Furthermore, are there any sort of tools available to aid me in doing so? //---------------------------------------------------------------------- // Global Declarations //---------------------------------------------------------------------- program ::= file+ file ::= newline? ( declr newline )* func* declr ::= typedef | globals | native_func typedef ::= 'type' id 'extends' (

由 ℡╲_俬逩灬. 提交于 2019-12-12 04:34:09
问题 I've got a Datepicker and I'd like to allow multiple formats for users.

Weird phenomenon when converting RGB to HSV manually in Matlab

由 雨燕双飞 提交于 2019-12-12 04:23:09
问题 I have written a small Matlab funcion which takes an image in RGB and converts it to HSV according to the conversion formulas found here. The problem is that when I apply this to a color spectrum there is a cut in the spectrum and some values are wrong, see images (to make the comparison easier I have used the internal hsv2rgb() function to convert back to RGB. This does not happen with Matlabs own function rgb2hsv() but I can not find what I have done wrong. This is my function function [ I

If anyone can throw some troubleshooting/debugging tips for this sort of problem it would be greatly appreciated. Using log statements I have verified

What is the purpose of converters in jsf? [duplicate]

由 心已入冬 提交于 2019-12-12 03:29:13
问题 This question already has answers here : Conversion Error setting value for 'null Converter' - Why do I need a Converter in JSF? (2 answers) Closed 3 years ago . It appears that a converter usually has two methods getAsObject() and getAsString() , which will convert Object into or from strings. Why do we need to do this? For example, in dataTable we can always bind an object with var . Why can't we do similar things here? 回答1: In the end the client (usually a browser) will receive a rendered

Convert VERY large ppm files to JPEG/JPG/PNG?

由 为君一笑 提交于 2019-12-12 02:54:30
问题 So I wrote a C++ program that produces very high resolution pictures (fractals). I use fstream to save all the data in a .ppm file. Everything works fine, but when I go into really high resolution (38400x21600) the ppm file has ~8 Gigabytes. With my 16 Gigabytes of Ram, however, I am still not able to convert that picture. I downloaded couple of converters, but they couldn't handle it. Even Gimp crashed when I try to "export as...". So, does anyone know a good converter that can handle really

LaTeX to png conversion

由 拥有回忆 提交于 2019-12-12 02:05:39
问题 Following this previous question, I thought I could first convert the output of stargazer (latex code for summary statistics table) to png, using R commands (like dvi, dvips, ...) inside an R chunk or, in the worst case, invoking system commands (see this post), and then import the produced png into my Rmd file, using a command like ![alt text](summary_lm.png) Do you think this is possible? Could you show me how to do it, because I had no luck? 回答1: You can use the object tag to embed a PDF
