unity3d - Unity increases size of imported sprites -

Perhaps you are misleading the physical texture size of PNG, which is 37.2 KB as you specify, with the size of the texture in the memory.

It does not matter if your file is JPG, PNG, or psd, the size of the game memory will take you as much as you specify. If you specify the maximum quality, which is 32 bit RGB uncompressed then it is 800 x 294 x 4 bytes (32 bit) = 235 200 x 4 bytes = 940 800 bytes = ~ 0.9 MB If you want to use less memory, then you can reduce the quality to 16 beats (4 beats per channel), or you can compress in memory types, however, give this texture Need the power of dimensions, and square (on iOS) again In this case, you have 1024 x 1024 x 0.5 bytes (4 bit per pixel PVRTC4) - 524 288 bytes = ~ 0.5 MB

These compressed textures were kept compressed. GPU memory is available on PowerVR's GPUs and many others, using them, you will reduce your memory usage, and even rendering time - there is less data to process, they are not exactly as 32 btr RGBA , But compared to 16 BRT RGBA Often better - you should check sequences by themselves.

If you need some more detailed information about texture compression, take a look at it too.

To sum it, the shape displayed by Unity is the size of the texture in memory, whose source is nothing with the file type or size, only the important thing is that the import type (compression) and maximum size Limit.

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -

Image
I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

multithreading - PhantomJS-Node in a for Loop -

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu

I know that it can speak as a very famous topic, but something that helps me with it Not found This scenario is: I have my functions function, no matter what's inside, it's a generic function that may depend on other toolboxes.
