Changes:

I was a little hasty on that last update. A couple new bugs from 1.1.0 have
|
2013-04-16 21:24:50 +02:00
|
|
|
been fixed.

Version 1.1.0:
|
|
|
|
|
Date: 2009-03-16
|
|
|
|
|
|
|
|
|
|
Changes:
|
2013-04-16 21:24:50 +02:00
|
|
|
Added Vista support.
|
2013-04-16 21:22:32 +02:00
|
|
|
Fixed a number of minor bugs. Many thanks to Dvir Berebi for pointing
|
|
|
|
|
them out.
|
|
|
|
|
|
|
|
|
|
Version 1.0.5:
|
|
|
|
|
Date: 2009-03-15
|
|
|
|
|
|
|
|
|
|
Changes:
|
|
|
|
|
Fixed bug when operating on low bit count images (1 or 4) with odd dimensions.
|
|
|
|
|
|
|
|
|
|
Version 1.0.4:
|
|
|
|
|
Date: 2007-05-25
|
|
|
|
|
|
|
|
|
|
Changes:
|
|
|
|
|
Made function not break quite so bad when reading a PNG file on a Vista icon.
|
|
|
|
|
Now, you shouldn't be loading Vista icons anyways, but since I'm trying to
|
|
|
|
|
upgrade to Vista compatible and I need a comparison, I've got to.
|
|
|
|
|
|
|
|
|
|
Version 1.0.3:
|
|
|
|
|
Date: 2007-05-25
|
|
|
|
|
|
|
|
|
|
Changes:
|
|
|
|
|
Okay, this one was just stupid. When adding large image support, I messed up
|
|
|
|
|
and when reading, it doubled the image size. Now, it's fixed.
|
|
|
|
|
I took the opportunity to also add a dummy AND map for 32 images on those
|
|
|
|
|
readers who might be looking for it (though it's not supposed to be used.)
|
|
|
|
|
|
|
|
|
|
Version 1.0.2:
|
|
|
|
|
Date: 2007-05-24
|
|
|
|
|
|
|
|
|
|
Sorry about two versions so quickly back to back, but something needed to be
|
|
|
|
|
done with speed...things were getting too slow. I'm sure you'll be okay.
|
|
|
|
|
|
|
|
|
|
Changes:
|
|
|
|
|
Told palette determination to stop at 257 colors or is 32 bit because the
|
|
|
|
|
palette is not used at that point and gets really slow when it starts
|
|
|
|
|
getting into the high numbers, for instance, in photographs or gradient
|
|
|
|
|
truecolor images with lots of unique colors.
|
|
|
|
|
After experimenting, it appears that Windows XP does in fact support 256x256
|
|
|
|
|
images and larger by setting the entry value to 0 in the 1 byte that holds
|
|
|
|
|
that value and storing the true dimentions in the image header later. Of
|
|
|
|
|
course, it still doesn't use these images in normal operation. XP will
|
|
|
|
|
resize these and use them if no other images are available.
|
|
|
|
|
Wrapped main documentation (this) to the 80th column for easier reading.

Thank you everyone for actively using the implementation on my site and
|
|
|
|
|
illuminating me very quickly to a number of glaring bugs in this class.
|
|
|
|
|
|
|
|
|
|
Changes:
|
|
|
|
|
Added version history.
|
|
|
|
|
Fixed bug with non-standard sizes in AND map reading AND writing.
|
|
|
|
|
Fixed bug with palette images using non-black color in backgrounds.
|
|
|
|
|

