The FireMonkey built-in ImageFX engine provides over 50 GPU-powered effects. These effects are nonvisual components that can be found in the Effects category on the Tool Palette. All the provided effects can be simply enabled or disabled by setting the Enabled flag from the Form Designer, or programmatically.

Almost all the effects have specific properties that you can customize depending on the application. For example, all transition effects have the Progress property, which is used to set the amount of progress (in percentages, %) through the transition from the first texture to the second texture. The specified properties can be found in the Object Inspector when the effect is selected in the Structure View. All numeric properties of any effect can be animated to provide a gradual evolution in time. Image effects can also be triggered.

FireMonkey effects are built using shader filters. The shaders modify pixels, either individually or in concert with others, to achieve various visual effects. These effects are not limited to bitmap image data; effects can be applied to the pixels of any 2D control in the user interface. Effects can be used at run time or at design time to change the look of the application's user interface. The FireMonkey effects do not disable any controls or functionalities when they are applied.

For more information about applying a FireMonkey effect, see Applying FireMonkey Image Effects.

Kinds of Image Effects

The provided subclasses of TEffect fall into the categories listed in the following table. Each category is further described and illustrated later in this topic.

Effects that modify
pixels individually
Effects that consider
a pixel's neighbors

Effects that modify pixels individually

These effects typically apply changes to color. Each pixel's color can be considered on its own. The table below shows some of this kind of effect:

Effect Result Description Effect Result Description

None

InputBitmap.png

No effects applied.

TMonochromeEffect

Monochrome.png

Grayscale transformation.

TInvertEffect

Invert.png

Inverts the color of each pixel

TContrastEffect

Contrast.png

Adjusting contrast

THueAdjustEffect

HueAdjust.png

Adjusting hue

Fill effects

TFillRGBEffect or

TFillEffect

Fill.png

Color filling, either preserving alpha or completely overwriting.

Effects that consider a pixel's neighbors

This type of effect is applied using algorithms that use a pixel's neighbors to define the new value of the pixel. The table below shows some of this kind of effect:

Blur effects

Effect Result Description Effect Result Description

None

InputBitmap.png

TSwirlEffect and

TBandedSwirlEffect

Effects that modify the image as a whole

This kinds of effect applies geometric changes over the input image. The table below shows some of this kind of effect:

Effect Result Description Effect Result Description

None

InputBitmap.png

No effects applied.

TCropEffect

Crop.png

TAffineTransformEffect

Rotating.png

TPerspectiveTransformEffect

Perspective3D.png

TNormalBlendEffect

NormalBlend.png

Overlies two images. This work when the overlay has some transparency.

TTilerEffect

Tiler.png

Additive effects

This kind of effect affects the images by adding new elements to the original image. The elements can be added to the edges of the image or to the entire image. The table below shows some of this kind of effect:

Effect Opaque image Image with transparent areas Description

None

InputBitmap.png

TGlowEffect

Glow.png

FireMonkey logo TGlowEffect.PNG

|TInnerGlowEffect

InnerGlow.png

TShadowEffect

Shadow.png

FireMonkey logo TShadowEffect.PNG

TReflectionEffect

Reflection.png

FireMonkey logo TReflectionEffect.PNG

Transition effects

FireMonkey includes over twenty image transition effects, in which source pixels are progressively transformed into a target bitmap image, from simple fades to fancy banded swirls. The progress of the transformation is deterministic and can be set to an arbitrary percentage. This percentage can be animated to transition over time. To animate the progress of the transformation, see Apply an Animation Effect to a Property of an Image Effect.

The table below shows some animated transitions:

FireMonkey Image Sample Program

The ShaderFilters sample program demonstrates many of the FireMonkey image effects, except the additive effects and the basic stack blur.
