9.1 Input

9.1.1 Gradient

The Gradient node produces an image filled with a gradient. A gradient is a gradual change between different colors. Its output is most often used for a variety of blending operations such as a background, mask, overlay or simulating a vignette.

Input

Size
The size of the canvas. Select “Match” to copy an input image’s size. Select “Custom” to manually enter a size in pixels.
Image (If Size is set to “Match”)
The size of the output image. The color profile of the output image is also copied from this image.
Color Profile (If Size is set to “Custom”)
Color profile assigned to the output image. A color transformation is only performed if Color Interpolation is set to “CIE LCh.”
Shape

The geometric representation of the gradient.

  • Linear: Two lines with the gradient filling the middle between them.
  • Radial: An ellipse filled with the gradient.
Color Interpolation

The color model used when interpolating.

  • RGB: Typical red, green, and blue color model.
  • CIE LCh: A color space where colors are perceptionally uniform which means changes in lightness and saturation appear consistent during interpolation.
Curve

How the gradient should be mapped.

  • Linear: Smoothly change from one color to the next.
  • Custom: Specify exactly how the gradient goes from one color to the next using a curve. The curve editor functions similarly to the curve editor in the Curves node.
Gradient
The gradient used to fill the image. Stops, colors at offsets in the gradient, can be added by left clicking anywhere on the bar. A stop can be moved by left clicking and dragging its arrow. A stop can be deleted by left clicking its arrow to select it and then pressing the Delete key or by right clicking and selecting “Delete Stop” in the pop-up menu. The color of a stop can be changed by holding the shift key and left clicking its arrow or by right-clicking and selecting “Set Color” in the pop-up menu. The first stop on the far left and the last stop on the far right cannot be moved or deleted.

Output

Image
An image filled with the gradient.

Mode

The gradient can be positioned by left clicking and dragging one of the large circular handles over the canvas. You can hold shift while dragging to snap the gradient to an angle in 15 degree increments. A stop can be inserted by double clicking between the end stops. The mid stops can also be repositioned by left clicking and dragging. You can change the color of the selected stops using the color picker on the right. To select a stop, left click it and its outline will turn yellow to indicate that it has been selected. Selected stops can be deleted by pressing the Delete key.

The radial gradient’s focal point can be moved by left clicking and dragging the arrows which are by default located around the center circular handle. The focal point is where the first stop in a radial gradient is placed. The remaining stops are interpolated out towards the edge.

9.1.2 Image Open

The Image Open node is used to import JPEG, PNG, and TIFF files. A copy of the imported file is stored internally. If the file is modified outside of Phoduit, it must be re-imported. Only one image can be imported per Image Open node. To import more than one image, add additional Image Open nodes.

Input

Color Profile
The color profile that the imported image should be converted to. Select “Embedded” to not perform any color conversion. If the imported image does not have any color information, it’s considered as sRGB.
Select Image File
Click to select the JPEG, PNG, or TIFF file you want to import. If another image file has already been imported, it will be replaced.

Output

Image
The image that was imported.

Mode

Displays various meta data about the imported image in the Meta Info dock window.

9.1.3 Paint Canvas

The Paint Canvas node provides an image that can be painted. It’s often used to build masks when working with the Blend node.

Input

Size
The size of the canvas. Select “Match” to copy an input image’s size. Select “Custom” to manually enter a size in pixels.
Image (If Size is set to “Match”)
The size of the output image. The color profile of the output image is also copied from this image.
Width (If Size is set to “Custom”)
Width in pixels of the output image.
Height (If Size is set to “Custom”)
Height in pixels of the output image.
Color Profile (If Size is set to “Custom”)
Color profile assigned to the output image. Note: No color transformation will be performed.

Output

Image
The image as edited. See Mode below for editing details.

Mode

There are three tools available to interact with the Paint Canvas node.

Icon Name Keyboard Shortcut Description

Brush

B

Left click and drag your cursor over the Canvas to paint. Use the Brush dock window to change the brush size, opacity, and hardness. Use the Color dock window to change the color.

Eraser

D

Left click and drag your cursor over the Canvas to clear alpha. Use the Brush dock window to change the brush size, opacity, and hardness.

Eye Dropper

E

Left click your cursor over the Canvas to change the selected brush color to the color under your cursor.

All of these tools are transform aware.

If the output size is made smaller, the clipped areas are saved in case you decide to make it larger later. When this happens, the indicator is displayed on the status bar. If you’re sure you want to get rid of these clipped areas, you can save some memory by clicking the indicator to delete them. If you click the indicator by accident, you can left click the Edit menu at the top of the Main Window and then left click Undo.

9.1.4 Raw Image Open

The Raw Image Open node is used for importing raw image files. A copy of the imported file is stored internally. If the file is modified outside of Phoduit, it must be re-imported. Only one image can be imported per Raw Image Open node. To import more than one image, add additional Raw Image Open nodes.

Raw images are imported with absolutely minimal processing (usually just a conversion to 16-bits). Most raw images will require at least color correction and demosaicing. See Chapter 7. Raw Images for a step-by-step walkthrough on working with raw images.

Input

Color Profile
The color profile the imported image is converted to. Select “Embedded” to not perform any color conversion. If the imported image does not have any color information, it’s considered as linear sRGB.
Select Image File
Click to select the raw image file you want to import. If another raw image file has already been imported, it will be replaced.

Output

Image
The image that was imported.

Mode

Displays various meta data about the imported image in the Meta Info dock window.

9.1.5 Solid Color

The Solid Color node produces an image made entirely of a single color.

Input

Size
The size of the canvas. Select “Match” to copy an input image’s size. Select “Custom” to manually enter a size in pixels.
Image (If Size is set to “Match”)
The size of the output image. The color profile of the output image is also copied from this image.
Width (If Size is set to “Custom”)
Width in pixels of the output image.
Height (If Size is set to “Custom”)
Height in pixels of the output image.
Color Profile (If Size is set to “Custom”)
Color profile assigned to the output image. Note: No color transformation will be performed.
Color
Color and alpha used to fill the entire output image. Alpha is the transparency which is usually used for compositing with the Blend node.

Output

Image
An image filled completely with the specified color.
