尝试从WinForms应用程序打印时遇到2个问题.无论我尝试什么,第一个是非常糟糕的质量.第二个是我左上角有一个很大的页边距,而winform正在切割.有任何想法吗？这是我的代码:
Bitmap MemoryImage;
public void GetPrintArea(Panel pnl)
{
MemoryImage = new Bitmap(pnl.Width, pnl.Height);
Rectangle rect = new Rectangle(0, 0, pnl.Width, pnl.Height);
pnl.DrawToBitmap(MemoryImage, new Rectangle(0, 0, pnl.Width, pnl.Height));
}
protected override void OnPaint(PaintEventArgs e)
{
if (MemoryImage != null)
{
e.Graphics.DrawImage(MemoryImage, 0, 0);
base.OnPaint(e);
}
}
void printdoc1_PrintPage(object sender, PrintPageEventArgs e)
{
e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
e.Graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBilinear;
e.Graphics.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighQuality;
Rectangle pagearea = e.PageBounds;
e.Graphics.DrawImage(MemoryImage, (pagearea.Width / 2) - (this.panel1.Width / 2), this.panel1.Location.Y);
}
public void Print(Panel pnl)
{
panel1 …我想用Nopcommerce网站上的产品列表创建XML.因为图像是二进制的,我无法找到一种方法只获取图像的名称(我只需要图像名称不在图像上显示)任何想法？我丢失的代码在/ images/thumbs /的行中
topsystemDataClassesDataContext db = new topsystemDataClassesDataContext();
XmlTextWriter writer = new XmlTextWriter(path + "/Products_" + catid + ".xml", System.Text.Encoding.UTF8);
writer.WriteStartDocument(true);
writer.Formatting = Formatting.Indented;
writer.Indentation = 2;
writer.WriteStartElement("store");
//CREATE-SCREENS
var allProducts = (from p in db.Product_Category_Mappings
where p.CategoryId == catid
join s in db.Products
on p.ProductId equals s.Id
join im in db.Product_Picture_Mappings
on p.ProductId equals im.ProductId
join imag in db.Pictures
on im.PictureId equals imag.Id
select new
{
s.Name,
s.Id,
s.Price,
s.ShortDescription,
s.BackorderModeId,
im.PictureId,
imag.PictureBinary
}).ToList();
foreach (var item in allProducts) …我正在尝试一个月来制作简单的相机捕捉没有成功.我正在开发的这个应用程序几个月前工作很好,但因为我更新Android到版本7该应用程序停止正常工作.我想点击一个按钮,在捕获后激活相机(内置非api)以在imageview中显示图像(高质量)并将图像保存到图片文件夹.之后将图像发送到服务器.在我的应用程序的现有版本中,我捕获图像,在imageview中显示保存的图像并通过json发送到服务器.现在活动结果为空,imageview为空:-(请帮助
旧代码很有效
public void onClick(View v) {
switch (v.getId()) {
case R.id.cancel_btn:
finish();
break;
case R.id.camera_btn:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION, ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
break;
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Uri u = data.getData();
Log.d("u", String.valueOf(u));
theImageUriStr = String.valueOf(u);
Log.d("theImageUriStr", String.valueOf(theImageUriStr));
mImageView = (ImageView) findViewById(R.id.mImageView);
ALBUM_ART_URI = Uri.parse(String.valueOf(theImageUriStr));
Picasso.with(AddNewDish.this).load(ALBUM_ART_URI).into(mImageView);
}
else{
Log.d("mmmm", String.valueOf(resultCode));
}
}
我从Log.du和theImageUriStr获得的结果为null
我是ac#programmer,我正在尝试使用Swift 2构建本机应用程序.
public class ApiRoadsInfo
{
public string road_id { get; set; }
public List<RoadInfo> road_info { get; set; }
public List<Comment> comments { get; set; }
}
我的问题是:如何List<>在Swift 2中创建类似C#的？
struct....{
var road_id:String
???????? how?
