How to save simple graphics drawn on canvas as gifs, bitmaps, etc.

I figured out how to draw a graphics object which is abstract for an application rather than an applet. Now, my question is, how do I save these simple graphics (lines, rectangles, circles,etc) drawn on canvas as gifs, bitmaps, etc. so that they may later be opened using other graphical viewers.
another question I was wondering was if graphics is a AWT only class (ie no better swing equivalent)
thanks

some things i have found so far are acme or java advanced imaging api... anyone know what is easier to use for my purpose?
it appears that when using acme, i need to use java.awt.image (does that mean I would have to convert the canvas to an image?) how do i save in gif format using java advanced imaging?
Please help

How to save a graphic

Hello All.
I was able to create a graphic using STAT_GRAPH_REF function module but now I want to control the buttons of the graphics window (I want to save the graphic into my hard drive). How can I do that?
TIA, Mauro.

Hi,
use the chart engine that is part of the IGS. Just have a look at the demo program GRAPHICS_IGS_CE_TEST where the class CL_IGS_CHART_ENGINE is used to create a chart. You can use such a chart for displaying and/or saving it.

How to save a graphic composition

I have a JPanel where several swing components are added. I'd like to apply some transformations to the resulting composition.So I'd like to save it before applying transformations in order to recover the original composed image every time I want to transform it.
How should this be achieved ?
Could I get an image from the jPanel Graphics context ?
Any hint ?
Thanks in advance. Jose Gonz�lez.

do you mean affine transformations?
AffineTransformation af = aGraphics2D.getTransform()
//do here your transforms
//reset to the original
aGraphics2D.setTransform(af)

How to save a Graphics with .jpg???

I draw a Picture on cavas ,and then I want to save it to an IMage with .jpg, and print it.
what can I do?
help me !!
Thanks in advance.

Turn the canvas into an Image or BufferedImage, or whatever, then import this package:
import com.sun.image.codec.jpeg.*;
Finally, here is a static util function:
<pre>
public void saveJPG(Image img, String prefix, String suffix, File dir )
String s = null;
BufferedImage bi = createBufferedImage(img);
FileOutputStream out = null;
try
File file = File.createTempFile(prefix, suffix, dir);
s = file.getName();
out = new FileOutputStream(file);
catch (java.io.FileNotFoundException io)
{ System.out.println("File Not Found"); }
catch (java.io.IOException e) { System.err.println(e); }
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi);
try { encoder.encode(bi); }
catch (java.io.IOException io) {
System.out.println("IOException"); }
try{ out.close(); }
catch (java.io.IOException io) { System.out.println("IOException"); }
System.out.println("JPEG Saved: " + s);
</pre>
If that doesn't help, try the JAI.

Can't figure out how to make a graphic expand in an animated gif (CS4)

I'm trying to make an animated gif where two of my graphics expand to the outer edges of the picture. However all that I can manage to accomplish is to have the opacity fade in or out. Is it possible to make a graphic expand in CS4?
Thanks for any help!

I'm not very familiar with animation using Photoshop. I have a small amount of experience using Illustrator, but not much. I'm not sure what a normal timeline is.
What I'm trying to do should be very simple. I want to emulate a tv screen flickering on, using 2 white bars that expand outwards from the center of a blackish background.

How to display graphics larger than canvas size?

How do I display graphics larger than canvas size in Java AWT?
I tried setting the canvas size() to a value larger than my monitor size, and then adding scroll bars to the canvas, but the scroll bars and the canvas won't go beyond the monitor size in pixels, which is only 800, so the large graphic I try to display gets cut off at the bottom.
How can I overcome this problem? Has anybody encounter a similar dilemma before?

Here are a few Links to a helpful Knowledge Base article and a White Paper that should help you out: http://digital.ni.com/public.nsf/allkb/BBCAD1AB08F1B6BB8625741F0082C2AF and http://www.ni.com/white-paper/10435/en/ . The methods for File IO in Real Time are the same for all of the Real Time Targets. The White Paper has best practices for the File IO and goes over how to do it.

Why can't there be a simple utility that shows me which device connected to my Airport is using how much of the bandwidth in a simple graphical or stats format without requiring me to be a level 10 Black Belt or Chuck Norris' paternal tooth fairy?

Why can't there be a simple utility that shows me which device connected to my Airport is using how much of the bandwidth in a simple graphical or stats format without requiring me to be a level 10 Black Belt or Chuck Norris' paternal tooth fairy?
I need to see who is consuming the most bandwidth and limit that user/device. A very simple and dare I say it, legal, moral, and normal wish.

They are not overloading the Airport. They are overwhelming the capacity of your Internet connection.
No. It's not "shared equally". That's not how packet switched networks function.
Most consumer grade routers do not have the ability to restrict bandwidth use on a per machine basis. You need relatively expensive (but readily available) equipment to do that.
How many people are on the network? It can't be that hard to hunt them down.

