颤振中的图像融合

Question

是否有将多个图像合并到单个图像的方法。我看过merge_image库，但没有用。有人能帮上忙吗。我所拥有的只是图像文件的列表，我需要将其合并为单个文件。

Answer 1

您可以使用编辑器

  final slideLength = 180.0;
final option = ImageMergeOption(
  canvasSize: Size(slideLength * count, slideLength * count),
  format: OutputFormat.png(),
);

final memory = await loadFromAsset(R.ASSETS_ICON_PNG);
for (var i = 0; i < count; i++) {
  option.addImage(
    MergeImageConfig(
      image: MemoryImageSource(memory),
      position: ImagePosition(
        Offset(slideLength * i, slideLength * i),
        Size.square(slideLength),
      ),
    ),
  );
}
for (var i = 0; i < count; i++) {
  option.addImage(
    MergeImageConfig(
      image: MemoryImageSource(memory),
      position: ImagePosition(
        Offset(
            slideLength * count - slideLength * (i + 1), slideLength * i),
        Size.square(slideLength),
      ),
    ),
  );
}

final result = await ImageMerger.mergeToMemory(option: option);
provider = MemoryImage(result);
setState(() {});
