Medical electronic books often need to display slice images as content, but the slice information carried by digital slice images is complete, and the amount of data is Very large, it is impractical to load all the huge information of digital slice images into e-books.
- Traditional medical e-books only use slice images that carry partial slice information as their image content, and do not select or store complete digital slice images. In other words, the prior art e-book only intercepts the partial slice image for display, but the slice information thus carried is not able to completely display the slice organization, so a plurality of partial slice images are selected for display, that is, in a multi-image manner.
- the inventor thought that the digital slice image is capable of carrying complete slice information. If the electronic book can fully utilize the digital slice image, the complete presentation of the slice information by the electronic book should be realized.

Instructing the user to display an image in the display window of the image display area 102.
- a hardware input such as a mouse or a keyboard
- opening a specific icon or link on the user interface of the client 100 Instructing the user to display an image in the display window of the image display area 102.
- the manner of adjusting the display window of the image display area 102 can also be used (refer to the embodiment in detail), loading and carrying the display in the first request. Magnification and display location request.
- the display unit that selects the magnification information and the display magnification request carried in the first request has two cases (refer to Embodiment 3, Steps M201 to M203, Steps M301-M305): According to the display requirement After the display unit is selected, the image elements in the display unit are adjusted to the required magnification, for example, only two display units storing corresponding 10 times magnification and 15 times magnification image elements are included, then 14 are carried in the user request.
- the display of the magnification ratio requires that the display unit corresponding to the 15x magnification image element be used, and the display server 500 also adjusts the image element delivered to the client 100, and reduces it to 14 times the magnification and then transmits it.
- a display unit corresponding to a 10x magnification image element may be selected, but there may be a problem that the display image is distorted, so it is preferable to select a display unit corresponding to a high magnification.
- the display unit that selects the location information to match the display location request carried in the first request does not only select one display unit, because the location information given by the user often appears in the form of a point, the point selected by the user. , is the concept of coordinate points on the image.
- a single image element it is a display unit, such as a range of pixels (see the discussion part of the corresponding image element of Embodiment 1), and therefore, is based on whether the point information given by the user falls into the coordinate information of the display unit (also location information) Determined within the defined range; further, since the length and width of the display window are user-adjusted, the relative length plus the user-selected point defines the desired partial digital slice image; All points (concept of coordinate points) are selected, and at least one display unit corresponding to a certain magnification information of the above points is selected, and the sub-digital slice images formed by the image elements pointed by the display units are spliced to form a partial digital slice image of the display.
- the process may be similar to the above process. Of course, since the amount of text information is small, it may be directly used.
- the sexual request is loaded to the client 100 and displayed in the display window of the text display area 101.
- the display server 500 is set up because the digital slice image stores a large amount of data, and the number of display units is large.
- One-time loading and display to the client 100 is not conducive to data management, because some data is unnecessary for a specific user, User-specific issues, for a single user, the one-time loading and display of digital slice images will result in wasted data.
