2018-10-29Do bilinear interpolation for "huge" images.chromium/3596Lei Zhang
Simply downsampling produces really poor renderings. Use bilinear interpolation to make the rendering look better at the cost of being a bit slower. Roll DEPS for testing/corpus/ to 5a68e878 to pick up the updated test expectations from this CL.

2018-10-26Replace int flags with struct FXDIB_ResampleOptions.Lei Zhang
Using bit values in an int may not be reliable, since different parts of the code can interpret the bits differently. e.g. FXDIB_DOWNSAMPLE and RENDER_FORCE_DOWNSAMPLE are defined in different places, but can be used interchangeably because they just happen to have the same value. It works but is rather fragile. Instead, use a struct of bools to explicitly define what different bits mean. Remove FXDIB_DOWNSAMPLE and friends.

- A valid matrix is always passed in, so make the parameter const-ref. Since it is not obvious who owns the passed in matrix, make a copy with the corresponding matrix member. - Since the matrix parameter is const-ref, CFX_DIBBase::TransformTo() can also have a const-ref matrix parameter. - |flags| should be uint32_t, since |m_Flags| is. - |pClips| is only used inside the ctor, so remove |m_pClip|.
