Creating mask images using MagicMedia
and Microsoft Paint (MSPaint).
|
1. The tiger mask
|
From the tigertr0 image, we want to have only the tiger and we want to
have it mirrored. Load the tigertr0.jpg into the Image Viewer, start
the effects dialog, apply 'Rotate/Flip/Horizontally' to mirror the
image.
Start the Crop frame
('Crop image' button in the second controlbar at the top of the viewer).
Adjust the frame, right popup click the frame and apply the
'Crop'-Menuitem (see images tigertr1.jpg and tigertr2.jpg).
With the
resulting image, start the effects dialog, go to the 'Transparency' page.
A couple of clicks on the Target preview image, holding down the
[SHIFT] key, maybe changing the 'Range' and 'Low Pass' trackbars a little,
results pretty fast in a coarse mask of the tiger
(images tigertr3.jpg, tigertr4.jpg and tigertr5.jpg).

To clean up the details, load the tigertr5.jpg into MSPaint (Hint:
right click the file on the FilePanel, select 'System Menu/Open with'
and select 'Microsoft Paint' from the list. If it is not in the list,
select 'Choose Program...' and search for the MSPaint program). In MSPaint,
choose the rectangle
tool with the 'Fill'-style (see tigertr6.jpg and MSPaint's help for setting
the style). After drawing a couple of filled rectangles, the rest needs
to be cleaned up with the brush tool. Select the largest round brush
shape (tigertr7.jpg) and carefully remove the debris without destroying
the tiger's shape (..in case, MSPaint has an 'Edit/Undo' option).

|
Finally we have the tiger mask: tigertr8.jpg. Ooohhps - one of the tiger's
ears became too transparent. No problem: load the tigertr8.jpg into the
Image Viewer, load the tigertr2.jpg into a second Image Viewer (hold down
the [CTRL]-key, doubleclick the thumbnail to open a second Image Viewer).
Crop the ear as described above and
depicted in images tigertr9.jpg and
tigertra.jpg.
Copy the resulting image to the clipboard (right popup click the image,
select 'Copy'-menuitem). In the first Image Viewer (tigertr8-image), right
popup click the image and select the 'Paste as overlay'-menuitem.
MagicMedia remembers
the position of the frame before the Crop-operation and automatically
places the overlay frame at the right position. Right popup click the frame,
'Stamp/Aliased'.

After correcting with the same technique a few more of those
transparency-overflows, we finally end up with the tiger mask
- hihi - ready for some games :)
|
|
To give the image a little bit more color dynamic, we apply the
'Auto Colors' filter with limits set to 2 (Effects/Histogram/Auto Colors).
As there are similar colors in the background, we need to surround the
endeavered regions of the mask image with a cutoff color. After doing this
with MSPaint (ridert2.gif), load the image to the Transparency Editor,
select the Cutoff color (yellow in this case) as Transparent color and
proceed masking the image
as described above
(ridert3.jpg through ridert5.jpg).

In ridert6.bmp, some of the grass leaves have been removed using
MSPaint's brush and color picker.
|
|
To create the rabbit2.gif with the rabbit being the transparent part:
load the rabbitt6.gif into the Effects/Tranparency editor, uncheck
'Contiguous', click on
the rabbit in the Target preview and notice how the colors change.
Set the range to ~100 and click, with the [Shift]-key pressed, on the
parts of the rabbit not having already the transparent color.
