2016-07-24Use actual type instead CFX_Deletableweili
Change two places that used CFX_Deletable to use actual types. This makes the type more obvious, and avoids unnecessary casts. Review-Url: https://codereview.chromium.org/2180443002
2016-07-06Change class member variables in raw pointer type into unique_ptrweili
Also did some cleanups such as removing an unused member variables and some unused structs. BUG=pdfium:518 Review-Url: https://codereview.chromium.org/2119013002
2016-06-23Improve hint table validation checks.thestig
Check required hint table dictionary entries and make sure they: - Exist. - Are of the right type. Along the way: - Fix FX_atonum() to not have a non-const pass-by-ref param. - Simplify code in CPDF_StreamContentParser. - Make CPDF_Number::IsInteger() a const method.

2016-06-13Make code compile with clang_use_chrome_plugin (part I)weili
This change contains files in core/fpdfapi directory. This is part of the efforts to make PDFium code compilable by Clang chromium style plugins. The changes are mainly the following: -- move inline constructor/destructor of complex class/struct out-of-line; -- add constructor/destructor of complex class/struct if not explicitly defined; -- add explicit out-of-line copy constructor when needed; -- move inline virtual functions out-of-line; -- Properly mark virtual functions with 'override'; -- some minor cleanups; BUG=pdfium:469 Review-Url: https://codereview.chromium.org/2060973002

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

2016-05-25Remove CFX_PrivateData from CPDF_Pagetsepez
CFX_PrivateData served two purposes here: The first was to hold an opaque pointer to the corresponding page structure in the next higher layer, of which it knows no details. Introduce an empty CPDF_Page::View class to represent this higher class, so as to get type safety while preserving layering. The second was to hold an opaque render context, which it also happened to own. Make this a CFX_Deletable to help with management. Also remove an unused inheritance from CFX_PrivateData in CPDF_Annot. Review-Url: https://codereview.chromium.org/2008553008

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.

2016-04-27Standardize on ASSERT.dsinclair
There are currently three ways to assert in the code (ASSERT, FXSYS_assert and assert). This CL standardizes on ASSERT. The benefit of ASSERT is that it can be overridden if the platform requies and we can pickup the Chromium version if it has already been defined in the build. This does change behaviour. Currently FXSYS_assert is always defined but ASSERT is only defined in debug builds. So, the FXSYS_assert's would fire in Release builds. That will no longer happen.

This CL removes the interfaces: * IPDF_ObjectRenderer * IPDF_OCContext * IPDF_RenderModule * IPDF_PageModule The CPDF_RenderModule was just wrapping new and delete calls.

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. Review URL: https://codereview.chromium.org/1886263003
2016-04-14Make CPDF_Dictionary methods take CFX_ByteString argumentstsepez
This will help avoid duplicate allocation of CFX_ByteStrings when the caller already has one. It may seem counter-intuitive that requiring the caller to pass an allocated CFX_ByteString rather than a static CFX_ByteStringC would improve the situation, but due to the idiosyncrasies of std::map, the CPDF_Dictionary methods must always do an allocation under the covers which can't be avoided. The changed callers in this CL are places where we would previously demote to CFX_ByteStringC and then allocate a a duplicate CFX_ByteString in the dictionary method.

2016-04-12flesh out gradient shaderscaryclark
Using these webpages as guides http://www.globelegislators.org/pdfjs/test/pdfs/alphatrans.pdf http://www.antennahouse.com/antenna1/wp-content/uploads/2015/07/background-image-gradient-1.pdf flesh out the gradient shaders to include the PostScript Type 0 sampling function and to include radial gradients. This CL makes rendering these pages agree with Adobe Reader output. Some of these examples use an Extend array to clip the gradient. Skia does not currently support this natively, so construct the clip manually for now. Other PDF pages may construct gradients using alternate mechanisms -- this code will continue to be refactored as those come to light. In particular, this CL sets up the clip and matrix differently for axial gradients and radial gradients -- while it makes sense to do it one way only, I prefer to defer until I have more examples to work with.

2016-04-11Remove CPDF_Object::GetConstString and overridestsepez
GetConstString() has sharp edges in that when applied to a CPDF_Number, it must return null whereas GetString() returns a the stringified number, because of the inability to control the lifetime of the underlying allocated string. Deleting this method showed several places where we actually wanted a *String, not a *StringC, so we were re-allocating a string we already had. Review URL: https://codereview.chromium.org/1879683002
2016-04-11Use std::vector as internal storage for CPDF_ArrayWei Li

2016-04-04Make down-conversion explicit from CFX_ByteString to CFX_ByteStringC.tsepez

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
