Definitions

  • the invention relates to a method for superimposing partial images for creating overall images, in particular illustrated texts, in which partial image information stored at different locations is combined to form overall image information in accordance with a previously defined instruction.
  • Devices which carry out the superimposition of differently coded images, in particular images in dot-matrix representation, of vectorially coded drawings and of character-coded text, and are often connected to devices for output on screen or paper, in particular with graphic screens and matrix Plotter.
  • printer plotters If such plotters are combined with a device for overlaying dot screen images and characters, they are referred to as printer plotters.
  • this compilation takes the form of a link or in such a way that a certain part of one text is replaced by another, not in the form of an overlay.
  • this method is limited to patterns consisting of text characters.
  • the invention has for its object a. From a workstation controlled overlay of images that are partially created or entered at the workplace, some are stored at any, possibly different locations, for output, possibly after buffering, at a suitable two dimensional medium, such as a screen or on paper.
  • image is understood to mean a two-dimensional pattern which is defined by the assignment of brightness and color to a pair of coordinates.
  • characters and line drawings are also pictures.
  • the invention offers the advantage that the method can be implemented at suitable workplaces in a workstation network.
  • the images or partial images required for an overlay file can advantageously be stored at different locations.
  • the output of an overlay image can also be requested from a different workstation than the one who created the overlay file required for this.
  • Ü file Facilities that are required to create the overlay file (hereinafter referred to as the Ü file), for transferring the Ü file and the images, for overlaying the images and for outputting the overlaid images after overlaying are known, as are (for one other purpose) the connection of such facilities.
  • FIG. 1 shows an exemplary embodiment of a device for creating a Ü file, which according to the invention consists of an additional device A for creating a text file with keyboard T and an image capture device B which is connected to a suitable interface of the additional device A.
  • This interface is characterized by the entirety of the two interfaces 2 and 3 are shown, with about. 2 the image data acquired by B and transmitted via 3 control signals.
  • B consists of a camera K and an interface IF.
  • the additional device A contains a switching device U, by means of which the input of character-by-character and possibly differently coded information between the keyboard and the interface 2 can be switched. This switchover can be initiated by the image capture device via the interface 3.
  • FIG. 2 shows an exemplary embodiment of an arrangement with several devices according to FIG. 1.
  • This arrangement consists of devices for creating a transmission file, devices for overlaying images, devices for outputting images, and storage for Archiving of images and other data, facilities for the transmission of Ü-files and images as well as any other facilities that enable or facilitate the additional use of the facilities mentioned for other purposes.
  • All types of storage for example disk, tape or microfilm files of varying sizes, are suitable for archiving image and other files, with some files preferably being used for image archiving.
  • the 'transmission of images and Ü files can be done in a known manner by dedicated or selected lines or materially by transfer of the storage medium (eg tape or plate or printed paper).
  • Printers with sufficient resolution are suitable for image output solution, in particular vector and matrix plotters, facsimile output devices or facsimile machines, if output on paper is desired.
  • There are facilities available for output on the screen such as those used at graphics workstations and microfilm archives.
  • the method according to the invention makes it possible to output images consisting of a plurality of superimposed images, which may be clear and error-protected, using known devices from any workstation of a first workstation network at any number of image display devices. with different coding - either transmitted from the workstation or archived at different storage locations.
  • the overlaid images are called "partial images" in the following.
  • An image is understood here to mean a two-dimensional pattern which is defined by an assignment, with a pair of coordinates being a sequence of real parameters. is assigned meters, which mean, for example, brightness, hue, color saturation. In this sense, representations of letters and line drawings are also pictures. It is contemplated that an image is defined over a discrete coordinate grid, that is, a line or a dot grid.
  • the method consists in that the user of a work station creates a file at this work station - hereinafter referred to as an overlay file or briefly as a transfer file - which contains each of the partial images and / or to be overlaid contains an identification assigned to it, as well as an instruction for overlaying these sub-images, hereinafter referred to as a transfer instruction, and that this transfer file, if necessary, is forwarded to a device which carries out this overlay (transfer device), whereby it contains those Partial images, or at least their image elements required for the overlay, which are not contained in the Ü-file, are taken from the storage locations which are specified directly or indirectly in the respective identifications.
  • an overlay file or briefly as a transfer file - which contains each of the partial images and / or to be overlaid contains an identification assigned to it, as well as an instruction for overlaying these sub-images, hereinafter referred to as a transfer instruction, and that this transfer file, if necessary, is forwarded to a device which carries out this
  • Indirect information is understood here to mean that the storage locations can be determined from the identifications by the transmission facility.
  • the identification is the name of a file in which the relevant drawing file is archived.
  • Such a file is called "image file” in the following.
  • the coding of a transmission file is in itself arbitrary insofar as it can be interpreted by the transmission device to which it is sent. Proposals for advantageous coding of the Ü file are given below.
  • a further development of the method according to the invention consists in the fact that in a transfer file instead of a part The identification of another (second) transfer file is specified, and that the transfer device takes the second transfer file from the storage locations specified there and produces the drawing file by executing the transfer instruction contained therein.
