Upload any JPG/PNG image. 30 | 2. If the Number of Channels is missing, it will as for it. 31 | 3. Click the generate button. 32 | 4. The files will be automatically downloaded when the generation finishes. 33 | 34 | Advanced options coming soon. 35 | 36 | ## Node version (preferred version) 37 | 38 | ### How to use it 39 | 40 | 1. Clone this repository. 41 | 42 | 2. Install all dependencies. 43 | 44 | ` npm install ` 45 | 46 | 47 | 3. Put the image you want inside the app folder. You can just paste it or you can create a folder. e.g 48 | 49 | - markerCreatorAppFolder 50 | - app.js 51 | - NftMarkerCreator.min.js 52 | - IMAGE.PNG 53 | - ... 54 | 55 | or 56 | 57 | - markerCreatorAppFolder 58 | - app.js 59 | - NftMarkerCreator.min.js 60 | - FOLDER/IMAGE.PNG 61 | - ... 62 | 63 | 4. Run it 64 | 65 | ` node app.js -i ` 66 | 67 | 5. The prompt may ask you to insert information abou the image (width in px, height in px, DPI). It's strongly suggested to insert them. 68 | 69 | 6. In the end of the process an "output" folder will be created (if it does not exist) with the image-descriptors files. 70 | 71 | You can use additional flags with the run command. 72 | 73 | e.g node app.js -i image.png -level=4 -min_thresh=8 74 | 75 | -level=n 76 | (n is an integer in range 0 (few) to 4 (many). Default 2.' 77 | -sd_thresh= 78 | -max_thresh= 79 | -min_thresh= 80 | -leveli=n 81 | (n is an integer in range 0 (few) to 3 (many). Default 1.' 82 | -feature_density= 83 | -dpi=f: Override embedded JPEG DPI value. 84 | -max_dpi= 85 | -min_dpi= 86 | -background 87 | Run in background, i.e. as daemon detached from controlling terminal. (macOS and Linux only.) 88 | -log= 89 | -loglevel=x 90 | x is one of: DEBUG, INFO, WARN, ERROR. Default is INFO. 91 | -exitcode= 92 | --help -h -? Display this help 93 | 94 | 95 | 5. The generated files will be on the "output" folder. 96 | 97 | ------ 98 | #### If you want to generate you own NftMarkerCreator.min.js use the dev branch. 99 | 100 | 101 | "Icon made by Freepik from www.flaticon.com" 102 | -------------------------------------------------------------------------------- /docs/style.css: -------------------------------------------------------------------------------- 1 | body { 2 | background-color: #eee;
