I have some images that I exracted using dump_image. I'm trying to restore them with the MTK Flash Tool. The ones that go on FAT partitions seem to flash fine but the ones that go on yaffs2 partitions don't work.
I think I need a way of converting the images I extracted to yaffs2 images.

I created img.yaffs2 using mkyaffs2image and then mounted it into Ubuntu MTD NAND flash simulator. so if I use 'cat /proc/filesystems' I can see yaffs and yaffs2 and by 'cat /proc/mtd' I can see /dev/mtd0에 Nand simulator partition 0. (block size is 0x4000).................
View 4 Replies View RelatedNeed to display images downloaded and extracted from a zip into the "/files" directory of the app. the images are getting in there properly as far as i can tell - i am able to extract them from the emulator and view/open them from my desktop. but every attempt, every variation of code i have found and tried so far has failed (Tag: skia / Text: --- decoder->decode returned false).
My latest construct, which does work for image files downloaded separately and uncompressed :
Code:
String imgFile = new File(getFilesDir(), "myImage.jpg").getAbsolutePath();
ImageView myImageView = new ImageView(this);
Bitmap bm = null;
try{
bm = BitmapFactory.decodeFile(imgFile);
myImageView.setImageBitmap(bm);
} finally{
mainLayout.addView(myImageView);
}
And here is the construct i am using to handle the zip extraction. I assume this is where the problem lies but i am clueless as to what i could possibly do differently and to what effect:
Code:
ZipInputStream zis = new ZipInputStream(fis);
BufferedInputStream in = new BufferedInputStream(zis, 8192);
ZipEntry ze;
while ((ze = zis.getNextEntry()) != null){
File dest_file = new File(getFilesDir(), ze.getName());
[code]....

View 6 Replies View RelatedWe know that the ROM is installed to the /system partition. Likewise the kernel ie boot.img is installed to the /boot partition of the device. I tried hard but could not find any reference to such a /boot partition(directory) in the root of the device. I would like know whether it is hidden or disguised as something else. The script that flashes the custom kernels has the following line
Code:
package_extract_file("boot.img", "/dev/block/mmcblk0p9");
(What is the block code for system and other partitions?)
Is mmcblk0p9 the /boot partition? Moreover /dev/block has no reference to boot or mmcblk0p9. So where exactly is the kernel being extracted? The boot.img comes packaged as zImage + ramdisk, In other words where are zImage and ramdisk extracted to, in the root file system and in what form? Is the ramdisk responsible for the creation of the root files system(/dev, /proc, /data. /system, /sys, /sbin etc)?

View 2 Replies View RelatedI want to convert a image into Base64 format and send it to server. I have one Base64 class which accept byte array and return a string.I am sending image into chunks of data.I am creating creating one chunk of 100kb. If image is less than 100 kb then image is uploaded on server, but if it is greater than 100kb (i.e when it requires more than one chunk) then it will not uploaded. I think it is because I am converting image into Base64 in parts and on server it decode it only in one shot. Now I want to send a image for conversion of Base64 only in one chunk. But if image is too large then it throw OutOfMemoryException (Obviously after all it is mobile having very limeted resources).

View 4 Replies View RelatedIn my Android App Activity, I have a RelativeLayout with one ImageView and a couple of TextViews being populated at runtime. I also have a Save button in the activity that I use to save the image in the ImageView to the device SD Card. Now what I really want to do is Convert the elements (image and the text in the RelativeLayout) together to a PNG image when the Save button is clicked and Save it to the SD Card. Have anyone tried a conversion like this before? It would be very helpful if someone can give me some hints or code snippets on how to go about doing this?

View 2 Replies View RelatedI am trying to use one of these algorithms to convert a RGB image to grayscale :
The lightness method averages the most prominent and least prominent colors:
(max(R, G, B) + min(R, G, B)) / 2.
The average method simply averages the values: (R + G + B) / 3.
The formula for luminosity is 0.21 R + 0.71 G + 0.07 B.
But i get very weird results ! I know there are other ways to achieve this but is it possible to do this way ?

Going through the list of files (via Astro) there is indeed a file named 'HTCflashplayer'. So what exactly is this flash-player for? Does it need to be extracted and launched somehow? Because it sure as hell doesn't play much flash!

YAFFS2 is a file system that was designed specifically for NAND flash, which is supposed to be more robust than EXT3 file system in terms of NAND flash.
