How to crop multiple part of image file in android?

show this image in multiple part of crop.and save this multiple crop parts in different files.

You can do it with XML ImageViewes
Maybe you can play with the scaleType and scaleX-Y (example.: with a bar) and you can save the ImageView Bitmap as a File or a Drawable in the resources.

Android how to load Image file with different extension using Picasso

This is a different situation. I want to load a image file which has stored with different extension like 'photo.xyz' instead of 'photo.jpg or photo.png' using Picasso. to avoid image from gallery i am storing image like this. Please help me is there any option to show like this.

Neither Picasso nor Android (which does the actual image decoding) cares what the file name is. It can be anything. The type of the image is always determined from the first few bytes of the actual image data.

As a small workaround you can programmatically put .nomedia file into your app folder to prevent images to be cached by mediaserver and displayed in a Gallery app.

SVG image not display

i have converted a psd file into svg, it works good at browser but not works on android native applications, how can i do this?
ImageView imageView = (ImageView)findViewById(R.id.img1);
imageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
//Parse the SVG file from the resource
SVG svg = SVGParser.getSVGFromResource(getResources(), R.raw.android);
//Get a drawable from the parsed SVG and apply to ImageView
imageView.setImageDrawable(svg.createPictureDrawable());
This is the code i used to display svg image. it works when i used simple svg images, but it not works converted svg images using illustrator . how can i do?

I am guessing that your SVG just contains the image from the PSD. Is that the case?
If all that the SVG contains is a bitmap image, then you are not really using SVGs for their proper purpose (vector art). You would be better off just converting the PSD to a JPEG or PNG and loading that into an ImageView.
However, if you are definitely sure you want to load an SVG, then the solution depends on which SVG library you are using.
svg-android: As far as I know, it doesn't support <image> elements, so there is no solution
AndroidSVG: supports <image>, so it should work as long as the device has the memory to load the image. If the image is embedded in the file, you should be fine. If it references an external image, you will need to pass in an SVGExternalFileResolver so it knows how to find the bitmap.

Show Tiff format image in Android

I am using ImageView to showing the .tiff formatted image, but I am getting error of NullPointerException.
I am converting the image file into byte array and then setting it in ImageView.
How can I show this tiff file?

You cannot set the tiff image on a ImageView in android directly. http://code.google.com/p/tiffonandroid/source/browse/ this is a sample tiffviewer. This might help you

Tiff has images stored as rows of bytes starting at defined offsets. So you can easily retrieve single rows to build the full image.
If you open any tif file in hex editor you will see that first 4 bytes mark tiff by code. And next 4 bytes give offset for metadata about tif image.
Use random access file to open image tif file, then seek the offset and you land into metadata space.From here you can pick offset of required image rows. Then go and get it..
If we needed full load of image like jpeg or BMP, then collect and combine all these rows after decompression, if any. Then you will get the full image

What is the most efficient way to load my stored JPG file into the ImageView?

I have valid JPG files and now I want to load them into a layout containing an ImageView. I have code to findViewId(R.id.myimage). I followed some sample code using File but it did not work. The file is stored at /data/data/com.myapp/files/someimage.jpg.
What is the easiest and efficient way to load and display?

((ImageView)view).setImageBitmap(BitmapFactory.decodeFile("/data/data/com.myapp/files/someimage.jpg"));
With the few info you give that's all I can do.
