Use Landscape for Wide Figures

Landscape is the standard format for the private sector.

In general you will have less trouble projecting a landscape slide than a Portrait Slide, and Landscape is preferred in the corporate world.

This also helps you to avoid adding too many lines to a slide. The latter can result in data overload for the audience & may result in each line of text etc. being too small.

Picture Sizes

This can be a point of confusion & frustration!!!

Screen resolution is approximately 70 pixels/inch.

Consequently, you can scan an image at 100 ppi (dpi) & it will look great as long as it is displayed at its actual, original size.

Thus, a postage stamp scanned at 100 ppi(dpi) would look great on the screen at its actual size.

If you tried to enlarge it by the method below, it would quickly become pixilated & you would see large square pixels and a blurry image.

If you scanned the postage stamp at 300 dpi, you could enlarge it by a factor of 3-4X and it would still look OK at 100 dpi.

Consequently, when you scan images you need to keep in mind how much you might like to enlarge the scanned image for display.

Most scanners will allow you to select the dpi and the final output size. Thus, you could scan at 100 dpi for a 3 x 4 inch image.

I believe that dpi (dots/inch) is the equal of ppi (pixels/inch). ppi refers to Printing an Image, dpi is related to how the Image is seen on a Computer Monitor.

Are you confused!! If so skip the next section!!!

When I scan photographic slides with the HP Scanner in 402, I may get a file that is 900 x 1200 pixels in area.

I can reduce the size of the file's appearance on the screen by the technique below. However, the amount of memory used by the file is unchanged. The image size is appears less but the file size is not changed.

Most Image Processing Programs like PhotoDeluxe, PhotoShop etc. have commands which resize the image and the file size at once.

Consequently, I might use the 900 X 1200 as an archival file and create a 600 X 800,  a 300 X 400 and a 100 x 133 pixel file. The latter would be a good Thumbnail Image.

The others can be used variously according to the size I need. However, none of these images will tolerate stretching. You can squeeze them to make them look smaller.

Stretching or Squeezing an Image

If you click on the image in your PowerPoint slide you will notice some small square handles that appear at each corner of the image, and at the midpoints between the corners around the perimeter of the Image.

How about that for a run on sentence!!

Use the mouse to move the cursor to one of the corner handles.

Depress the left mouse button and hold it down with your finger.

Drag the mouse centrifugally to stretch the image and centripetally to squeeze it.

Note that the aspect ratio of the sides is retained.

(Boy do I get annoyed when people try to "show off" by using fancy terms like aspect ratio!!!!)

Do the same for the handles located between the corners.

Dragging these will increase the height or width independently, thus altering the aspect ratio.

 

 

Application of Letters & Labels

Click on the Text Box Tool in the Toolbar.

Drag the mouse to set the approximate size of the box.

Type in the Letter or Word.

It will appear in the default format.

Select the text within the box and format it as you wish.

These text format commands are the same basic text commands used by most Windows programs.

Click outside the Text Box to see how it will look. Note the sizing handles on the perimeter of the Text box.

Drag the Text Box to the desired spot by placing the cursor BETWEEN the sizing handles, depressing the left mouse button  and moving the mouse.

Click outside the box to secure it in place. If you want to move it later, simply click on it.

The sizing handles will appear and you can drag the box to a new location.

If you use a font size that is greater than the area of the box, or if your word is too long, Click on the Text Box and use the sizing handles to expand the area of the box so that you can see all within.

You can format the Text Box by selecting Format -> Text Box from the Format Drop Down Menu.

For scientific papers use black or white as the basic font colors.

You may need an opaque white or black background depending on the native background inside the image.

If you want to get fancy, you can choose a semi-transparent background for the Text Box. This will allow some of the features of the underlying image to show through.

You may also need a black or white outline of the box perimeter. This can also be accomplished via the Format -> Text Box  Drop Down Menu.

Example Text for the figure above

Sundew plants belong to the genus Drosera. The are generally found in acid bogs in which Sphagnum moss is prevalent. They have large multicellular trichomes called colleters (Fig. 1). These are elevated from the adaxial surface and have red tips that attract insects. The tips are secretory heads and produce a sticky substance which captures prey. The leaves slowly change shape to partially envelop the insect which decomposes. Sessile glands absorb nutrients released by the prey.
