You can use several methods to resize or scale paint objects and the images they contain.
Keep in mind that altering the size or resolution of a paint object can degrade the quality of an image. Canvas X Draw uses interpolation to estimate pixel values when necessary, but this can result in loss of sharpness or detail when large scaling factors are applied.
The best way to avoid image degradation is to avoid changing image size or resolution.
You can also remove effects via the Undos palette or by using the keyboard command: Ctrl+Z.
You can change the size of a paint object by clicking on it with the Selection tool and dragging a selection handle. Stretching an image non-proportionately also stretches the pixels, which can cause unwanted distortion to the image.
Change the size of a paint object by selecting it and choosing Object | Scale. The Scale command lets you maintain the object’s proportions or distort an image by scaling it in one direction. Using the Scale command does not add or remove pixels from an image. For information on using Scale, see Scaling Objects.
Use the Crop command to adjust the overall size of an image.
Canvas X Draw features a Crop & Scale menu that you can easily access via the Properties bar when an image object is selected.
When you choose a cropping size from the Crop & Scale menu and apply it to a selected image, a cropping rectangle appears on the image, just as if you were using the Crop tool. Click inside this rectangle and Canvas crops your image.
Apply a cropping size from the Crop & Scale menu to a selected image and various cropping options appear in the Properties bar.
You can identify whether you are in Edit mode by the Status bar or the following icon in the Properties bar:
Width and height of cropping rectangle in pixels.
Width and height of cropping rectangle in current ruler units.
Select either radio button to perform a permanent or temporary crop. The cropped image is not scaled with these options.
Crop & Scale
Select this radio button to permanently crop and scale an image. After cropping, the image is scaled proportionally. With the Crop & Scale option, you can also define the DPI of the image by entering a value in the New DPI field.
The center of the cropping rectangle is indicated by a square icon.
The Trim command lets you remove same-color pixels that are near the edge of the image area. This feature is useful for removing unwanted white space or other borders that are not part of the main image, e.g., you scan a photo that doesn’t fill the entire scanner area, and there is a white border around the photo. The Trim command identifies the edges of the image, determines which pixels around the border match, and deletes the unwanted border.
Canvas X Draw alerts you if the image can’t be trimmed because a border can’t be found.
The Trim to Path command lets you trim an image with a vector or text object. Unlike a clipping path, which “hides” anything outside the path, the Trim to Path command deletes any part of the image that is outside the path. The result is a single image object, rather than an image and vector object as is the case with clipping paths. (See Using Clipping Paths.)
The trimming object cannot be larger than the image. If a part of the path doesn’t touch the image, an error occurs.
You can even use special objects, such as Concentric Circles, Spirals, Multigons, and Cubes to trim an image.
We want to create a uniquely shaped image from this original photo.
In this example, a heart-shaped Bézier curve is used as a trimming object. Place the trimming object in front of the image. Select both objects and choose Image | Trim to Path.
The result is a single heart-shaped image.
Use the Crop tool to select a rectangular part of an image and hide the rest, which is called a “soft crop.” When you edit a soft-cropped image, the cropped area reappears while the image is in Edit mode. When you finish editing, Canvas X Draw re-crops the image.
You can also use the Crop tool to “hard-crop” an image, which adds or removes pixels, as an alternative to using the Area | Crop command.
Soft crop pointer indicates cropping will be temporary.
Hard crop pointer indicates cropping will be permanent.
A gavel appears in crop mode when the pointer is in the image. Click to complete the crop.
A hand appears in crop mode when you point to a side of the cropping rectangle. Drag to move the rectangle.
This symbol appears if the pointer is outside the image in crop mode.
Adjust the cropping rectangle with the Crop tool by dragging a handle. Enclose the area you want to keep, and then press Esc to hide the cropped part of the image.
In hard-crop mode, the Crop tool discards pixels that are outside the cropping rectangle.
Quickly crop or expand a paint object using the Selection tool. Select the paint object (don’t put it in Edit mode), then Ctrl-drag a handle to crop or add pixels to the image. When you drag, the cropping rectangle and handles appear. When you release the mouse, Canvas X Draw applies a hard crop.
If the paint object you crop is an Indexed mode object, the color of the added pixels is the last color in the color table associated with the image, which often is black.
When you press a modifier key and click with the Crop tool, you can expand a paint object. This adds a white border to an RGB Color or CMYK Color image.
