Scale a Bitmap and preserve alpha, on BlackBerry

由 ▼魔方 西西 提交于 2019-12-09 03:46:05
问题 I am trying to scale down a Bitmap that contains transparency. Unfortunately, all three methods I've tried result in white where there should be full transparency. I would like to maintain the transparency. The bitmap I am scaling is always square, so my functions assume that: private static Bitmap scale1(int edge, final Bitmap res) { int factor = edge == 0 ? Fixed32.ONE : Fixed32.div(res.getHeight(), edge); Bitmap scaled = PNGEncodedImage.encode(res). scaleImage32(factor, factor).getBitmap()

String Formatting + Blackberry + java

由 [亡魂溺海] 提交于 2019-12-08 19:00:30
I am facing a bit problem with formatting of string.

The problem that I am facing is that this approach doesn't work fine when I append

how to upload the file through http to the website? (Blackberry)

由 ◇◆丶佛笑我妖孽 提交于 2019-12-08 14:09:30
I need to upload a file through http or ftp to the website in blackberry jde. High level view: You open an OutputStream from an HttpConnection and write your data into that output stream. The main problem is going to be choosing which network connection to use (I recommend looking at this, unless you're on OS 5.0 which has a similar feature built in) . As to uploading through FTP that will be somewhat more difficult as there is no support for FTP built into the BlackBerry API instead you'll have to look at using a SocketConnection and implementing part of FTP yourself. Here's some code to get
