Raster Images Editing

This application includes several editing tools for raster images aimed at facilitating the digitizing work. We suggest you to perform the necessary modifications on the image before starting the design process.

Crop Image

Select the image you want to edit.

Click on the "Crop Image" button, on the tooltab LAYOUT.

The cursor will change to a cutting indicator.

Draw a rectangle over the area of the image that you want to preserve.

The part inside the rectangle will be preserved, the part outside will be deleted.

Color Reduction

Select the image you want to edit.

Click on the "Color Reduction" button, on the tooltab LAYOUT.

A window will open, where you can quickly reduce the number of colors of the image.

The window is divided in two panes:

The left pane shows the original image.

The right pane shows the final result.

It includes zoom and pan tools.

To confirm the color reduction, click on the "Return" button.

Raster_Editing_1

Move, Scale, Rotate on the workspace

Select the image you want to edit.

The selection box will appear. You can work with the corner and center grips to expand, compress, move and rotate the image freely.

Scale/Resize Proportionally

Drag any of the corner grips to adjust the size proportionally.

When you drag a corner grip, the scaling will leave the opposite corner fixed in its position.

Instead, if you press and hold the Shift key while dragging, the scaling will keep the center of the image in its position, and all the corners will scale following the movement of the mouse.

Raster Editing 3

Scale/Resize Not Proportionally

Drag any of the middle grips to adjust the size not proportionally.

When you drag the any of the middle grips, only one of the sides of the surrounding rectangle will move.

Instead, if you press and hold the Shift key while dragging, the dragged side and the opposite side will move in opposite directions.

If you place the mouse cursor to the central zone of the image, the mouse cursor will change its shape into a cross icon. Then, press and hold the left mouse button and drag it.

Raster Editing 4

Move

Place the mouse cursor inside the surrounding rectangle (the mouse cursor will change its shape into a cross icon).

Press and hold the mouse left button and drag it to move the position of the image on the workspace.

Raster Editing 4 C

Rotate

Press and hold the Ctrl key and then click and drag any corner grip.

 

vector_object_rot_1

Move, Scale, Rotate using the context tooltab

Move

You can accurately move the image position using the size and position tool on the Block Menu, by editing the values of the Position group.

Scale/Resize

You can accurately scale the image using the size and position tool on the Block Menu, by editing the values of the Size group.

If you want to keep the image proportion (aspect ratio), make sure to activate the padlock icon before changing the size.

Raster_Editing_7

Resize Tool

You can also re-size the image from the workspace, it you know the distance between 2 points of that image.

Click on the "Set Size" button.

Raster_Editing_6

Click on any point of the image and drag it.

The system will trace a line from the first point to the mouse position

Release the mouse button.

Raster Editing 10

The Image Scale tool is open. It shows the length of the traced line.

Specify the new length for the traced line.

Click the "OK" button to confirm.

The image will be scaled proportionally, according to the new lenght of the traced line.

Raster Editing 8

Set Angle tool

You can use this tool to rotate the image any angle. But probably this is the ideal tool when you need to adjust the zero angle on scanned images.

Raster_Editing_11

Click on the "Angle" button.

Draw a line.

Release the mouse button.

Raster Editing 12

The Set Angle tool is open. It shows the angle of the traced line.

Set the new angle value.

Click on Ok to confirm.

Raster Editing 13

The image will be rotated according to the entered value.
