问题 I have the following code in my .htaccess RewriteRule ^([a-zA-Z0-9_-]+)/?$ index.php?mode=$1&%{QUERY_STRING}) It works great for one variable but I want to pass some additional variables and would like them to so up like the first one. So instead of having /about/?anotherVar=extra I have /about/extra. The additional variable would be on some pages not all I now have: #<IfModule mod_rewrite.c> # RewriteEngine on # RewriteCond %{REQUEST_FILENAME} !-f # RewriteCond %{REQUEST_FILENAME} !-d #<

问题 How can I create a PNG file if I have two separated JPG files with the image and the alpha channel? JPG Image + JPG Mask --> PNG with transparency I've tried WPF solutions: image.OpacityMask = new ImageBrush ( new BitmapImage ( uriMask ) ); and System.Drawing. Image bmpMask = Image.FromFile ( maskFilePath ); gfxNewImage.SetClip ( Graphics.FromImage (bmpMask) ); but I have problems with both (black background, or full black) Any idea or example? ThankYou 回答1: Ok Let's assume that you have a

问题 I have been using this $("#SomeId").mask("99"); jquery mask for text box where I want to enter only two digit numbers, but i do not know which mask to put in order to enable entering only one digit number and two digit.

问题 I have an image and I want to simply remove(or mask) parts of it with OpenCV. this is my original image : And I want to remove a circle on its center via this image mask : I use this command in my code which from the tutorials I read should work and black out a circle in the center of my original image : img = cv2.bitwise_not(imgOriginal,imgOriginal,mask=imgMask) but the result I get is the image below, in fact instead of removing the masked parts, it just inverts blacks and whites: I'll

问题 I found this line confusing? When configuring a mask, remember to set the size and position of the mask layer to ensure it is aligned properly with the layer it masks. What align means here? Does it means that you have to provide a mask that as a frame equal the bounds of the masked layer? Does it means that you can't be outside the visible part of the bounds of the masked layer? 来源： https://stackoverflow.com/questions/33278723/calayer-mask-property

问题 I want to apply a CIFilter to a CALayer except for an area which is an union of rectangles. I post my not working code, it does exactly the opposite, i.e. the filter is applied only in the rectangles and not outside! func refreshTheFrameWithEffect() { self.layer!.masksToBounds = true self.layerUsesCoreImageFilters = true self.layer!.needsDisplayOnBoundsChange = true let filter = CIFilter(name: "CICircleSplashDistortion") filter!.setDefaults() self.layer!.backgroundFilters = [filter!] var

问题 I have a binary mask which labeled the foreground of image. Many image processing algorithms such as histogram equalization or otsu method deal with the whole image. My question is how to apply those image processing algorithms so that they can ONLY process the region which my binary mask labeled? For example, I is the grayscale image and BW is the binary mask. The code below still process the whole image rather than the specific region labeled by the BW mask. level = graythresh(I.*BW); BW =

问题 To start, this project has been built using Swift. I want to create a custom progress indicator that "fills up" as the script runs. The script will call a JSON feed that is pulled from the remote server. To better visualize what I'm after, I made this: My guess would be to have two PNG images; one white and one red, and then simply do some masking based on the progress amount. Any thoughts on this? 回答1: Masking is probably overkill for this. Just redraw the image each time. When you do, you

问题 I am trying to mask input only with optional negative or positive integers. I tried using jQuery(function($){ $.mask.definitions['~']='[-]?'; $("#eyescript").mask("~?999999999"); }); but this is allowing any character at the first place. (Eg: f12, -12, +12, /12, etc..) I want the user to strictly use only '-' or any number in the first position. How can I do this? 回答1: Actually, I think I found the answer. Added one integer or negative sign as optional and reduced one 9 from the mask to