How to save diagramm in HTML format or PDF it

how to save diagramm in HTML format or PDF it

You have two alternatives. First of all, there are many utilities, some of them free that can put a "printer" on your printer list that really writes a PDF file. The one I use is free, called CutePDF. Once you have one of these installed, saving to PDF is as simple as print the diagram, choose the printer associated with your utility, then name the file.
I'm not sure if it is in your version of Designer, but all of the latest versions of Designer have a "publish diagram" utility. Just drop down the Utilities menu from the RON or the Design Editor. The bottom selection should be "Publish Diagrams...", which will open a dialog window. Choose the diagram(s) you want to publish, select Publish to File, enter a file name, and select a graphics format from PNG, GIF, JPEG, BMP or TIFF. You can easily add the file to an HTML page inside an <IMG> tag.

Having a problem saving the graphics on a canvas.

I'm having a problem saving graphics on a canvas. It draws on the canvas but when another window comes up the graphics disappear. I put in a method to take the graphics on the canvas and repaint it with the graphics. But this comes up blank. So I don't know why this is happening. It is probably the paint method but I don't know why. If anyone has any ideas could you please respond because I have had this problem for ages now and it's driving me mad and I have to get this finished or I'm going to be a lot of trouble. I'll show you the code for the class I am concerned with. It is long but most of it can be disregarded. The only parts which are relevent are the paint method and where the drawline e.t.c are called which is in the mouse release

I want to use Get Panel Image in Labview 5.0.1 and need details on how to save the BMP data generated

I am trying to generate an application that saves a copy of its front panel on completion. This is easy to do using an invoke node with Print VI to HTML but this does not work in an .exe format. I have seen elsewhere that you have to use the Get Panel Image method, but no details are supplied in LV 5.0.1 documentation of how to use the "image" data (1-D Unsigned Byte array) that is generated. I want to save this in a format that can then be read as a bitmap in any standard graphics package. Any assistance?

Hi,
If you'd upgrade to LV5.1 or 6 you could use the 'standard' vi's for this.
You need a VI called "Write BMP File.vi". It's not shipped with LV5.0.1.
This vi only uses 3 subVI's, so perhaps someone at NI can convert it and
send it to you (sorry, I won't, it's copywrited).
If you cannot get this VI anywhere, you'll need to figure out the BMP file
format yourself. It's not too complicated, but still could take some days.
Perhaps someone figured it out before LV5.1 was released.
Regards,
Wiebe.

Hi,
Yes, you need store data to table, and fetch it when page is opened.
Simple way is create table with few columns and e.g. with CLOB column and then create form based on that table.
Then modify item types as you like, e.g. use HTML editor for CLOB column

How to save an project in iMovie 10

I am familiar with iMovies 9 and using OSX 10.6.8. Unfortunately I have a new MacPro on OS 10.9.2 and iMovie10 (give me back my old MAcbook any day). I have finished making the movie and saved it on the desktop in mp4 format. All I want to do now is to find out is how to save the movie I have made so I can possibly get to it again to maybe add/delete things from it. In other words, I simply want to save it -
how do I do this?
can I save the movie in m4v format like I did in iMovie 9?
the mp4 format is 900Mb for 10 min, the 12 minute movie I did in iMovie 9 is 400Mb when both saved as 720p. Why?
Can you delete iMovie 10 from Mavericks and install iMovie 9
Many thanks in anticipation from a very frustrated Mac user of 8 years now thinking of going to Windows

Ok I think I've worked it out (did not know your could share to the theater, the icloud message made me assume theater was just for icloud) but I've another technical question about export quality and pictures in videos.
I just published four different quality movies (480p, 560p, 720p, 1080p) which only had a few average quality digital pics in them, just to create a short movie to compare.
I've always assumed that the quality of pictures was handled differently to video in that pictures would be fine quality even with lower quality setting, and the thing that really got hurt by lesser xxxP quality was the moving video not the pictures. But when I resized all four Quicktime movies so they were the same size and put them next to each other I could notice quite a difference in the sharpness between each of them. Since I'd rather have the pictures all used at their best quality will I have to choose the 60GB 1080p export function anyway at some point? It seems like such a waste of space and time when technically there are only about ten frames in the entire clip!
Surely there's some kind of video encoding language where you can make the file size reflect this? Kinda like what vector graphics did to bitmap formats for image files.
There must be a way round this ...

Curious: How does "Save for Web" reduce the file size?

I do know HOW TO USE "Save for web" -- no questions there. I'm wanting to understand better what's going on under the hood.
When I start with say, an 8x10 JPG at 300 dpi, I understand completely how bringing that down to 72 dpi yields a much smaller file. Simple math.
What I don't understand is how the "Save for Web" function can reduce that smaller file size so drastically at the same dimensions, still 72dpi, with negligible image loss (at least at the 80% quality). Maybe it's just my amateur eyes, but for everyday casual web pages, I can discern no significant difference between the two 72dpi images. (At lower quality settings, I do see differences.)
Can anyone explain a bit more of HOW Photoshop does this? Is it simply compression? For example, is it -roughly- analogous to converting an AIF sound file as an MP3?
Thanks,
cb

Thanks, that worked. I figure there was a setting in there somewhere and was even in the right tab, but didnt think to click on that.

How to save battery life (ipad mini)

When I'm away from home and I don't have my charger. What are some ways that will save my battery life? I know the basics like screen brightness and double tapping the home button to delete history. Are there more ways I can save lots of battery life?

See some of the links below.
Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.
