According to an image processing apparatus and a control method thereof of the present invention, a graphics drawing result is obtained in accordance with one or more graphics drawing commands included in drawing commands, a clipping command is generated from one or more moving image drawing commands included in the drawing commands, and clipped graphics is obtained by clipping the graphics drawing result using the clipping command. Further, moving image data processed in accordance with the one or more moving image drawing commands included in the drawing commands is generated, and the generated moving image data and the clipped graphics are composed and output.

Image processing apparatus and control method thereof

An aspect of the present invention includes a detection unit configured to detect content of second drawing data drawn in a second window, which is displayed on a lower layer of a first window, and a display control unit configured to control display by determining, based on the content of the second drawing data, whether to perform first control, in which the second drawing data is displayed in an overlap region, which is a region in which the first window and the second window overlap, in such a way as to be visible in the first window, or second control, in which the second drawing data is not displayed in the overlap region or the second drawing data is displayed in such a way as to be less visible in the first window than when the first control is performed.

Display control apparatus and method for displaying overlapping windows

An image processing apparatus and its control method receives a drawing command including a moving image drawing command and a graphics drawing command and performs drawing processing. A drawing command is received, and the moving image drawing command is separated from the graphics drawing command. A graphics drawing unit obtains the result of graphics drawing in accordance with the graphics drawing command. A moving image drawing unit generates moving image data processed in accordance with the moving image drawing command. A composition unit composes the result of graphics drawing by the graphics drawing unit with the moving image data generated by the moving image drawing unit.

An image-processing apparatus is provided. The apparatus includes a determining unit determining a type of image data; a holding unit holding color value for the still images, and holding a ratio for the moving image for each moving image, an updating unit updating the color value and the ratio, and a display unit displaying composite image data. For each piece of image data to be drawn, the updating unit updates each ratio based on a transmittance of the image data, updates the color value and a transmittance of a still image when it is a still image, and updates the color value data based on a transmittance of a moving image, and causes the transmittance to be further held as a ratio of the moving image when it is a moving image. The display unit displays the composite image data using the color value and the ratio.

Image-processing apparatus, method for controlling thereof, and computer program

An image processing apparatus processes vector image data in units of blocks. When vector image data associated with a first block satisfies a predetermined condition, the image processing apparatus stores the result of processing the vector image data associated with the first block. When vector image data associated with a second block matches the vector image data associated with the first block, the image processing apparatus outputs the result of processing the vector image data associated with the first block, which is stored therein.

Image processing apparatus and method for processing vector image data units of blocks

An image processing apparatus that are capable of reducing the time required for image formation processing to generate image data from drawing data. A block segmentation section determines an encompassing region encompasses an object to be drawn and determines whether or not each of segments into which one page is segmented in a grid pattern overlaps the encompassing region. Image processing sections process segment by segment an object encompassed by an overlapped encompassing region.

Image processing apparatus, image processing method, and image processing program

An image forming apparatus that converts page description language to page description language corresponding to a plurality of areas; generates image data based on the converted page description language; retains the converted page description language and the generated image data; compares the retained page description language and the converted page description language; and selects one of the generated image data and the retained image data, depending on the comparison result.
