DOCUMENT PROCESSING APPARATUS AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING PROGRAM
A document processing apparatus includes an execution unit that executes text selection processing for selecting text data from an electronic document, and a display controller that performs, when the text data is not included in the electronic document, control so as to display an indication that execution of the text selection processing is disabled before a user attempts to execute the text selection processing.
1 . A document processing apparatus, comprising:
an execution unit that executes text selection processing for selecting text data from an electronic document; and
a display controller that performs, when the text data is not included in the electronic document, control so as to display an indication that execution of the text selection processing is disabled before a user attempts to execute the text selection processing.
2 . The document processing apparatus according to claim 1 , wherein, when the text data is not included in the electronic document, the display controller performs control so as to display an indication that an operation image for transition to the text selection processing is not selectable.
3 . The document processing apparatus according to claim 2 , wherein, when the text data is not included in the electronic document and when a cursor is moved onto the operation image for transition to a state in which the text selection processing is enabled, the display controller performs the control so as to display the indication that the execution of the text selection processing is disabled.
4 . The document processing apparatus according to claim 1 , wherein, when the text data is not included in the electronic document, the display controller performs control so as to display information indicating that the execution of the text selection processing is disabled while the information is superposed on an image of the electronic document.
5 . The document processing apparatus according to claim 4 , wherein, when transition is made to a state in which the text selection processing is enabled, the display controller performs the control so as to display the information indicating that the execution of the text selection processing is disabled while the information is superposed on the image of the electronic document.
6 . The document processing apparatus according to claim 1 , wherein, when the text data is included in a partial area of the electronic document, the display controller performs control so as to display, in a distinguishable manner, the area where the text data is included and an area where the text data is not included.
7 . The document processing apparatus according to claim 6 , wherein, when transition is made to a state in which the text selection processing is enabled, the display controller performs the control so as to display, in a distinguishable manner, the area where the text data is included and the area where the text data is not included.
8 . The document processing apparatus according to claim 1 , wherein, when a page of the electronic document to be displayed is switched and when the text data is not included in the page, the display controller performs the control so as to display the indication that the execution of the text selection processing is disabled.
9 . The document processing apparatus according to claim 1 , further comprising:
an acquisition unit that acquires presence/absence information related to presence or absence of the text data in each page when the electronic document is displayed; and
a memory that stores the presence/absence information acquired by the acquisition unit.
10 . The document processing apparatus according to claim 9 , wherein the acquisition unit collectively acquires pieces of the presence/absence information in all pages.
11 . The document processing apparatus according to claim 9 , wherein the acquisition unit acquires the presence/absence information every time a page is switched.
12 . The document processing apparatus according to claim 9 , further comprising an addition unit that adds the presence/absence information acquired by the acquisition unit to the electronic document as attribute information.
13 . The document processing apparatus according to claim 1 ,
wherein presence/absence information related to presence or absence of the text data in each page is added to the electronic document as attribute information, and
wherein the display controller performs control so as to display whether the text data is included in each page of the electronic document by referring to the presence/absence information.
14 . A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
executing text selection processing for selecting text data from an electronic document; and
performing, when the text data is not included in the electronic document, control so as to display an indication that execution of the text selection processing is disabled before a user attempts to execute the text selection processing.
15 . A document processing apparatus, comprising:
execution means for executing text selection processing for selecting text data from an electronic document; and
display control means for performing, when the text data is not included in the electronic document, control so as to display an indication that execution of the text selection processing is disabled before a user attempts to execute the text selection processing.
