join pieces in an image

Umangj

heyyy pls help me... i need to join these puzzle pieces in an image..... the gap in b/w the pieces is the transparent color where alpha component of the pixel is 0, for example: i need to change an image from this: http://www.freeimagehosting.net/uploads/th.61647e9923.jpg to this: http://www.freeimagehosting.net/uploads/th.11322f3595.jpg

First up learn where the shift key is, it will help you. Secondly you haven't actually asked a question. I can infer from your message that you can't work out how to do this. But what I am not sure is if this is due to not understanding a nuance of c# that has caused you to go in circles with an implimentation problem or because you are thick. Please can you let us know!

For You: I just want to know how should i move the pixels so tht transparency between the pieces is gone.I have tried shifting the pixels row by row and also column by column but that is not working.... jus tell me any other way to do this....

You need to read my image processing articles. As the lines are not straight, you need to iterate over each row, and then build a new row using only non transparent pixels. If you can't see which are transparent, you may need to match based on color alone.

Here, I can see which pixels are transparent... Now, if I build each row again using only non transparent pixels then there will be problem at the last rows of each puzzle piece as the transparent color there need not to be shifted as the puzzle piece below it will fill it..... Thank you for replying...

Hi, if I had a single pixel with alpha=0 where I would like it to be 255, I would probably open up my toolbox and modify that pixel somehow. And if I had several, I would consider a loop, maybe even two of them. Of course, if the information happens to be absent, I am not a magician. BTW: your hardest problem may well be that one image is 150*106 while the other is 150*107 :)

Great, now you've asked a question and it looks like you've got spelling mastered. If you haven't read Christian's article do so. The basic premise is that you must know the transparancy colour. Will the blocks always move on just on plane or can they move on both? You need to identify each block of image and move it enmase. Otherwise you will not know if you're going left/right or up/down. Have a go and see where it's going wrong. Then come back and ask for some help at the next stage. Unfortunately, without knowing the method you are trying to employ it is rather difficult to help just yet. Now read Christian's article (he's v. clever) then have a go at a solution. If you get, come back and ask for some help where you are not sure. And have a Gin'n'Tonic, that helps as well. ;)
