Version History

Library

QisMLib Library

• Windows 64 : qismlib64.dll
• Linux 64 : libqism64.so

qismlib v3.25

• New API QisMExploderV3 to compute a density map (in form of tiles) based on the no. vertices contained within. This can be useful for efficient load sharing in multi-threaded queue operations
• Also provides a corresponding QisMScript command explcounter.break_window_by_vertnum

qismlib v3.24.4

• Bug fix: QisMExploder Get_vector_data thread resources were not being freed on Linux resulting in rise in the memory footprint

qismlib v3.24.3

• New API QisMWindowProbe and corresponding script command probe.window
• Misc. bug fixes

qismlib v3.24.2

• Misc. additions to QisMBoolSettings (qismbool.h)
• New QisMScript commands for branching and loops

qismlib v3.24.1

• New QisMBool API (QisMBoolSettingV2 -- qismbool.h) with many more controls to flavor the results of boolean operations
• QisMBStore (qismbstore.h) extended with some utility functions
• New script commands for QisMFile, QisMExploder and QisMBStore

qismlib v3.24

• QisMScript. Built-in support for defining and executing script commands. Script commands can be executed by any application using QisMLib. Any code attached to the QisM system can also add commands. qismscript64.exe is a console app that can be used to run scripts

qismlib v3.23.1

• QisMExplCounter (qismexplcounter.h) has a new extension QisMExplCounterV2 to compute vertex counts upto the specified nesting level

qismlib v3.23

• New API : QisMFileOut (qismfileout.h). A unified interface to write boundaries to disk as GDSII/OASIS (vector) or TIFF/BMP/RAW (images)

qismlib v3.22.1

• Bug fix: QisMExplCounter::Get_counts_hierarchical crashed if the specified cell did not exist

qismlib v3.22

• New API : QisMLibV2::Set_working_dir to change the current working directory for the process using QisMLib

• QisMLibV2 is an extension to the QisMLib class. It can be obtained as follows:

  QisMLibV2* v2 = (QisMLibV2*)(qismlib->QisMLib_cast(2));
  If (NULL == v2) { //error: New API QisMLibV2 not supported }
  

qismlib v3.21

• QisMDrawFlag::IFF_BITMAP8 on Windows generates BMP data (previously DIB). BMP = DIB + BITMAPFILEHEADER so that the image data can be processed by one of the many .bmp processing functions

qismlib v3.20

• Break in backwards compatbility. All applications built with earlier versions of QisMLib MUST be re-built
• Method overloading removed from all classes because of incompatibilities with non-MSVC compilers on Windows
• To prevent accidental use with older QisMLib, QisMLib_initialize_once fn has been replaced by QisMLib_initialize_once_ext so that the run-time will fail immediately. The application does not have to call QisMLib_initialize_once_ext. They can continue to call QisMLib_initialize_once exactly as before. QisMLib_initialize_once is now a macro that redirects to QisMLib_initialize_once_ext

qismlib v3.12

• Internal limit on the number of active files/exploders removed. These are not only contrained by the system resources (or licenses in case of exploders)
• 3.12.1 : Bug-fix in this change that caused a crash during multi-threaded explosion

qismlib v3.11

• New licensed API QisMClipper (qismclipper.h) for computing interaction of boundaries and paths with a set of windows/regions

qismlib v3.10

• New API QisMLog (qismlog.h) for system-wide logging in QisMLib
• Some QisMLib_initialize_once options can be delivered by environment vars

qismlib v3.9

• Break in the API compatibility. All apps/libs using QisMLib 3.9 and it's extensions MUST be re-built using the new header files
• The temp. heade file qismlib_extras.h is no longer available. It's two 'C" functions have been incorporated into QisMFileLoadCtrl class (qismfile.h)
• Bug-fix: QisMBool boolean functions returned error if set A was empty. This has been fixed. Set A can be empty
• Extension to QisMExploder to explode boundaries and cell references

qismlib v3.8

• Bug Fix: Unloading files did not decrement the file index resulting in QisMLib reaching the max. number of files open

qismlib v3.7

• OASIS code is now optimized for multi-threaded use
• New function QisMFileLoadCtrl_ignore_text_scale and to force text scale to 0.0 upon load in order to avoid using text extents in the computation of cell extents just like OASIS
• New function QisMFileLoadCtrl_load_empty_refs to control if the empty refs are loaded. If ignore-text-scale is ON, the load-empty-refs becomes necessary for cells containing only texts since those cell's extents will become 0,0,0,0

qismlib v3.6

• Support for loading multiple files enables. API remains the same. Previously, QisMLib::Load_file unloaded the previously file automatically before loading a new file. Now, each call to QisMLib::Load_file creates a new QisMFile handle
• New QisMExplCounter function that uses hierarchical explosion to get counts much faster then the other method

qismlib v3.5.1

• Build error: Undefined symbol SystemInfo::Get_num_processors()

qismlib v3.5

• New extension api QisMBoolX
• Bug Fix: Multi-threaded access issues affecting QisMDraw::Redraw_image for XPM format

• Bug fix: Error message for license failure

qismlib v3.4

• Bug-fix : Get_vector_data (qismexploder.h) was returning true even if the client interrupted execution via callback return code
• New QisMLib_initialize_once arg (-qismcfg) to specify a config file other than qismlib.cfg or to not load any config at all
• Bug-fix: QisMLib::Load_file crashed if QisMLib::Unload_file was used to close the previous file
• Bug-fix: Undefined reference error for QisMDrawObject::Get_display_vector_data

qismlib v3.3

• Support for creating memory maps (qismfile.h - QisMFileMemoryMaps)
• API to get exploded counts for a cell+layer (QisMFile::Get_cell_layer_exploded_vertices)
• Bug-fix : Exploders were not being freed correctly leading to an error after 512 calls to QisMFile::Create_exploder
• Buf-fix : GDSII/OASIS/Dbload errors were not handled correctly

qismlib v3.2
