Abstract

A picture to be printed is prepared by DTP software and is stored into layer L0 of the file F which is distributed to respective correctors. The first corrector writes correcting indication K1 onto layer L1, the second corrector writes correcting indication K2 onto the layer L2 and the third corrector writes correcting indication K3 onto the layer L3. For the respective layers, respective passwords are to be set for ensuring securities. In order to display or to edit a specific layer, it is required to input a proper password. Layer information ranging over plural files can be united within a single file and are handled with a unified manner.

Claims

1. A presentation apparatus for two-dimensional picture information, comprising:

display means for displaying a predetermined picture in a two-dimensional display area;

memory means for preserving contents to be displayed in said display area as data in a state divided into plural layers; and

display control means for reading out data with respect to a designated layer from said memory means in accordance with a layer designation inputted by an operator, preparing a picture to be displayed on the basis of the data which has been read out and delivering the prepared picture to said display means to display it;

wherein said display control means has a function to set a password with respect to a specific layer based on demand of the operator and, when a layer in which the password is set is designated, to display contents of said designated layer in the display area provided that said password is inputted.

4. A presentation apparatus for two-dimensional picture information as set forth in claim 1:

wherein data of a specific layer is preserved within the memory means in an enciphered state, whereby in the case where collation of the password is succeeded, the data is decoded so that contents of said specific layer are displayed in a state where they can be recognized, while in the case where collation of the password is failed, the data is not decoded so that contents of said specific layer are displayed in a state where they cannot be recognized.

6. A computer readable recording medium on which there is recorded a program for allowing a computer to function as the memory means and the display control means as set forth in claim 1.

2. A presentation apparatus for two-dimensional picture information, comprising:

display means for displaying a predetermined picture in a two-dimensional display area;

memory means for preserving contents to be displayed in said display area as data in a state divided into plural layers;

display control means for reading out data with respect to a designated layer from said memory means in accordance with a layer designation inputted by an operator, preparing a picture to be displayed on the basis of the data which has been read out and delivering the prepared picture to said display means to display it; and

editing means for editing data with respect to a designated layer in accordance with a layer designation and an editing instruction inputted by the operator and storing edited data into said memory means;

wherein said editing means has a function to set a password with respect to a specific layer based on demand of the operator and, when a layer in which the password is set is designated, to edit contents of said designated layer provided that said password is inputted.

5. A presentation apparatus for two-dimensional picture information as set forth in claim 2, further comprising:

file synthesis means having a function to combine a first file and a second file into a third file;

wherein said first file consists of a first group of data having at least one layer and a second group of data having at least one layer, and said second file consists of a third group of data having at least one layer and a fourth group of data having at least one layer, said first group of data and said third group of data being same; and

wherein said file synthesis means produces said third file by gathering said first, second and fourth group of data.

7. A computer readable recording medium on which there is recorded a program for allowing a computer to function as the memory means, the display control means and the editing means as set forth in claim 2.

3. A presentation apparatus for two-dimensional picture information, comprising:

display means for displaying a predetermined picture in a two-dimensional display area;

memory means for preserving contents to be displayed in said display area as data in a state divided into plural layers;

display control means for reading out data with respect to a designated layer from said memory means in accordance with a layer designation inputted by an operator, preparing a picture to be displayed on the basis of the data which has been read out and delivering the prepared picture to said display means to display it; and

editing means for editing data with respect to a designated layer in accordance with a layer designation and an editing instruction inputted by the operator and storing edited data into said memory means;

wherein said display control means has a function to set a display password with respect to a specific layer based on demand of the operator and, when a layer in which the display password is set is designated, to display contents of said designated layer in the display area provided that said display password is inputted; and

wherein said editing means has a function to set an editing password with respect to a specific layer based on demand of the operator and, when a layer in which the editing password is set is designated, to edit contents of said designated layer provided that said editing password is inputted.
