Swift library to read Photoshop PSD files

PhotoshopReader

Swift library to read Photoshop PSD files.

Example Usage

Add the following line to your project's SwiftPM dependencies:

.package(url: "https://github.com/hughbe/PhotoshopReader", from: "1.0.0"),

import PhotoshopReader

let data = Data(contentsOfFile: "<path-to-file>.psdb")!
let document = try PhotoshopDocument(data: data)
print(document.header)
print(document.colorModeData)
for resource in document.imageResources.resources {
    let data = try ImageResourceBlockData(resource: resource)
    print("\(resource.id.hexString): \(resource.data.count) bytes")
}

if let layers = document.layerAndMaskInformation.layerInfo?.layers {
    for layer in layers {
        for additionalInformation in layer.additionalLayerInformation {
            let data = try AdditionalLayerInformationData(layer: additionalInformation)
            print("\(additionalInformation.key): \(additionalInformation.data.count) bytes")
        }
    }
}

photoshopreader's Issues

PackBits decompress is very slow

The decompress functions seems to be slow because it uses reserveCapacity() within a loop (decompressing a 2000x3000 pixels layer channel took minutes on my mbp16)

Just using append() should be faster (https://www.hackingwithswift.com/articles/128/array-performance-append-vs-reservecapacity), but I don't know if there are any downsides.

Get layer images from PSD.

How can I get images of all layers from PSD?

PhotoshopReader can't access font details like fontFamily & size

Please anyone help me on how to access text fonts, I've tried this but not getting !

let info = AdditionalLayerInformationData.typeToolInfo(try TypeToolInfo(dataStream: &dataStream1))

let info = try? TypeToolInfo(dataStream: &dataStream)

 print("info = ", info)

Inclusion of tests makes the package very heavy

hello
I am using SPM to access your framework in xCode. I regret that this package is soooo big (its one the heaviest I am using). IS there a way to avoid downloading all those test images?
