我想使用IplImage來產生一個1-bit 單通道非0即1的黑白影像我的程式碼 IplImage *image; CvSize size = cvSize( 320, 240); char array[320*240]; image = cvCreateImageHeader( size, IPL_DEPTH_1U, 1 ); for(int x = 0 ; x < 320*240 ; x++){ array[ x ] = x%2; } cvSetImageData( image, array, image->widthStep ); cvSaceImage( "testImage.tiff", image ); 但卻得到錯誤訊息 OpenCV ERROR: Input image depth is not supported by function () in function cvGetMat, ../../../cxcore/src/cxarray.cpp(2799) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... called from cvUnregisterType, ../../../cxcore/src/cxpersistence.cpp(4933) Terminating the application... 在東問西查後，cvSaceImage()的說明文件裡有提到 Only 8-bit single-channel or 3-channel (with 'BGR' channel order) images can be saved using this function. 看到這個我心涼一半了我主要的應用只是儲存影像而已所以並不會對影像做操作由於是大量的儲存影像所以用 8-bit 來存，空間會吃很兇請問各位大大有甚麼辦法解決這個問題嗎O_Q ? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.166.50.16
