Method Detail

setAlign

public void setAlign(javax.el.ValueExpression __align)

Deprecated. This attribute specifies the position of an IMG, OBJECT, or APPLET with respect to its context. The possible values are "bottom", "middle", "top", "left" and "right". The default value is "middle". Setter for align

Parameters:

align - - new value

setAlt

public void setAlt(javax.el.ValueExpression __alt)

For compability with XHTML 1.1 standart Setter for alt

Parameters:

alt - - new value

setBgcolor

public void setBgcolor(javax.el.ValueExpression __bgcolor)

Background color of painted image. Default value is 'transparent' which means no background fill. Hex colors can be used, as well as common color names. Invalid values are treated as transparent. Note, that JPEG format doesn't support transparency, and transparent background is painted black. Also note, that several browsers (e.g. IE6) do not support PNG transparency. Default value is "transparent" Setter for bgcolor

Parameters:

bgcolor - - new value

setBorder

public void setBorder(javax.el.ValueExpression __border)

Deprecated. This attribute specifies the width of an IMG or OBJECT border, in pixels. The default value for this attribute depends on the user agent Setter for border

Parameters:

border - - new value

setCacheable

public void setCacheable(javax.el.ValueExpression __cacheable)

Supported (or not) client/server caching for generated images. Caching on client supported by properly sending and processing of HTTP headers (Last-Modified, Expires, If-Modified-Since, etc.) Server-side caching is supported by application-scope object cache. For build of cache key use "value" attribute, serialized to URI Setter for cacheable

Parameters:

cacheable - - new value

setData

public void setData(javax.el.ValueExpression __data)

Value calculated at render time and stored in Image URI (as part of cache Key), at paint time passed to a paint method. It can be used for updating cache at change of image generating conditions, and for creating paint beans as "Lightweight" pattern components (request scope). IMPORTANT: Since serialized data stored in URI, avoid using big objects Setter for data

Parameters:

data - - new value

setFormat

public void setFormat(javax.el.ValueExpression __format)

format Name of format for sending a generated image. It currently supports "jpeg" (24 bit, default), "gif" (8 bit with transparency), "png" (32 bit with transparency) Setter for format

Parameters:

format - - new value

setHeight

public void setHeight(javax.el.ValueExpression __height)

Height in pixels of image (for paint canvas and HTML attribute). Default value is "10". Setter for height

Parameters:

height - - new value

setHspace

public void setHspace(javax.el.ValueExpression __hspace)

Deprecated. This attribute specifies the amount of white space to be inserted to the left and right of an IMG, APPLET, or OBJECT. The default value is not specified, but is generally a small, non-zero length Setter for hspace

Parameters:

hspace - - new value

setPaint

public void setPaint(javax.el.MethodExpression __paint)

The method calls expression to paint Image on prepared Buffered image. It must have two parameters with a type of java.awt.Graphics2D (graphics to paint) and Object (restored from URI "data" property). For painting used 32-bit RGBA color model (for 8-bit images used Diffusion filtration before sending) Setter for paint

Parameters:

paint - - new value

setValue

public void setValue(javax.el.ValueExpression __value)

The current value of this component Setter for value

Parameters:

value - - new value

setVspace

public void setVspace(javax.el.ValueExpression __vspace)

Deprecated. This attribute specifies the amount of white space to be inserted above and below an IMG, APPLET, or OBJECT. The default value is not specified, but is generally a small, non-zero length Setter for vspace

Parameters:

vspace - - new value

setWidth

public void setWidth(javax.el.ValueExpression __width)

Width in pixels of image (for paint canvas and HTML attribute). Default value is "10". Setter for width

Parameters:

width - - new value

Overrides:

setProperties in class org.ajax4jsf.webapp.taglib.HtmlComponentTagBase
