T-Shirt Graphic 5: Rasterize & Edit White Pixels

1. Lesson Goals

SWBAT:

1..convert Vector Smart Object layers into PIXELS by RASTERIZING them

2...use the MAGIC WAND Tool to SELECT white pixels for deleting

3...use the Select > Similar option

4...use the paint bucket to REPLACE WHITE PIXELS with COLOR

2. Rasterize Vector Smart Object Layers

1. Hold the shift key and click to select all your Smart Object layers in your layers palette

2. Right click in the Layers Palette and choose "Rasterize Layers"

3. Notice that the Rasterized Layer will still be labeled as a Vector Smart Object but the little Vector icon will be gone. See above.

Rasterizing means to convert into pixels. Once you rasterize a vector smart object, you will not be able to scale it up without losing image quality.

3. Learn About Marching Ant Selections

1. Marching Ant selections can be made with any of the 9 PS Selections tools

2. Marching Ant selections are necessary to select specific pixels within a layer.

3. Marching Ant selections can only be made in one layer at a time.

4. Deselect a marching ant selection with the deselect option in the select menu

Select > Deselect

(Command D)

4. Use the Magic Wand to Select White Pixels

2. Use the Magic Wand Tool to select the fill area of one of your shapes in that selected layer You will see a flashing dotted selection area (called "marching ants")

5. Use Select > Similar

1. Select the layer you want to work in with the Move Tool

2. Click on some white pixels with the Magic Wand tool

3. Use the Select Menu > Select Similar option to easily select all the other white pixels in that layer.

Marching Ant Selections can only be made in one layer at a time.

6. Option 1: Delete All The White Pixels

1. DELETE!! Use the LARGE delete that's just above the RETURN key

2. To get rid of the marching ants, go to theSelect Menu > Deselect (Command D)

What does rasterizing do to vector images?

NB Do Now 11/12

Rasterizing converts Vector images into pixels.

NB Do Now Review

How are Raster images different than Vector images?

NB Do Now Review

RASTER (also called bitmap) images are made up of PIXELS and are RESOLUTION dependent. VECTOR images are made up of POINTS & LINE SEGMENTS and are RESOLUTION INDEPENDENT.

PS and Paint and Gimp are RASTER programs. AI, MS Word, etc or VECTOR programs.
