我不希望tinymce使用斑点来生成小图像，因为我正在将这些data:images转换为真实的图像，并且在得到真实图像后替换img src=""。我如何管理它以仅获得data:image图像？可能吗？我尝试过

automatic_uploads: false

但这改变不了什么。
下面是我的代码：

tinymce.init({
    selector: strSelector + "textarea:not(#strDescription)",
    paste_data_images: true,
    image_advtab: true,
    mode: "specific_textareas",
    editor_selector: "mceEditor",
    automatic_uploads: false,
    file_picker_callback: function(callback, value, meta) {
        if (meta.filetype == 'image') {
            $('#upload').trigger('click');
            $('#upload').on('change', function() {
                var file = this.files[0];
                var reader = new FileReader();
                reader.onload = function(e) {
                    callback(e.target.result, {
                        alt: ''
                    });
                };
                reader.readAsDataURL(file);
            });
        }
    },
    plugins: [
        "advlist autolink lists link image imagetools charmap preview anchor code",
        "searchreplace visualblocks code fullscreen",
        "insertdatetime table contextmenu paste imagetools"
    ],
    setup: function(editor) {
        editor.on('change', function() {
            editor.save();
        });
    }
});