Foreword:
|
|
|
|
|
If you are simply in the effort of making an ICO file, may I recommend visiting
|
|
|
|
|
my site, http://www.flobi.com/ , and clicking on floIcon. I have a fully
|
|
|
|
|
functional implementation (on which the sample.php is based) where you can also
|
|
|
|
|
see recent icons submitted by other visitors. No registration required, no
|
|
|
|
|
intrusive ads. (As of this writing, there aren't actually any ads at all, I
|
|
|
|
|
might add google ads at some point.)
|
|
|
|
|
|
|
|
|
|
If you are trying to get an idea of how ICO files, work, may I recommend the
|
|
|
|
|
page I used, http://www.daubnet.com/formats/ICO.html . It does not fully cover
|
|
|
|
|
icon files, but it does a very good job of what it does. Any additional
|
|
|
|
|
information, I will try to post at
|
|
|
|
|
http://www.flobi.com/test/floIcon/more_on_icons.php for your convenience.
|
|
|
|
|
|
|
|
|
|
If you are trying to get an idea of how image resource files work, I recommend
|
|
|
|
|
ANY other class that deals with images. This class essentially plots points on
|
|
|
|
|
the image, and that's not perticularly advanced.
|
|
|
|
|
|
|
|
|
|
For any purpose, I wish you luck and feel free to contact me with any bugs,
|
|
|
|
|
comments, questions, etc. - Flobi
|
|
|

