Description

JINZO PAINT (4-level gray version) is a paint-based drawing tool that runs on WindowsCE.
In addition to basic drawing, cut-and-paste, loupe, fill, straight line/rectangle/ellipse drawing, and save/load functions, it is equipped with powerful color calculation functions.
The data that can be handled is only the 4-gradation data of the actual screen size.


Cassiopeia E-55 and Jornada720 are used for development and operation confirmation in the author's environment.

It can handle 2, 4, 8, 16, 24 bit/pixel uncompressed BMP, but it will be converted to 4 shades of gray.
You can load an image of any size, but if it is smaller than the actual screen size, it will be aligned to the upper left and the margin will be white. It is also truncated if it is larger.

LINE
straight line
Rectangle
rectangle
Rectangle Fill
A filled rectangle
Circle

A filled ellipse
For PsPC, straight lines become horizontal and vertical lines, rectangles become squares, and ellipses become circles while the action button is pressed.

(4) Pen size, (5) Pen color, (6) Pen pattern, (7) Eraser size

You can change the pen size by pressing (4).

You can change the color of the pen by pressing (5).

You can change the pen pattern by pressing (6).

There are 9 types of pen styles: 100%, 87.5%, 75%, 62.5%, 50%, 37.5%, 25%, 12.5%, and custom tone.
If the density is less than 100%, it is thinned out in places, but the thinned dots will be the background color (the color specified in the BackGround Color dialog). (Background color in the above figure (upper) = None)
The figure above (bottom) is drawn at 50% over 75% and 25%, but even if you draw a style with a low density on top of a style with a high density, the density will remain at the original high density.
Select Reverse to reverse the pattern.
The custom tone uses the upper left 16x16 pixel pattern of the image data specified by the Load CustomTone command as a binary style. This image data can be drawn and saved with JINZO Paint.

You can change the size of the eraser by pressing (7).
"Eraser color = white, pattern = 100%."
Since the pen size, color, and style settings just before selecting the eraser remain, you can resume drawing from those settings by pressing the pen button again or selecting the pen from the tool button.
(8) Loupe

By magnifying glass mode, it is possible to edit with an enlarged image.
The magnification can be set from 1x (normal), 2x, 3x, 4x, and 8x.
If it is other than 1x, checking x1view will display the original size image in the upper left.
The original size display specification is saved individually for each magnification, and at startup, 2x is hidden, and 3, 4, and 8x are displayed.
You can scroll with the Hand tool or the cursor keys. Also, at 1x, the scroll coordinates return to the origin.

(9) Undo

You can undo once for each type of drawing.
Background color setting

"Set the background color when drawing with a pen."

When you select BackGround Color from the Edit menu, the dialog shown above will open.
There are radio buttons for transparent color and black, dark, light, and white. If the pattern is 100% or less, the color specified here will be the background color.

The upper figure (top) is a drawing example with a background color = no color, and the upper figure (bottom) is a drawing example with a background color = light.
Color conversion function

Set the color conversion for the ClipBoard data being displayed.

When you select Color Convert from Edit, the dialog shown above will open.
From the top, there are four drawing colors: black, dark, light, and white, each with radio buttons for four conversion colors. In the above figure, black ? black, dark ? white, light ? dark, white ? white are set.

"Here, look at the example."
This is an example of drawing a sketch.

Draw a rough sketch with a thin layer.
Draw the main line in black.
Select RectArea?Copy to copy the target to his ClipBoard.
By checking light ? white, the light part will be converted to white, so you can erase the stroke line by pasting this.

Color calculation function

Set the relationship between the drawing color and the color of the original image.
Selecting the Color option from the Edit menu opens the dialog shown above.
From the top, there are four drawing colors: black, dark, light, and white, each with a check box for the four original image colors. In the above figure, the drawing color = dark and the background color = black are not checked, and the original image color = light and white are checked.

"Here, look at the example."

In the case of drawing in dark over black and light, normally it is drawn in dark over black and light as above. However, if you uncheck the drawing color = dark and the original image color = light in the color options, it will not draw lightly as shown below.
In this way, you can freely set whether to draw with the drawing color against the color of the original image.

In addition, I will introduce some convenient ways to use the color calculation function.

(i) This is an example of coloring a black outline.

If you want to paint the contour line in the above image (upper), you can paint the contour line as it is by unchecking the drawing color = dark/light color and the original image color = black in the color options. .

(ii) This is an example of adding a dark shadow on top of a light shadow.

If you don't set the color option, it will be painted dark over black and white like the bottom left, so it's troublesome to correct.
In the color option, if you uncheck the drawing color = dark and the original image color = black / white and check only light, it will not draw for black / white and only draw lightly. , you can draw a dark color without worrying about it sticking out.

5. About data conversion with PC

"Notes on exchanging data with a computer."
The 4-gradation data handled by WindowsCE is a type of BMP called 2bp format. 2bp stores four 24-bit palette data.
When converting (and transferring) bmp ? 2bp with the CE service, the following palette data must be embedded. This program uses this data.
black { 0x00, 0x00, 0x00 }
dark { 0x80, 0x80, 0x80 }
Thin { 0xC0, 0xC0, 0xC0 }
White { 0xFF, 0xFF, 0xFF }

However, some applications embed the following palette data in 2bp or bmp.
black { 0x00, 0x00, 0x00 }
dark { 0x55, 0x55, 0x55 }
Thin { 0xAA, 0xAA, 0xAA }
White { 0xFF, 0xFF, 0xFF }

If these data are converted and transferred using the CE service, the conversion may not be performed correctly, resulting in garbled colors. I think it's fair to say that this is a lack of CE service.
There is no problem if data is only exchanged between this program and the CE service, but if it is exchanged with an application that embeds different palette data as described above, the image data cannot be handled normally.
"We have not yet established a solution for this." The current situation is to deal with it by rewriting it with a binary editor. If you have a smart solution, please let me know.
6.Tips

If you set the sound to play when you tap the screen, the pen drawing may become dirty. In that case, turn off the sound in the system settings.
Depending on the model, if the pen pressure is weak, drawing may behave unexpectedly. In that case, please write with stronger pen pressure.
If you start this program with the setting to automatically hide the taskbar, you can make the drawing area as wide as the taskbar.

Installation Instructions

For installation, copy JZPaint.exe to any folder in WindowsCE.
For uninstallation, delete JZPaint.exe from WindowsCE.
This program does not operate the registry.
