Why do my Bitmap and JPEG images get distorted?

JPEG is not a lossless compression format, so every time you save an image as a JPEG, some information is lost by the JPEG approximation algorithm. \nTo prevent this, either save as an uncompressed format, such as bitmap, or use a lossless compression format, such as PNG. You may also use software to adjust the compression factor for your JPEG to decrease information loss.\nA good piece of free software supporting these functions is IrFanView, which can be downloaded at the link below.

Be sure the picture is easily accessable (My Documents or Pictures).\n\nFormat > Background > Fill Effects > Picture > Select Picture >\nOkay > Apply to All

If you have a graphics card, try updating your drivers. If you have an Nvidia card, update through Forceware. If you have an ATI card, update through Catalyst. \n\nXP Service Pack 2 oftens causes images to become blurry through driver conflicts, so try doing a System Restore if you recently put it on.\n\nFor your computers performance, try disabling background applications. To do this, click 'Run' on the start menu, and type 'msconfig'. Go to the Startup and Services tabs and disable as necessary. Be cautious with Services; try Startup first. Then, restart your computer.\n\nMake sure no firewall is blocking any programs. Make sure you only have one firewall.

when you are saving the file, there should be an option to designate what type of file you want it to be . . . make sure you select "jpeg".

if it's very small it gets pixelated when you zoom in (that's what you mean unclear i guess).\nI'm afraid you can't do many things with small pictures, not only in photoshop but in any picture processing software.\n\nTry to enlarge it a bit: go to Image > Image Size... then type\na new width and height figure a couple of hundred above the figures it says, hit ok and see what happens. For sure the image won't be crisp, but it's the best you can do at this stage.\n\nAlways try to get the largest images possible, with small images you cannot do anything really.\nI hope this helps!

No, there's nothign wrong.  As you shrink an image, it will appear fuzzy as it has to remove pixels to account for the size difference. If you expand your image back to it's original state, you'll notice it won't look the same anymore, as pixels have been removed.

It should be possible to save the image and open it as a raster file, although the quality may not be as high. You would also have to register the image manually which can take some time and may cause greater error. If you do this, make sure the projection is correct!

Check your images are at 72 dpi as that is the correct size for the screen. Any higher is for printing.\nMake your photos even smaller.\nCheck they are saved as Jaypegs.\nYou can get Photoshop on a 30 day trial, and you can use the Save For Web option. It will compress the jaypegs, you can choose the rate of compression. There'll be little difference at '80', some photos you can take as low as '60'.\nOr try Irfanview, its free.\nhttp://www.eecs.wsu.edu/paint.net/  -Paint.net Paint with layers.\nhttp://www.irfanview.com - useful graphics tool

Here you can find links to implementations of Deflate (page down to "DEFLATE" heading) and JPEG ("JPEG Hardware Compressor" heading) algorithms.\n\nHope it will help.

I bet you picture isnt the correct format.  (.jpg, .tif)

I have never done it (or tried it) for JPG, GIF, etc. but I have done it for BMP images. I think the others need decompressed first, but for BMP:\n\nCDC ScreenDC; //define this in your header file\n\n//in your open file routine \nCPaintDC dc(this);\nHANDLE BMPHandle;\nHDC TmpDC;\n\nTmpDC = CreateCompatibleDC(dc);\n\nBMPHandle = ::LoadImage( ::AfxGetInstanceHandle(), "my.bmp", \nIMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);\n//my.bmp is the name of the .bmp you want to load.\n\nSelectObject(TmpDC, BMPHandle);\n\nBitBlt(ScreenDC, 0, 0, 800, 800, TmpDC, 0, 0, SRCCOPY);\n//the first 0 is the x coordinate of the upper left corner (change to where you want it)\n//the second 0 is the y coordinate of the upper left corner (change to where you want it)\n//the first 800 is the width of the bitmap\n//the second 800 is the height of the bitmap\n//the fourth 0 is the x coordinate of the bitmap (leave at 0 to get the whole bitmap)\n//the fifth 0 is the y coordinate of the bitmap (also leave at 0)\n\nInvalidate();\nDeleteObject(BMPHandle);\nDeleteDC(TmpDC);

Pixelization and higher resolution.

How come? Maybe you should scroll down the file format to .jpeg.

PNG format uses loss free compression, but file size depends on pixel count.\n\nConverting from jpg to png will usually cause an increase in file size without changing the quality if you retain the picture resolution.

You should consider reducing the files size by either reducing the picture size, or the picture quality. This is pretty easy to do with Photoshop. If you will only use the pix online and don't plan to print them then you should reduce the quality.

Yes - the only problem is that image will probably be unrecognizable.  The more you compress an image the worse it looks.  1K is a little small for effective image work at that size.  Note - the pixel dimensions are what is important i.e. 416x416.  The dpi doesn't change the amount of information in the image.  It's used to know how to scale it on a printer.\n\nYou can do this in just about any image editor.  The JPEG format allows variable compression settings.  If you set it low enough you can go below 1K.\n\nDo this in your own software, you have to find an image library.  On Windows, GDI+ can load and save images in a variety of formats (including JPEG).  When saving you can set a quality level that indicates the amount of compression.  Most jpeg routines allow quality to vary 1 - 100 with low numbers indicating more compression (and hence less quality).\n\nI'm not familiar with Unix/Linux libraries.

If it is only one image, you can browse to the image location in the properties of the picture box through the form designer. It should support jpeg. Through code you can do:\n\nBitmap b = Image.FromFile("c:&#92;&#92;myfile.jpg") as Bitmap;\npictureBox.Image = b;
