Nothing.

Requires

Glcd needs to be initialized, see Glcd_Init routine.

Example
// Draw image my_image on Glcd
Glcd_Image(my_image);
Notes

Use the mikroC PRO for PIC32 integrated Glcd Bitmap Editor, Tools > Glcd Bitmap Editor, to convert image to a constant array suitable for displaying on Glcd.

Glcd_Ext_Image

Prototype

void Glcd_Ext_Image(unsigned long image);

Description

Displays a bitmap from an external resource.

Parameters
  • image: image to be displayed. This parameter represents the address in the exteral resource from where the image data begins.
Returns

Nothing.

Requires

Glcd needs to be initialized, see Glcd_Init routine.

Example
Glcd_Ext_Image(153608);
Notes

Use the mikroC PRO for PIC32 integrated Glcd Bitmap Editor, Tools > Glcd Bitmap Editor, to convert image to a constant array suitable for displaying on Glcd.

Glcd_PartialImage

Prototype

void Glcd_PartialImage(unsigned int x_left, unsigned int y_top, unsigned int width, unsigned int height, unsigned int picture_width, unsigned int picture_height, code const unsigned short * image);

Description

Displays a partial area of the image on a desired location.

Parameters
  • x_left: x coordinate of the desired location (upper left coordinate).
  • y_top: y coordinate of the desired location (upper left coordinate).
  • width: desired image width.
  • height: desired image height.
  • picture_width: width of the original image.
  • picture_height: height of the original image.
  • image: image to be displayed. Bitmap array can be located in both code and RAM memory (due to the mikroC PRO for PIC pointer to const and pointer to RAM equivalency).
Returns

Nothing.

Requires

Glcd needs to be initialized, see Glcd_Init routine.

Example
// Draws a 10x15 part of the image starting from the upper left corner on the coordinate (10,12). Original image size is 16x32. 
Glcd_PartialImage(10, 12, 10, 15, 16, 32, image);
Notes

Use the mikroC PRO for PIC32 integrated Glcd Bitmap Editor, Tools > Glcd Bitmap Editor, to convert image to a constant array suitable for displaying on Glcd.

Glcd_Ext_PartialImage

Prototype

void Glcd_Ext_PartialImage(unsigned int x_left, unsigned int y_top, unsigned int width, unsigned int height, unsigned int picture_width, unsigned int picture_height, unsigned long image);

Description

Displays a partial area of the image, located on an external resource, on a desired location of the screen.

Parameters
  • x_left: x coordinate of the desired location (upper left coordinate).
  • y_top: y coordinate of the desired location (upper left coordinate).
  • width: desired image width.
  • height: desired image height.
  • picture_width: width of the original image.
  • picture_height: height of the original image.
  • image: image to be displayed. This parameter represents the address in the exteral resource from where the image data begins.
Returns

Nothing.

Requires

Glcd needs to be initialized, see Glcd_Init routine.

Example
Glcd_Ext_PartialImage(10, 12, 10, 15, 16, 32, 0);
Notes

Use the mikroC PRO for PIC32 integrated Glcd Bitmap Editor, Tools > Glcd Bitmap Editor, to convert image to a constant array suitable for displaying on Glcd.
