Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a layout editing method and system for performing layout of images when creating printed materials such as leaflets and catalogs using a computer and its peripheral devices (display device etc.), In particular, the present invention relates to a layout editing method and a layout editing system capable of improving the screen display speed to improve the efficiency of the image allocating work and eliminating the trimming / magnification error between the screen and the output material.

[0002]

2. Description of the Related Art Conventionally, for example, when a printed matter such as a leaflet or a catalog is produced, its layout design or layout simulation is performed at a stage before a plate making process, and a peripheral device such as a computer and a display device (so-called computer workstation) is used. It is known to be used.

In this case, the operator displays a screen corresponding to the printed matter on the screen of the display device, and an image,
Work such as arrangement of letters and the like, correction of size and position, etc. is performed to lay out the elements printed on the printed matter.

On the other hand, recently, a character / image allocating device using a computer such as DTP has been proposed. When allocating images, this character / image allocating device arranges low-resolution gradation data (rough data) instead of printing images with large data sizes and trimming
The magnification is set.

After that, at the time of outputting, a method of replacing with high resolution gradation data (image data for printing) is adopted so as to cover the speed reduction at the time of layout editing.

[0006] Here, as a method of performing layout work with low resolution images and replacing with high resolution image data at the time of output, for example, APR (Automatic)
Picture Replacement), OPI
There is a system called (Open Prepress Interface).

However, in such a system, since the layout work is performed by using the low-resolution image in which the data size is reduced, the same size as the entire page size or a large number of points are handled. In this case, it takes time to draw the screen and the burden of the layout work is increased. Further, since it is difficult to see details in a low-resolution image, a trimming / magnification error occurs between the screen and the output material.

[0008]

As described above, in the conventional character / image allocating device, not only the burden of the allocating work is heavy, but also the trimming / magnification error occurs between the screen and the output material. was there.

The present invention has been made to solve the above-mentioned problems, and improves the screen display speed to improve the efficiency of the image allocating work, and at the same time, to perform trimming and trimming between the screen and the output material. An object of the present invention is to provide a layout editing method and a layout editing system capable of eliminating a magnification error.

[0010]

In order to achieve the above object, first, in the invention corresponding to claim 1, the layout of an image when a printed matter such as a leaflet or a catalog is created,
In a layout editing method using a peripheral device such as a computer and a display device, when laying out image data on the display device, high resolution image data to be laid out is converted into layout vector data, As the layout vector data is allocated, the magnification, rotation, and trimming settings are made and arranged.When outputting the data, the layout vector data arranged above is replaced with high-resolution image data and output. There is.

Further, in the invention according to claim 2, in a layout editing system in which a layout of an image when creating a printed matter such as a leaflet or a catalog is performed by using a peripheral device such as a computer and a display device, The image processing means for performing the predetermined image processing to convert the high resolution image data into layout vector data and the layout vector data obtained by the image processing means are allocated, and the magnification, rotation and trimming settings are performed. An image allocating means for obtaining the layout data to be executed, and an output means for replacing the layout data obtained and transferred by the image allocating means with high-resolution image data stored in advance and outputting the output data when an output request is made. Consists of

Here, it is preferable that the image processing means converts the high-resolution image data to be laid out into a vector image for layout by subjecting a monochrome image to conversion / edge extraction processing.

[0013]

Therefore, in the layout editing method and the layout editing system of the present invention, when laying out the image data on the display device, the high resolution image data to be laid out is converted into layout vector data, The layout vector data is allocated as a hit, the magnification, rotation, and trimming settings are performed and arranged. When the data is output, the arranged layout vector data is replaced with high-resolution image data and output.

In this case, since the image data is laid out by using the vector data for layout, the time required for screen drawing is short even when handling the same size as the entire page size or a large number of points. It is possible to improve the screen display speed on the display device and improve the efficiency of the image allocation work.

Further, since the layout of the image data is performed by using the vector data for layout, the details are not difficult to see, and a portion between the screen and the output product which is generated when the above-mentioned low resolution image is allocated. Trimming / magnification error can be eliminated.
