Adobe Photoshop
- We use Photoshop mainly to make image files which are linked from html documents and are displayed on homepages.
- Those image files must be of one of the following formats:
- Image files of Compuserve GIF format is named "????????.gif"
Image files of JPEG format is named "????????.jpg"
- Let us save those image files into folders named "doc".
- The prescription of a linkage to an image file, which is written in an html document, is as follows:
<img src="?????????/doc/?????.gif">
<img src="?????????/doc/?????.jpg">
- When you open a new file in Photoshop, the default format is "Photoshop 4.0".
This format allows us to use "layers".
It is often the case that you wish to save files in this format, for future modification or something.
Let us save those working files as follows:
- Suppose you are going to make a GIF file, to name it "triangle.gif", and to save it into a folder named "doc".
- Create in "doc" a folder, and name it "making".
- Save a working file into "making", with a suitable name, for example "triangle.ps". (Here "ps" is from "Photoshop".)
- Way of saving the current file as a GIF file :
- In the "Layer" window, select "Flatten Images"
- In the "Image" menu, select "Mode", and "Index Color".
- In the "File" menu, select "Save as ...."
- Save the file in "Compuserve GIF" format.
- Way of saving the current file as a JPEG file :
- In the "Layer" window, select "Flatten Images"
- In the "File" menu, select "Save as ...."
- Save the file in "JPEG" format.
