Specification for the Image Resources Used by mGNCS Skin Renderer

Foreword

  • Types of all the elements of skin are file name, and the file name corresponds to the image loaded to the system buffer pool (through LoadResource). The two must be consistent

  • renderer actually does not store file name, but only stores RES_KEY generated by these file names, and then gets image through GetResource

  • Many controls have the distinction of status of normal, press, highlight, disable etc., for a control, each status is stored into an image, which is a huge waste for the process of storing resources and loading images, therefore, skin renderer in mGNCS continues to use the image use mode in MiniGUI, which is mixing the associated images into one, and taking different parts to use when drawing. For example, for button image, we design into combination image of five parts, and when we want to draw button of certain status, we take child image of this part to use.

alt

There are two drawing modes for the images:

  • Direct stretch fill drawing: This mode is not difficult to understand, which is enlarging the resource image according to the size of the drawing region with certain proportion to fill.

  • Segment fill drawing: This mode will divide the image (or child image) obtained into three segments according to the mode of up middle, down or left, middle right, and then fill the two ends separately. For the middle part, use the middle part in circulation to fill. We still take button as the example, as shown in the figure

alt

This mode can well reserve the border effect of "round corner" etc. When using images filled in this mode to design, please not that:

  1. For the boundary line of left, middle, right and up, middle, down segments, the images are different, which will be explained below_.

  2. Because the middle part will be used in circulation, note that transition shall be smooth_

NCS_IMAGE_ARROWS

File name

Arrow image

NCS_IMAGE_ARROWSHELL

File name

Arrow button image

Specification of the image:

  • arrow image is used for the drawing of arrows in the skin renderer, which is composed of 16 parts of small images from up to down, and each small image is a square. The internal corresponding relation is

  • 0-3 : statuses of the upward arrows (0-common, 1-highlighted, 2-press down, 3-forbid)

  • 4-7 : Statuses of the downward arrows (4-common, 5-highlighted, 2-press down, 3-forbid)）

  • 8-11 : statuses of the arrows leftward (8-common, 9-highlighted, 10-press down, 11-forbid)

  • 12-15 : statuses of the rightward arrows (12-common, 13-highlighted, 10-press down, 11-forbid)

  • In spin and scroll series of arrow_shell, effect used for realizing arrow button is composed of four parts of small images from up to down. Each small image is a square, and each part correspond to one status of the button:

  • 0-common

  • 1-highlighted

  • 2-press down

  • 3-forbid

  • In addition, arrow image is generally used in cooperation with arrow-shell image. When in use, it has the superimposition effect, so region around arrow is generally made transparent.

  • Direct stretch filling is adopted when using the image, and pay attention to reasonable design of the image.

mButton

Type

Explanation

NCS_IMAGE_PUSHBUTTON

File name

Image of push button

Specification of image

  • For the drawing effect used for pushbutton in skin renderer, the image is composed of five parts from up to down, and each part is a rectangular button, corresponding to five statuses of pushbutton:

  • 0 - common

  • 1 - highlighted

  • 2 - press down

  • 3 - forbid

  • 4 - “half selected” status in the three-status button

  • When drawing, if image is used to carry out segmental filling, the left and right ends are 6 pixels wide, and width of the middle segment is not limited. Pay attention to reasonable design of the image.

mCheckbutton

Property name

Type

Explanation

NCS_IMAGE_CHECKBUTTON

File name

Image of check button

Specification of image:

  • For the drawing rendering used for check button of skin renderer, the image is composed of eight parts from up to down. Each part is a rectangle, corresponding to eight statuses of check button:

  • 0~3: common, highlighted, press down and forbid status when not selected

  • 4~7: common, highlighted, press down and forbid status when selected

  • If the image is bigger than the drawing region, the image will be reduced to draw, otherwise image size is directly used to fill., Pay attention to image design

  • Example

NCS_IMAGE_TREE

File name

Image of fold/unfold switch in the tree

NCS_IMAGE_HEADER

File name

Image of the header part

Specification of the image:

  • For the rendering effect used for realizing the fold and unfold button in the tree control, the image is composed of equal up and down parts. The up part is the fold effect, and the down part is unfold effect

  • When in use, size of the image will be directly used to fill and it will not be stretched. So pay attention to the size of image design, and it shall not be too big or too small

NCS_IMAGE_TAB

File name

Image of PropSheet Tab page

Specification of image:

  • For the tab effect used for rendering propsheet page, it is composed of four parts from up to down. In mGNCS, only the first part and the third part are used, representing:

  • 0 - tab effect of inactive page

  • 2 - tab effect of active page

  • _Draw by segment, _ left, middle and right occupy 3, x and 4 pixel respectively, and pay attention to the design of image
