converter

I'm trying to dynamically generate a small MP4 audio+video file directly from my Android app. My original plan of attack: The user enters some basic song data (a chord progression, etc) and the app builds a MIDI file. The system builds chord diagrams for each chord, and using a MIDI reader it generates the animations frames array that is timed to the MIDI Convert the MIDI into a raw PCM audio data <-- this S.O. question is specific to this point Apply the raw audio to the animation frames - and encode the audio and video frames into an MP4 Provide the resulting MP4 video to the user with

I have been looking to convert a .pptx file to a .pdf file through a Python script for several hours but nothing seems to be working. What I have tried: I have tried 1) this script which calls windows32.client, and 2) unoconv , but none of them seem to be working for me. Problems encountered: Using script from first option throws up an error ( com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147024894), None) ), whereas in second option Python can't seem to recognize unoconv even after installing it using pip. I also saw some recommended Pandoc , but I can't

i wonder if it is possible to cascade converters when using wpf databinding. e.g. something like <SomeControl Visibility="{Binding Path=SomeProperty, Converter={StaticResource firstConverter}, Converter={StaticResource secondConverter}}"/> is it possible at all or do i have to create a custom converter that combines the functionality of converter A and B? You could try to use a MultiBinding , and bind twice to the same source, but with different converts on the single bindings. Something like: <SomeControl> <SomeControl.Visibility> <MultiBinding Converter="{StaticResource combiningConverter}">

I have a form page that has an inputText field that accepts a date. We have a converter that converts the string from the textbox into a Date object (ie. "2011-03-01" to java.util.Date("2011-03-01"") ) If the string is not a date, like "123" then a validation error message will be displayed like "value (123) must be a date". Currently, in my .properties file, I see: javax.faces.converter.DateTimeConverter.DATE=value ({0}) must be a date I need to make this error message more clear by specifying exactly which field must be a date. (As there could be more than one date text fields on the form).

this question is quick and simple. I've a 2d array of floats ( 0,0000000 to 1,0000000 ) and i want to convert those numbers to a color value ( #000000 to #ffffff ). note that i'm talking about just grayscale values. 0 = black | ... | 0.5 = middle gray | ... | 1 = white does anyone know how to do that with javascript ? thx. chrmod Grayscale values in hex are those which got symmetrical distribution or Red, Green and Blue, e.g.: #111111, #5B5B5B, #A2A2A2. To convert decimal number to hexadecial number you can use: var number = 42; var hex = Number(parseInt( number , 10)).toString(16); hex // =>

Is there a faster way than BitConverter.ToInt32 to convert a byte array to an int value? Marc Gravell If I remember correctly, that implementation uses unsafe code (treating a byte* as an int*), so it will be hard to beat, but the other alternative is shifting. However, from lots of work in this area, this is so unlikely to be a genuine bottleneck as to be irrelevant. I/O is the main issue, typically. GetBytes(int), however, is more expensive (in high volume) due to array / heap allocation. Gabe I actually tried several different ways to convert four bytes to an int: BitConverter.ToInt32(new

I am searching for a way to convert a XML-Object to string. Is there a way like $xml.toString() in Powershell? Stanley De Boer You are probably looking for OuterXml . $xml.OuterXml should give you what you want. How are you creating the XML object? Typically, if you want an XML string from an object, you'd use: $object | ConvertTo-Xml -As String 来源： https://stackoverflow.com/questions/15410455/powershell-convert-xml-to-string
