/****************************************************************************** ** Filename: Host.h ** Purpose: This is the system independent typedefs and defines ** Author: MN, JG, MD ** Version: 5.4.1 ** History: 11/7/94 MCD received the modification that Lennart made ** to port to 32 bit world and modify this file so that it ** will be shared between platform. ** 11/9/94 MCD Make MSW32 subset of MSW. Now MSW means ** MicroSoft Window and MSW32 means the 32 bit worlds ** of MicroSoft Window. Therefore you want the environment ** to be MicroSoft Window and in the 32 bit world - ** _WIN32 must be defined by your compiler. ** 11/30/94 MCD Incorporated comments received for more ** readability and the missing typedef for FLOAT. ** 12/1/94 MCD Added PFVOID typedef ** 5/1/95 MCD. Made many changes based on the inputs. ** Changes: ** 1) Rearrange the #ifdef so that there're definitions for ** particular platforms. ** 2) Took out the #define for computer and environment ** that developer can uncomment ** 3) Added __OLDCODE__ where the defines will be ** obsoleted in the next version and advise not to use. ** 4) Added the definitions for the following: ** FILE_HANDLE, MEMORY_HANDLE, BOOL8, ** MAX_INT8, MAX_INT16, MAX_INT32, MAX_UINT8 ** MAX_UINT16, MAX_UINT32, MAX_FLOAT32 ** 06/19/96 MCD. Took out MAX_FLOAT32 ** 07/15/96 MCD. Fixed the comments error ** Add back BOOL8. ** ** (c) Copyright Hewlett-Packard Company, 1988-1996. ** Licensed under the Apache License, Version 2.0 (the "License"); ** you may not use this file except in compliance with the License. ** You may obtain a copy of the License at ** http://www.apache.org/licenses/LICENSE-2.0 ** Unless required by applicable law or agreed to in writing, software ** distributed under the License is distributed on an "AS IS" BASIS, ** WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. ** See the License for the specific language governing permissions and ** limitations under the License. */ #ifndef TESSERACT_CCUTIL_HOST_H_ #define TESSERACT_CCUTIL_HOST_H_ /****************************************************************************** ** IMPORTANT!!! ** ** ** ** Defines either _WIN32, __MAC__, __UNIX__, __OS2__, __PM__ to ** use the specified definitions indicated below in the preprocessor settings. ** ** ** ** Also define either __FarProc__ or __FarData__ and __MOTO__ to use the ** specified definitions indicated below in the preprocessor settings. ** ** ** ** If a preprocessor settings is not allow in the compiler that is being use, ** then it is recommended that a "platform.h" is created with the definition ** of the computer and/or operating system. ******************************************************************************/ #include #include "platform.h" /* _WIN32 */ #ifdef _WIN32 #include #undef min #undef max #endif #include // PRId32, ... #include // int32_t, ... /********************************************************/ /* __MAC__ */ #ifdef __MAC__ #include /*----------------------------*/ /*----------------------------*/ #endif /********************************************************/ #if defined(__UNIX__) || defined( __DOS__ ) || defined(__OS2__) || defined(__PM__) /*----------------------------*/ /* FarProc and FarData */ /*----------------------------*/ /*----------------------------*/ #endif /***************************************************************************** ** ** Standard GHC Definitions ** *****************************************************************************/ #ifdef __MOTO__ #define __NATIVE__ MOTO #else #define __NATIVE__ INTEL #endif //typedef HANDLE FD* PHANDLE; // definitions of portable data types (numbers and characters) typedef int8_t inT8; typedef uint8_t uinT8; typedef int16_t inT16; typedef uint16_t uinT16; typedef int32_t inT32; typedef uint32_t uinT32; typedef int64_t inT64; typedef uint64_t uinT64; typedef float FLOAT32; typedef double FLOAT64; typedef unsigned char BOOL8; #if defined(_WIN32) /* MinGW defines the standard PRI... macros, but MSVS doesn't. */ #if !defined(PRId32) # define PRId32 "d" #endif #if !defined(PRId64) # define PRId64 "I64d" #endif #endif /* _WIN32 */ #define MAX_INT8 0x7f #define MAX_INT16 0x7fff #define MAX_INT32 0x7fffffff #define MAX_UINT8 0xff #define MAX_UINT16 0xffff #define MAX_UINT32 0xffffffff #define MAX_FLOAT32 std::numeric_limits::max() #define MIN_INT8 static_cast(0x80) #define MIN_INT16 static_cast(0x8000) #define MIN_INT32 static_cast(0x80000000) #define MIN_UINT8 0x00 #define MIN_UINT16 0x0000 #define MIN_UINT32 0x00000000 // Minimum positive value ie 1e-37ish. #define MIN_FLOAT32 std::numeric_limits::min() // Defines #ifndef TRUE #define TRUE 1 #endif #ifndef FALSE #define FALSE 0 #endif // Return true if x is within tolerance of y template bool NearlyEqual(T x, T y, T tolerance) { T diff = x - y; return diff <= tolerance && -diff <= tolerance; } #endif // TESSERACT_CCUTIL_HOST_H_
