region

问题 I created my Bluemix account with "US SOUTH" as region. Later I realized that I belong to the UK-Europe region, and I can change to it once I'm logged in. However, every time when I come back and log on again I need to switch again to UK region, because I cannot make this region the default one for my account. The login process takes me to my account with "US South" selected by default. Can this be fixed? 回答1: You can use the following URL to login directly to Bluemix UK region: https:/

问题 I am working with a MKMapview and I am having a problem with the zoom level and the region span. It would seem when the MKMapView is refreshed it resets the region to the values that have been hardcoded when I initially installed them. I am keeping track of the user's location and with any changes in the location of the phone the map should update via the CLLocationManagerDelegate and the delegate method listed below. Currently I have this in the locationManager:didUpdateToLocation

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I'm trying to apply an algorithm only to a specific region of an image. I tried imfreehand , but not able, at least for me, to do that using this function. So, is there some way when running my code for the operations to be applied only to some specific region of an image in MATLAB ? Thanks. 回答1: Using a mask

问题 What is the fastest way of getting the area of any arbitrary Windows region? I know I can enumerate all points of bounding rectangle and call the PtInRegion() function but it seems not very fast. Maybe you know some faster way? 回答1: When you call GetRegionData, you'll get a list of non-overlapping rectangles that make up the region. Add up their areas, something like this: function GetRegionArea(rgn: HRgn): Cardinal; var x: DWord; Data: PRgnData; Header: PRgnDataHeader; Rects: PRect; Width,

问题 As part of a project I'm working on I have to store and restore magic wand regions from an image. To obtain the data for storage, I'm utilizing the GetRegionData method. As the specification specifies, this method: Returns a RegionData that represents the information that describes this Region. I store the byte[] kept in the RegionData.Data property in a base64 string, so I can retrieve the RegionData later through a somewhat unconventional method: // This "instantiates" a RegionData object

问题 When I open a code file in a new code window, I press Ctrl+M,O to collapse everything there. As far as I know this can be done by default, without need to press anything every time. I think I did it once, but can't remember where was this option located. 回答1: As a last resort if you can't get it to work with settings, you can also write a macro to do this. Check out this link for an example on this. Here is the main information from the link: You can open the Macro IDE by going to Tools-

问题 I have a Region, from which I am subtracting n number of Rectangles, now I need to get all the remaining space in terms of rectangles. Is there a way of doing it? Thanks 回答1: First you should realize that any set of rectangles you get may be an approximation if the region contains any curves. Second, try calling GetRegionScans with an indentity matrix. RectangleF[] rects = region.GetRegionScans(new Matrix()); 来源： https://stackoverflow.com/questions/16882292/read-regiondata-as-rectangles

问题 I have two region say rgn1 and rgn2 . I wanted to combine both of them using CombineRgn function. So I write - if CombineRgn(rgnMain,rgn1,rgn2,RGN_OR) = error then ShowMessage('error'); Its giving return value as ERROR. I have tested that rgn1 and rgn2 are correct region. Thank You. 回答1: Have you also initialised rgnMain ? Somewhat counterintuitively (but as described in the documentation for CombineRgn()) the destination/output region must exist in order to receive the required combination

问题 I want to detect mouse click on my custom created region. 1) I ve tried this code with rectangle and it worked, but with string it doesnt GraphicsPath gp = new GraphicsPath(); Region reg = new Region(); private void Form1_Load(object sender, EventArgs e) { gp.AddString("TEXT", new FontFamily("Arial"),0, 20.0f, new Point(300, 10), StringFormat.GenericDefault); gp.Widen(Pens.AliceBlue); reg = new Region(gp); } and here is the part2 private void panel1_MouseDown(object sender, MouseEventArgs e)
