MIME Type

[saifulhq]

i just learn about MMS with MMSMIDlet on forum.nokia.com

but i read that MIME Type for image just image/jpg, image.gif

how with image/png, i am use n73, how to send PNG Image, n how to get Byte[] from PNG image, i read manual Image but not found function return Byte[]

hi saifulhq,

encoding are set explicitely by you when calling getSnapshot(...)

byte[] pngImageData = videoControl.getSnapshot(null);

(note quite sure which is default on N73: png or jpeg encoding when passing null - mipd implies png though)

byte[] pngImageData = videoControl.getSnapshot("encoding=png")

use property:

video.snapshot.encodings

to get list of encoding supported on given device but N73 being 3rdEd FP1 device should support png/jpeg/gif/bmp if I'm not wrong:
check also this feature matrix support:

hi saifulhq,

i've just read in FN doc:
http://www.forum.nokia.com/info/sw.n..._0_en.pdf.html

The parameter for getSnapshot is a String stating which format the data should be in; if it is null, then the data will be in PNG format, which is guaranteed to be supported by all implementations.

so PNG is default format,

i am use s60 and nokia prototype 4

i want to send MMS with png file, ia have file png called picture.png at folder res, i get the pixel from the picture with getRGB. then i rotate the picture 180 degrees.

so, can i send the new picture with MMS, because i read at manul png image have not return byte[].

if i send MMS, i am send byte[] can with inputStream. can i input my new picture to inputStream.

try {
image = Image.createImage(fileName);
rgb = new int [image.getWidth() * image.getHeight()];
baruRGB = new int[image.getWidth() * image.getHeight()];
image.getRGB(rgb, 0, image.getWidth(), 0, 0, image.getWidth(), image.getHeight());
}catch(IOException e){
System.err.println(e);
}

for(int i=0 ; i<image.getWidth()*image.getHeight() ; i++){
baruRGB[image.getWidth()*image.getHeight()-i-1] = rgb[i];
}

baruImage = Image.createRGBImage(baruRGB, image.getWidth(), image.getHeight(), false);

can i send baruImage via MMS

hi saifulhq,

if you are sending mms to another midlet (not into client inbox) then you don't need to create correctly png-encoded byte data, its only needed if you sending mms to inbox,

I've found Java 1.1 compatible png encoder:
http://javaboutique.internet.com/PNG_Encoder/
maybe you can use it directly (not sure though) or use as guide for creating your own encoder,
