4.4 Object filters dialog

This dialog can be used to apply filter effects like transparency, tinting, shadow, or border to layers. The object filters dialog is a modeless dialog and can thus be kept always open, just like the object manager, page manager, and layout dialogs.

For each filter you can specify a priority setting. This setting is only used in case multiple filters are active for the current object. In that case, the priority setting specifies the order in which Hollywood Designer applies the filters to the layer. For example, if you assign priority "+1" to the 'Invert' filter, and priority "Normal" to the 'Solarize' filter then Hollywood Designer will first invert the layer, and then apply the solarization effect.

The following filters are currently supported:

‘Blur’

This filter will apply a Gaussian blur to the layer. The following parameters are supported:

Radius:

Specifies the blur radius. The greater the value you specify here, the longer the blurring will take.

‘Border’

This filter will apply a border to the layer. The following parameters are supported:

Color:

Desired border color.

Size:

Desired border size.

‘Charcoal’

This filter will apply a charcoal filter to the layer. The following parameters are supported:

Radius:

Specifies the effect radius. The greater the value you specify here, the longer the calculation will take.

‘Contrast decrease’

‘Contrast increase’

This filter will enhance/reduce the color contrast in the layer. The following parameters are supported:

Level:

Specifies how many times the effect should be repeated. This is useful for a more pronounced effect. By default this is set to 1 which means that the effect is only applied once. If you would like to have two passes, specify 2 here, etc. Remember that the greater the number you specify here is, the longer the computation of the result will take.

‘Edge’

This filter will apply an edge detection filter to the layer. The following parameters are supported:

Radius:

Specifies the effect radius. The greater the value you specify here, the longer the calculation will take.

‘Emboss’

This filter will apply an emboss filter to the layer. The following parameters are supported:

Radius:

Specifies the effect radius. The greater the value you specify here, the longer the calculation will take.

‘Gamma’

This filter can be used to apply gamma correction to the layer. The following parameters are supported:

Red:

Gamma correction for red color channel.

Green:

Gamma correction for green color channel.

Blue:

Gamma correction for blue color channel.

Each value must be percentage. A value of 100% means no change, a value smaller than 100% darkens the channel, a value greater than 100% lightens it.

‘Grayscale’

This filter will map the layer to gray. There are no parameters for this filter.

‘Invert’

This filter will invert the colors of the layer. There are no parameters for this filter.

‘Modulate’

This filter can be used to modulate brightness, saturation, and hue values of a layer. The following parameters are supported:

Brightness:

Desired brightness modulation.

Saturation:

Desired saturation modulation.

Hue:

Desired hue modulation.

Each value must be percentage specification. A value of 100% means no change, a value smaller than 100% reduces the brightness/ saturation/hue, while a value greater than 100% enhances it.

‘Monochrome’

This filter will apply a black and white filter to this layer. The following parameters are supported:

Dither:

Specifies whether or not dithering should be used.

‘OilPaint’

This filter will apply an oil paint filter to the layer. The following parameters are supported:

Radius:

Specifies the effect radius. The greater the value you specify here, the longer the calculation will take.

‘Pixelate’

This filter will zoom the pixel cells of the layer to the specified size. The following parameters are supported:

CellSize:

Specifies the desired zoom size. Every pixel of the layer will be zoomed to this size, starting from the top-left corner of the layer.

‘Quantize’

This filter will reduce the number of colors in the layer and apply optional dithering. The following parameters are supported:

Number of colors:

Specifies the desired number of colors for the layer.

Dither:

Specifies whether or not dithering should be used.

‘SepiaTone’

Applies a sepia-tone filter to the layer. The following parameters are supported:

Level:

Desired sepia-toning level. The usual setting is "80%".

‘Shadow’

Applies a drop shadow to the layer. The following parameters are supported:

Color:

Desired color for the shadow.

Direction:

Desired direction for the shadow.

Position:

Shadow offset from the main layer.

Smooth radius:

Smoothing level for shadow.

Transparency:

Transparency level of shadow.

‘Sharpen’

Applies a sharpening filter to the layer. The following parameters are supported:

Radius:

Specifies the sharpen radius. The greater the value you specify here, the longer the calculation will take.

‘Solarize’

Applies a solarization effect to the layer. The following parameters are supported:

Level:

Desired solarization level in percent.

‘Swirl’

Swirls the layer by the specified number of degrees. The following parameters are supported:

Degrees:

Specifies the desired swirling amount. This can be between 0 (no swirling) and 360 (full swirl).

‘Tint’

This filter will tint the layer with the specified color at the specified ratio. The following parameters are supported:

Color:

Specifies the tinting color.

Level:

Specifies the tinting ratio. This can be a value between 0% (= no tinting) and 100% (= full tinting).

‘Transparency’

This filter allows you to specify a transparency level for this layer. The following parameters are supported:

Level:

Transparency level of this layer. 0% means no transparency, 100% means full transparency.

‘Water ripple’

This filter will apply water ripples to the layer. The following parameters are supported:

Length:

Desired wavelength for the effect.

Amplitude:

Desired ripple amplitude.

Phase:

Desired ripple phase.

Center X:

X center point of water ripple.

Center Y:

Y center point of water ripple.

‘X Flip’

This will mirror the layer on the x-axis. There are no parameters for this filter.

‘Y Flip’

This will mirror the layer on the y-axis. There are no parameters for this filter.
