I have a 1024x1024 png i want to split it into 64x64 (256 equal parts)
i found a program that can do this but it's not free it's called "Split and Tile"
i would like to find out a free way to do this.
ImageMagick could do that for you with a simple one-liner:
convert -crop 64x64 source.png tile%d.png
http://arje.net/rasterbator and http://posterazor.sourceforge.net/" do not work. I have tried it. You may try Online image spliter.
Here, I will guide you how to upload and split your image in the website, since it is a bit tricky. Upload your image by clicking picture icon close to upload image.
Next, hit upload image and wait your image to be uploaded to the website.
At the upper center position you will now see a text split image. Look at the left side, you will see row and column. Adjust row and column as you need.
After you hit split image your picture will be automatically downloaded.

I basically want to make overlays like you know them from the package explorer in eclipse, a base image, and a smaller picture laid above in the bottom right corner. I used DecorationOverlayIcon for this and fist some pics from the already existing resources just to if it works. It the overlays showed up, but even though I had given the following instructions
imageDescriptorArray[IDecoration.BOTTOM_RIGHT] = alreadyExistingImageDescriptor;
DecorationOverlayIcon(baseImage, overlaysArray);
the overlayed image was very big. Than I made my icon, which is a 16x16 .png. It like the other pictures covers up the icon almost completely. How do I make the image smaller, do I have to convert it to a smaller size like 8x8 for that, or alternatively, how do I push it further down?
DecorationOverlayIcon doesn't resize anything so you must provide small images for the overlays.
There is also no way to change the calculated position of the overlays.
I created some presentation with a lot of small images.
The problem is - that those images were originally whole screenshots (1920x1080 px), which I used Impress' image cropping tool to take only small relevant parts of the screenshot.
If you ask why is it a problem -> the answer is that instead of containing ~30 very little image crops, my presentation contains ~30 1920x1080 sized images, and just shows them according to the current crop settings.
It causes the saving process to take ~10 seconds, the output file is very large and everything works slowly because of the complex rendering process.
Is there any way to discard the cropped parts of the images?
The cropping tool is not good for making such large changes. From https://wiki.openoffice.org/wiki/Documentation/OOo3_User_Guides/Writer_Guide/Cropping_resizing_rotating (and this is true in Impress as well):
If you crop an image in Writer, the picture itself is not changed. If
you export the document to HTML, the original image is exported, not
the cropped image.
Instead, use separate image software to do the cropping before putting the images into Impress. I typically use IrfanView.

I am searching for a tool on web but didnt got any success their at all. I want to have something like upload and preview the image as background as repeated one or any other alternative...
I have this sample:
How can I preview and cut the image as a perfect background image as repeated one. Is it possible in Photoshop or in some similiar products?
The trick i have recovered is crop a part of the image in a big canvas of Photoshop and then making the deuplicate copies of the layers...
If the image seems like irregular it means the cropped image is wrong so you have to change with a other or larger part of the image...
If it is regular and doesn't cut at the side onto the edge, it means image is perfect making background repeated...
Thanks...
i am using open xml sdk to copy slides into another presentation , when the slides are copied and my desired presentation is generated , I iterate through each slide of the generated document and replace its existing images with the image of my choice , the process is executing and the images gets replaced , but here is the bind , if the dimensions of my images are larger then the image in the document , the image gets cropped to fit to the size that was previously occupied by the replaced image .But if i do the whole process manually , by right clicking with my mouse , power point changes the dimension of the image its get shorter but its not cropped and the whole image is displayed ...
so what approach should i go for , do i have to change some xml settings through code , or do i have to change the dimension of my images using c# classes , what is the right approach to tackle this issue???
guys i will be anxiously waiting for your response ......
Better change the image before replacing the image in your target presentation file. As power point is going to embed your image in the file itself, you can reduce the size of the overall generated file if you compress the images to required dimensions before replacing.
Changing the dimensions in the xml is also a valid idea but you are embedding images into the file without any added advantage.

i am converting the image into thumbnail format and sending it to server and i want to convert it back to original size while receiving can any one please tell me how to resize the image to original without loosing quality.....
i tried directly to displaying the image in image view but the quality of the image is missing ...
can any one please help me how to maintain the quality of the image .......
Downscaling is irreversible, some information lost forever.
What you're asking isn't possible. You can't enlarge an image while maintaining the same quality. If you think about an image as a mapped array of pixels (literally, a "bit-map"), this makes sense. The image is saved with a fixed amount of data, and that's all you have to work with when you resize it. Any examples to the contrary (like TV shows) are purely fictional.
Investigate using vector graphics instead, which can be resized at will without a loss of quality.
you simply can not convert an image from thumbnail to original size and retain the quality it had in its original size.
if you want to display the image full-size, you have to send the full-size image.
You could think about using a Vector image? They do not lose quality when resized. But I have no clue whether you can use them for thumbnails in iOS.
See this wiki page for more info about Vector graphics.
