zHDR

Import .hdr file in zig

For large files, you should prioritize loading the all file in memory and using zHDR.parseFromMemory has it is much faster than other options. zHDR.parseFromFile can take up to 2 minutes to parse a 8k image.

const allocator = some_allocator;

// For small file
var img = zHDR.parseFromFilePath(allocator, "./file.hdr");
defer zHDR.releaseImage(allocator, &img);

// For larger files
var file = try std.fs.cwd().openFile("./file.hdr", .{});
defer file.close();

const endPos = try file.getEndPos();
const content = try file.readToEndAlloc(allocator, endPos);
defer allocator.free(content);

var img = zHDR.parseFromMemory(allocator, content);
defer zHDR.releaseImage(allocator, &img);
