alchemy sampler

In opengl3.3, a sampler object is added first. Remember that when we used to use OpenGL, sometimes the same texture data is required, but the filter mode is different, however, since Multiple Attribute Sets cannot share the same texture object, therefore, it is very clumsy and wasteful to create two different texture objects (of course to share multiple texture objects with the same Pixel Buffer. The newly added samplerger object makes this work easy

This tutorial introduces a new method for color-offset image repair. Overall idea: 1, first sample color value: Using the Sampler tool in the picture to select a high light point and a dark point sampling color; 2, adjust the value: The high light and darkened the R value for reference, the value of the g,b are adjusted to the same value as R, 3, and finally find the middle of the value, the same method adjustment can be.

The big grab kits, such as Chrome's own developer tools, Firebug, and Fiddler, will display JSON data in a tree-like structure, very friendly and intuitive.(3) Multipart/form-dataThis method is commonly used to upload files.(4) Text/xmlXML is generally not used as a remote invocation specification for encoding.Four, JMeter interface application(1) content-type=application/x-www-form-urlencoded + Parameters(2) content-type=application/x-www-form-urlencoded + Body Data(2) Content-type=applicatio

1: Image sample collector, the English name is called Image Sampler, in fact, the whole picture is decomposed into a sample, and then a total of 4 ways: fixed, adaptive, adaptive subdivision, progressive The general use of self-adaptation is good. There is also a subdivision of how many samples a pixel is subdivided into. Of course, the larger the subdivision, the clearer the more. 2: Monte Carlo, mainly used to calculate a point above such as lig

Problem Description: JMeter to use a third-party developed package, in all jar packages under the JMeter Lib/ext, the interface of the sampler can not see the corresponding menu items, suspect loading reason: jdk inconsistent, jar package version is higher than JMeter Workaround: Resolve the use of the jar package, tearful the compiled JDK version, and compare the version, using a JDK version higher than the jar used to boot JMeter Modify the Jmeter.b

1.1.1 Sampling DeviceIn the 8 class of executable components, the sampler is a typical component that does not interact with other components, and the logic controller refers to the sampler for its child nodes, while the other components (configuration elements, timers, assertions, listeners) need to interact with elements such as samplers.The JMeter has two classes of controllers, samplers (

. Later, after colleagues to wake up, the last BeanShell Sampler did not knot, Balabala said the use of methods, finally understand the smell. Studied for half a day, and finally solved the problem satisfactorily. Now record it to save the dementia. Don't say much nonsense, open up.

begins, JMeter will wait as necessary until the start time is reached. 　　 At the end of each loop, JMeter checks to see if the end time has been reached and, if so, stops running, or the test continues until the iteration limit is reached. 3, the controller (controllers) JMeter has two kinds of controllers: Sampler and logic controller. 　　The processing of these drive tests. The sampler tells JMeter to sen

One, script recording (Jmeter): Jmeter script (. jmx) is in XML format, tree structure, composed of components, using "sampler" to generate the request. Add "HTTP Proxy Server" port to "Workbench": Proxy server port, default 8080, can modify itself, but do not apply port conflict with it destination controller: the location where the recorded script is stored, the selectable items are grouped into the thread groups in the test plan: groups the request

Previous blogs have introduced the scope of components in JMeter, where the scope of the logical controller (logic Controllers) is only valid for sampler of its child nodes, and the logical controller's role is to control the order in which the samplers are executed.The JMeter provides 17 logic controllers, each of which can be divided into 2 types of use:①. Control the sequence of logical execution of the nodes during the execution of the test plan,

First, jmeter important components:1) Configure Element---config element:Used to initialize default values and variables so that subsequent samplers can be used. Configuring the initial stage processing of a component's scope, the configuration component is valid only for the branch of the test tree in which it resides, such as before any sampler in the same scope.2) predecessor processor---PRE processors:The predecessor processor does some special wo
