Description
Technical field
The present invention relates to drawing for software programming technical field of image processing more particularly to a kind of big pixel B MP format-pattern
Method processed.
Background technique
Pixel coordinate is converted into generally by acquisition two-dimensional vector coordinate to the processing method of image in program then to adjust
Such as with drawing tools library: EasyX, GDI, GUI draw picture, but these tool storage rooms such as EasyX, GDI, GUI can be drawn
The pixel size of picture has certain limitation, and when the pixel size of picture limits range beyond it, program can not establish the picture
The painting canvas of plain size or the painting canvas of the pixel size can establish success, but image can only draw out part, cannot draw
Complete picture out, therefore the picture of big pixel has been depicted as certain technical bottleneck.
For example, the BMP format picture that 60253*17181 pixel is drawn in the drawing tools library that C++ is provided can only draw striking out
Portion's picture.Referring in detail to the following figure, wherein Fig. 1 is that target draws picture, and Fig. 8 is the imperfect picture of practical drafting.
Summary of the invention
It is necessary to propose a kind of method for drafting of big pixel B MP format-pattern.
A kind of method for drafting of big pixel B MP format-pattern, comprising the following steps:
The first image and the second image will be divided into advance to drawing image；
The first painting canvas is established, the second painting canvas is established；
The occupied parts of images position of second image is plucked out on the first painting canvas, and is deposited to second painting canvas, and
The mark coordinate points of the parts of images position plucked out are recorded on the first painting canvas；
The first image and the second image are drawn on the first painting canvas and the second painting canvas respectively；
The second painting canvas for having the second image will be drawn to be filled in inside the first painting canvas, keep the origin coordinates point and the of the second painting canvas
Mark coordinate points on one painting canvas are overlapped, and are formed in the big image drawn on same painting canvas；
The output of first painting canvas is stored in final BMP file, the output for scratching the big pixel image of totem culture is completed.
Preferably, the maximal side of the first image and the second image is not more than 60253/2.
Preferably, recorded on first painting canvas coordinate of the mark coordinate points of parts of images position plucked out for (Xa,
Ya, W, H), wherein Xa, Ya are respectively the coordinate and Y axis coordinate of the X-axis of painting canvas, and W is the length of the part painting canvas plucked out, and H is
The height of the part painting canvas plucked out, with to the parts of images plucked out position and profile uniquely positioned.
Preferably, the first image, the second image, third image will be divided into advance along X-direction to drawing image；
The first painting canvas is established, the second painting canvas is established, establishes third painting canvas；
The occupied second part picture position of second image is plucked out on the first painting canvas, and is deposited to second painting canvas
On, and the second identifier coordinate points of the second part picture position plucked out are recorded on the first painting canvas；It is scratched on the first painting canvas
The occupied Part III picture position of the third image out, and deposit to the third painting canvas, and remember on the first painting canvas
Record the third mark coordinate points of the Part III picture position plucked out；
The first image, the second image, third image are drawn on the first painting canvas, the second painting canvas, third painting canvas respectively；
The second painting canvas for having the second image will be drawn to be filled in inside the first painting canvas, keep the origin coordinates point and the of the second painting canvas
Second identifier coordinate points on one painting canvas are overlapped；The third painting canvas for having third image will be drawn to be filled in inside the first painting canvas, protected
It holds the origin coordinates point of third painting canvas to be overlapped with the third mark coordinate points on the first painting canvas, is formed on same painting canvas and draws
The big image arrived；
The output of first painting canvas is stored in final BMP file, the output for scratching the big pixel image of totem culture is completed.
Preferably, the first image, the second image, third figure will be divided into advance along X-axis and Y direction to drawing image
Picture；
The first painting canvas is established, the second painting canvas is established, establishes third painting canvas；
The occupied second part picture position of second image is plucked out on the first painting canvas, and is deposited to second painting canvas
On, and the second identifier coordinate points of the second part picture position plucked out are recorded on the first painting canvas；It is scratched on the first painting canvas
The occupied Part III picture position of the third image out, and deposit to the third painting canvas, and remember on the first painting canvas
Record the third mark coordinate points of the Part III picture position plucked out；
The first image, the second image, third image are drawn on the first painting canvas, the second painting canvas, third painting canvas respectively；
The second painting canvas for having the second image will be drawn to be filled in inside the first painting canvas, keep the origin coordinates point and the of the second painting canvas
Second identifier coordinate points on one painting canvas are overlapped；The third painting canvas for having third image will be drawn to be filled in inside the first painting canvas, protected
It holds the origin coordinates point of third painting canvas to be overlapped with the third mark coordinate points on the first painting canvas, is formed on same painting canvas and draws
The big image arrived；
The output of first painting canvas is stored in final BMP file, the output for scratching the big pixel image of totem culture is completed.
The present invention solves to draw using common drawing practice using the method for scratching figure supplement on same size painting canvas
The problem of making larger pixel picture, this method is understanding and code is realized upper relatively simple, conveniently, there is certain use value.
