问题 I have texture with alpha. And I want to tint it with some color, so it will be colored depending on color alpha value, but overal opacity will be defined only by texture alpha. This is similar to multi-texturing but with color instead of second texture. How to do it? (Updated) I have tried to set up texture combiner. Color is tinted fine, but there is problem with alpha - it doesn't take value from texture (like mask). My code at this moment: glActiveTexture (GL_TEXTURE0); // do we need

问题 i want batch file to mask the input with * without extra file For example http://pastebin.com/2c4EtG4g this code is working successfully but it is very slow when i write the letter can any one give my code is fast and without an extra file ? or edit the code in the link to be fast ?? 回答1: Does this meet your "no extra file" criterion? It's a batch file that creates and deletes a tool to get the input, and so it is completely portable, and works in 64 bit machines too. Herbert Kleebauer wrote

问题 I have a task to complete in C#. I have a Subnet Mask: 255.255.128.0. I need to find the number of bits in the Subnet Mask, which would be, in this case, 17. However, I need to be able to do this in C# WITHOUT the use of the System.Net library (the system I am programming in does not have access to this library). It seems like the process should be something like: 1) Split the Subnet Mask into Octets. 2) Convert the Octets to be binary. 3) Count the number of Ones in each Octet. 4) Output the

问题 I've been looking for a simple way to invert a mask in flash. Its just amazing how it doesn't have this feature. I just really need to paint shape and whatever is below (in layers) wont show up. Any suggestions? 回答1: To create an inverted mask in code do the following private function createInvertedMask(mcToBeMasked:MovieClip):void { mcToBeMasked.blendMode = BlendMode.LAYER; var invertedMask:Sprite = new Sprite(); invertedMask.graphics.beginFill(0x0, 1); invertedMask.graphics.drawRect(640,

问题 I have a three-dimensional array (image) with shape (480, 640, 3) . Here, the 3 refers to BGR color code. I would like to place a mask over this image using the data from the array of the Red image. Depending on its value, certain pixels need to be masked. Creating the mask works fine. It behaves exactly as expected. In order to apply the mask to the original image, I first apply the mask to the Blue and Green image. All is still fine. Now I stack the three masked arrays, which returns an

问题 The effect that I am trying to achieve is having a circle of light in an area of darkness. The effect is similar to that in pokemon games, when you are in a dark cave and only have limited vision surrounding you. From what I have tried and read, I have been unable to create a mask over nodes in sprite kit that has alpha levels. The masks I manage to create all have a hard edge, and basically just crop. Reading on the apple developer page about the SKCropNode, which has the maskNode property,

问题 I have two scipy_sparse_csr_matrix 'a' and scipy_sparse_csr_matrix(boolean) 'mask', and I want to set elements of 'a' to zero where element of mask is True. for example >>>a <3x3 sparse matrix of type '<type 'numpy.int32'>' with 4 stored elements in Compressed Sparse Row format> >>>a.todense() matrix([[0, 0, 3], [0, 1, 5], [7, 0, 0]]) >>>mask <3x3 sparse matrix of type '<type 'numpy.bool_'>' with 4 stored elements in Compressed Sparse Row format> >>>mask.todense() matrix([[ True, False, True]

问题 How to apply loadMask to only one element, and not the whole browser width-height? default here, only one element is masked, and a messageBox is in center, inside this element and not the whole display... any ideas? EDIT: @Molecule , thanks, but this is when data is loading from some source, what i need is : { xtype:"button", text:"Alert", handler: function(){ Ext.Msg.show({ title:'Save Changes?', msg: 'You are closing ?', buttons: Ext.Msg.YES, setLoading: // here somehow only mask parent

问题 How can I detect the difference between 2 images, creating a mask of the area that's different in order to process the area that's common to both images (gaussian blur for example)? EDIT: I'm currently using this code to get the RGBA value of pixels: + (NSArray*)getRGBAsFromImage:(UIImage*)image atX:(int)xx andY:(int)yy count:(int)count { NSMutableArray *result = [NSMutableArray arrayWithCapacity:count]; // First get the image into your data buffer CGImageRef imageRef = [image CGImage];
