Markup is an underutilized feature in OS X Yosemite, and many people don’t even know it exists. You can use markup in OS X’s email program to edit and annotate your attached pictures or PDF mails. This tool is very easy to use, as long as you learn, it can save a lot of time and make you more productive. The following editor will teach you how to use it.
1. Activate markup
The markup feature should be turned on by default, but you’d better make sure before you start using it.
The first step is to open the apple menu and select system preferences.
Second, select the extension panel, click “actions”, and you’ll see a check box called “markup.” make sure that the option is checked before continuing.
2. Markup hidden in email
As mentioned above, this tool is used in the email program, but you won’t find any menu options about it in the email. To use this tool, you need to write a new email or reply to an email, and the email must contain a picture file or PDF file.
The steps to activate markup are as follows: put the cursor on the attachment, and a small icon will be displayed in the upper right corner. Click the icon to open a menu and select the “mark up” option. Then a new window will be opened for the e-mail. The mail information and attachments will be displayed in the new window, and the markup toolbar will appear on the top.
3. Markup tool
Once the toolbar is activated, you can see the following options above:
Sketch: the sketch tool allows you to doodle on images or PDF. If you draw a figure close to a standard pattern, such as a circle or a triangle, the system will automatically correct it to a standard pattern.
Pattern: This tool allows you to select one of the existing graphics and place it anywhere in the file.
Text: text box can be added anywhere in the document, and users can make remarks in the text box.
Signature: allows you to add a signature automatically.
· pattern style: this menu allows you to edit the style of the pattern, including the width of the line, the range of the shadow, and the direction of the arrow.
· border color: allows you to quickly and easily adjust the border color of the pattern.
Color fill: you can customize the color inside the graphic.
· text style: this option allows you to adjust font style, size, color, and alignment.
Although each of the markup tools is very simple to use, sometimes it can be cumbersome, which requires practice, but once you have the knack, it can be very useful.
4. Get pictures
Download Apple Os X Yosemite
Markup also has a very useful tool: you can move the mouse to the edge of an image, and then a grab icon will appear. You can use it to quickly get pictures instead of downloading them to your computer and viewing them with another software. This tool is quite handy.
