问题 I have an online map that contains a ground-overlay image, and would like to make the image semi-transparent so that the base map will show through. Is it possible to add a transparency value to this overlay? http://www.tpwd.state.tx.us/fishboat/fish/recreational/lakes/ingulf1c.phtml Here's the code for the ground overlay: var imageBounds = new google.maps.LatLngBounds( new google.maps.LatLng(25.71438633861514, -98.33555959121725), new google.maps.LatLng(30.40813339247205, -93.57953893270167)

问题 I'm in need of some sample DICOM files that I can use to test out multiple overlays. I have looked everywhere, maybe i'm not searching for the right thing idk, but could anybody help me with this?? The real reason I want the DICOM files is to better understand the Overlays data structure hands on... I need to examine the files. Links to sites would be appreciated. 来源： https://stackoverflow.com/questions/4939364/free-dicom-files-with-multiple-overlays

问题 I am adding around 1000 MKPolygon s onto an MKMapView . After adding the overlays onto the MKMapView it works fine. However if I zoom in and zoom out quickly (occasionally letting go of the zoom so the mapView processes it's new visibleMapRect ) I find the app (sometimes) crashes with the following exception stack trace: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSSetM removeObject:]: object cannot be nil' *** First throw call stack: ( 0

问题 I have a DICOM image that I am reading using C# and converting it into a 16bit bitmap. The bitmap gets created but the image has DICOM overlays. I want to burn the overlay into the bitmap while creating the final dicom bitmap. I am unable to do that. Any help? One way would be to create a bitmap of overlay data and merge the 2 bitmaps but I can not get the overlay data as bitmap also. I have captured the binary overlay data but how do I burn into a bitmap? Thanks 回答1: There are two types of

问题 Hi what I have is a couple of Mat that I want to overlay (in a custom order). The Mat holdes some opencv polygons (which means a lot transparency). This Mat I need to overlay/merge. But not with the classical alpha blending more like with a 100% opacity but with transparency. This is a simple sample code of what I want to merge. Mat m1, m2; m1.create(Point{ 100,100 }, CV_8UC4); m2.create(Point{ 100,100 }, CV_8UC4); cv::polylines(m1, std::vector<Point>{ Point{ 2,20 },Point{ 20,40 } }, true,

问题 Long story short Please see the demo here. I have several div.story-in-myworks inside each div.story-in-myworks , there is a div.pageimage-div-overlay that controls the overlay over each div.story-in-myworks . Inside each div.pageimage-div-overlay there is a a.btn-storysetting responsible for hiding and showing a div.storysettings_talkbubble_left . both a.btn-storysetting and div.storysettings_talkbubble_left are child elements of div.pageimage-div-overlay . Here is a snippet: <div class="img

问题 I am having trouble with overlays. I have drawn a polygon overlay on the map, however, when I zoom in or out, the edges no longer align with where I want them to. How can I fix this? Here is what it looks like when I start the app (it covers the whole parking lot perfectly): Correct Here is what it looks like when I zoom out (edges no longer line up with parking lot. The overlay looks a bit bigger than the parking lot): Zoomed out Also, it doesn't align well when I zoom in. In this case the

问题 I've been experimenting today with text properties in Emacs. If I position the cursor on a line with some text on it and then execute the following code with M-: , the line is redisplayed in bold. (overlay-put (make-overlay (line-beginning-position) (line-end-position)) 'face 'bold) If, however, I wipe out the overlay with (remove-overlays) and execute the following code, nothing happens (except that the word "nil" appears in the minibuffer).
