nothing setGdFunctionality(
&$obj
)
|
|
Set a different GdFunctionality object to be used by this Toolkit.
This is useful on our phpunit tests, which will make this Toolkit use a pseudo-gd-implementation that simulates different PHP versions.
Parameters:
bool _canHaveAlphaChannel(
string
$mimeType
)
|
|
Checks whether files of the given mime-type can have a whole alpha channel.
Parameters:
bool _canHaveTransparency(
string
$mimeType, [resource
$res = null]
)
|
|
Checks whether files of the given mime-type can have transparencies.
Parameters:
|
string |
$mimeType: |
|
|
resource |
$res: |
(optional) If specified, additional checks are executed |
GalleryStatus _flattenAlphaChannel(
resource
$res, string
$outputMimeType
)
|
|
Handle the resouce according to the capabilities of the output format.
- For formats that support an alpha channel, don't do anything.
- For formats that support a single transparent color, interpret everything that is more
than 50% opaque as transparent.
- For formats that don't support any form of transparency, fill the transparent area
with a predefined background color.
The code is based on phpthumb by James Heinrich <info@silisoftware.com>.
Parameters:
|
resource |
$res: |
|
|
string |
$outputMimeType: |
|
Parameters:

array _getImageResource(
string
$mimeType, string
$filename
)
|
|
Return a GD image resource for the given filename so we can perform other operations on it.
Parameters:
|
string |
$mimeType: |

array _getTrueColorImageRes(
int
$width, int
$height, [bool
$prepareAlpha = false]
)
|
|
Create a truecolor GD resource with the specified sizes.
On GD >= 2.0.1 there is a function to do this directly. On earlier versions, we need to create a temporary JPEG image and create the image from that.
Parameters:
|
int |
$width: |
|
|
int |
$height: |
|
|
bool |
$prepareAlpha: |
(optional) whether the resource should be prepared to host any transparencies |

$srcX,
$srcY,
$dstW,
$dstH,
$srcW,
$srcH
)
|
|
Copy and resize part of an image with resampling or resizing.
We will use GD's "resample" functionality and fallback to "resize" if "resample" is not available.
Parameters:
