Abstract
Conventionally, in displaying a document on a display, the document is displayed on the display after an image of the document is drawn off-screen once. Thus, it may take long until the image of the document can be checked when it is drawn for the first time. In an image processing apparatus of this invention, every time a predetermined number of drawing elements among drawing elements included in document data are developed off-screen, it is checked whether or not the developed off-screen drawing elements satisfy intermediate drawing conditions and, when it is determined that the intermediate drawing conditions are satisfied, the developed off-screen drawing elements are drawn on the display.
Claims13
An image processing apparatus comprising:
- off-screen development means for developing drawing elements included in document data off-screen;
- display drawing means for performing control to draw a developed off-screen drawing element on a display;
- and
- intermediate drawing check means for, every time a predetermined number of drawing elements among the drawing elements are developed by the off-screen development means, checking whether or not the developed off-screen drawing elements satisfy predetermined intermediate drawing conditions and, when it is determined that the predetermined intermediate drawing conditions are satisfied, controlling the display drawing means to draw the developed off-screen drawing elements on the display.
An image processing method comprising:
- an off-screen development step of developing drawing elements included in a document data off-screen a program code for causing the computer to execute;
- a display drawing step of performing control to draw a developed off-screen drawing element on a display;
- and
- an intermediate drawing check step of, every time a predetermined number of drawing elements among the drawing elements are developed by the off-screen development step, checking whether or not the developed off-screen drawing elements satisfy predetermined intermediate drawing conditions and, when it is determined that the predetermined intermediate drawing conditions are satisfied, controlling the display drawing step to draw the developed off-screen drawing elements on the display.
A computer program executable by a computer for processing an image in an information processing apparatus, comprising a program code causing the computer to execute:
- an off-screen development step of developing drawing elements included in document data off-screen;
- a display drawing step of performing control to draw the developed off-screen drawing element on a display;
- and
- an intermediate drawing check step of, every time a predetermined number of drawing elements among the drawing elements are developed by the off-screen development step, checking whether or not the developed off-screen drawing elements satisfy predetermined intermediate drawing conditions and, when it is determined that the predetermined intermediate drawing conditions are satisfied, controlling the display drawing step to draw the developed off-screen drawing elements on the display.
A storage medium which stores a computer program executable by a computer for processing an image in an image processing apparatus, the computer program comprising a program code for causing the computer to execute:
- an off-screen development step of developing drawing elements included in document data off-screen;
- a display drawing step of performing control to draw the developed off-screen drawing element on a display;
- and
- an intermediate drawing check step of, every time a predetermined number of drawing elements among the drawing elements are developed by the off-screen development step, checking whether or not the developed off-screen drawing elements satisfy predetermined intermediate drawing conditions and, when it is determined that the predetermined intermediate drawing conditions are satisfied, controlling the display drawing step to draw the developed off-screen drawing elements on the display.
