-02Fix all the code which has duplicate variable declarationsweili
When there are duplicate variable declarations, the inner names shadow the outter ones. This is error prone and harder to read. Remove all the instances found by /analyze. BUG=chromium:613623, chromium:427616 Review-Url: https://codereview.chromium.org/2027273002
2016-06-01Change CFX_Font::GetPsName() to return a CFX_ByteString.thestig
So everyone can avoid doing Byte to WideString conversions. Also remove CFX_GEFont::GetPsName() and deduplicate a couple of GetPsName() calls. Review-Url: https://codereview.chromium.org/2019173002

2016-05-17Don't use LCD antialiasing if Fontconfig doesn't support hintingthomasanderson
Some Freetype implementations (like the one packaged with Fedora) do not support hinting due to patents 6219025, 6239783, 6307566, 6225973, 6243070, 6393145, 6421054, 6282327, and 6624828; the latest one expires 10/7/19. This makes LCD antialiasing very ugly, so we instead fall back on NORMAL antialiasing.

2016-05-13Make CFX_ByteString(const CFX_ByteStringC&) explicit.tsepez
Add missing helper function to CFX_ByteTextBuf to avoid the anti-pattern CFX_ByteString(sBuf.AsStringC()), using the name "Make" to indicate there's an allocation going on in this case. Change some method arguments to take pre-existing ByteStrings where possible. Review-Url: https://codereview.chromium.org/1977093002

2016-04-14Rename CFX_ByteTextBuf::GetByteString() to AsStringC().tsepez
Do the same for CFX_WideTextBuf as well. The name is confusing because these return CFX_ByteStringC, not CFX_ByteString. The AsStringC naming gives parallelism with the string types themselves, and may help to indicate that the result is only good for the lifetime of the object being operated upon.

2016-04-12Remove ICodec_* Interfaces.dsinclair
All of the ICodec_* interfaces had a single implementation. This CL removes the interfaces and uses the concrete classes in their place. BUG=pdfium:468 Review URL: https://codereview.chromium.org/1876023003
2016-04-12Record all fonts, not just one per charset.dsinclair
Attempting to open bug_434.pdf on my Linux box would fail with: ../../xfa/fxfa/app/xfa_fwltheme.cpp:96: virtual FWL_ERR CXFA_FWLTheme::Initialize(): Assertion `__null != m_pCalendarFont' failed. I tracked the regression back to [1]. The issue seems to be in CFX_FontManager::AddInstalledFont we will only add one font for a given Charset. In my case I end up loading 6 charsets, but the fonts are all strange ones. When I open the PDF, it fails to find 'Arial' because I've registered these other fonts. To fix this I changed the m_FaceArray into a struct of {name, chraset}. Then we record all fonts into this list and search over that list for the charset when needed. This allows bug_434.pdf to open and the test to pass successfully. 1- https://pdfium.googlesource.com/pdfium/+/fe73e7849b8b4ce49408d2f52f3fc29b370b82b5 Review URL: https://codereview.chromium.org/1874433002

2016-04-08Rename both As{Byte,Wide}StringC() helpers to AsStringC().tsepez
The naming is redundant given the base type, and will stand in the way of consolidating Byte and Wide code. BUG= Review URL: https://codereview.chromium.org/1862123003
2016-04-06Make wide strings use StringData templatetsepez
Shuffled the order of methods in fx_basic_wstring.cpp to match those in fx_basic_bstring.cpp. The way to review this patch is to diff those two files against each other. They are beginning to converge. Re-ordered some parameters in Concat() so that the string comes before its length. It feels wrong otherwise. Review URL: https://codereview.chromium.org/1846793002

2016-04-04Make down-conversion explicit from CFX_ByteString to CFX_ByteStringC.tsepez
Having this happen implicitly can be dangerous because the lifetime has to be considered; we should have caught the "red bots" in https://codereview.chromium.org/1847333004/#ps60001 at compile time. Review URL: https://codereview.chromium.org/1853233002
2016-04-04Support the device font cachecaryclark
Reuse the Skia typeface on sucessive text draw calls. This reduces the SKP size by 100x for some documents. Note that this does not use a smart pointer for the Skia typeface object. The downside of doing so is that it requires all clients that include fx_font.h to also have access to Skia. In this specific case, it is preferable to have a forward declared class to isolate Skia from the rest of PDFium.

2016-03-31Re-enable all the windows warnings except 4267weili
The code is changed or had been changed to no longer generate these warnings. It is safe to re-enabled these warnings. In this code change, we fixed some code which generates warnings 4018 (signed/unsigned mismatch) and 4146 (unary minus operator applied to unsigned type, result still unsigned). Warning 4333 (right shift by too large amount, data loss) and 4345 (an object of POD type constructed with an initializer of the form () will be default-initialized) are no longer generated. The same setting is applied and verified for GN build as well. BUG=pdfium:29 Review URL: https://codereview.chromium.org/1849443003
2016-03-29Code change to avoid signed/unsigned mismatch warnings.Wei Li

2016-03-25support gradients and stroke+fillcaryclark
To draw paths that are stroked and filled with a pair of colors, reduce the fill by the width of the stroke. This is implemented with path ops subtracting the resolved stroke shape from the fill shape. This permits rendering the result without requiring an offscreen bitmap. The implementation for stroke+fill requires a new entry into the graphics engine, so a bit was added to device caps for that. Extract the gradient information out of the axial gradient function descriptions, and when possible, use Skia to draw the linear gradient directly. This requires making the function descriptions non-opaque, and adding a bit to device caps for another entry into the graphics engine. BUG= Review URL: https://codereview.chromium.org/1828283002
2016-03-25Cleanup some extern method declarations.dsinclair
This CL removes _FPDFAPI_GetInternalFontData which is not implemented, FWL_PostMessageToMainRoop which has no body and the PostMessage which was the only caller. FWL_ShowCaret is moved to the only place where it's used. BUG=pdfium:112 Review URL: https://codereview.chromium.org/1827343003
2016-03-24Added bounds checking to GetNameFromTT to handle corrupt files.Tom Sepez
Patch by forshaw. This patch adds bounds checking to the names buffer passed to GetNameFromTT. There are observed crashes in this function where data is read outside of the bounds allocated and passed to GetNameFromTT. There's no reason that this function should ever try and read outside of the allocated bounds.
