Discussion: Images in applets
- Thread starter krip
- Start date
I struggled with this for a bit, when I wrote a simple applet for my web page.... Here is how you can do it...
I am just dumping the html code and the java code since i really don't have the time to explain, just basically jar files work like zip files. In the java program you simply have to make sure the main program knows where to find the .gif file or whatever - here you go

Programmer Tom Moses, do not care if you use this just give me credit and do not use
this for a school projects your just a lamer if you do so. ackka
Very simple applet, the repeating rectangle give the illusion of 3d
The z index in the CardData array controls which will be displayed
first, a z index of the highest number will mean it is displayed on top since this
was the easeist way to program and it is logical so you can possibly add as
many possbile cards as you want

You either misunderstood me, or I misunderstood your code..
I need to be able to build an Image out of it's raw byte data, or alternately be able to create Image objects out of gifs in a jar file.
The only place you got images in the code (that I could see) was in this line:
CardDataArray.CardImage= getImage(getCodeBase(),getParameter("image" + i));
and well I have a seperate Jar file for images that hold some hundreds of Gifs with similira names (under different paths). I can't see how this would help me, but I might be mistaken as I work to be compatible with SDK 1.1.7 and you might be working on a newer version.
again thanks... Ira

Ira,
sorry to do this to you. I have a question about your question.
Are you working with .gifs in this way for reasons of compression? I have a project on the horizon where I'll be dealing with hundreds possible thousands of .gifs.
I was imagining a way to store them in binary?
we have similar idea, no?

ira ...
i think what acka is trying to say is that if you have the image file in the jar file under the specific directory then just tell the program where it is and it will find it.
i think that,
import java.awt.*
Image myImage = ToolKit.getImage("images/image1.gif"
i think that that will work if you have image1.gif in the jar file under a subdirectory images ... try it
and lupine .... ummm i dont know, i think that if you want to save space with the images try maybe saving them as jpegs, they tend to be smaller, what kinda images are they and what are you using them for.

Sorry for the confusion krip I wrote a FAQ on how to use Jar files in images and text files
