Abstract

The present disclosure provides a picture display method and apparatus that relate to the field of image processing and are increase flexibility of picture display and reducing a memory occupation rate of a terminal on the premise of not modifying an attribute of an original picture. The method and apparatus include receiving an instruction for displaying a picture; obtaining, according to an identifier of a to-be-displayed picture included in the instruction, an original bitmap of the to-be-displayed picture and searching, a database of a current device for a pre-stored first rotation angle corresponding to the to-be-displayed picture; adjusting, according to a resolution of a current screen and/or a current window size, a display size of the original bitmap of the to-be-displayed picture, so as to obtain a compressed bitmap of the original bitmap; and displaying, according to the first rotation angle, a compressed bitmap of the original bitmap.

Claims27

Dependent claims

A method for displaying a target picture, the method comprising:

loading, by an electronic device, an original bitmap of a target picture;
searching, by the electronic device, a database stored in the electronic device for a first rotation angle corresponding to the target picture, wherein the database is separate from the target picture;
and
displaying, by the electronic device, the original bitmap according to the first rotation angle.

1 more element

An electronic apparatus for displaying a target picture, comprising:

a memory storing a set of instructions;
and
a processor in communication with the memory,
wherein, when the processor executes the set of instructions, the processor is configured to cause the electronic apparatus to:
load an original bitmap of a target picture;
search a database stored in the electronic apparatus for a first rotation angle corresponding to the target picture, wherein the database is separate from the target picture;
and
display the original bitmap according to the first rotation angle.

5 more elements

A non-transitory processor-readable storage medium having a set of instructions stored thereon, wherein the set of instructions, when executed by a processor of an electronic device, instructs the processor to cause the electronic device to perform actions comprising:

loading an original bitmap of a target picture;
searching a database stored in the electronic device for a first rotation angle corresponding to the target picture, wherein the database is separate from the target picture;
and
displaying the original bitmap according to the first rotation angle.
