otra pregunta con respecto al análisis de PDF ... Acabo de leer PDF Referencia versión 1.7 "5.3.1 Operadores de posicionamiento de texto" y estoy un poco confundido.Obteniendo posición de texto mientras analiza PDF con Cuarzo 2D
Escribí un código para obtener la matriz de transformación y la posición inicial del texto.
CGPDFOperatorTableSetCallback (table, "MP", &op_MP);//Define marked-content point
CGPDFOperatorTableSetCallback (table, "DP", &op_DP);//Define marked-content point with property list
CGPDFOperatorTableSetCallback (table, "BMC", &op_BMC);//Begin marked-content sequence
CGPDFOperatorTableSetCallback (table, "BDC", &op_BDC);//Begin marked-content sequence with property list
CGPDFOperatorTableSetCallback (table, "EMC", &op_EMC);//End marked-content sequence
//Text State operators
CGPDFOperatorTableSetCallback(table, "Tc", &op_Tc);
CGPDFOperatorTableSetCallback(table, "Tw", &op_Tw);
CGPDFOperatorTableSetCallback(table, "Tz", &op_Tz);
CGPDFOperatorTableSetCallback(table, "TL", &op_TL);
CGPDFOperatorTableSetCallback(table, "Tf", &op_Tf);
CGPDFOperatorTableSetCallback(table, "Tr", &op_Tr);
CGPDFOperatorTableSetCallback(table, "Ts", &op_Ts);
//text showing operators
CGPDFOperatorTableSetCallback(table, "TJ", &op_TJ);
CGPDFOperatorTableSetCallback(table, "Tj", &op_Tj);
CGPDFOperatorTableSetCallback(table, "'", &op_apostrof);
CGPDFOperatorTableSetCallback(table, "\"", &op_double_apostrof);
//text positioning operators
CGPDFOperatorTableSetCallback(table, "Td", &op_Td);
CGPDFOperatorTableSetCallback(table, "TD", &op_TD);
CGPDFOperatorTableSetCallback(table, "Tm", &op_Tm);
CGPDFOperatorTableSetCallback(table, "T*", &op_T);
//text object operators
CGPDFOperatorTableSetCallback(table, "BT", &op_BT);//Begin text object
CGPDFOperatorTableSetCallback(table, "ET", &op_ET);//End text object
Así que esta es la salida después del almuerzo aplicación:

Si alguien está familiarizado con matriz de texto y los operadores de posicionamiento de texto sería bueno para explicar cómo todos los que trabajo.
¿Cómo se calcula la posición del texto (o glifo?) Utilizando Tm (matriz de transformación y otros datos)?
has averiguado cómo utilizar los operadores? ¡Gracias! – pt2ph8