|
|
Summary:
|
|
|
|
|
This class parses ICO files. It reads directly from the ICO file, headers
|
|
|
|
|
first, so that if you are only retrieving 1 image, the entire ICO file need not
|
|
|
|
|
be parsed. It supports merging ICO files. It supports adding PHP image
|
|
|
|
|
resources as new images to the file. It has an export capability that can
|
|
|
|
|
easily be written to a new (or the same) ICO file for saving ICO files. All
|
|
|
|
|
sizes from 1x1 to 255x255 pixels and 1, 4, 8, 24 (plus transparency) and 32 bit
|
|
|
|
|
images are supported. Image retrieval by size is supported.
|
|
|
|
|
|
|
|
|
|
Included is a fully functional sample that allows users to upload ICO, GIF,
|
|
|
|
|
JPEG and PNG files into a session icon file as well as remove images from the
|
|
|
|
|
file and download the completed file (sample.php).
|
|
|
|
|
|
|
|
|
|
Known Limitations: Does not support Vista icons. Does not support inversion
|
|
|
|
|
palette method (because of the limitations of the PHP image resource).
|
|
|
|
|
|
|
|
|
|
Addendum on Limitations:
|
|
|
|
|
Windows Vista has added support for 256x256 size icons and now stores files as
|
|
|
|
|
PNG's. This class is for older ICO files. A new class is currently under
|
|
|
|
|
development that supports the new Windows Vista format.
|
|
|
|
|
|
|
|
|
|
Palette inversion (my name for this technique) is the technique of using a black
|
|
|
|
|
pixel (0, 0, 0) with a 1 "AND" pixel. White pixels with a 1 "AND" show
|
|
|
|
|
transparent (or "don't" show). Black pixels with a 1 "AND" show inverted
|
|
|
|
|
(sometimes). Because this method isn't uniformly supported or documented and
|
|
|
|
|
the PHP image resource doesn't support it, I have decided to not as well. This
|
|
|
|
|
does not apply to 32 bit images which include alpha transparency and no AND map.
|
|
|
|
|
|
|
|
|
|
Though other functions exist, these are the only ones I believe offer usefulness
|
|
|
|
|
to be public.
|
|
|
|
|
floIcon public functions:
|
|
|
|
|
readICO($file, $offset = 0)
|
|
|
|
|
Loads the icon from the specified filepath ($file) starting at the
|
|
|
|
|
specified file offset ($offset). This function MERGES the loaded icon
|
|
|
|
|
images into the floIcon object.
|
|
|
|
|
|
|
|
|
|
formatICO($offset = 0)
|
|
|
|
|
Returns the current floIcon object formatted as an .ICO file with the
|
|
|
|
|
file offset altered by $offset. If there are too many or too large
|
|
|
|
|
images, causing any images saved past the 4,294,967,296th byte, this
|
|
|
|
|
will return false. (This is well outside PHP's default memory
|
|
|
|
|
allocation.)
|
|
|
|
|
|
|
|
|
|
addImage($imageResource, $desiredBitCount = 1, $pngIfWidthExceeds = 48)
|
|
|
|
|
Adds an icon image to the icon file based on the passed image resource
|
|
|
|
|
($imageResource). It will automatically determine the bit count, but
|
|
|
|
|
can be persuaded to increase that to $desiredBitCount if that value is
|
|
|
|
|
greater than the determined bit count.
|
|
|
|
|
|
|
|
|
|
NOTE: The image resource is saved by REFERRENCE. So, if you edit it
|
|
|
|
|
then call getImage, the resource returned will be the same, editions and
|
|
|
|
|
all. Destruction of the resource will cause a new resource to be
|
|
|
|
|
created in getImage().
|
|
|
|
|
|
|
|
|
|
getImage($offset)
|
|
|
|
|
Returns the php image resource either assigned by addImage or created
|
|
|
|
|
dynamically at calltime by the data loaded with readICO(). The offset
|
|
|
|
|
specified here ($offset) is the array offset starting at 0 and ending
|
|
|
|
|
at countImages().
|
|
|
|
|
|
|
|
|
|
getBestImage($height = 32, $width = 32)
|
|
|
|
|
Returns the php images resource of the highest quality image closest to
|
|
|
|
|
the size specified. This could be useful when you only want to display
|
|
|
|
|
the icon in an icon list with a single representative icon. A resized
|
|
|
|
|
copy of the highest quality available image will be returned if there is
|
|
|
|
|
no 32 or 24 bit icon present at the speficied dimentions.
|
|
|
|
|
|
|
|
|
|
sortImagesBySize()
|
|
|
|
|
Sorts the $this->images array by order of size, smallest to largest.
|
|
|
|
|
This is the optimal sorting for icon files.
|
|
|
|
|
|
|
|
|
|
countImages()
|
|
|
|
|
Returns a count of how many images are present in the current floIcon
|
|
|
|
|
object.
|
|
|
|
|
|
|
|
|
|
floIcon public variables:
|
|
|
|
|
$images
|
|
|
|
|
Contains a numerically indexed array of floIconImage objects.
|
|
|
|
|
$updated
|
|
|
|
|
True if an image has been added since load or last formatICO, otherwise
|
|
|
|
|
false.
|
|
|
|
|
|
|
|
|
|
floIconImage public functions:
|
|
|
|
|
getHeader()
|
|
|
|
|
Returns an associative array containing the information from the ICO
|
|
|
|
|
image header.
|
|
|
|
|
|
|
|
|
|
getEntry()
|
|
|
|
|
Returns an associative array containing the information from the ICO
|
|
|
|
|
entry header.
|
|
|
|
|
|
|
|
|
|
NOTE: If this icon image was created by php image resource, this may not
|
|
|
|
|
have accurate information until saving from floIcon with the formatICO()
|
|
|
|
|
function. Specifically, offset information will be inaccurate.
|
|
|
|
|
|
|
|
|
|
getImageResource()
|
|
|
|
|
Returns a php image resource. Same as floIcon's getImage() function.
|
|
|
|
|
|
|
|
|
|
setImageResource($imageResource, $desiredBitCount = 1, $pngIfWidthExceeds = 48)
|
|
|
|
|
Changes this icon image based on the passed image resource
|
|
|
|
|
($imageResource). It will automatically determine the bit count, but can
|
|
|
|
|
be persuaded to increase that to $desiredBitCount if that value is
|
|
|
|
|
greater than the determined bit count.
|
|
|
|
|
|
|
|
|
|
NOTE: The image resource is saved by REFERRENCE. So, if you edit it
|
|
|
|
|
then call getImageResource, the resource returned will be the same,
|
|
|
|
|
editions and all. Destruction of the resource will cause a new resource
|
|
|
|
|
to be created in getImageResource().
|
|
|
|
|
|
|
|
|
|
dealocateResource()
|
|
|
|
|
This destroys the image resource variable, freeing up memory. The image
|
|
|
|
|
will automatically be recreated when getImageResource is executed.
