CorelDRAW: Implementing with bitmaps

We can transform any vector graphics into the bitmap. In CorelDRAW, we can also crop and import bitmaps. Also, we can insert special effects, watermarks, and color masks, and modify the tone and color of an image.

This chapter includes the following essential topics:

  • Transforming vector graphics into bitmaps
  • Cropping bitmaps
  • Changing the bitmap's resolution and dimensions
  • Straightening bitmaps
  • Removing scratch and dust marks from a bitmap
  • Using special effects
  • Bitmap colors
  • Image adjustment lab usage
  • Adjusting the tone and color
  • Transforming tone and color

Transforming vector graphics into bitmaps

Transforming vector graphics into bitmaps allows us to use some special effects on the objects in CorelDRAW. The vector graphics transforming process into bitmaps can also be referred to as "rasterizing."

To transforming vector graphics into bitmaps

1. Choose the object.

2. Press Bitmaps > Covert to bitmap.

3. Select any resolution from the list box of Resolution.

4. Select any color mode from the list box of the Color mode.

5. Select from the below checkboxes:

  • Dithered: It simulates the color's number than those present. This option will be present for various images that use 256 or fewer colors.
  • Always overprint black: It overprints black if black is any top color.
  • Anti-aliasing: It smooths the bitmap's edges.
  • Transparent background: It makes the bitmap transparent background.

Cropping bitmaps

Bitmap cropping removes the bitmap's unwanted area. To crop any bitmap into the rectangular shape, we can apply the Crop tool.

To Crop the bitmap

1. Select the Shape tool from the Toolbox.

2. Choose the bitmap.

3. After that drag any corner node for reshaping the bitmap.

4. Press Bitmaps > Crop bitmaps.

Note: We can't crop the bitmap consists of multiple objects.

Changing the bitmap's resolution and dimensions

After we insert the bitmap into any drawing, we can modify its resolution and dimensions.

To modify the bitmap's dimensions

1. Choose the bitmap.

2. Press Bitmaps > Resample.

3. Select the measurement unit from the Width and Height

4. Fill the values inside the below boxes:

  • Width
  • Height

To modify the bitmap's resolution

1. Choose the bitmap.

2. Press Bitmaps > Resample.

3. Fill the values inside the below boxes within the Resolution area:

  • Horizontal
  • Vertical

Straightening bitmaps

A dialog box, i.e., Straighten image allows us to quickly correct the bitmap straighten images and lens distortions. This aspect is very helpful to straighten images that were scanned or taken over an angle and include lens distortions.

To straighten images

1. Choose any image.

2. Press Bitmaps > Straighten image.

CorelDRAW Implementing with bitmaps

3. Move the slider, i.e., Rotate image, or fill the value among -15 and 15 inside the Rotate image

4. Move the slider, i.e., Grid to maintain the grid cell's size if necessary.

5. To straighten and crop an image, select the dialog box, i.e., Crop image.

Removing scratch and dust marks from a bitmap

We can improve the representation of the bitmap quickly by removing scratch and dust marks. The scratch and dust filter works if we eliminate the contrast among pixels that overtakes any contrast threshold we set.

To remove scratch and dust marks from a bitmap

1. Press Effects > Correction > Dust and scratch.

CorelDRAW Implementing with bitmaps

2. After that move from the below sliders:

  • Threshold: It sets the noise reduction's amount.
  • Radius: It sets the pixel's range applied to generate an effect.

Using special effects

We can use several kinds of special effects on the bitmaps, like artistic effects and 3D (three-dimensional).

To use any special effect

1. Choose any bitmap.

2. Select Bitmap, select any special effect we wish and then press an effect.

CorelDRAW Implementing with bitmaps

3. Maintain the settings of special effects.

To insert any plug-in filter

1. Press Tools > Options.

2. Double-click on the Workspace, and press Plug-ins from the list of categories.

3. Press Add.

4. Select any folder including the plug-in.

Bitmap colors

CorelDRAW allows us to modify colors in various monochrome images. It also allows us to use Postscript halftone screens for optimizing black-and-white and color bitmaps to print, mask colors, and show and hide colors. The monochrome bitmaps contain two colors, white and black. We can replace white and black with color over the color palette.

Also, color masking enables us to modify chosen colors without changing other colors within an image. We can save the color mask of a bitmap to any file and then open this file for further usage.

To apply the screen over the bitmap

1. Choose the bitmap with the help of the Pick

2. Select the Interactive fill button from the toolbox.

3. Click on the Uniform fill button over the property bar, and press the Edit fill

4. Press on the Palettes

5. From the list box of Palette, select the fixed palette.

6. Press Options, and press Postscript options.

7. Select any option inside the list of Type for setting the line type or dot shape.

8. Type the value inside the Frequency box for settings the lines or dots number that illustrate in every screen inch.

9. Type the value inside the Angle box for setting the lines or dots that illustrate over the screen.

To display or hide any color in the bitmap

1. Choose the bitmap with the help of the Pick

2. Press Bitmap > Bitmap color mask.

3. Select from the below options:

  • Show colors
  • Hide colors

3. Select any folder where the file of the color mask is stored.

4. After that double-click on the file.

Image adjustment lab usage

An image adjustment lab allows us to correct the tone and color of most images easily and quickly. It consists of manual and automatic controls, which can be managed in the logical order for image correction. It is efficient to retouch or crop an image's area before starting the tone and color correction.

To correct tone and color in an image adjustment lab

1. Press Bitmaps > Image Adjustment Lab.

CorelDRAW Implementing with bitmaps

2. Press Auto adjust.

3. Implement from the below tasks:

  • Adjust a slider, i.e., Temperature to cool or warm many colors, and fine-tune a color correction through adjusting the Tint slider for correcting colors inside an image.
  • Move the slider, i.e., Brightness in the right direction for lightening an image and in the left direction for brightening an image.
  • Move the slider, i.e., Contrast in the right direction for making light areas lighter and in the left direction for making dark areas darker.

Adjusting the tone and color

CorelDRAW allows us to adjust the tone and color of a bitmap. We could replace the colors and also adjust the intensity, lightness, and brightness of the colors. We can also adjust the tone and color of a bitmap automatically with the help of a command, i.e., Auto Adjust.

To adjust the tone and color automatically

1. Choose the bitmap.

2. Press Bitmaps > Auto adjust.

To adjust the tone and color with the adjustment filter

1. Choose the bitmap.

2. Press Effects > Adjust, and press the adjustment filter.

3. Describe the settings we wish.

Transforming tone and color

We could transform the tone and color of any image to generate any special effect. We can create an image that appears like any photographic negative and flatten an image's appearance. For transforming the tone and color of a picture, we can apply the below effects:

  • Invert: It enables us to reverse an image's colors.
  • Posterize: It enables us to reduce an image's tonal values.
  • Deinterlace: It enables us to remove the lines from the interlaced or scanned images.

To transform tone and color

1. Choose the bitmap.

2. Press Effects > Transform, and select from the below options:

  • Invert
  • Posterize
  • Deinterlace
