Installation Tutorial

1. npm install pgm-utils
2. yarn add pgm-utils

Usage Instructions

1. Parse PGM to ImageData

   <Upload
    customRequest={async (info: any) => {
        const { file: originFileObj } = info;
        if (originFileObj.name.endsWith('.pgm')) {
            const pgmImg: ImageData = await PGMUtils.PGMTool.getImageDataByPGMBlob(originFileObj);
        }
    }}
    >
        <Button type="primary">Upload and parse PGM file</Button>
    </Upload>

2. Generate PGM from ImageData

   const pgmBlob: Uint8Array = PGMUtils.PGMTool.getPGMByImageData(imageData);

3. Unzip and parse zip files with pgm, yaml, and json files

 <Upload
     customRequest={async (info: any) => {
     const { file: originFileObj } = info;
     if (info.file.name.endsWith('.zip')) {
         if (originFileObj) {
         PGMUtils.DeflateTool.inflatePKG(originFileObj).then((res) => {
             console.log('>>>>res:', res);
         });
         }
     }
     }}
 >
     <Button type="primary">Upload and parse compressed PGM file</Button>
 </Upload>

4. Compress files and return a file object. It supports direct export of ZIP format files, which can include JSON, PGM, and YAML file formats. File names can be customized.

   import PGMUtils from 'pgm-utils';
   
   const record: Record<string, any> = {};
   record['test.json'] = {
       name: 'test',
       ...
   }; 
   record['test.pgm'] = ImageData; 
   record['test.yaml'] = {
        name: 'test',
        origin: [0,0,0],
        ...
   }
   PGMUtils.DeflateTool.deflatePKG(record, 'compressed name');

5. Directly compress and obtain a File object of ZIP type

 const file = await PGMUtils.DeflateTool.getDeflatePKG(record, 'compressed name');

6. Compress and directly export the ZIP file

   PGMUtils.DeflateTool.exportDeflatePKG(record, 'compressed name');

7. Get the content of the uploaded YAML file

   <Upload
        customRequest={async (info: any) => {
            const { file: originFileObj } = info;
            if (originFileObj.name.endsWith('.yaml')) {
                const yamlInfo = await PGMUtils.YamlTool.getYamlInfoByBlob(originFileObj);
            }
        }}
    >
        <Button type="primary">Upload YAML file</Button>
    </Upload>

8. Convert string data into YAML file object data

const yamlInfo = PGMUtils.YamlTool.getYamlInfoByContent(yamlContent);

9. Convert YAML object data into string-type data

const yamlContent = PGMUtils.YamlTool.getContentByYamlInfo(yamlInfo);
