binary_data:binary-linking,binary_data,binary-linking,Linking to binary downloads,"The  .blob  output format is used to return binary data. It requires a  _blob_column=  query string argument specifying which BLOB column should be downloaded, for example: 
             https://latest.datasette.io/fixtures/binary_data/1.blob?_blob_column=data 
             This output format can also be used to return binary data from an arbitrary SQL query. Since such queries do not specify an exact row, an additional  ?_blob_hash=  parameter can be used to specify the SHA-256 hash of the value that is being linked to. 
             Consider the query  select data from binary_data  -  demonstrated here . 
             That page links to the binary value downloads. Those links look like this:

             These  .blob  links are also returned in the  .csv  exports Datasette provides for binary tables and queries, since the CSV format does not have a mechanism for representing binary data.","[""Binary data""]","[{""href"": ""https://latest.datasette.io/fixtures/binary_data/1.blob?_blob_column=data"", ""label"": ""https://latest.datasette.io/fixtures/binary_data/1.blob?_blob_column=data""}, {""href"": ""https://latest.datasette.io/fixtures?sql=select+data+from+binary_data"", ""label"": ""demonstrated here""}, {""href"": ""https://latest.datasette.io/fixtures.blob?sql=select+data+from+binary_data&_blob_column=data&_blob_hash=f3088978da8f9aea479ffc7f631370b968d2e855eeb172bea7f6c7a04262bb6d"", ""label"": ""https://latest.datasette.io/fixtures.blob?sql=select+data+from+binary_data&_blob_column=data&_blob_hash=f3088978da8f9aea479ffc7f631370b968d2e855eeb172bea7f6c7a04262bb6d""}]"

                     datasette-render-binary  modifies Datasette's default interface to show an automatic guess at what type of binary data is being stored, along with a visual representation of the binary value that displays ASCII strings directly in the interface. 
                 
                 
                     datasette-render-images  detects common image formats and renders them as images directly in the Datasette interface. 
                 
                 
                     datasette-media  allows Datasette interfaces to be configured to serve binary files from configured SQL queries, and includes the ability to resize images directly before serving them.","[""Binary data""]","[{""href"": ""https://github.com/simonw/datasette-render-binary"", ""label"": ""datasette-render-binary""}, {""href"": ""https://github.com/simonw/datasette-render-images"", ""label"": ""datasette-render-images""}, {""href"": ""https://github.com/simonw/datasette-media"", ""label"": ""datasette-media""}]"