  • third and higher transfer files can be used in the process.
  • This further training brings the advantage that a user of the Ü device only needs to transfer the identification of an image without having to know whether this image is available as an image file or in the form of an Ü file. This difference cannot be determined from the output image.
  • Ü file which contains the identification of the microfilm image and, as partial images, the additional entries or corresponding identifications.
  • the microfilm image is in an archive that allows the electronic transmission of the image to the transmission facility.
  • a key word is included that identifies the file as a file.
  • each user is assigned an access identification, for example ABC17, which can be classified if necessary, for example by the first two characters of the identification, ie ABC 17 belongs to class AB.
  • the procedure is that After the creation of a Ü file, all blocking notes that are assigned to external identifications are read and checked to see whether the access identification of the user or their class is contained therein and - if this is not the case - the respective blocking note by the access identification of the user or whose class is added.
  • the addition takes place in the form and according to the procedure intended for the extension of files of this type. It can be done with lower priority, and therefore at less expensive times.
  • Ü file can be created at any time after the Ü file has been created, if necessary for the first time immediately and automatically after creation.
  • the user can, but does not have to, be the same as the creator of the file.
  • the addition can be made by any number of authorized users, whereby known measures (password, ID card) can be used to regulate the access authorization.
  • the addition of the blocking note contains the date of the addition and, if applicable, a qualification that contains a measure desired by the user, e.g. Notification or creation of a copy of the original condition, specified.
  • the measures that are taken in the event of an intended change to an image or transfer file to which a blocking note is assigned can be agreed in the blocking note.
  • the following describes a facility that facilitates the creation of Ü-files that contain images. It consists of an addition to a facility suitable for creating text files.
  • Such a facility is e.g. a. Text workstation or a teleprinter that is connected to a computer system via an arbitrarily long connection.
  • the file is transferred to the computer system in characters or blocks during the creation, with the decision to archive only at the end of the creation. Until then, the created part of the file will be saved in a location that is insignificant for the user. Such a file is called a "virtual file”. If archiving is dispensed with, transmission to any partner and output is nonetheless possible.
  • At least (b) is fixed in a way that the existing * input and transmission devices can be largely unchanged that an image capture device, e.g. a camera or a facsimile scanner, is connected to this interface via a recoding device, which adapts the output signal of the image capture device to a suitable interface of the text creation device.
  • an image capture device e.g. a camera or a facsimile scanner
  • this interface in the input device is connected to the image capture device in the output direction with the partner.
  • the device also includes a switching device, see Fig. 1, which is between the input from the image capture device and the other input devices, e.g. the keyboard.
  • a switching device see Fig. 1
  • an existing switchover device can be used, which is provided for switching the interface on or off, to which the image capture device is connected.
  • the existing hardware and software facilities can be used to switch over.
  • Known image capture devices e.g. Remote copiers send a signal after detection, which can be used to control a switching device.
  • FIG. 3 An example of the coding of an image by printable characters is given in FIG. 3. It represents the image to be encoded - a dot pattern - and gives a sequence of characters arranged in 13 lines, i.e. the coding of this picture again.
  • the sign "#" means the beginning or end of the picture.
  • the individual lines each represent a row of dots, the characters 0, 1, 2, 3, 4th, 5, 6, 7, 8, 9, A, B, C, D, E, F in the known hexadecimal representation of the dot sequences "----", "--- •", "- • -” to "••••” are assigned.
  • Spaces within a row of dots mean missing dots.
  • the end of a row of dots is coded by the characters "carriage return" and / or "line feed", which are contained in the Ü- or image file.
  • FIG. 4 shows a further picture, namely a character with the associated coding.
  • the sign “#” means the beginning or end of the picture
  • the character strings "S12" and “TA” mean that the signs " T “and” A "are to be replaced by dot patterns which are assigned to the respective characters in a data field archived under the identification" S12 ".
  • these dot patterns consist of 8 rows of dots, each with 7 (missing or existing) dots.
  • FIGS. 3 and 4 show different superimpositions of the images of FIGS. 3 and 4. They differ in the relative position of the two partial images, in the relative magnification of the two partial images and in the way in which the two partial images are linked.
  • each image can be viewed as a superimposition of several partial images, the image elements of which can be described as a function of the image elements of the partial images.
  • FIG. 5 and 6 show two examples of an overlay of images.
  • FIG. 5 was created by superimposing the image of FIG. 4, which had been enlarged twice, with the image (arrow) of FIG. 3, which had been reduced to half.
  • FIG. 6 was created by superimposing the image from FIG. 3 with the image (arrow) from FIG. 4 reduced to half.
  • the overlay is erased, i.e. the pixels of the first partial image are replaced by the pixels of the second reduced partial image in its (rectangularly delimited) area.
  • FIG. 7 and 8 show the partial images B1 and B2 reduced by a factor of 4, the respective image boundaries (corresponding to a DIN A4 area) being drawn in (arrows).
  • Fig. 9 shows, in the same reduction, the overlay image.
