Canvas operation changes canvas size without changing image resolution. This operation can be used:
- to reduce image size by trimming or increase image size;
- to add margins to the image.
Add Canvas operation:
In the first case (“relative” flag is unchecked), specify desired image size in Width and Height textboxes. If current image size is larger than the desired image size, the image will be trimmed in accordance with the Anchor option. If current image size is smaller than desired image size, a border will be added to the image. The border color will be that specified in “Border color” option.
In the second case (“relative” flag is checked) Width and Height boxes should contain the number of pixels to be added to image sides, image top and image bottom. Margins will be added to sides not specified in Anchor option. For example, if Center alignment is selected, margins will be added to all image sides. If Bottom Left alignment is selected, margins will be added to the top and right sides of the image. The color of margins will be that specified in “Border color” option.
Anchor option is used to specify image alignment for operations described above. Use this option to align the image by any side or corner of the canvas.
Border color option is used to specify the color of empty margin. Available values are transparency, black color, white color. If any other color is needed, select User defined line and choose the needed color from the dialog box that appears.
