Getting Image from BitmapField
I'm wondering is any way to get an image in any form that was modified in BitmapField?
May be I've got not very good application architecture, that I'm need such functionality? But I see getText method in TextFiled, and I'm wondering why I can't get image?
I want to do next thing:
1. I have a CLDC application with Bitmap field that shows a bitmap image.
2. I have to draw some additional graphics on that bitmap and I do so.
3. I have to save modified image to file system or send it.
An I have problems with getting this image back.
Can someone give me an advice how it could be done?
to set your edited bitmap to the bitmapField you must surely draw it to a bitmap first? ie. you can't draw directly to the bitmapfield - you must be drawing to a bitmap somewhere so why not just cache or save this?
jfisher, thank you for reply but it is not clear for me what I have to do.
I'm using JDE 184.108.40.206. In BitmapField class I see method paint(Graphics g);
So I can override this method in my class and paint directly at BitmapFiled and I do so.
I do not see a possibility to paint at Bitmap itself.
Could you, please help me?
aah i see. instead of drawing straight to the bitmapfield draw to a bitmap and then populate the bitmap field for display:
Bitmap myBitmap = new Bitmap(240, 100);
BitmapField myBitmapField = new BitmapField(myBitmap, BitmapField.FOCUSABLE);
Graphics myGraphics = new Graphics(myBitmap);
myGraphics.fillRect(10, 20, 10, 10);
myGraphics.drawText("myText", 20, 5);
Thank you, now it is works much better.
One more quersion.
Is any way to convert that Bitmap to EncodedImage to save or scale at screen?
