The document discusses working with images, including definitions of 2D and 3D images, raster and vector graphics, resolution, scanning images, and basic image manipulation tools in Microsoft Paint like resizing, cropping, flipping, rotating, inverting colors, and using brushes.
Working with images
- 1. What Image, picture, photo, or memory that you have and you can’t ever let go of it and don’t want to lose it? Anong imahe, larawan, o ala ala na meron ka na ayaw na ayaw mong mawala sa yo?
- 3. WHAT IS AN IMAGE? • An image is a visual representation of something. It can be 2D or 3D. 2D means two- dimensional object, like a drawing or painting with only two dimensions such as length and width, but no thickness or height. 3D means three- dimensional object, like a model or a sculpture with three dimensions such as length, width, and height.
- 4. How about Graphics? • Graphics may refer to the process of something by which a computer displays images. However, we should call all digital images “graphics”, and refer to the computer programs as graphic software.
- 5. Different Image File Formats – Vector graphics – these are composed of mathematical formulas that represent images. They are not dependent on their original resolution and are flexible enough to be scaled in many different ways without affecting the final resolution. – Raster graphics – also known as “bitmapped graphics”, these are image information rendered as pixels. They are highly dependent on their original resolution. – Meta format images – these are file formats that can be used by different applications. They can accommodate both vector and raster information.
- 7. Resolution • Resolution is the clarity of an image that is measured by dots per inch (dpi), it means that per one-inch line there are 300 dots or pixels. This translates to 90, 000 dots per square inch.
- 8. Scanning Images • Scanning images is important to be acquainted with obtaining graphics digitally. • A Scanner is a piece of hardware that converts light reflected from the object being scanned, and it creates a digital image of the object.
- 9. Image Manipulation Using Microsoft® Paint
- 10. Tools
- 11. Resizing • Step 1: Click Home tab, then click the resize button. • Step 2: Type higher or lower values for horizontal and vertical percentage, then click OK. You can press Ctrl + W.
- 12. Cropping • Step 1: Click the Select button, then draw around the area of the image you want to crop. • Step 2: If you’re done dragging the area that you want to crop, you can now click the Crop button. You can press Ctrl + Shift + X.
- 13. Flip/ Rotate • Step 1: Click Rotate button, to rotate the image choose your desired degree angle from the options. You can choose Left 90°, Right 90°, or 180° angles. • Step 2: For you to flip the image, click Rotate button then choose your desired rotation. You can choose Flip vertical or Flip horizontal.
- 15. Invert Colors • This creates an image with inverted colors like a film negative of a color photograph. • Step 1: Draw or drag around the area of the image you want to invert. • Step 2: Simply press Ctrl + Shift + I.
- 16. Brushes • This allows you to create more complex images.
Editor's Notes
- #2: Maraming Salamat sa inyong mga kasagutan. Patuloy nyo lang itago yang mga ala ala na iyan kasi iyan ay pwede nyong gawing inspirasyon sa inyong pamumuhay. AMEN! Kaya ko po natanong ang mga larawan, imahe at alala dahil ang pag uusapan po natin ay (click)
- #3: Lahat ng mga bagay tungkol sa image, paano ba nabubuo ang isang image, saan galling ang isang image, ano ang parts ng image, ibat ibang uri ng image pinag kaiba ni image kay graphics ay pag uusapan natin. But first before that lets define what is AN image.
