From e6ff2ebfaa19421c8d932f4d275548156ae2e13c Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Fri, 24 Aug 2018 21:55:46 +0000 Subject: Rename CFX_DIBSource to CFX_DIBBase. It is not a source from which you can get CFX_DIBs, but rather a base class from which all DIBs inherit. Do the same thing for the CPDF_DIBSource wrapper class. Mechanical change apart from adding a one-line comment in cfx_dibbase.h Change-Id: Id2bde87813ca301d9fafc55ce08d703dfc6a7184 Reviewed-on: https://pdfium-review.googlesource.com/41352 Reviewed-by: Lei Zhang Commit-Queue: Tom Sepez --- core/fxge/agg/fx_agg_driver.cpp | 8 +- core/fxge/agg/fx_agg_driver.h | 6 +- core/fxge/cfx_defaultrenderdevice.h | 4 +- core/fxge/cfx_renderdevice.cpp | 23 +- core/fxge/cfx_renderdevice.h | 22 +- core/fxge/dib/cfx_dibbase.cpp | 1259 ++++++++++++++++++++++++++++ core/fxge/dib/cfx_dibbase.h | 140 ++++ core/fxge/dib/cfx_dibextractor.cpp | 6 +- core/fxge/dib/cfx_dibextractor.h | 4 +- core/fxge/dib/cfx_dibitmap.cpp | 24 +- core/fxge/dib/cfx_dibitmap.h | 24 +- core/fxge/dib/cfx_dibsource.cpp | 1262 ----------------------------- core/fxge/dib/cfx_dibsource.h | 139 ---- core/fxge/dib/cfx_filtereddib.cpp | 2 +- core/fxge/dib/cfx_filtereddib.h | 10 +- core/fxge/dib/cfx_imagerenderer.cpp | 2 +- core/fxge/dib/cfx_imagerenderer.h | 4 +- core/fxge/dib/cfx_imagestretcher.cpp | 6 +- core/fxge/dib/cfx_imagestretcher.h | 8 +- core/fxge/dib/cfx_imagetransformer.cpp | 4 +- core/fxge/dib/cfx_imagetransformer.h | 6 +- core/fxge/dib/cfx_scanlinecompositor.h | 2 +- core/fxge/dib/cstretchengine.cpp | 4 +- core/fxge/dib/cstretchengine.h | 4 +- core/fxge/dib/cstretchengine_unittest.cpp | 4 +- core/fxge/fx_dib.h | 2 +- core/fxge/renderdevicedriver_iface.cpp | 4 +- core/fxge/renderdevicedriver_iface.h | 12 +- core/fxge/skia/fx_skia_device.cpp | 41 +- core/fxge/skia/fx_skia_device.h | 14 +- core/fxge/win32/cfx_psrenderer.cpp | 8 +- core/fxge/win32/cfx_psrenderer.h | 8 +- core/fxge/win32/fx_win32_device.cpp | 8 +- core/fxge/win32/fx_win32_print.cpp | 18 +- core/fxge/win32/win32_int.h | 26 +- 35 files changed, 1557 insertions(+), 1561 deletions(-) create mode 100644 core/fxge/dib/cfx_dibbase.cpp create mode 100644 core/fxge/dib/cfx_dibbase.h delete mode 100644 core/fxge/dib/cfx_dibsource.cpp delete mode 100644 core/fxge/dib/cfx_dibsource.h (limited to 'core/fxge') diff --git a/core/fxge/agg/fx_agg_driver.cpp b/core/fxge/agg/fx_agg_driver.cpp index 9166fbb0c8..063f36d600 100644 --- a/core/fxge/agg/fx_agg_driver.cpp +++ b/core/fxge/agg/fx_agg_driver.cpp @@ -144,7 +144,7 @@ void RgbByteOrderTransferBitmap(const RetainPtr& pBitmap, int dest_top, int width, int height, - const RetainPtr& pSrcBitmap, + const RetainPtr& pSrcBitmap, int src_left, int src_top) { if (!pBitmap) @@ -1491,7 +1491,7 @@ RetainPtr CFX_AggDeviceDriver::GetBackDrop() { return m_pBackdropBitmap;
