<term>BackPixmap <emphasis remap='I'>type</emphasis> <emphasis remap='I'>pixmap_name|color_name</emphasis></term>
      <listitem>
<para>Specifies that a pixmap should be used as a background instead of a
solid color. This option has two forms, depending on the value of <emphasis remap='I'>type</emphasis> :
</para> 
<para>
If <emphasis remap='I'>type</emphasis> is 125, 126, 127, 128, 130-144, 150-164
- the second parameter, <emphasis remap='I'>pixmap_name</emphasis>
must be the name of an image file which can be found in <emphasis remap='I'>PixmapPath</emphasis>. 
</para> 
<para>
If <emphasis remap='I'>type</emphasis> is 129 or 149 the root pixmap (desktop
background) will be used, and the optional second parameter must be a
color with which the root pixmap will be shaded/tinted.  
</para> 
<para>
Depending on the value of <emphasis remap='I'>type</emphasis> AfterStep will render pixmap in many different ways :

<variablelist>
<varlistentry><term>125</term><listitem>
Image is SCALED to the size of the widget, and its opacity is used to set the shape of the widget/window decoration, 
achieving non-rectangular window effect.
</listitem></varlistentry>
<varlistentry><term>126</term><listitem>
Image is TILED to the size of the widget, and its opacity is used to set the shape of the widget/window decoration, 
achieving non-rectangular window effect.
</listitem></varlistentry>
<varlistentry><term>127</term><listitem>
Image is SCALED to the size of the widget.
</listitem></varlistentry>
<varlistentry><term>128</term><listitem>
Image is Tiled to the size of the image.
</listitem></varlistentry>
<varlistentry><term>129</term><listitem>
Underlying desktop background is tinted/shaded with the color specified with the second parameter.
</listitem></varlistentry>
<varlistentry><term>130</term><listitem>
Underlying desktop background is combined with tiled image, using "allanon" method - taking average of pixel values.
</listitem></varlistentry>
<varlistentry><term>131</term><listitem>
Underlying desktop background is alpha-blended with tiled image.
</listitem></varlistentry>
<varlistentry><term>132</term><listitem>
Underlying desktop background is tinted using pixel values of the tiled image, as a tint values on per-pixel basis.
</listitem></varlistentry>
<varlistentry><term>133</term><listitem>
Each pixel of underlying desktop background has value of tiled image's pixel added to it.
</listitem></varlistentry>
<varlistentry><term>134</term><listitem>
Each pixel of underlying desktop background has value of tiled image's pixel subtracted from it.
</listitem></varlistentry>
<varlistentry><term>135</term><listitem>
Result consists of pixels representing absolute value of difference between underlying desktop background and tiled image.
</listitem></varlistentry>
<varlistentry><term>136</term><listitem>
Underlying desktop background is darkened using luminocity of the tiled image's pixels.
</listitem></varlistentry>
<varlistentry><term>137</term><listitem>
Underlying desktop background is lightened using luminocity of the tiled image's pixels.
</listitem></varlistentry>
<varlistentry><term>138</term><listitem>
Underlying desktop background is "screened" by the tiled image.
</listitem></varlistentry>
<varlistentry><term>139</term><listitem>
Underlying desktop background is "overlayed" by the tiled image.
</listitem></varlistentry>
<varlistentry><term>140</term><listitem>
Underlying desktop background's hue is substituted with the hue of the tiled image.
</listitem></varlistentry>
<varlistentry><term>141</term><listitem>
Underlying desktop background's saturation is substituted with the saturation of the tiled image.
</listitem></varlistentry>
<varlistentry><term>142</term><listitem>
Underlying desktop background's value (in HSV colorspace) is substituted with the value of the tiled image.
</listitem></varlistentry>
<varlistentry><term>143</term><listitem>
Underlying desktop background is "colorized" by the tiled image.
</listitem></varlistentry>
<varlistentry><term>144</term><listitem>
Underlying desktop background is "dissipated" by the tiled image.
</listitem></varlistentry>

<varlistentry><term>149</term><listitem>
Underlying desktop background is tinted/shaded with the color specified with the second parameter.
It differs from 129 so that desktop background could be both darkened and brightened. If tint color
channel is greater the 7F (127 decimal) - then respective channel of background will be brightened.
</listitem></varlistentry>

<varlistentry><term>150 - 164</term><listitem>
Same as 130-144 but specified image is scaled to the size of the widget.
