From cde5101eb15b24519e89fa500fe37038bc8e2201 Mon Sep 17 00:00:00 2001 From: art-snake Date: Thu, 15 Sep 2016 14:11:09 -0700 Subject: Fix memory leaking on ClosePage. CFX_FontCache refactoring: after this CL: Only one global CFX_FontCache used. Any cached items from it, are released, when its are not used. BUG=79367,48791 The fonts was not cleared after unloading pages. Test pdf: http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf For this file, we have ~5 fonts per page, which equal ~1 Mb per page. In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory. memory usage of PDF Plugin: before this CL: ~660 Mb after this CL: ~100 Mb Review-Url: https://codereview.chromium.org/2158023002 --- xfa/fxbarcode/oned/BC_OnedUPCAWriter.cpp | 32 ++++++++++++-------------------- 1 file changed, 12 insertions(+), 20 deletions(-) (limited to 'xfa/fxbarcode/oned/BC_OnedUPCAWriter.cpp') diff --git a/xfa/fxbarcode/oned/BC_OnedUPCAWriter.cpp b/xfa/fxbarcode/oned/BC_OnedUPCAWriter.cpp index 01660b75c7..12acb5280b 100644 --- a/xfa/fxbarcode/oned/BC_OnedUPCAWriter.cpp +++ b/xfa/fxbarcode/oned/BC_OnedUPCAWriter.cpp @@ -190,8 +190,7 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, if (pOutBitmap) { ge.Create((int)strWidth, iTextHeight, FXDIB_Argb, nullptr); ge.GetBitmap()->Clear(m_backgroundColor); - ge.DrawNormalText(iLen, pCharPos + 1, m_pFont, - CFX_GEModule::Get()->GetFontCache(), (FX_FLOAT)iFontSize, + ge.DrawNormalText(iLen, pCharPos + 1, m_pFont, (FX_FLOAT)iFontSize, &affine_matrix, m_fontColor, FXTEXT_CLEARTYPE); geBitmap.SetDIBits(ge.GetBitmap(), leftPosition, m_Height - iTextHeight); } else { @@ -201,9 +200,8 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, if (matrix) { affine_matrix1.Concat(*matrix); } - device->DrawNormalText( - iLen, pCharPos + 1, m_pFont, CFX_GEModule::Get()->GetFontCache(), - (FX_FLOAT)iFontSize, &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); + device->DrawNormalText(iLen, pCharPos + 1, m_pFont, (FX_FLOAT)iFontSize, + &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); } tempStr = str.Mid(6, 5); iLen = tempStr.GetLength(); @@ -211,8 +209,7 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, if (pOutBitmap) { FX_RECT rect2(0, 0, (int)strWidth, iTextHeight); ge.FillRect(&rect2, m_backgroundColor); - ge.DrawNormalText(iLen, pCharPos + 6, m_pFont, - CFX_GEModule::Get()->GetFontCache(), (FX_FLOAT)iFontSize, + ge.DrawNormalText(iLen, pCharPos + 6, m_pFont, (FX_FLOAT)iFontSize, &affine_matrix, m_fontColor, FXTEXT_CLEARTYPE); geBitmap.SetDIBits(ge.GetBitmap(), leftPosition + 40 * multiple, m_Height - iTextHeight); @@ -224,9 +221,8 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, if (matrix) { affine_matrix1.Concat(*matrix); } - device->DrawNormalText( - iLen, pCharPos + 6, m_pFont, CFX_GEModule::Get()->GetFontCache(), - (FX_FLOAT)iFontSize, &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); + device->DrawNormalText(iLen, pCharPos + 6, m_pFont, (FX_FLOAT)iFontSize, + &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); } tempStr = str.Mid(0, 1); iLen = tempStr.GetLength(); @@ -239,8 +235,7 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, delete ge.GetBitmap(); ge.Create((int)strWidth, iTextHeight, FXDIB_Argb, nullptr); ge.GetBitmap()->Clear(m_backgroundColor); - ge.DrawNormalText(iLen, pCharPos, m_pFont, - CFX_GEModule::Get()->GetFontCache(), (FX_FLOAT)iFontSize, + ge.DrawNormalText(iLen, pCharPos, m_pFont, (FX_FLOAT)iFontSize, &affine_matrix, m_fontColor, FXTEXT_CLEARTYPE); geBitmap.SetDIBits(ge.GetBitmap(), 0, m_Height - iTextHeight); } else { @@ -249,9 +244,8 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, if (matrix) { affine_matrix1.Concat(*matrix); } - device->DrawNormalText( - iLen, pCharPos, m_pFont, CFX_GEModule::Get()->GetFontCache(), - (FX_FLOAT)iFontSize, &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); + device->DrawNormalText(iLen, pCharPos, m_pFont, (FX_FLOAT)iFontSize, + &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); } tempStr = str.Mid(11, 1); iLen = tempStr.GetLength(); @@ -260,8 +254,7 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, delete ge.GetBitmap(); ge.Create((int)strWidth, iTextHeight, FXDIB_Argb, nullptr); ge.GetBitmap()->Clear(m_backgroundColor); - ge.DrawNormalText(iLen, pCharPos + 11, m_pFont, - CFX_GEModule::Get()->GetFontCache(), (FX_FLOAT)iFontSize, + ge.DrawNormalText(iLen, pCharPos + 11, m_pFont, (FX_FLOAT)iFontSize, &affine_matrix, m_fontColor, FXTEXT_CLEARTYPE); geBitmap.SetDIBits(ge.GetBitmap(), leftPosition + 85 * multiple, m_Height - iTextHeight); @@ -273,9 +266,8 @@ void CBC_OnedUPCAWriter::ShowChars(const CFX_WideStringC& contents, if (matrix) { affine_matrix1.Concat(*matrix); } - device->DrawNormalText( - iLen, pCharPos + 11, m_pFont, CFX_GEModule::Get()->GetFontCache(), - (FX_FLOAT)iFontSize, &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); + device->DrawNormalText(iLen, pCharPos + 11, m_pFont, (FX_FLOAT)iFontSize, + &affine_matrix1, m_fontColor, FXTEXT_CLEARTYPE); } FX_Free(pCharPos); } -- cgit v1.2.3
