.bmp and .png
I thought of saving my files in .pgn formats, mainly because it has
lossless compression. I already have a lot of photos but in .bmp.
I tried the following:
convert foo.bmp foo.png
convert foo.png bar.bmp
and got foo.bmp == bar.bmp.
When using gimp and tried to save a previously read .bmp file as .png
and then I use "convert" to convert it back to .bmp, I don't get an
equal file! Besides gimp shows a dialog box asking for some options
whose meaning I don't know.
Any help/enlightment on this? Why those options if everything I need is
to save a photo "exactly&quo...PNG to PNG alpha (on Adjust)
I have a black-on-white greyscale PNG diagram which is antialiased on a
white background. I'd like to rejig it so I have a completely black PNG
with the 8-bit alpha channel being the original diagram. In other words the
black on the original diagram means 0% transparency and the white on it
means 100% transparency. So that effectively it gets anti-aliased onto
whatever colour I place it on (a blue background means a black-to-blue
Is it possible to do this with RISC OS? Adjust Paint does alpha sprites and
PNGs, but I can't work out how to write the alpha channel other than ...US-TX-Austin: Sr. Design Eng., Transistor level design, Analog design, CAD, RF m (45322132429)

...PHP (GD) created transparent PNG: AlphaImageLoader makes black parts transparent instead of transparent color set with PHP
I have a problem with PHP (GD) created transparent PNG and Microsofts
You will immediately see what the problem is if you view
http://www.useful-scripts.biz/test/transpng/transpng_2.php with IE 7
or Firefox and then with IE 6. It seems that the AlphaImageLoader
works correctly on a PNG image that has been created with an image
processor and then uploaded, but not with a PNG image created with
PHP. It seems to ignore the transparent color set with PHP and instead
to render the black color transparent.
The image in question was created using this code:

Hello, I've searched and d/l'd but cant seem to find a way of creating
a semi-transparent drop shadow for an image.
Let me say, be fore I go on, I *do not* want one of those scripts that
resizes your image a bit to the left and bottom, and then grafts a
shadow onto it. I want to use a full shadow (it would be about as big
as the image) and shift it a bit with CSS. So, I will have the image
sitting in a DIV which will have the shadow as a bg. This works fine
doing it manually.
So, I would like to find one of two alternatives:

I looked at the deflate and couldn't figure out much
from RFC 1951.
Does there exist any materials that explain the deflate
step by step just like the explanation for other
compression schemes (Huffman,LZW). Any good pointer
would be highly appreciated.
And coming to the point, I compressed the data by LZW
using 11 bits encoding. so the maximum entries on
the table can be only 2^11=2048. Now when I see the
compressed data I found that the code repeats.
A sample of the code generated are(it is just a part of the
total encoded data):

There seem to be at least two flavours of PNG files with transparency.
The transparency in some images does not always work, in particular in
Internet explorer and Corel Paint shop Pro.
Java generates files with this "iffy" sort of transparency.
Does anyone know what is going on?
There is a similar problem with ico file transparency, not always
is there some sort of test/fix utility?

I'm running Matlab 2010a on XP2000 (I know, I know, don't ask...).
When I do:

the y-axis is adjusted on saving. This becomes quite awkward when I want to re-format the y-axis, since my adjustments get messed up.
Any suggestions anyone?

...Using diff to compress multiple files
Is anyone aware of any software that compresses multiple files by
storing only the differences? Ideally it would analyse the files first
to work out which files were most similar to each other and pick the
best baseline file, compress that, and then just generate and compress
diffs to create the other files from either the baseline or from
another derived version. It would be ok if I had to tell it which
files could be efficiently created from others, but I'd like to be
able to extract any given file even if it required multiple diffs from
a baseline file to re-create it.

Several sites specify that the first 8 bytes of a valid PNG file must

If a test against the first 8 bytes and either of these two strings
fails, the PNG file is not valid.
I have two questions:
1) I read the first 8 bytes of the file into an array of 8 unsigned
chars. Using printf ("%x"), I can reproduce the hexadecimal string
above. However, I have tried every variant of printf ("%_"), to try and
create "\211PNG\r\n\032\n", but I cannot. Any ideas?

...PNG compression levels
I need to save some files a PNG. Never having used PNG
before, I'm a bit unsure about the meaning of compression
Is it true that PNG is completely lossless regardless of the
compression level, and that compression level only determines
how fast or slow a file will be to save and open? Is that
the only consideration for PNG compression levels?
