Xcode 4 archive results in slow/unresponsive Organizer & pngcrush process takes up 100% cpu

由 二次信任 提交于 2020-01-01 08:45:41
问题 sorry about the rather confusing title, but I tried to get in as much info as possible. Problem: I'm trying to archive my iPhone app into an ipa file for OTA testing (via TestFlightApp) - so in Xcode, I perform a Project > Archive. After the archive is successful, it opens the Xcode Organizer to create the ipa file. BUT as soon as Organizer is opened, Xcode becomes VERY slow & essentially unresponsive. So naturally I open Activity Monitor to see what's going on and there's a process called

Javascript render jpeg binary data from variable

由 柔情痞子 提交于 2020-01-01 07:04:34
问题 How to render JPEG/PNG file data contained in Javascript variable? Is it possible ? What javascript libraries needed ? Browser in use is FF / IE. Thanks 回答1: Modern browsers support inline images. So you could convert the binary data to a base64 encoded string and then append it to the DOM: var img = document.createElement('img'); img.src = 'data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub//ge8WSLf/rhf/3kdbW1mxsbP//mf//

参考链接： https://blog.csdn.net/tragicguy/article/details/21893065 https://blog.csdn.net/xdrt81y/article/details/17588961 主要有三步： 一、 修改CListHeaderItemUI的的基类， 由CControlUI 改为CContainerUI class DUILIB_API CListHeaderItemUI : public CContainerUI 修改CListHeaderItemUI中所有出现的CControlUI ，全部改为CContainerUI。 二、重写CListContainerElementUI::SetPos函数 void CListContainerElementUI::SetPos(RECT rc, bool bNeedInvalidate) 中setpos函数，只需要重写这个函数的就行了。 如果不重写这个函数，会造成，第三列数据也写在第二列，数据重叠了。 三、XML的编写： 主XML： < List name = "listview" padding = "15,15,0,0" width = "350" height = "340" headerbkimage = "list_header_bg.png" style = "list

Convert 32 bit png to 8 bit png with ImageMagick by preserving semi transparent pixels

由 早过忘川 提交于 2020-01-01 02:31:13
问题 I want to convert 32 bit png to 8 bit png with ImageMagick, but semi transparent pixels are lost. How to solve this problem? The command that I am using is the following convert original.png PNG8:output.png 回答1: Apparently, even though the PNG format actually allows any and all of the colors in an 8-bit indexed color PNG to be fully or partially transparent, ImageMagick's "PNG8" format specifier only supports GIF-style 1-bit transparency. It's possible to produce indexed 8-bit PNGs using

Fastest PNG decoder for .NET

由 ﹥＞﹥吖頭↗ 提交于 2020-01-01 01:14:20
问题 Our web server needs to process many compositions of large images together before sending the results to web clients. This process is performance critical because the server can receive several thousands of requests per hour. Right now our solution loads PNG files (around 1MB each) from the HD and sends them to the video card so the composition is done on the GPU. We first tried loading our images using the PNG decoder exposed by the XNA API. We saw the performance was not too good. To
