    Style Transfer

    Function Introduction

    SuperMap iDesktop introduces the ability to change your map styles based on the style image you specify. Besides, you can adjust the hue, brightness, contrast, and saturation of your map.

    Application Scenarios

    • If you have had a map, you want to use it not only in one occasion. You can change its colors to use it in different situations. Such as your map uses warm colors when you need a map using cool colors, you can use the feature to change it conveniently and easily.
    • One map can has a lot of styles at the same time like subtle grey style, ancient building style, oil painting style, and so on.

    Highlighted Features

    • The application provides multiple style images. You are allowed to specify your own style pictures.
    • Style Transfer Settings : when extracting colors from a style image, you can set its compression mode and the color count.
    • Adjust colors : you can adjust hue, brightness, contrast, saturation, soften, and sharpen of layers (text, line, region). Besides, iDesktop supports other color settings like grey, black and white, and so on.
    • Undo/Redo : the Undo feature (or Ctrl Z) can undo the last operation. The Redo feature (or Ctrl Y) supports redoing the operation you have undone.

    Operating Instructions

    Multiple groups of style images are predefined including dark styles, colorful styles. Importing your own images also is allowed.

    1. Open your map.
    2. Using style image : click the AI Mapping tab> Style Transfer Gallery. Select the style image you want. iDesktop will display your map with the new style instantly.
    3. Using own image : click AI Mapping tab> Style Transfer Gallery > Custom to upload your own style image.
    4. In the style image preview window click Select button to change the style image.

    Transfer Settings

    You can specify the compression mode and the number of colors that will be extracted from your style image to make an improvement in image processing.

    1. Click AI Mapping tab > Style Transfer Gallery > Transfer Settings to open the Style Transfer Settings dialog box.
    2. Compression Mode : Four compression modes are provided aiming to enhance the performance of image processing.
    3. None : iDesktop won’t compress the style image.
    4. Antialias : The feature uses convolutions for resampling an image. The feature provides the best results among other algorithms but has low performance. The algorithm is set to default because of its high-quality results.
    5. Nearest Neighbour : The feature uses K nearest neighbor which is a supervised classification (or regression) algorithm that in order to determine the classification of a point, combines the classification of the K nearest points. The quality is lower than other available algorithms. However, it has the best performance.
    6. Linear Interpolation : The feature uses simple linear interpolation to resample an image. The output quality is less than Cubic spline interpolation but performance is better.
    7. Cubic Spline Interpolation : The feature uses cubic interpolation to resample an image. The output quality is less than Antialias but performance is better, because it uses internal supersampling rather than convolutions.
    8. Colors Count : The number of colors to be extracted from the style image. Default color number ranges from 50 to 200. You can set a proper number.

    Adjust Colors

    Adjust colors of the resulting text, lines and polygons by setting their brightness, contrast, and saturation to get a better effect. Besides, you can set a gray, black and white, or colorful map.