- #4: Image is a visual representation of something. Pag sinabing representation, ito po yung nag papakilala, nag papakilatis, nag papaliwanag, In a way na nakikita natin yung isang bagay sa kung ano ba ang istura nya, we are not gonna make use of our imagination, hindi na natin need mag imagine kasi ito na sya, hawak na natin it can be picture or something else na pwedeng hawakan, nakikita na natin sya as is. That is an image, There are two basic tyes of image the 2D or two dimensional and 3D or the 3 dimensional Seeer diba po may 4d pa at 5d. Mamaya pag uusapan natin, o kaya I google nyo kung excited kayo Two dimensional is something like a drawing, image, painting or a picture ng krash mong apaka pogi at kakagigels.. No, ayun si two dimensional. Kaya sya two dimensional kasi two dimensions lang ang meron like lenght and width lang ang meron sya haba at lapad lang ang meron siya. And those dimensions are leght and the width. Parang sa math, para makuha ang area ng rectangle, what is the formula? Width x lenght… Unlike 3 dimensional, there is a space, may roon na syang kapal, sa math ang square ay nagging cube na, yung width and lenght ay nadagdagan ni kumareng height. Sample ng 3 dimensional is sculpture at kung kanina picture lang ni krass, ditto sa 3 dimensional si krass na mismo be!pag Nakita mo in person si krass ng naka stop, di gumagalaw that is three dimesnional 4D gumagalwa na paligid si krasss gumagalaw naaaa. Pero ikaw di gumagalaw, tanging nasa paligid mo lang sa 5D kasama ka ng gumagalaw sa gumagalaw na paligid. Kasama mo na si krass holding hands while wlaking na kayo. You belong to the image na. you are there. 6D lang ganon! Wag oa.
- #5: Graphics in laymans terms is soft copy. Salitang kanto, soft copy, o salitang nakasanayan ito po ay soft copy. Sa image it can be touched it can be hugged or can be kissed. Nakooo alam ko naman na kinikiss nyo mga picture ng krass nyong koreano. Graphics soft copy palang sya, nasa loob pa sya ng pc, hindi pa napipirint, nasa cellphone pa sya wala pang pangbayad pang print.
- #6: Vector grapgics is a graphics made by anchor points, paths and mathematical formula. Kumabag sukat sukat na sukat sya. Naalala nyo nung bata kayo, yung coloring book nyo na mayroon numbers tapos pag dudugtungin yung mga numbers pata makabuo ng isang image ? That is a type of vector graphics, which the numbers are the anchor pointsand and the trace are the paths. Kung papalikihin sya like 4 by 3 2 by 2 or so on that is the mathematical formula. Sa raster graphics naman it is made of milyons of colored picture points or pixels. And the graphics under raster has only limited amount of pixels. Kaya pag zinoozoom in pixelated sya or maraming box eme dun sa picture,. Tanong, ano ang mas malinaw? RASTER or VECTOR?
- #7: Vector, kasi ang vector ay sukat na sukat, mathematically recalculated. Unlike sa raster, kung ano ang nakacapture mo ayun na sya. Di na mababagao. Sa vector kasi you will create the graphics, sa raster, you will capture the graphics.
- #8: Resolution is kung gaano kalinaw ang isang image, resolution is measured by pixels.
- #9: Scanning is the way to make an image as a graphic. Diba sabi natin kanina, si image is the hard copy, I scan si image pag na scan na the product will be the graphics, now it is the soft copy of the image earlier. Scanner ang ginagamit para ma scan ang isang image at maging graphics
- #10: Here in image manipulation, we will learn how to rotate, resize, crop, and invert colors using the Microsoft paint. Mejo alam nyo nato. Kaya ang may alam, babagsak. Kunwari wala pa kayo alam haaaa.
- #11: Rectangular selction and free from selction tool is a cropping option. Pwedeng i tetrace nyo yung I ka crop using free selction or just a box using the reactangular selection Eraser tool use to draw line and create color. Charot of course use to erase mistakes eraser ng eeeh. Pencil tool use to draw just like a real pencile kaya lang sa paint, graphically. Fill, use to fill shapes and areas with colors. Brushes, use to draw with colors. Shapes. Alam nyo na yan. Day care palang kayo Colors din alam na yan. Text tool, use to write text, use to put words in the artwork inside Microsoft paint Magnifier, use to magnify objects in your work Color picker or the medicine dropper. Use to pick colors in the art that cant be found on color pallete
- #18: And that is working with imagesss. Sana po me natuutnat kayo kahit papano Next lesson, we will be talking about the proper etiquttes in using the internet connections.
